随着钙镁磷肥的迅速发展,附产了大量的高磷镍铁,为了开展综合利用,探讨回收镍之新途径而提出了高磷镍铁中提炼镍铁合金的工艺流程。在上级党委的正确领导下,经过试验,已炼出合乎要求的镍铁合金。转炉吹炼工艺要求对镍铁合金中含镍量之测定必须快速准确。镍的现有测定方法尚不够理想和快速。有的操作繁复,费时冗长,有的则未考虑钴、铜
With the rapid development of calcium magnesium phosphate, a large amount of high-phosphorus ferronickel was produced. In order to carry out comprehensive utilization and explore new ways to recover nickel, a technological process of refining ferronickel in high-phosphorus ferronickel was proposed. Under the correct leadership of the superior party committee, after trial, has been refined to meet the requirements of nickel-iron alloy. Converter blowing process requires nickel-iron alloy in the determination of nickel content must be fast and accurate. Existing methods for the determination of nickel are not ideal and fast. Some complicated operation, time-consuming and lengthy, while others did not consider cobalt and copper
