我厂采用整模涂蜡离心——振动复合工艺生产普通钢筋混凝土小口径压力管.用12.2万元投资,改建630m~2车间,增加了整模涂蜡离心——振动工艺所需设备,形成了年产20公里小口径压力管的生产线.整条生产线(除锅炉与其他车间共用外)只用15个人.投产一年多来,情况良好.现就这种制管工艺简要介绍如下:(一)整模涂蜡离心——振动复合工艺的优点.这种工艺是用无缝钢管做模子,与两半模区别叫整模.在模内喷上一定厚度的石蜡.管子带模蒸养后,蜡层熔化形成间
Our factory adopts the whole-mold wax-spinning-vibration compounding process to produce common reinforced concrete small-diameter pressure pipes. It invests 122,000 yuan to rebuild 630m~2 workshops, and adds the equipment needed for the whole-mold wax coating centrifugal-vibration process to form The production line of small-diameter pressure pipes with an annual output of 20 kilometers. The entire production line (except for boilers and other workshops) uses only 15 people. It has been in good condition since it was put into operation for more than a year. The pipe-making process is briefly introduced as follows: A) The advantages of the entire mold waxing centrifugal - vibration composite process. This process is to use seamless steel pipe as a mold, and the difference between the two molds is called the whole mold. Spray a certain thickness of paraffin in the mold. Tube with mold steaming Afterwards, the wax layer melts to form a room
