Product description

Parameters

　　Precast blocks for tundish mainly include slag retaining wall and dam and impingement plate or cup. The major raw materials are sintered magnesia, fused magnesia, super bauxite, synthetic magnesia-alumina spinel, synthetic magnesia-chrome sand, etc. with SiO2 and Al2O3 ultrafine powder as binders. It features great anti-erosion and slag erosion performance. The impingement cup can help improve the flow field distribution of molten steel in tundish to improve slab quality.

Products

Slag retaining wall, slag retaining dam

The prefabricated blocks used in the tundish mainly include slag retaining walls, slag retaining dams and impact plates or impact cups. The main raw materials are sintered magnesia, fused magnesia, super high alumina bauxite, synthetic magnesia-aluminum spinel, synthetic magnesia -chrome sand, etc., with SiO2 and Al2O3 ultrafine powder as binders. It has strong resistance to erosion and slag erosion. The impact cup improves the flow field distribution of the molten steel in the tundish, thereby improving the quality of the slab.
