轧钢机上广泛使用布胶轴承,但生产每平方米的布胶板约需250～300米~2的棉布与占其总重50％的酚醛树脂,成本既高,还大量消耗稀缺的棉布与树脂,供应不能得到保证。1959年四季度起,我厂与北京市木材厂、北京林学院等单位协作,由北京市木材厂试制压缩木轴承材料,1960年三季度起在我厂试用。四年来,经过不断改进设计与加工,目前我厂全部热轧机上(515轧机,400轧机,270轧机,400轧机和450轧机),除个别的瓦肩外,已全部改用压缩木轴承,效果很好。为国家节约大量棉布、树脂;生产成本降低,其费用只有布胶的3—5％;使用寿命长:在转速较快的270轧机上也达到两个月,已接近或达到布胶轴承的正常使用寿命。
Rolling mill widely used cloth plastic bearings, but the production of cloth per square meter of plastic sheet about 250 ~ 300 m ~ 2 cotton and 50% of the total weight of phenolic resin, the cost is high, but also extensive consumption of scarce cotton and resin , The supply can not be guaranteed. In the fourth quarter of 1959, our factory cooperated with Beijing Timber Factory and Beijing Forestry College to produce compressed wood bearing materials from Beijing Timber Factory. Trial started in our factory from the third quarter of 1960. In the past four years, after continuous improvement in design and processing, all of the hot rolling mill (515 mill, 400 mill, 270 mill, 400 mill and 450 rolling mill) in our factory have all switched to compression wood bearings except for individual shingles. well. Saving a large amount of cotton cloth and resin for the country; reducing the production cost, only 3-5% of the cost of the cloth; long service life: it reaches two months on the 270 rolling mill with a faster speed, approaching or reaching the normal of the cloth bearing Service life.
