过去水泥管的钢筋骨架全部由人工绑扎,按φ40的压力管来说,一个钢筋员架就有6816个接点,用人工绑扎,劳动强度大,工效低而且还浪费铅丝。针对这种情况,西安水泥制管厂经过反复的试验,成功地运用了可控硅自动选点滚焊,给国家节约了大量钢材,节省了人力、工效提高了3.5—4倍,同时焊点质量牢固可靠。使水泥管的生产大大地向前推进了一步。 In the past, the reinforcing steel skeleton of the cement pipe was all manually bound. According to the pressure pipe of φ40, there were 6,816 joints of a steel reinforcing member rack, which was labor-intensive, labor-intensive and wastes the lead wire. In response to this situation, Xi’an cement pipe plant after repeated tests, the successful use of SCR automatic point seam welding, the country saved a lot of steel, saving manpower, work efficiency increased by 3.5-4 times, while the solder joints Quality is solid and reliable So that the production of cement pipe to take a big step forward.
