F. On the other hand, as the gas with high oxidizability introduced to pre-reduction process, it will give a lower reductibility of iron ore and as the ore come to the final process the burden of the final reduction vessel will be heavier, the refractories of it will be corroded seriously and the campaign-life of it will be shorter.
终还原排出的煤气可以供预还原使用，由于排出煤气温度较高，需要降温才能供预还原炉使用，在此过程中煤气的物理热未被利用，这是目前熔融还原工艺能源消耗普遍大于高炉工艺能源消耗的主要原因；同时排出煤气氧化度较高，影响到矿石的预还原率较低，铁浴终还原的负担较重，终还原炉渣对炉衬的侵蚀严重，影响到铁浴终还原炉的寿命。

The feature of the shaft furnace-iron bath smelter charging carbon-bearing pellets is that partial off-gas of shaft furnace is mixed with gas from smelter and then put into shaft for preheating and pre-reduction. The optimum operational parameter is at the point of prereduction degree of 52% and post-combustion degree of 32% where the coal consumption is 750kg/tone-hot metal and oxygen consumption is 420Nm〓/tone-hot metal.(5) The systematic simulation of rotary hearth furnace-iron bath smeter is firstly formulated.
4本文建立的含碳球团竖炉—铁浴工艺流程模型的特点之一是竖炉炉顶出口煤气的一部分与铁浴煤气混合后，重新进入竖炉，本文报道的对系统部分出口物流返回反应器的非序贯式流程进行的系统模拟，为今后类似问题的模拟提供了参考，本工艺的最低消耗点的操作条件是：预还原度52％，二次燃烧率32％，这时的最低煤耗为750kg／tFe（中挥发份煤VM=19％），氧耗约420Nm〓／tFe，对应于预还原度30～70％的优化组合的二次燃烧率为32～13％。

And the other is arc Process using pre-reduction pellets or high-quality industrial scrap as raw materials.
当前，主要有二种炼钢工艺，较为普遍的是以高炉铁水和废钢为原料的转炉炼钢工艺，其次是以预还原球团矿或高质量的工业废钢为原料的电弧工艺。
