Text
Introduction of Monolithic Refractory Products
Monolithic refractory products are a type of unshaped refractory material that is used to create a seamless, protective lining in furnaces, kilns, and other high-temperature applications. Unlike traditional shaped refractories, which are made from pre-formed bricks or tiles, monolithic refractory products are installed in a plastic or dry state and then cured to form a hard, monolithic structure.
Advantages of Monolithic Refractory Products
Monolithic refractory products offer several advantages over traditional shaped refractories, including:
Versatility: Monolithic refractories can be cast, vibrated, gunned, or rammed into place, making them suitable for a wide variety of shapes and applications.
Joint-free construction: Monolithic refractories create a seamless lining that is less susceptible to gas leaks and heat loss.
Improved strength and durability: Monolithic refractories can be made to be stronger and more durable than traditional shaped refractories, as they are not limited by the size and strength of individual bricks or tiles.
Ease of repair: Monolithic refractories can be easily repaired by patching or resurfacing, which can extend the life of the lining.
Types of Monolithic Refractory Products
There are several different types of monolithic refractory products available, each with its own unique properties and applications. Some of the most common types include:
Castable refractories: Castable refractories are mixed with water or a liquid binder and then poured into place. They are typically used for applications where a smooth, monolithic surface is required.
Plastic refractories: Plastic refractories are pre-mixed with a binder and can be formed by hand or with a tool. They are often used for patching and repairs.
Ramming mixes: Ramming mixes are dry materials that are compacted into place using a hammer or press. They are typically used for applications where high density and strength are required.
Gunning mixes: Gunning mixes are dry materials that are sprayed onto a surface using a pneumatic gun. They are often used for large-scale applications or for applications where access is limited.
Patching mixes: Patching mixes are used to repair damaged areas of monolithic refractory linings. They are typically made from the same type of material as the original lining.
Applications of Monolithic Refractory Products
Monolithic refractory products are used in a wide variety of applications, including:
Industrial furnaces: Monolithic refractories are used to line industrial furnaces used for processes such as metal melting, heat treating, and incineration.
Kilns: Monolithic refractories are used to line kilns used for firing ceramics, glass, and other materials.
Power plants: Monolithic refractories are used to line boilers and other components in power plants.
Petrochemical plants: Monolithic refractories are used to line reactors, crackers, and other components in petrochemical plants.
Waste incineration: Monolithic refractories are used to line incinerators used to dispose of hazardous waste.
Choosing the Right Monolithic Refractory Product
The type of monolithic refractory product that is right for you will depend on a number of factors, including the specific application, the desired properties of the lining, and the budget. It is important to consult with a qualified refractory specialist to get the best possible recommendation.
Installation of Monolithic Refractory Products
The installation of monolithic refractory products should be done by experienced and qualified personnel. The specific installation process will vary depending on the type of product and the application. However, some general steps include:
Surface preparation: The surface to be lined must be clean, dry, and free of debris.
Mixing: The refractory material is mixed according to the manufacturer's instructions.
Application: The refractory material is applied using the appropriate method (casting, vibrating, gunning, or ramming).
Curing: The refractory material is allowed to cure according to the manufacturer's instructions.
Maintenance of Monolithic Refractory Products
Monolithic refractory products should be inspected regularly for signs of wear or damage. Damaged areas should be repaired promptly to prevent further damage to the lining. Regular maintenance can help to extend the life of the lining and reduce downtime.
Monolithic refractory products are an essential component of many high-temperature applications. They offer a number of advantages over traditional shaped refractories, including versatility, joint-free construction, improved strength and durability, and ease of repair. With the right product selection, installation, and maintenance, monolithic refractory products can provide years of reliable service.
Additional Tips
When selecting a monolithic refractory product, it is important to consider the chemical environment in which it will be used. Some refractory materials are more resistant to certain chemicals than others.

EAF working layer refractory materials
EAF is widely used for nowever days steel making industries. For this?furnace, the key point effecting service life is working layer. Working layer would touch with melton steel directly, where is of high thermal load, heavy chemical mechanical erosion. So high quality refractory materials should be adapted in working layer.
Regular lining method for EAF working layer is namely sintering, vibrating and brick-construction. For brick-construction method, asphalt binder magnesia brick is widely used. For sintering and vibrating method, magnesia sand with tar as bonding agent are normally used. In nowever days, brick-construction and sintering method are gradually eliminated because of low service life and less applicability. For high power EAF, dry magnesia vibration mix is widely used. After powerful ramming and the density requirement, the mix can be sintered into overall under certain temperature, and a good service life can appear. In regular condition, service life of vibration mix can reach 300 heats. After one time hot-repairing, the service life can be as long as 500-600 heats. With this method, furnace stopping time would decrease, and steel unit cost would also low down by a large degree, then the steel plant profit would increase a lot.

