摘要
铝锭铸造机组是铝冶炼企业形成最终产品的重要工艺设备,设备的平稳运行和充分发挥机械效率,是保障日常生产需求与最终产品外观质量的基本条件。本文针对连城分公司200 kA铸造车间20 kg铝锭连续铸造机组循环水设施和铝锭连续铸造机组主体部分存在的问题和局部设计改造进行了论述与经济分析。通过对ATZJ2-20/16-Ⅱ.20 kg铝锭铸造机组的进一步优化改进,使日常生产中铝锭脱模率由设备改造前的20%左右,提升到了设备改造后的98%以上,生产过程中铝锭脱模率低、产品外观质量有缺陷的"瓶颈"问题得到了解决,在人力、财力、物力、电力方面节省了开支,同时企业经过工艺设备的优化改进,提高了水资源的再循环利用,进一步完善了企业节能减排工作目标,降低了铝锭的生产成本。
Aluminum ingot casting machine is the main technological equipment for final product of aluminum smelters. Sta- ble performance and fully exertion of mechanical efficiency is essential for daily production and final product appearance quality. This paper mainly discussed main problems in aluminum ingot machines for 20kg products, in Liancheng branch of China Aluminum Corporation, and also the economic benefit of its partial modification. After modification, the daily ingot strip ratio of ATZJ2-20/16-11.20 k9 ingot machine improved greatly from 20% up to more than 98%, and tile bottleneck in low ingot stripped ratio and defects in appearance quality is solved, the cost in labor force, material and power is reduced, water resource recycling and energy-saving and environment protection are improved, and also the cost for aluminum ingot＇ s production is lowered.
