The refractories for steel industry produced by our company mainly include the following types:
High Strength Wear-Resistant Ceramic Castable
Ceramic wear-resistant castables now account for a considerable proportion of the energy and economic cost consumption in industrial fields such as cement plants, thermal power plants, and metallurgical mines. Taking the cement industry as an example, downtime caused by wear accounts for 50%-55% of the total downtime.
Clay Refractory Bricks For Casting
Refractory bricks for casting refer to clay bricks used in the process of pouring molten steel from a ladle into an ingot mold. They include ladle lining bricks and bricks for steel casting (including sleeve bricks, plug bricks, nozzle bricks, seat bricks, funnel bricks, center casting pipe bricks, center bricks, flow bricks, flow tail bricks, and ingot mold bottom bricks).
High Alumina Refractory Bricks For Casting
Ingot high alumina bricks refer to sleeve bricks, plug bricks, nozzle bricks and seat bricks in steel ladle. In 1954, China first successfully trial-produced high aluminum plugs and nozzle bricks in Chongqing No. 1 Iron and Steel Plant, replacing clay bricks, thus overcoming the frequent steel leakage accidents in steel casting.
Andalusite Refractory Bricks For Foundry
Red pillar stone bricks are mainly made of corundum, red pillar stone, and other raw materials, and the particle size of the raw materials is strictly controlled, New processes are applied, and multi-level batching, matrix homogenization, and determination of the best calcination temperature and other process measures are adopted.
Application of Refractories For Steel Industry
Steel Industry
Widely used in the steelmaking process to line furnaces, ladles and tundishes, refractories are exposed to the harsh conditions of molten metal and slag. In steelmaking, they are typically consumed and replaced on a regular basis due to the extreme nature of the steel production environment. The choice between brick and monolithic refractory linings depends on the specific needs of the furnace or vessel, with each form offering different advantages in terms of installation, maintenance and performance.
Ceramics Industry
For the ceramics industry, refractories are present in the manufacturing of both traditional ceramics, such as bricks and tiles, and advanced ceramics used in high-tech applications. These refractories line the kilns and furnaces where raw materials are fired at high temperatures to form ceramic products. The properties required for refractories in this industry include high thermal stability, resistance to chemical corrosion from glazes and fluxes, and the ability to withstand thermal cycling without cracking. Both brick and monolithic refractories are utilized, with the choice depending on specific operational requirements such as temperature uniformity and ease of maintenance.
Cement Industry
With heavy reliance on refractories, especially in the kiln where limestone and other materials are heated to produce clinker, the refractory linings formulated for cement kilns must withstand the required high temperatures in addition to the mechanical abrasion and chemical attack from alkalis and acids. Monolithic refractories are often preferred because of their ability to form uniform linings that minimize heat loss and resist mechanical wear.
Glass Manufacturing
In glass manufacturing, refractories are used to construct and line the furnaces and tanks in which glass mixtures are melted. Key requirements for refractories in this sector include resistance to high temperatures and the ability to prevent glass contamination. Both brick and monolithic refractories are used, with selection based on resistance to thermal shock and influence on glass purity.
