我院轧钢教研室,对“极薄带材异步轧制工艺”经过多年的试验研究,取得了可喜成果,并于今年七月初,在冶金部科技办主持下,通过了鉴定。 极薄带材异步轧制是运用轧辊的圆周速度的不同,改变金属变形条件,在轧辊直径相对较大的普通小型四辊轧机上轧制出厚度为0.005 mm的极薄带材的新工艺方法,它具有如下几个特点: 1.利用普通四辊轧机稍加改装即可轧出0.005mm以下的极薄带材,突破了普通轧制方法的辊径与轧厚比D/h<1500～2000的限制,达到了20000以上,这是带材冷轧技术上 Our rolling mill teaching and research room, after “years of experimental research on the” extremely thin strip asynchronous rolling process ", has made gratifying achievements and passed the appraisal in early July this year under the auspices of the Science and Technology Office of the Ministry of Metallurgy. Ultra-thin strip asynchronous rolling is the use of the different circumferential speed of the roll, changing the metal deformation conditions, the relatively small diameter roller mill rolling a thickness of 0.005 mm thin strip of the new process method , It has the following characteristics: 1. The use of ordinary four-roll mill slightly modified can be rolled out of 0.005mm the following ultra-thin strip, breaking the ordinary rolling method of rolling diameter and thickness ratio D / h <1500 ~ 2000 limit, reaching more than 20,000, which is cold strip technology
