摘要
要为回收钨尘，利用钨尘灰与碳酸钠在０．１ＭＶＡ电炉内进行了回收试验，制成粗钨酸钠。结果表明，若找到合适的配料比、用电制度及冶炼时间，则可进一步降低原料消耗和生产成本。
In order to recover the tungstenic dust, sodium carbonate was added to it and smelting test was carried out in a 0. 1MVA electric arc furnace. The result shows, if proper charge ratio, power condition and smelting time can be fined, material consumption and productive cost can be further decreased.
