Problems solved by technology

[0008] Although some of the above-mentioned patents relate to the slag removal agent for alloy smelting, the name of which is "refining slag removal agent for zinc-based alloy smelting and its preparation method", the invention patent with the patent number CN201610720460.0 also specifically discloses the slag removal agent In the formula, sodium nitrate, sodium chloride, potassium chloride, calcium fluoride, sodium sulfate and charcoal powder related to the present invention are mentioned in the formula, but through careful reading, it is found that these patents do not involve the deslagging of lead alloys and because the smelting temperature of lead alloys is lower than that of these metal alloys, it is not possible to use these slag removers directly for the slag removal of lead alloys, so the slag removers of lead alloys need to be further studied

Abstract

A slag remover for lead alloy smelting, comprising sodium nitrate and charcoal powder; the slag remover at least also includes potassium permanganate and / or pyrite powder, through potassium permanganate and / or pyrite powder Mix with sodium nitrate, charcoal powder, and other slag remover components to form a lead alloy slag remover; through the potassium permanganate component, it can decompose at the melting point of lead to release oxygen and oxidize charcoal with a lower ignition point , emit a large amount of heat, so that the temperature of the flux increases rapidly, reaches the decomposition temperature of sodium nitrate, further decomposes sodium nitrate, releases oxygen and oxidizes charcoal powder, generates a large amount of heat, further increases the temperature of slag, and promotes slag Separated from the lead liquid; by adding pyrite powder, the harmful elements of copper can be further removed during the smelting process.

Description

technical field [0001] The invention relates to an auxiliary agent for smelting operations and a preparation method thereof, in particular to a slag remover for lead alloy smelting and a preparation method thereof, which is mainly used for removal in smelting processing of lead alloy smelting. It belongs to the technical field of mechanical equipment auxiliary operation equipment. Background technique [0002] Due to the low temperature of lead alloy smelting, some scum will be produced on the surface during the smelting process. Due to the low temperature, the scum on the surface of the lead liquid will hold a large amount of lead liquid, thus affecting the quality of the lead alloy. In order to avoid the influence of scum, a certain amount of lead slag remover will be put in to remove slag during lead alloy smelting. The general lead slag removal agent is to add a certain amount of sodium nitrate when the lead alloy is smelted; when sodium nitrate is added to the lead liq...
