Slag Ladle

Slag ladles are essential equipment for steelmaking production in metallurgical enterprises. The company's slag ladles are 

integrally cast and have strong resistance to deformation. The current advanced cast steel process and software system 

make the cast slag pot production cycle short and the service life is much higher than the market.

Production Process

a)CAE Modeling

Before the pouring, the casting process was numerically simulated by CAE software, and the process analysis and quality 

prediction of the product forming process were carried out, and the slag casting process was continuously optimized. 

The metallurgical aids are complete in set and the overall size is well controlled. The water glass sand molding process 

can prevent the occurrence of hot cracks in the castings. At the same time, the pit shape is adopted, which is not affected 

by the season and has high production efficiency.

b)Casting, Heat Treatment

The qualified raw and auxiliary materials shall be put into the electric arc furnace for smelting in proportion, and the molten 

iron shall be sampled for spectral analysis. After passing the test, the pouring shall be carried out according to the principle 

of “low temperature fast pouring”, and the pouring time and temperature shall be recorded. For the problem that the carbon 

content difference between the trunnion alloy steel and the tank carbon steel is relatively large, we have customized a com-

plete process to strictly control the welding problem in the production process.

c)Sanding, Flaw Detection

The professional grinding and finishing team performs operations such as cutting and pouring risers and flashing edges. 

With large-scale shot peening equipment, it can effectively improve the appearance quality of slag irrigation, make its 

surface finish meet customer requirements, and use advanced flaw detection equipment to carry out non-destructive 

testing of each slag irrigation to ensure the internal quality of slag irrigation and strictly eliminate Any defective products 

are shipped.
