Abstract
The invention discloses a zinc residue double-vacuum purification charging basket anti-corrosion method, and particularly discloses a zinc residue double-vacuum purification charging basket anti-corrosion method for the field of steel making. The zinc residue double-vacuum purification charging basket anti-corrosion method comprises the following step of carrying out diffusion coating treatment on a zinc residue double-vacuum purification charging basket made of a Q235 steel plate, wherein the diffusion coating treatment comprises the following steps of A, carrying out surface treatment on the inner surface of the charging basket; B, preparing a permeating material, placing the prepared permeating material into the charging basket; C, placing the charging basket into the inner tank of a double-evaporation purification furnace, then carrying out vacuumizing treatment on the inner tank of the double-evaporation purification furnace, stopping vacuumization and filling argon when the vacuum degree of the inner tank is less than 10 Pa, and stopping argon filling when the pressure of the inner tank ranges from 10<4> Pa to 1.2*10<4> Pa. The zinc residue double-vacuum purification charging basket anti-corrosion method disclosed by the invention can effectively prevent the zinc residue double-vacuum purification charging basket from being excessively fast corroded; the zinc residue double-vacuum purification charging basket anti-corrosion method can effectively solve the problem that the traditional charging basket is easy to corrode by carrying out the diffusion coating treatment on the zinc residue double-vacuum purification charging basket made of the Q235 steel plate, thereby prolonging the service life of the charging basket.
