MHI(三菱重工)研制成功二种新轧机,该轧机能把不锈钢、钛钢等难轧材料轧制到厚为15μm、宽为1000mm的薄板,产品尺寸精度高达0.001mm,轧制速度为300m/min。 轧机由小直径轧辊组构成,与四辊轧机一样操作简便。如今,一般带钢轧机的操作需要熟练技术工人,但MHI新轧机操作人员不需要专门培训。 第一台新轧机在今年4月供货给日本不锈钢公司在Joetsu的Naoetsu厂。该轧机工作辊最小直径是
MHI (Mitsubishi Heavy Industries) has successfully developed two new rolling mills that can roll hard-to-roll materials such as stainless steels and titanium steels to 15-μm-thick and 1000-mm-wide sheets with product dimensions up to 0.001 mm and a rolling speed of 300 m / min. The mill consists of a small diameter roll set, which is as easy to operate as a four-roll mill. Today, the operation of a typical strip mill requires skilled workers, but MHI new mill operators do not need specialized training. The first new mill was delivered to Japan’s stainless steel company Naoetsu Plant in Joetsu in April this year. The minimum diameter of the work roll of the mill is
