What are the measures to improve the purity of continuous casting steel

Purity refers to the quantity, shape and distribution of non-metallic inclusions in steel. The inclusion in steel shall be reduced to the required level according to the steel grade and product quality,

We should start from the following five aspects:

① Reduce [O] content in steel as much as possible.  

② Prevent the molten steel from interacting with air.

③ Reduce the interaction between molten steel and refractory materials.  

④ Reduce slag entrainment in molten steel.  

⑤ The improved flow promotes the floating of inclusions in molten steel.

In terms of process operation, the following measures shall be taken:

(1) Slag free tapping: slag retaining balls are adopted for the converter and eccentric bottom tapping is adopted for the electric furnace to prevent a large amount of slag from falling into the ladle.  

(2) Ladle refining: select the appropriate refining method according to the steel grade, to uniform the temperature, fine tune the composition, reduce the oxygen content, remove gas inclusions, etc.  

(3) Non oxidation casting: after the molten steel is treated by ladle, the total oxygen content in the steel can be reduced from 130ppm to below 20ppm. If the injection flow from ladle to tundish is not protected or poorly protected, the total oxygen content in tundish steel will rise to the range of 60-100ppm, which will return to the level before external refining, and the effect of external refining will be wasted.  

(4) Tundish metallurgy: the tundish adopts large capacity, and the addition of retaining walls and dams is an effective measure to promote the floating of inclusions. For example, for 6T tundish, the scrap rate of slab inclusion is 12%, and the inclusion is 0.82 pieces / m2; 12t tundish + retaining wall, 0 scrap inclusion in slab, 0.04 inclusions / m2.

(5) Submerged nozzle + casting mold powder: the mold powder shall be able to fully absorb inclusions. The submerged entry nozzle material, nozzle shape and insertion depth shall be favorable for the floating and separation of inclusions.

no wait the best part is the tundish bit. Stephen meets an English priest trying to light a fire and says ‘use the tundish’ and the priest isn’t familiar with that word. A good young identitarian Stephen gets very excited that he knows the word but the priest doesn’t—-it must be an Irish word! and then in the journal part at the end in another throwaway line Stephen apparently looked it up and no, tundish is English, the guy just didn’t know the word.

What are the prominent problems in the tundish

At present, there are many problems in the tundish used in China, especially in the tundish used for billet caster.

The specific performance is as follows:

(1) The shape of tundish cavity is unreasonable. Due to the unreasonable shape of the inner cavity, the flow of molten steel in the tundish is unreasonable and the residence time is short, which can not purify the molten steel. The distance from the drop point of the large ladle injection into the tundish to the tundish nozzle is short, or the distance from each nozzle is too different; The volume at the drop point of the ladle is too small, resulting in serious steel slag mixing and lining scouring, affecting the service life of the tundish and polluting the molten steel.

(2) The capacity of tundish is small and the depth of molten pool is shallow, so it is not suitable for high-speed caster. The molten steel stays in the tundish for a short time, which makes it difficult to purify the molten steel and remove inclusions; It is difficult to maintain constant casting speed when changing the package; During pouring, the steel slag in the tundish is agitated seriously, which makes it difficult to float the inclusions and easy to enter the mold, especially when changing the tundish.

(3) The position of tundish nozzle clogging is not properly designed, especially the nozzle on both sides is too close to the two sides, which is easy to cause unsmooth pouring of the two side nozzles.

(4) The tundish nozzle control device is too thin and unreliable, which makes it difficult to accurately control the flow of molten steel, making it difficult to stabilize the liquid level of the mold and often causing out of control accidents.

(5) The large deformation of tundish and the problems of design and manufacturing accuracy result in insufficient centering accuracy of multiple water outlets.

(6) The lifting device of tundish is ineffective, and most of them can not be lifted, which brings difficulties to the continuous casting process and causes many defects of the slab.

(7) The distance from the bottom of tundish to the upper mouth of crystallizer is improperly selected. Most of the distance is too high, which makes it difficult to align the nozzle, and also makes the nozzle too long, which increases the refractory consumption per ton of steel nozzle.

(8) Insufficient attention has been paid to the quick change technology of submerged entry nozzle.

The above tundish can only be used at low casting speed, which is not suitable for the requirements of high casting speed. Modern tundish should not only adapt to the conditions of constant speed casting at high drawing speed, high steel throughput and strength, and intense agitation in the tundish, but also play the role of purifying molten steel and removing inclusions.

The specific measures adopted include:

(1) Optimize the shape of the inner cavity of the tundish, make the liquid steel flow reasonably in the tundish, expand the volume of the large ladle at the drop point of the tundish and optimize the distance from the drop point of the large ladle to each water inlet under the condition of adapting to the high pulling speed;

(2) Tundish with large capacity deep melting bath;

(3) Prevent deformation of tundish shell;

(4) Adopt firm and reliable tundish nozzle control device;

(5) Adopt reliable tundish lifting device under load;

(6) Optimize the distance from the tundish to the upper mouth of the crystallizer.

Defect name: Holes Record No.: 1443 Type of defect (Internal/Surface): Internal, surface Defect classification: Slab defects Steel name: Steel Steel composition in weight %: No data. Note:  For this study we only selected the steel charges which were cast into pipe billets Ø250mm respectively Ø270mm, using all steel grades (carbon, low-alloyed, respectively alloyed) used in making these two types of pipe billets. The holes are cavities on the external surface or in the under-shell area of the billet at about some tenths of millimeters from the shell surface and they are presented in figure 1. They have a diametre up to 3mm and a length (depth) that can reach 25 mm. As usually they contain CO, H2, Ar and most of all they are associated with the inclusions. In case that they are superficial and/or few, these are polished (ground). They are determined by: the insufficient deoxidation of steel (gases occurrence: hydrogen, nitrogen, oxygen), the quality and humidity of the casting powder, the quality and homogeneity of its distribution, the variation of the steel level in the mould and the humidity existence in the refractory clay work of the tundish.

Continuous Casting Machine Manufacturers: Turning Molten Metal into Usable Shapes

Have you ever wondered how metal objects, like car parts or pipes, are made with such precision and consistency? The answer lies in a fascinating process called continuous casting. Behind this process are the continuous casting machine manufacturers, the unsung heroes that enable the transformation of molten metal into various usable shapes. In this article, we'll take a journey through the world of continuous casting, breaking down the technology and its importance in a way that anyone can understand.

Understanding Continuous Casting

Imagine a river of molten metal flowing down a channel. Continuous casting is a method that takes this concept and applies it to the production of metal products.
