摘 要:
实行负偏差轧制，是热轧带肋钢筋的生产实现经济效益最大化的一个重要手段。负偏差率的波动，会对钢筋强度造成影响。本文针对负偏差与强度的关系进行了分析，采取优化孔型、规范调整、成品在线称重等措施，使各规格螺纹钢负差均衡率提高了4．8％-30.8％。因负差均衡率的提高，负差率总体平均水平由4．02％，提高到4．25％。[著者文摘]

Abstract:
Minus - deviation rolling is an important means to realize the maximization of economic benefit in the production of the hot rolled fibbed steel bars. But fluctuation of the minus - deviation ratio has the great effect on strength of the bars. The article analyses the relationship of the minus - deviation and the intensity, some measures, such as optimization pass, normative regulation, weighing online and so on, have been adopt to enhance the minus -deviation equilibrium ratio to 4.8 - 30.8 percent. So the general average level of the minus - deviation ratio has been increased from 4.02 percent to 4.25 percent.[著者文摘]
Key words:
