改进生产工艺提高石灰氮的含氮量

Improvement of Production Process to Raise Nitrogen Content in Lime Nitrogen

分析了转炉法生产石灰氮中影响石灰氮含氮量的原因,通过合理掺用催化剂、调整炉料细度、改造原料配料系统等方法,优化了生产工艺条件,稳定了炉料配比以及炉料的发气量,提高了石灰氮的含氮量,氮的质量分数稳定在22.3%以上,并降低了消耗。

Reasons affecting nitrogen content of lime nitrogen, which is produced by converter process is analyzed. Production process is optimized by reasonable catalyst blending, feed distribution system innovation and so on, charge composition and gas-generating amount is stabilized, nitrogen content of lime nitrogen is raised, mass part of nitrogen is stably over 22.3%, and consumption is lowered.
