Safe operation of ladle

The ladle is a special container that load high-temperature molten steel. It is an important equipment linking the converter and continuous casting production. It is a major risk in steelmaking production that needs to be strictly controlled. Ladle operation is very demanding on safety. The ladle workshop of the steelmaking plant is not only responsible…

[Original Article] Magnesia-carbon brick, Ladle, slag line brick, Uneven erosion

Magnesia-carbon brick is a high-quality refractory material. Because this kind of carbon-containing refractory product has the advantages of high refractoriness, good slag corrosion resistance, strong thermal shock resistance and low high temperature creep, it is widely used in electric furnaces, converters and ladles.   The service life has been greatly improved. At the same time,…

[Original Article] Reduce the superheat of molten steel by 10-50°C! Introduction of a new type of multi-graphite electrode tundish plasma heating system!

The production practice of continuous casting has proved that low molten steel superheat can refine the grains of continuous casting slab and reduce center segregation; constant temperature and low superheat casting can reduce and maintain the heat flux density, thereby preventing breakout and corner cracks of the slab; only available The system of tundish molten…

[Original Article] Steel ladle capacity-increasing transformation and optimizing practice of ladle bottom technology

After a company’s capacity expansion ladle went online, the quality of molten steel was increased from 290t to 310t, which directly laid the foundation for stable production and excellent production in the steelmaking department. The annual production capacity of the first steelmaking converter increased by 7% to about 630,000 tons. The total annual production capacity…

[Original Article] Why continuous feeding is so hot, electric steelmaking output doubled! Daily production of 40-50 furnace!

Continuous feeding: the scrap steel is loaded into the conveyor or rail car with electromagnetic chucks, hydraulic grabs, and baskets, and is automatically and continuously added to the arc furnace from the upper part of the furnace shell on the side of the electrode no.1 and no.2 of the arc furnace. Afters that, the scrap…
