Working Principle and Identification Method of Deslagging Agent

Resources

1. What is deslagging agent?


Deslagging agent is the product of slag gathering and slag removing of iron cast steel, used for smelting and slag removing of cast steel, alloy steel, special steel and non-ferrous casting.


Deslagging agent is used for cleaning and slag gathering in the later stage of iron smelting. It is usually used in ladle, crucible furnace, reverberatory furnace and electric furnace, which can make the slag quickly accumulated, ensuring the cleaning of the molten liquid. Next, Jinzhou Sata Fused Fluxes and New Materials Factory will explicit the working principle of the deslagging agent.


After the metal finishes melting in the electric furnace, you sprinkle a little deslagging agent on the surface of the metal liquid for the preliminary slag removal and then sprinkle a thin layer to cover the surface of metal liquid because this can play a double role of heat preservation and slag gathering and finally remove slag before the metal liquid comes out of the furnace. Or you can sprinkle a little deslagging agent at the bottom of ladle when the molten steel is discharged.


2. How to the identify deslagging agent?


You can choose deslagging agent with good quality through such aspects as slag removal effect, usage and dosage. Deslagging agent neither causes dust nor contains toxic substances, thus it can improve the working environment and reduce the risk of occupational diseases. In addition, good slag removal agent into the ladle shall have some viscosity which can accumulate slag piles, as well as certain strength which is convenient to pick out the slag and save slag removal time. Good deslagging agent sprinkled on the surface of liquid metal can expand at high temperature to form a viscous active material with porous structure. It can adsorb the inclusions in the metal liquid and form a thin shell to collect and remove the slag. It is beneficial to purify molten steel and molten iron and improve the quality of casting.
