初轧厂共有四台20/50t钳式吊车,其中除一台系国产外,其余三台均系六十年代初期从苏联引进。钳式吊车是初轧厂重要设备,它负担着均热炉装出钢锭、检修炉盖的吊装,和在必要时拨动运锭车到所需炉位等任务。它工作繁重、速度快、环境温度高,是其它一般桥式吊车所不能比拟的,因此钳式 There are a total of four 20 / 50t clamp-type cranes in the early rolling mill, of which three are all imported from the Soviet Union in the early 1960s, except for one made in China. The clamp-type crane is an important equipment for the first rolling mill. It is responsible for loading the ingot in the soaking furnace, hoisting the overhanging furnace cover and, if necessary, dialing the ingot to the required position. Its heavy workload, high speed and high ambient temperature are unmatched by other general bridge cranes. Therefore, the clamp type
