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…

strip production-hot rolling technology

The key technology of hot strip production-hot rolling technology

The “Integration of Steelmaking, Continuous Casting and Rolling” plan integration and scheduling technology, automatic control technology and comprehensive shape control technology have been developed into key common technologies in the production process of hot-rolled wide strip steel, which are important for energy saving, product quality control, and enterprise economy. Increased efficiency is decisive.   The…

Magnesia-carbon brick, Ladle, slag line brick, Uneven erosion

[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…

Research and Analysis on Defects of Continuous Casting Billets

[Original Article] Research and Analysis on Defects of Continuous Casting Billets

There are three four-machine four-strand continuous casters in the second steelmaking plant of Anyang Iron and Steel Co., Ltd., two arc-shaped radii of 5250mm, and one arc-shaped In the production process, the quality defects of the cast slab fall off sometimes appear. As a unique shape of billet continuous casting shape defect is a quality…

Achieve the maximum casting speed of the 6m arc 165 billet continuous casting machine is 2.6-2.7m/min

The main task of the continuous casting operation area is making molten steel into qualified slabs. The indispensable thing is cooling water. Whether the cooling water can be used correctly is related to the continuous casting machine breakout accident and the quality control of the slab. The engineer operated the following points: In order to…
