| description | The invention discloses a preparation method of high-quality arsenic-brass bars, which includes the following steps of 1), feeding arsenic-brass raw materials into a power-frequency brass melting furnace, raising temperature of the brass melting furnace unit the raw materials are melted into brass melt; 2), lowering voltage of the power-frequency brass melting furnace to be 180V, adding and melting lead which is 0.2-0.3wt% of the arsenic-brass raw materials, and adding and melting zinc ingots which is 3-5wt% of the arsenic-brass raw materials; 3), pressing Cu-As intermediate alloy to the bottom of the power-frequency brass melting furnace and stirring uniformly; 4), injecting brass refining deslagging agent which is 0.1-0.2wt% of the arsenic-brass raw materials into the brass melt, stirring continuously and refining for 12minutes to 15minutes; 5) refining and removing slag and ash; 6) refining and regulating components; 7) draining the brass melt in the power-frequency brass melting furnace into a heat insula |
