郑州纺织机械厂铸工车间铜炉组工人,在学习外单位先进经验的基础上,改变地坑坩埚炉结构,制造一种简易反射式坩埚炉,取得良好的经济效果。每公斤煤可熔化2．3－2．5公斤铜,过去每公斤煤仅能熔化正．5公斤铜。普通坩埚炉的坩埚使用寿命仅15包次左右,因为坩埚埋在煤块中间,底部四周侵蚀严重,而这种炉子的坩埚置于火口位置,可以四周调换,侵蚀到周围只剩十几毫米才报废,使坩埚寿命高达65包次。
Based on the advanced experience of learning units, the copper furnace group workers of the foundry workshop in Zhengzhou Textile Machinery Factory changed the structure of the pit crucible furnace to make a simple reflection crucible furnace and achieved good economic results. 2.3-2.5 kg of copper can be melted per kilogram of coal, only past each kilogram of coal can be melted. 5 kg of copper Ordinary crucible furnace crucible life is only about 15 times the package, because the crucible buried in the middle of the coal, the bottom of the serious erosion around, and this crucible furnace placed in the crater position, you can swap around, erosion to the surrounding only a few millimeters Scrap, crucible life up to 65 packets times.
