【摘要】：随着钢铁市场竞争的日益激烈与行业整体利润率的下滑,如何在不影响产品质量的前提下节能减耗已经成为现场技术攻关的焦点。为满足冷轧生产的需求,提高产品的竞争力,充分考虑到冷连轧机组的设备与工艺特点,在建立了一套吨钢电耗计算模型并分析了吨钢电耗影响因素的基础上,从轧制规程、乳化液流量、轧制速度的综合优化设定入手,以降低吨钢电耗为目标,同时考虑到机组最大轧制压力、最大轧制功率、打滑与热滑伤的防治、乳化液最大流量、乳化液综合成本、产能效益等因素的约束,提出了一套冷连轧过程吨钢效益综合控制技术,并将其推广应用到生产实践,在吨钢乳化液消耗没有增加、产能没有下降的前提下,吨钢电耗平均下降了7.53%,为机组创造了较大的经济效益,具有进一步推广应用价值。
[Abstract]:With the increasingly fierce competition in the steel market and the decline of the overall profit margin of the industry, how to save energy and reduce consumption without affecting the product quality has become the focus of the field technology. In order to meet the demand of cold rolling production and improve the competitiveness of the products, considering the equipment and process characteristics of the cold continuous rolling mill, a set of calculation model for the power consumption of tons of steel was established and the influencing factors of the power consumption of the steel per ton were analyzed, based on the rolling schedule. In order to reduce the power consumption of tons of steel, considering the maximum rolling pressure, the maximum rolling power, the prevention and cure of skid and hot slip, the maximum flow rate of emulsion is considered. In this paper, a set of comprehensive control technology of ton steel benefit in cold continuous rolling process is put forward, which is restricted by factors such as comprehensive cost and productivity benefit of emulsion, and it is popularized and applied to production practice. Under the premise that the consumption of emulsion does not increase and the production capacity does not decrease, The average power consumption of steel per ton has decreased by 7.53, which has created a great economic benefit for the unit and has the value of further popularization and application.
