南京轧钢厂是我省采用短应力轧机较早厂家之一。该厂一方面购进国内先进短应力线轧机,一方面利用短应力线轧机投资省、见效快、提高精度(提高成材率1％以上)、质量稳定、改善工艺条件等优点,在原有旧轧机牌坊的基础上,改造成K_7,K_8,K_9,K_(10)高刚度有牌坊短应力轧机,这种轧机除具有上述优点外,还具有支撑稳定、不易产生偏载的优 Nanjing rolling mill is one of the earlier manufacturers of short-stress mill in our province. On the one hand, the factory buys domestic advanced short-stress line rolling mills. On the one hand, it takes advantage of short-stress line rolling mills to invest in provinces, quick results, improve precision (improve finished product rate of more than 1%), stable quality and improve process conditions. On the basis of the arch bridge, it is transformed into a high-rigidity short arch mill with K_7, K_8, K_9 and K_10 high rigidity. In addition to the advantages mentioned above, this kind of rolling mill also has the advantages of stable support and easy occurrence of partial load
