国内焊锡生产的厂家很多,其生产工艺与原料各不相同。用精锡兑精铅生产焊锡是最简单的办法。但由于精锡生产过程复杂,成本高、价格贵,因此,如何从含铅、锡物料中直接生产焊锡,特别是高质量焊锡是各企业共同关心和研究的课题。目前,国内云锡一冶和柳州冶炼厂处理锡精矿和烟尘,利用原料中的铅在锡精炼过程中产出部分焊锡,即在粗锡电热结晶过程中除得部分精锡外,产出部分粗焊锡(含Sn66％),经焊锡锅精炼并调整成分后作
Domestic solder production of many manufacturers, their production processes and raw materials vary. It is the easiest way to produce solder with fine tin against fine lead. However, the production process of refined tin is complicated, costly and expensive. Therefore, how to produce solder directly from lead-containing and tin-containing materials, especially high-quality solder, is a topic of common concern and research by all enterprises. At present, the domestic Yunxi a Metallurgical and Liuzhou smelter tin concentrate and soot, the use of lead in the tin refining process to produce part of the solder, that is, in the crude tin electrothermal crystallization in addition to part of the refined tin, the output Part of the crude solder (including Sn66%), refined by the solder pot and adjust the composition after making
