北京市机电院和北京玛钢厂共同设计和研制了一吨工频无芯塞杆式底注保温浇包,已在北京玛钢厂生产运行半年多,取得了良好的效果,并于1981年9月16日通过了鉴定。这种浇包是目前在国内外均没有的一种新型保温浇注设备。它生产效率高,每个小时可浇注450型,能满足各种挤压生产线的要求;能较严格的控制浇注温度,显著的降低铸件废品率,避免低(?)铁水的浪费;设
Beijing Institute of Electrical and Mechanical Services and Beijing Masteel jointly designed and developed a ton of frequency coreless rod-type underfloor insulation ladle, has been operating in Beijing Masteel steel production more than six months, and achieved good results, and in September 1981 On the 16th passed the appraisal. This ladle is currently no new type of insulation at home and abroad pouring equipment. Its high production efficiency, pouring 450 per hour, can meet the requirements of a variety of extrusion lines; can more strictly control the pouring temperature, significantly reduce the casting scrap rate, to avoid low (?) Hot metal waste;
