Product Description

Ladle covering agent/No slagging, no erosion lining, no crust, extend ladle service life/Purifying molten steel


Product description:


Ladle covering agent refers to an covering agent which is added on the surface of steel liquid and takes thermal insulation as its main performance.

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.



Suitable for ladle molten steel surface covering insulation, its significant advantage is that after the addition of ladle can automatically crush on the surface of molten steel can be quickly spread, to achieve the full coverage of molten steel, the formation of a three-layer molten structure, to prevent the secondary oxidation of molten steel and thermal radiation, adsorption of molten steel surface harmful inclusions.
No slagging, no carburizing, no etching lining, no crusting, extend the service life of ladle, easy to use, reduce labor intensity.
