杭州制氧机厂铸工车间工人,在车间党总支的领导下,活学活用毛主席的光辉哲学著作,树雄心,立壮志,于今年初,采用流态自硬砂造型、制芯生产空气透平压缩机上、下机壳等大型铸铁件获得成功。上机壳重15吨,下机壳重达38吨,为采用流态砂生产大型铸铁件,创造了经验。空气透平压缩机下机壳,铸型由六层砂箱组成,泥芯共71个,下芯配模时要用 Under the leadership of the party branch chief of the workshop, Hangzhou Oxygen Plant foundry workers, living under the leadership of Mao Zedong’s glorious philosophy, are ambitious and ambitious. At the beginning of this year, they adopted the flow modeling of self-hardening sand and the core production of air Turbine compressor, the lower case and other large cast iron success. Weighing 15 tons on the chassis, the chassis weighs 38 tons, the use of flow sand production of large castings, and created the experience. Air turbine compressor chassis, the mold consists of six sand boxes, a total of 71 mud core, the core with the mold to be used
