we offers an extremely wide range of materials for lining blast furnaces depending on the specific installation conditions and loading. Highly wear-resistant and temperature change-resistant corundum brick pre-fired at up to 1700 °C withstands the mechanical stresses in the top of the blast furnace where the burden is introduced. The reduction zones below that use special shaped bricks made of fireclay and andalusite which provide outstanding reduction resistance.
The steel making process involves several stages of thermal and chemical treatment requiring a variety of refractory linings that are compatible with many application conditions.
Steel Making :
The steel making process represents the metallurgical sector involving the pig iron transformation into steel, its transport and refining until the molding stage. This highly corrosive process requires refractory materials with excellent resistance to steel and basic slag corrosion, as well as high mechanical resistance to hot and low rates of erosive wear
We provide innovative solutions from project stage to refractory application offering high performance and cost reduction for sectors including:
- Electric arc furnace (EAF)
- Pig iron steel
- Steel ladle
- Basic oxygen furnace (BOF)/Converter LD
- Tundish
- Continuous casting
- Slide gate system
