The two materials of electrode paste and smelting flux seem to have nothing to do with each other, but many engineers in the smelting industry crush the electrode paste into 5-10mm particles with a jaw crusher, which is used as a material for repairing the bottom of the furnace and used as a smelting flux. . The reason, let me talk about it slowly.

Melting flux is a mixture of various materials formulated and then heated and melted. The melting method can be heated by flame or arc, and the heating temperature is generally 1500 to 1600 degrees Celsius. During the entire heating and melting process, the carbonate in the ore is decomposed, the high-valence manganese is reduced to MnO and forms silicate with SiO2, and the SiO2 is burned. Then pour the refined flux into water at a temperature lower than 20 degrees Celsius to form the flux into particles, which is called wet method; or use compressed air to blow the molten flux into small particles, which is called dry method. The wet-processed flux should be dried at a temperature of 250 to 300 degrees Celsius, and the moisture (mass fraction) after drying should not exceed 0.1%.
