铸铁切屑压块工艺目前,铸铁屑大多作为废料,如果将这些铁屑压成块,就可以直接作为回炉铁回炉,这样不仅减少了中间环节,而且还节约了能源。笔者经过反复试验,找到了铸铁屑压块的简单工艺。 1.铸铁屑压块的基本原理铸铁屑如不在其中加粘结剂一般是难于压制成形的。经过多种材料试验,水玻璃作粘结剂不仅粘结性好,而且又不影响铸件的质量。水玻璃是青灰色或无色半透明的粘稠液体,其化学成分是硅酸钠的水溶液(Na_2O.mSiO_2+H_2O),其
Cast iron chip briquetting process At present, most of cast iron scrap as waste, if these iron chips pressed into blocks, you can directly as a return iron back to the furnace, so that not only reduces the intermediate links, but also saves energy. After repeated experiments, I found a simple process of casting iron filings. 1. The basic principle of cast iron briquette Cast iron scrap, if not in the binder is generally difficult to suppress forming. After a variety of materials testing, water glass as a binder not only good adhesion, but also does not affect the quality of the castings. Water glass is gray or colorless and translucent viscous liquid, its chemical composition is sodium silicate aqueous solution (Na_2O.mSiO_2 + H_2O), which
