小型冷轧机(图1)轧辊轴承,目前绝大多数采用铜合金材料,由于受到的轧制力较大且带有冲击性,因此,铜轴承寿命短、事故多、检修周期短。为此,我局属下单位采用了SF-2型复合材料代替铜合金轴承应用在小型冷轧机上,一年多来试验实践证明,SF-2型复合材料具有寿命长、强度高等一系列优点,应用结果是令人满意的。现把应用情况介绍如下。 Small cold rolling mill (Figure 1) roller bearings, the vast majority of the current copper alloy material, due to the rolling force is greater and with impact, therefore, copper bearing life is short, the accident and maintenance cycle is short. For this reason, our bureau adopted SF-2 composite material instead of copper alloy bearing to be applied to small cold rolling mill. Over the past year, experimental practice has proved that SF-2 composite material has a series of advantages of long life and high strength , The application result is satisfactory. The application is introduced below.
