last stage

3 BF came into the end-stage production,by adoption of beneficiated burden、reasonable charging system、increasing blast temperature、furnace maintenance、scheduled gunning and so on,it not only kept BF long-term stability and improves every economic indicator,but also made a historical breakthrough in many marks at the beginning of 2006.

首钢3号高炉进入末期生产以来,通过采取精料、合理装料制度、提高风温、维护炉体、定期喷补等措施,不仅使高炉长期顺行稳定、各项经济指标不断改善,且2006年初多项指标实现了历史性的突破。

Optimization of operating conditions brought the catalyst into good performance at the end-of-run of period.

通过优化工艺条件,严控进料质量、改造循环氢压缩机油系统、调整二甲苯塔操作等措施,使催化剂在运行末期,也能发挥出良好的催化性能,并延长催化剂使用寿命;提高了催化剂处理C10芳烃的能力,降低重芳烃产率,提高经济效益。