What are the refractory materials for the bottom of the AC EAF
The AC EAF has a long history of steelmaking, so its refractory materials for the bottom of the furnace have also undergone changes. The bottom of the furnace is rammed with asphalt tar magnesia or brine magnesia. Because brine magnesia is eroded quickly at the bottom of the furnace, it cannot meet the requirements for use. Although asphalt tar magnesia has better durability, it is troublesome to construct and has environmental pollution. Therefore, more magnesia bricks and low-grade magnesia-carbon bricks are used to build the bottom of the furnace. The durability of the brick-built furnace bottom is very good, but the masonry is labor-intensive and time-consuming.
By the 1990s, my country began to use the furnace bottom dry ramming material. It is simple and convenient to construct, and does not need to be baked. After the construction is completed, it can be directly used for steelmaking. The material is magnesium calcium iron dry vibrating ramming material. Using the low melting point calcium ferrite it contains, when the temperature rises above 1200 °C, it can quickly sinter to produce strength. Under the hydraulic pressure of molten steel, it can rapidly sinter and shrink, the shrinkage reaches 4% to 5%, and the bulk density increases to more than 3.0 g/cm3. Has particularly good corrosion resistance and good use results. The consumption of steel per ton of refractory materials is reduced from 4 to 8 kg of asphalt magnesia bricks to less than 2 kg. Some modern EAF bottom dry materials consume as little as 0.3 kg per ton of steel, which is mainly corresponding to the steelmaking process technology; In the process of use, the material is sintered layer by layer, sintered and densified near the molten steel, resisting The erosion and scouring of molten steel, the transition layer is under the sintered layer, and the loose non-sintered layer is under it. This loose layer has low density and low thermal conductivity, which play an important role in the insulation of the EAF. After years of promotion and development, the vast majority of electric furnace bottoms in my country use this kind of ramming material.
The construction and use of the furnace bottom dry material are the key factors affecting the use effect. The bottom material should be called dry vibratory castable more appropriately. Because the vibration densification density of the material is more than 0.2g/cm3 higher than that of ramming, the erosion resistance will be significantly improved. Kairuid kiln believes that the dry material should be vibrated for construction, especially for the DC EAF bottom that is not easy to be repaired. When repairing, the slag and scrap steel at the bottom of the furnace must be cleaned up, otherwise the steel slag under the repairing material may melt when used to a certain extent, and the furnace bottom material will float up under the impact of the steel block. When tapping, the floating bottom block may block the tapping hole and affect the tapping. In the process of use, the furnace bottom should be observed at any time. When there is a floating, it should be repaired in time (generally, the same kind of material can be filled to the pit) to prevent the floating from further expansion and prevent the occurrence of steel breakout. It is worth noting that when using in the first few furnaces, due to the thin sintered layer, the ability to withstand the impact of scrap steel is weak, so light and thin materials should be added, and the feeding basket should be lowered to prevent the scrap steel from having a large impact on the bottom of the furnace.

Brief introduction of tundish lining coating
In the process of steelmaking, the tundish is the transition device between the mold and the ladle. The use of the tundish can make the molten steel better and more smoothly injected into the mold, and can ensure the stability and stability of the molten steel and the effect of cleaning the molten steel. Therefore, the tundish is used in steelmaking. The role in the process cannot be underestimated. This article briefly introduces the characteristics and technological process of the tundish dry vibrating material.
The refractory materials used in the tundish are more miscellaneous and the turnover is fast, so the refractory dry vibrating material is a consumable material. The tundish refractory lining mainly includes thermal insulation layer, permanent layer and working layer. The thermal insulation layer of the tundish has been using thermal insulation fibers or thermal insulation bricks with little change. In the mid-1970s, the permanent layer was mainly built with clay bricks, and later with high-alumina bricks. At first, the working layer and permanent layer of the tundish were integrated, and most of them were made of clay bricks. However, with the development of metallurgical technology, clay bricks as the working layer and permanent layer of the tundish could not meet the requirements for service life, and they were damaged by corrosion. Seriously, causing molten steel to be contaminated in the tundish. Later, the permanent layer was cast as a whole using high-alumina castables. In the early days of the working layer, aluminum refractory bricks were used. Later, in order to keep the temperature change of the molten steel in the tundish not exceeding 15 °C during casting, the working layer began to use a thermal insulation board. Replaced by refractory paints and refractory spray coatings, with the development of tundish refractories, the latest dry vibrating materials have begun to replace spray coatings with significant advantages. The refractory material for the tundish working layer has gone through the development of refractory clay brick (permanent layer is working layer), thermal insulation board, spray paint (spray material) and the latest dry vibrating material (ie dry working lining).
