稀有公司铝厂近期在节能降耗上又使出新举措,对电解车间出铝使用的真空包下管进行了小改造。因出铝时,真空包下管长时间在940℃的高温电解质及铝水中浸泡导致管口融化严重,长度逐渐缩短,不能够使用,造成下管的浪费。而电解车间平均每月使用3~4根下管,每根下管购进价为860元左右。为降低成本,铝厂员工根据出铝操作实际,自行制作了一节长达25 cm的接管,装在下管与上管接口处,原先长度缩短的下
Rare company aluminum plant in the recent energy-saving and consumption reduction to make new initiatives on the electrolysis plant out of aluminum vacuum tube used for a small transformation. Due to the aluminum, the vacuum tube under the tube for a long time in 940 ℃ high temperature electrolyte and aluminum immersion led to the nozzle melt serious, the length gradually reduced, can not be used, resulting in waste under the tube. The average daily use of electrolysis plant 3 to 4 under the tube, each purchase price of the next tube is about 860 yuan. In order to reduce costs, aluminum factory staff according to the actual operation of the aluminum, produced a takeover of up to 25 cm, installed in the lower tube and the upper tube interface, the original length of the lower
