一、负偏差轧制的经济意义所谓负偏差轧制是指充分利用产品厚度尺寸公差所允许的波动范围,将成品钢板的厚度尺寸控制在负偏差范围内,使成品钢板的厚度小于公称尺寸。 GB708—65第8条规定“钢板按理论重量交货时,比重采用7.85。”冶金部把大力推行负偏差轧制列为提高质量、提高钢的成材率、加强技术管理、降低产品成本的主要途径,对国家、企业、用户都有重要的经济意义。这样一可提高钢材成材率的重要途径;二可以降低生产成本,提高经济效益;三可以促进企业的技术进步,提高管理水平;四可以
First, the economic significance of negative deviation rolling The so-called negative deviation rolling refers to make full use of product thickness tolerances allowed by the fluctuation range, the thickness of the finished steel sheet size control within the negative deviation, the finished steel thickness less than the nominal size. GB708-65 Article 8 stipulates that “the steel plate by theoretical weight delivery, the proportion of 7.85.” Metallurgical Department to promote negative deviation as listed to improve quality, improve the rate of steel production, strengthen technical management, reduce the cost of the product Ways, on the country, business, users have important economic significance. Such an important way to improve the rate of steel into the finished product; two can reduce production costs and improve economic efficiency; three can promote the technological progress of enterprises and improve the management level; four can
