近年来,在冶金工业上,由于成功的应用了制取金属和加工金属的新方法,因而明显的出现了一种用气瓶工艺工序或将其中的一些排除出去的方法以减少操作数目的倾向。直接从矿石中制取金属,在很短的时间内将矿石加工成生铁的方法已成功的推行。无锭轧制的应用,例如,直接由液体金属连续成型的毛坯制件或型材,用粉末冶金法制造另件日益增多。在冶金生产联动线的尽头,组织也就改
In recent years, in the metallurgical industry, due to the successful application of new methods for the preparation of metals and metals, there has clearly been a tendency to reduce the number of operations by using a gas cylinder process or eliminating some of them . The method of directly producing the metal from the ore and processing the ore into the pig iron in a very short time has been successfully implemented. Applications for ingot rolling, for example, for blanks or profiles that are continuously formed from liquid metal directly, increase the number of parts made by powder metallurgy. At the end of the metallurgical production linkage line, the organization will change
