Deslagging agent for lead regeneration and preparation method thereof
The invention discloses a slag remover for lead regeneration and a preparation method thereof, and belongs to the technical field of lead alloy production, the slag remover comprises the following components: a modified reducing agent, modified expanded perlite, acyl metal powder, a combustion improver, industrial salt and borax; the main component of the modified reducing agent is nanoscale iron powder, and polyethyleneimine and guar gum are used for modifying the nanoscale iron powder; the modified expanded perlite is modified by using stearic acid; the acyl metal powder is prepared by complexing a mixed metal simple substance with CO in advance to obtain a carbonyl metal compound, and then mixing the carbonyl metal compound with other components of the slag remover for secondary lead to prepare a product, namely the slag remover for secondary lead; according to the slag remover for the secondary lead, the defect that in the prior art, single perlite is adopted as the slag remover for the secondary lead, and the performance is not stable can be overcome, all the prepared components are organically complexed to form a whole, and therefore the slag tapping strength of slag is improved.
本发明公开了一种铅再生用除渣剂及其制备方法，属于铅合金生产技术领域，本发明包括以下组分：改性还原剂、改性膨胀珍珠岩、酰基金属粉末、助燃剂、工业盐和硼砂；改性还原剂主要成分是纳米级铁粉，聚乙烯亚胺和瓜尔胶对纳米级铁粉进行改性；改性膨胀珍珠岩采用硬脂酸对其进行改性；酰基金属粉末则是将混合金属单质预先以CO络合，得到羰基金属化合物，再将羰基金属化合物和再生铅用除渣剂的其他组分混合，制备得到产品再生铅用除渣剂；本发明制备的再生铅用除渣剂可以改善现有技术中采用单一珍珠岩作为再生铅用除渣剂性能并不稳定的缺陷，且制备的各组分通过有机络合，形成整体，从而提高熔渣的出渣强度。
