1978年,ASEA—NTBY 钢铁公司投资450万瑞典克朗订购了一套不锈钢粉末生产设备和一台 Quintus 型钢粉制品等压压力机。新工厂约在两年后建成,其年产量为4500吨钢管。ASEA—NYBY 法的工艺过程如图昕示:1.原料处理:把经过仔细分类和定级的碎料放在感应炉内熔化。分析熔融金属并添加合金剂以使其成分准确。2.雾化:将熔融金属注入雾化室顶
In 1978, ASEA-NTBY Steel invested 4.5 million Swedish kronor to order a set of stainless steel powder production equipment and a Quintus steel products such as pressure presses. The new plant was completed in about two years, its annual output of 4,500 tons of steel. ASEA-NYBY process as shown in Figure Xin shows: 1. Raw material handling: carefully classified and graded pieces of material placed in the induction furnace melting. Analyze the molten metal and add the alloy to make its composition accurate. 2. Atomization: Molten metal is injected into the top of the chamber
