目前,我国中小型及线材轧机多采用由8～10in 钢锭经φ500～650开坯机轧成50～90mm 的热轧方坯。钢坯生产消耗大、成本高、技术落后。而紧凑式连轧机是解决连铸坯与现行中、小型及线材轧机衔接较理想的设备。它是一种新型轧机,具有布置紧凑、大压下量、连续轧制等优点。用紧凑式粗轧机改造旧轧机,对提高经济效益具有重要意义。下面介绍我厂小型车间紧凑式粗轧机的改造情况,以供我国众多中小型轧机生产线技术改造参考。
At present, China’s small and medium-sized wire rod mill and more by the use of 8 ~ 10in ingot by φ500 ~ 650 open billet rolling machine 50 ~ 90mm hot-rolled billet. Billet production costly, high cost, backward technology. The compact continuous mill is to solve the continuous casting slab with the existing medium and small and wire rod mill convergence ideal equipment. It is a new mill with the advantages of compact layout, large reduction, continuous rolling and more. The use of compact rough rolling mill to transform the old rolling mill, to improve economic efficiency is of great significance. The following describes the transformation of compact mill roughing mill in our small plant, for reference for the technological transformation of many small and medium-sized mill production lines in our country.
