Description parameter

This product is a calcium aluminate material specially developed for meeting the special needs of steelmaking as refining agent for steelmaking.

Refining is the key to quality control of molten steel from steelmaking furnaces(converters to electric furnaces)to continuous caster.The key feature of successful ladle smelting is to control the slag,and the steelmaking rafining agent is specially designed for this purpose.It has the requiared chemical and physical properties.

This product is a pure calcium aluminate salt.It is made from a special melting furnace and its composition is stable.

This product is easy to dissolve at steelmaking temperature.It has good desulphurizing capacity and can quickly form Desulphurizing Slag.And H excellently removes non-metallic inclusions and deoxidization from steel until the molten steel is finally purified to get clean steel.

This product does not contain fluorine ingredients,can reduce the erosion of refractory and the air pollution.

This product is a very good surface slag that prevents molten steel from absorbing gases from the atmosphere.
