我厂铸造车间从去年开始生产绞肉机,铸件材料为HT20—40。为了防止绞肉机铸件长期使用后生锈,需要对壳体、螺旋、手把三处铸铁件进行热镀锡。我们根据民间可以用锡粘补铁锅的原理进行了多次的摸索。基本上掌握了铸铁件热镀锡的方法,且工序简单,成本低,还省掉了预先镀铁的工艺。为民品上马铺平了道路。 My factory foundry workshop began producing meat grinder last year, the casting material is HT20-40. In order to prevent the meat grinder castings rust after long-term use, the need for casing, spiral, handle three cast iron parts for hot-tinning. According to the principle that we can use tin to stick up the wok for many times, we have been exploring. Basically mastered the method of hot-cast iron castings, and the process is simple, low cost, but also eliminates the pre-plating process. Paved the way for the sale of civilian products.
