用铁模铸造铸件在我国已有近千年的历史,据最近我厂派人至山西阳城等地调查结果,旧犁、犁镜、犁铧都用铁模铸造。铸成品很耐磨,不粘土,销路极广。用铁模铸造不但节省动力,又可提高产量,而月铸件不必清砂、表面光洁、可减少剔磨、规格一致、互换性高,因此很适宜于大量生产。河南农具厂用铁模铸造水车牙轮,西北农具厂用铁模大量铸造5寸犁铧,都曾收到很大的效果。
Cast iron casting with iron mold in our country for nearly a thousand years of history, according to recent plant I sent to Shanxi and other places Yangcheng survey results, the old plow, plowshare, plowshare with iron mold casting. Castings are very wear-resistant, non-clay, a very wide market. Iron mold casting not only saves power, but also increase production, and the month castings do not have sand, smooth surface, can reduce the ticking, the same specifications, high interchangeability, it is suitable for mass production. Henan farm tools factory with iron mold casting waterwheel, Northwest farm tools factory with a large number of iron mold 5-inch plowshare, have received great results.
