高炉使用含锌球团矿会直接影响高炉冶炼的顺行,甚至造成高炉结瘤。本文介绍了杭钢球团矿氯化焙烧除锌试验。试验结果表明:还原氯化焙烧除锌率高达95%。而氧化氯化焙烧除锌率只有45%以下,文中还提出要推广这项试验成果还需解决氯化剂对金属设备和管道的腐蚀问题。
Blast furnace using zinc pellets will directly affect the smooth blast furnace smelting, and even cause nodules blast furnace. This paper introduces the experiment of chlorination and roasting of Hangzhou Iron and Steel Group pellets. The experimental results show that the reduction and chlorination roasting zinc removal rate up to 95%. The oxidation and chlorination roasting zinc removal rate of only 45%, the paper also proposed to promote the test results also need to solve the corrosion of chlorinated metal equipment and pipelines.
