在许多机器制造厂中,当生产青铜铸件和铝铸件时,采用“мечта”或“зепенский”型的熔炉作为熔化设备.在生产规模不大时,在这种炉子交互熔炼青铜和铝合金.熔炉熔炼青铜以前,必须仔细清除残留的铝.熔炉用熔化冲洗的办法推行清洗,因此作为冲洗用的青铜,严重的夹杂着铝的成分,不能继续用来重熔.锡青铜中铝的含量,ГОСТ中 In many machine builders, “мечта” or “зепенский” type melting furnaces are used as melting equipment for the production of bronze castings and aluminum castings. The furnaces are used to interactively melt bronze and aluminum alloys when the production scale is small. The remaining aluminum must be carefully removed before the bronze is melted. The furnace is cleaned by means of fusing and rinsing, and therefore the bronze, which is a rinse, is heavily mixed with aluminum and can not be remelted for further reflow. The content of aluminum in the tin bronze, ГОСТ in
