苏联某特殊钢厂建设了一个半工业性的自耗电渣炼钢炉。在这炉子上先后冶炼了ШХ-15;ШХ15ГС;Р-18;ЭИ654;1×18Н9Т;Х17Н2等高级合金钢。其结果证明,这种方法极其优越。此法的基本原理之一,就是,充分利用炉渣进行洗滌。根据在铸件和锻材上取样,进行研究的结果证明,它有以下优点: (1)这种方法冶炼的钢与普通方法冶炼的钢其显著不同处就在于;a其组织极为致密,b没有缩孔和偏折的存在,c钢锭表面很光滑,在锻制以前不需要任何的精整和加工。 (2)用这种方法生产的钢比普通钢在制钢管穿孔或锻制时,俱有极高的塑性。 (3)这样的钢锻制成轧制的成品,组织极致密,没有发现任何
A special steel mill in the Soviet Union built a semi-industrial consumable ESR steelmaking furnace. In this stove has smelted ШХ-15; ШХ15ГС; Р-18; ЭИ654; 1 × 18Н9Т; Х17Н2 and other high alloy steel. The results show that this method is extremely superior. One of the basic principles of this method is to make full use of the slag for washing. The results of studies conducted on samples of castings and forgings show that they have the following advantages: (1) Steel smelted by this method is significantly different from steel smelted by conventional methods; a is extremely dense and b has no The existence of shrinkage and deflection, c ingot surface is very smooth, no need for any finishing and machining before forging. (2) The steel produced in this way has a very high degree of plasticity compared with ordinary steel when it is made into steel pipes for piercing or forging. (3) This steel forging made of rolled products, the organization very dense, did not find any
