摘要:
电热法制磷选用的炭质还原剂有煤炭和焦炭两种，相同条件下，炭质还原剂性能的选择决定了炉况的好坏及生产经济技术指标的高低.炭质还原剂的质量影响炉内最佳电炉熔池的形成.无烟煤化学活性差，常温下与高温下的电阻率相差2 500倍，不宜作为电热法制磷电炉的炭质还原剂.炭质还原剂的粒度15 mm时炉料电阻最大，此时液固两相间接触面积大，有利于还原反应速度加快，是黄磷生产炭质还原剂规定粒度为3~16mm的理论依据.科学合理地选择炭质还原剂，使黄磷生产在最佳工艺条件下稳定运行，能创造好的经济效益.
Abstract:
Coal and coke are main carbonaceous reductants in yellow phosphorus production using electrothermal method. At the same conditions, the selection of carbonaceous reductants affects the furnace condition and economic and technical index. The quality of carbonaceous reductants influences the best bath of electric furnace formation .Anthracite coal has poor chemical activity, in which the variation electrical resistivity amounts to 2500 times at room temperatures and high temperatures, and it should not be selected as carbonaceous reductant in yellow phosphorus production using electrothermal method. The electrical resistivity of furnace charge reaches a maximum when the particle size of carbonaceous reductant is 15 mm, in which the contacting area of solid-liquid two-phase is large, accelerating the reduction reaction velocity. We should select the carbonaceous reductants scientifically and reasonably to the ensure the yellow phosphorus production running steadily, which can create good economic benefits.
