还原铁粉是粉未冶金铁基材料和制品的主要原料,也是焊接工业重要的原料之一。据报道,1977年日本焊接用铁粉消耗量近3万吨,占日本铁粉消耗量的42％。瑞典霍根纳斯铁粉公司生产的还原铁粉30％用于焊接。近年来,我国焊接工业也开展了在电焊条药皮中添加铁粉,生产铁粉焊条的工作。为适应焊接业对焊接铁粉的需求,我厂以轧钢铁磷为原料,采用固体碳还原法生产适于焊接业用的还原铁粉(以下简称焊接铁粉)。其牌号有:WHF—D315,WHF—D335,WHF—D350,WHF—D370,WHY—D250。
Reduced iron powder is the main raw material for powder metallurgy iron-based materials and products, but also one of the important raw materials for the welding industry. It is reported that Japan’s welding iron powder consumption in 1977 nearly 30,000 tons, accounting for 42% of Japan’s iron consumption. 30% of the reduced iron powder produced by Hoganas Iron and Steel Sweden is used for welding. In recent years, China’s welding industry has also carried out the work of adding iron powder in the electrode coating to produce iron powder electrode. In order to meet the welding industry on the demand for welding iron powder, I plant rolling iron and phosphorus as raw material, the use of solid carbon reduction for the production of welding industry, reducing iron (hereinafter referred to as welding iron). The grades are: WHF-D315, WHF-D335, WHF-D350, WHF-D370, WHY-D250.
