(54) СПОСОБ ОЧИСТКИ ЦИНКА И ЦИНКОВЫХ (54) METHOD FOR CLEANING ZINC AND ZINC
1one
Изобретение относитс к металлургии цветных металлов, в частности к разработке технологии глубокой очистки цинка и цинковь: : сплавов от примеси свинца.The invention relates to the metallurgy of non-ferrous metals, in particular to the development of technology for the deep purification of zinc and zinc:: alloys from lead impurities.
Известен способ очистки цинка и цинковых сплавов от примеси свинца , включающий обработку расплава рафинирую:иими присадками, перемешивание расплава, охлаждение его, отделение свинецсодерх ацих соединении , нагрев и разливку расплава 1.A known method of purification of zinc and zinc alloys from lead impurities, including refining the melt processing: with their additives, stirring the melt, cooling it, separating the lead from the metal, heating and pouring the melt 1.
Недостатком известного способа вл етс использование рафинирующих присадок с более высокой по сравнению с цинком температурой плавлени и невысока - степень очистки расплава от свинца.The disadvantage of this method is the use of refining additives with a higher melting point compared to zinc and a low degree of melt purification from lead.
Целью изобретени вл этс повышение глубины очистки расплава до содерхсани свинца не более 0,003% и экономичности процесса.The aim of the invention is to increase the depth of the melt cleaning to a lead content of not more than 0.003% and the efficiency of the process.
Поставленна цель достигаетс тем, что в качестве рафинирующей присадки используют таллий, который ввоСПЛАВОВThe goal is achieved by the use of thallium as a refining additive.
д т при температуре расплава на 20-40 0 Biime температуры его плавлени .d t at the melt temperature of 20-40 ° Biime its melting point.
Способ осуществл етс следующимThe method is as follows.
образом.in a way.
В расплав, нагретый до температуры на 20-40-С превыиающий температуру его плавлени , ввод т таллии в ко10 личестве, превышающем в 1-4 раза содержание свинца. После ввода талли расплав охлаждают со скоростью 60вО С в час до температуры начала . кристаллизации, вывод т свинецсодерхсащие продукты, затем нагревают . The melt heated to a temperature of 20-40 ° C, which exceeds its melting temperature, is injected with thallium in a quantity exceeding 1-4 times the lead content. After entering the thallium, the melt is cooled at a rate of 60 ° C per hour to a starting temperature. crystallization, lead-containing products are removed, then heated.
15 до температуры разливкии разливают.15 to pouring and pouring.
Рвзультатьг-испытаний способа очистки на примере и сплава цинка с,О,3-0,7 процента алюмини представлены в таблице, из данных кото20 рой следует, что введение талли , осуществленное при соблюдении указанных температур расплава и скорости охлаждени , обеспечивает глубокую очистку цинка и цинковы;: сплавов To test the cleaning method using an example and a zinc alloy with, O, 3-0.7 percent of aluminum are presented in the table, from which it follows that the introduction of thallium, carried out at the indicated melt temperatures and cooling rates, provides deep cleaning of zinc and zinc ;: alloys
25 от свинца.25 from the lead.
