苏联哈薩克共和国的科学家們創造了一种新的金屬熔煉法。新的熔炼法可以簡述如下。以极快的速度把热风压入同柱形的迴轉熔炼桶,形成涡流。这时把燃料和經过粉碎的熔炼材料送进涡流。熔炼材料受离心力作用,被拋向熔炼桶壁,在那里遇到迅速旋轉着的熾热的气体立刻熔化。这种迴轉熔炼爐可以使挥发性金屬的烧热、熔炼、挥发等过程同时进行。这样一来,在精炼含有多种金屬的矿石时,就可以把所有的貴重成分从矿石里提取出来。用这种方法可以从铁矿石直接炼鋼,不必 Scientists in the Soviet Union of the Kazakh Republic created a new method of metal smelting. The new melting method can be summarized as follows. To a very fast rate of hot air into the same cylindrical rotary melting smelt, the formation of eddy currents. At this moment, the fuel and the crushed smelting material are fed into the vortex. Smelting material by the centrifugal force, thrown to the melting barrel wall, where the rapid rotation of the hot gas encountered immediately melted. This rotary smelting furnace allows volatile metal smelting, melting, volatilization and other processes at the same time. In this way, all the precious components can be extracted from the ore while refining the ore containing many metals. It is not necessary to use this method to make steel directly from iron ore
