 TOPCHASE  tundish and ladle  covering agent, which has excellent thermal insulation performance, moderate slag consumption, good spreadability, strong ability to prevent secondary oxidation of molten steel and absorption of non-metallic inclusions, it is beneficial for protecting ladle and tundish lining.



1. Designed with CaO-SiO2-MgO and CaO-AL2O3-SiO2 , the melting temperature is suitable and controlled at 1350±50°C.

2. The C content is controlled at 15-25%, which not only controls the melting speed, but also does not increase the carbon content of the molten steel,and insulation effect is good.

3, Adding other  heating materials that can be expanded, volume expansion caused by high temperature,which can have good thermal  insulation,and aviod secondary oxidation.

4. The alkalinity is controlled at 1.6-1.8 and 1.0, which not only improves the ability to adsorb inclusions, but also protects the tundish and ladle lining.

6, using particle ball technology to solve the dust pollution on site to ensure clean production.
