水口山矿务局第六冶炼厂的捏合机内有一种外径190毫米、内径100毫米、长300～370毫米的喇叭口管道,原用镍铬钛不锈钢板制作,使用到几个工班就需更换,严重影响生产。工人们遵照毛主席“要进一步节约闹革命”的指示,以辉绿岩粉加环氧树脂和石棉绒为原料,用捣固方法制成了辉绿岩异形管,代替了不锈钢管。通过实践,效果良好,没有出现变形和腐蚀现象。为正常生产提供了良好条件。 Shuikoushan Mining Bureau No. 6 Smelter Kneading Machine has a 190 mm OD, 100 mm inner diameter, length 300 ~ 370 mm bell mouth pipe, the original use of nickel-chromium-titanium stainless steel plate, the use of several classes to work Need to be replaced, seriously affecting the production. Workers follow Chairman Mao’s “instructions for further saving the revolution”, using diabase powder plus epoxy resin and asbestos as a raw material, and using tamping to make a diabase shaped tube instead of a stainless steel tube. Through practice, the effect is good, there is no deformation and corrosion. For normal production provides a good condition.
