Product Description

Covering agent/Thermal insulation to avoid heat dissipation, purification of liquid steel

 

Product description:

 

Proper temperature of molten steel is a necessary condition to ensure the smooth casting of molten steel into qualified ingot.In order to avoid direct exposure of molten steel in the ladle to the air, which causes the temperature of steel in the casting process to drop too fast, a certain amount of coating agent must be added to the surface of molten steel for heat preservation after the converter is discharged.Covering agent insulation to avoid heat dissipation;The covering agent isolates the air to prevent the oxygen in the air from entering the molten steel and causing secondary oxidation, which affects the quality of the steel.The coating agent absorbs and dissolves the inclusions that float up from the molten steel to the surface of the slag to purify the molten steel.Suitable for ladle, tundish, ladle, torpedo type mixed iron car.
