宝钢股份公司一炼钢厂起重机起重能力强,吨位大,载重能力一般在200吨以上;其工作负荷大,四班三岗制运转,长期处于24小时工作状态;起重物具有较大的危险性,如盛装高温钢水、铁水的钢包、铁包,及中间包、冷轧钢卷等。一但发生钢水、铁水等起重物倾翻、坠落等事故后果不堪设想,所以必须加强起重机的在役检测。一炼钢厂起重设备均从日本进口,由于服役时间较长,因而对起重机的在役定期检测尤为重要。在起重机的定期检修检测中,加载技术应用较为广泛。 Baosteel Co., Ltd., a steel mills cranes lifting capacity, large tonnage, load capacity is generally more than 200 tons; its workload, four shifts three-gang system, long-term in a 24-hour working condition; Lifting has a larger Dangerous, such as containing high-temperature molten steel, hot metal ladle, iron package, and tundish, cold-rolled steel coils. However, the occurrence of molten steel, hot metal and other lifting objects tipping over, crashes and other consequences of the accident can not be imagined, it is necessary to strengthen the crane in service testing. A steel mill lifting equipment are imported from Japan, due to longer service life, and therefore the regular inspection of the crane in service is particularly important. In the regular maintenance inspection crane, loading technology is more widely used.
