炼铁

The reduction thermodynamics of Na 2CrO 4 and chromium oxides in the process of sintering and ironmaking is studied,and the simulating experiments in the laboratory and industrial experiments in 600 m 3 blase furnace are carried out.

介绍了铬渣用作炼铁熔剂的基本思想，研究了烧结－炼铁工艺中Na2CrO4和铬氧化物还原的热力学，并进行了实验室模拟试验和600m3高炉的工业试验。

All these measures push the improvement of ironmaking cycle economy level and promote energy saving and reduction of consumption.

这些措施有力地推动了炼铁循环经济水平的提高，促进了炼铁的节能降耗。

Course of production development and technical advances in Jiangxi ironmaking industry passed in review in this paper.

The object of ironmaking is high quality, low loss, high yield and longevity.

如何控制高炉安全、稳定、均衡、顺行从而达到炼铁界提出的"优质、低耗、高产、长寿"的炼铁目标具有重要的生产实践价值。

The results indicate that both of that of iron and steel industry exceed that of whole industry average level.In iron and steel industry,ironmaking consumes most energy and yields most pollutants.The ironmaking's net energy consumption per ton pig iron of key iron and steel works is 704 kg,about 29.5%of which is used for sinter and cokemaking and isn't reclaimed satisfactorily after enhancing the physical and chemical character of raw material.This is one of the reasons why ironmaking system consumes so much energy.

结果表明：钢铁工业的能耗、污染物排放量远高于工业部门平均水平；在钢铁工业内部，炼铁系统的污染最严重，能耗最高。1996年全国重点钢铁企业吨铁净能耗为704 kg，其中29.5 ％用于烧结和焦化工序，且在提高原料的理化性能之后，未得到充分回收和利用，是炼铁系统能耗高的一个重要原因。
