Brief introduction of magnesia-carbon brick raw material

1. Fused magnesia sand: it is an alkaline refractory made of natural magnesite, light fired magnesia or sintered magnesia fused by an arc furnace. Fused magnesia main crystal phase of periclase, melting point is 2800 ℃, 1600 ℃ sublimation in vacuum, in reducing atmosphere above 2000 ℃ sublimation, is greater than 3.40 g/cm3 density, porosity of 0% to 10%, 5.5 mohs hardness, resistance to basic slag erosion is very strong, stable chemical properties, under the high temperature of 1500 ℃ and other than the silica brick no or weak reaction between all kinds of refractory materials. The appearance should be clear after the complete melting crystallization, do not allow mixing with other magnesia or sundries.

2, Graphite: is a carbon as the main component of the natural mineral, it has high temperature resistance, heat conduction, electricity, lubrication, plastic and corrosion resistance and other properties. It is the main material containing carbon resistant material. The graphite used in refractory is flake graphite, which is divided into high purity, high carbon, medium carbon and low carbon graphite according to the fixed carbon content. The color is iron black, steel gray. The density is 2.09-2.23g/cm3 with a melting point of 3700℃±100℃(in vacuum), high thermal conductivity, small expansion coefficient, small elastic modulus, good lubricity, good conductivity, stable chemical properties, no reaction with acid, alkali and organic solvents at room temperature, and steel solution is difficult to wet, with good anti-erosion performance. 3. Phenolic resin: it is a non-aqueous organic binder for refractory materials. It is prepared by condensation of phenol (or cresol, dicresol, or resorcinol) with formaldehyde (or glycolaldehyde) under the action of catalyst.?

The main advantages are

(1) high carbonization rate (52%);

(2) good adhesion, high strength of the formed body;

(3) high bonding strength after burning;

(4) the rate of hardening can be controlled at room temperature;

(5) less harmful substances, can improve the operating environment.

According to heating properties or structural morphology classification, there are thermosetting phenolic resin and thermoplastic phenolic resin, according to product morphology classification, there are liquid phenolic resin and solid phenolic resin (granular and powder), according to the curing temperature classification, there are high temperature solidified type 130℃-150℃; There are medium temperature fixed type 105℃-110℃; There are room temperature solidified type 20℃-30℃.g material.

Industrial Remnants, Niles, O. - According to a 1909 Sanborn fire map, these are the last two structures left standing (that I’m aware of) from the Niles Firebrick Co. The house in the front served as the offices, the three story brick structure was the pattern shop. I read that Niles Firebrick recruited heavily in Italy. You can thank them for the many Italians that live/lived in the south side of Niles. #therustjungle #steelvalley #deindustrialization #niles #nilesohio #refractory #refractorybricks #firebrick (at Pantalone & Son Towing) https://www.instagram.com/p/BpPelt8HPoI/?utm_source=ig_tumblr_share&igshid=j0j8myqf398v

What Refractory Castables Are Used in Various Parts of The Cement Kiln?

. . . These are materials manufactured as cement-based products that have a high tolerance for heat, wearing, and resistance to corrosive chemicals. Refractory castables are used within different parts of a cement kiln to ensure that the structure is intact and can operate over a long period of time.

Cold crushing strength and high temperature crushing strength of refractory brick

Cold crushing strength

Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature.

The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better.

The high crushing strength indicates that the processed quality is good, structure is uniform, and well sintered.

High temperature crushing strength

High-temperature crushing strength is the refractory products under the specified high temperature conditions, the unit area can withstand without damage.

The high temperature crushing strength of refractory products determines the use scope, which is an important basis for the use of refractory materials.

High temperature crushing strength indexes are also meaningful to unshaped refractories, especially refractory castables and fire-resistant plastic materials. So the high temperature crushing strength is more important.

Refractory Work Procedures and Tips to Choose Methods

Now, who has not heard of refractory materials? Refractory materials, such as refractory bricks, are the unsung heroes of many industrial processes. Designed to withstand extreme heat, these specialized materials work wonderfully when it comes to protecting critical equipment such as furnaces, kilns, and reactors.

Nanotechnology improves the thermal shock resistance of low-carbon magnesium-carbon refractory materials

In addition to good slag resistance, low-carbon magnesia-carbon refractories also require products with a certain degree of thermal shock resistance. This is due to the sharp decline in thermal shock resistance due to the reduction of carbon content. Thermal shock resistance is not only an important index to measure refractory materials, but also a key research direction in the low-carbon use of magnesia-carbon bricks.

Nano powder particles have the characteristics of small size, large surface energy and large dispersion, which are conducive to the relative slip between particles and can improve their thermal shock resistance. Therefore, the use of nanotechnology to improve the thermal shock resistance of low-carbon magnesium-carbon refractories has attracted much attention. The use of nanotechnology to improve the thermal shock resistance of low-carbon magnesium-carbon refractories is essentially to increase the fracture toughness of the material. The microstructure of the material can be adjusted to further increase the crack propagation resistance of the material. There are two main toughening methods for low-carbon magnesium-carbon refractories.

?(1) Crack deflection toughening, nano-powders are introduced in the form of refractory raw materials or additives, and the introduced nano-powders are dispersed and distributed in or between particles. A large number of sub-interfaces are formed and play a role in pinning dislocations, making the crack propagation path more tortuous, extending the crack propagation path, resulting in an increase in the ability of the crack to be consumed during the propagation process, and an increase in the fracture toughness of the material.

(2) Crack bridging and toughening, introducing nanoparticles into the refractory aggregates can form bridging components of fibers, whiskers and ceramic phases in situ. When larger bridging components are encountered in the process of crack propagation, their existence is relatively high. The bridge connecting element is equivalent to erecting a bridge between two opposing crack surfaces, which increases the resistance of crack propagation. If the cracks continue to expand further, the bridging component is destroyed by pulling out from the matrix. This pulling out process will consume a lot of energy and increase the fracture toughness of the product, thereby improving its thermal shock resistance.
