长城铝业公司在混联法生产氧化中烧结法比例由原来的30％提高到近32％,其大型主体设备脱硅机不仅是平衡系统整体液量与确保液体顺利通过的关键装备,而且还是汽耗“大户”,成为内部挖潜、节能降耗的主要对象。这可从三方面下手:一是提高操作技术水平与加强管理;二是采用适合本工艺特点的先进设备;三是改进现有的工艺流程。我们根据公司氧化铝厂的特点,提出了改进现有工艺的措施,即将种分母液由前加改为后加。生产实践证明,经过这种改进,取得了较好的效
Great Wall aluminum company in the hybrid method of production of oxide sintering increased from the original 30% to nearly 32%, and its large main equipment, silicon removal machine is not only to balance the overall system of liquid and ensure that the liquid passed the key equipment, but also Gas consumption, “big”, become the internal potential, energy saving the main target. This can start from three aspects: First, improve the level of operational skills and strengthen management; second is the use of advanced technology for the characteristics of the process equipment; Third, improve the existing process. According to the characteristics of the company alumina plant, we put forward measures to improve the existing process, that is, the mother liquor from the former plus to post-plus. Production practice has proved that, after this improvement, achieved good results
