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

The invention discloses a deslagging agent for lead alloy smelting. The deslagging agent comprises sodium nitrate and wood charcoal powder; the deslagging agent at least also comprises potassium permanganate and / or pyritic ash; the deslagging agent for lead alloys is formed by mixing the potassium permanganate and / or the pyritic ash with the sodium nitrate, wood charcoal powder and other deslagging agent components; through the potassium permanganate component, oxygen can be decomposed at a temperature of a melting point of lead and oxidation reaction on the oxygen and the wood charcoal is carried out, and a large amount of heat is produced to ensure that a temperature of a melting agent is quickly raised to reach a decomposition temperature of the sodium nitrate, and the sodium nitrate isfurther decomposed and the oxygen is released, and then oxidation reaction on the oxygen and the wood charcoal is carried out, so that a large amount of heat is produced, a slag temperature is further raised, and separation of slag and lead liquid is promoted; by adding the pyritic ash, copper harmful elements can be further removed in a 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...
