查询词典 sulfur black

Through analysis of variance, the best mass ratio of different coating material matching is found out: It is the best matching when the mass ratioof red clay membrane urea is 5:7,which can lengthen the eluviationing time for 11 days, reduce the nitrogen eluviationing loss by 16.12%; the amount of the clay quality has no use to lengthen the eluviationing time and the result is not obvious; when the quality ratio of urea and gypsum is 5:8,it can lengthen the eluviationing time for 8 days, reduce the nitrogen eluviationing loss by 23.86%;when the quality ratio of urea and gypsum is 5:7,it can lengthen the eluviationing time for 30 days, reduce the nitrogen eluviationing loss by 16.58% when the contrast urea N is all eluviated out ; it is the optimum matching association; When the quality ratio of the urea and the sulfur is 5:6, which is a optimum proportion ,it can l

根据对淋溶时间、经济成本等的对比，经过方差分析，找出了不同包裹材料的最佳质量比的搭配组合：红胶泥包膜尿素的质量比是5：7时最好，可以延长淋溶时间11天，减少氮素淋溶损失16.12%；粘土质量的多少对延长尿素的释放时间作用不大，效果不明显；石膏和尿素两者的最佳质量比是5：8时，可以延长淋溶时间8天，减少23.86%的氮素淋溶损失；硼砂和尿素的质量比是5：7可以延长淋溶时间30天，当对照尿素N素全部淋出时，减少16.58%的氮素淋出，是最优

This research is a new low cost method of producing abrasive grit. It is to put the iron ore concentrate, coal powder, hydrated limed and addition agent together to make coal mixed pellet in prior which is rapidly auto-reduced in high temperature and kept about 10min above 1350℃, and then furnace cooled. The 2CaO·SiO2 of slag phase change、volume increase and natural bloom in reduction process. Finally we obtain no-slag abrasive grit through screen separation , in which the iron yield can be above 90%,the sulfur content can be below 0.05% and carbon content is lower than 4.0%.

本研究是一种全新的低成本生产铁粒的方法，它是将铁精粉、煤粉、消石灰和添加剂预先制成球团，在高温下迅速加热还原，在1350℃以上保温10分钟后随炉冷却，渣相中2CaO·SiO2在冷却过程中发生相变，体积膨胀而自然粉化，通过筛分便可以得到不含炉渣的铁颗粒，铁的收得率在90%以上、S≤0.05%、C在4.0%左右。
