我国富产钛铁矿,缺少天然金红石。金红石是制造电焊条的主要涂料。在三相电弧炉内用碳粉还原钛铁矿中铁的氧化物,使二氧化钛富集成为高钛渣,经渣铁分离,再经氧化焙烧可制取人造金红石。此方法生产工艺复杂,耗电量大,产量又远远不能满足电焊条工业发展的需要。根据电炉冶炼的原理,试用固相还原法,将钛铁矿与碳粉按比例成型,装入反射炉中进行高温焙烧,还原钛铁矿,用以制造电焊条的涂料,可以代替人
China’s rich ilmenite, the lack of natural rutile. Rutile is the main coating for the manufacture of welding electrodes. In a three-phase electric arc furnace, the oxide of iron in the ilmenite is reduced with the carbon powder so that the titanium dioxide is enriched into high titanium slag, separated by slag and iron, and then made into artificial rutile by oxidation roasting. The method has the advantages of complex production technology, large power consumption, and the output can not meet the needs of the industrial development of welding electrodes. According to the principle of electric furnace smelting, the trial solid phase reduction method, the ilmenite and toner in proportion to shape, into the firing furnace for high temperature calcination, reduction of ilmenite, used to manufacture welding electrode coatings, can replace people
