优化生产组织模式 提高RH生产能力

Optimization of production process management to enhance RH productivity

RH是生产品种钢的关键工序,随着前工序铁水量的增加和后工序品种钢需求的增加。宝钢分公司第一炼钢厂的RH成为影响品种钢产能和物流的瓶颈工序。通过分析影响RH产能的因素后,从RH的生产组织原则、RH钢种铸机分配、RH分工、缩短RH处理周期、模铸钢生产组织、模铸钢与连铸匹配性等方面进行了优化,RH日均处理量提高了2.9炉,同时降低了RH非工艺处理钢的比例。

RH treatment process used to be the bottleneck of quality steel production and logistics at No. 1 Steelmaking Plant of Baosteel owing to its long treatment time. After analyzing the influencing factors on RH productivity, the principle of RH manufacturing schedule,liquid steel distribution to casters,shortening RH trestment period, ingot casting schedule and the coordination of ingot casting with continuous casting have been optimized, RH productivity has been enhanced by 2.9 heats per day.
