摘要
针对传统直喷润滑系统不能实现乳化液流量与浓度的同时在线调整,造成二次冷轧机组升降速与钢种切换过程中轧制不稳定、板厚与板形质量不佳、轧制能耗与油耗总成本较高等问题,结合二次冷轧机组的设备及工艺特点,在搭建的试验平台上完成了乳化液管路直接混合润滑系统关键设备选型,提出了一套适合于二次冷轧机组的乳化液管路直接混合润滑系统设计方案、对管路直接混合与混合箱搅拌混合乳化液特性进行了对比,并将该润滑系统应用到某钢铁企业1220二次冷轧机组的生产实践,有效提升了轧制稳定性、带钢厚度与板形质量、降低了轧制能耗与油耗总成本。
The traditional direct application system can only online adjusting the emulsion flow,but cannot online adjusting the emulsion flow and concentration simultaneously,resulting in the rolling instability,poor strip thickness and flatness quality,high rolling energy and oil consumption cost during the steel grade change,rolling acceleration and deceleration in the double cold reduction mill.Combing with the equipment and technological characteristics of the double cold reduction mill,the key equipment of the emulsion pipeline direct mixed lubrication system was optimizing selected on the developed experimental platform.Thus,the design method of the emulsion pipeline direct mixed lubrication system in the double cold reduction mill was proposed.Moreover,the emulsion properties of the mixing tank agitation and the pipeline direct mixing were compared.Then,this lubrication system was applied in a1220 double cold reduction mill,with the rolling stability,strip thickness,flatness quality effectively improved,and the rolling energy and oil consumption cost reduced.
