Slagging constituent and method for recovering electrical steel waste through slagging and remelting

Slagging constituent and method for recovering electrical steel waste through slagging and remelting

The invention discloses a slagging agent and a method for recovering electrical steel waste through slagging and remelting. The slagging agent is prepared by mixing CaO powder, SiO2 powder, CaF2 powder, K2O powder and Na2O powder according to the mass ratio of (0.40-0.55): (0.45-0.60): (0.05-0.10):...

description The invention discloses a slagging agent and a method for recovering electrical steel waste through slagging and remelting. The slagging agent is prepared by mixing CaO powder, SiO2 powder, CaF2 powder, K2O powder and Na2O powder according to the mass ratio of (0.40-0.55): (0.45-0.60): (0.05-0.10): (0.04-0.10): (0.01-0.05). The method for recovering the electrical steel waste through slagging and remelting comprises the following steps: uniformly mixing slag former powder, putting the slag former powder into a reaction container, heating the slag former powder in an inert atmosphere until the slag former powder is completely melted, adding the electrical steel waste into the reaction container, adding a monatomic silicon ingot after the electrical steel waste is completely melted, melting the monatomic silicon ingot, uniformly stirring the monatomic silicon ingot and the monatomic silicon ingot, and keeping the temperature at 1500-1550 DEG C for 40-60 minutes, and cooling and removing a slag layer at the uppe
