铬铁合金炉 chrome ferro alloy furnace

铬铁合金炉 铬铁合金电炉炉衬主要存在镁质，碳质， 碳砖炉衬的主要问题是，cr+在高温（1450°+）下属于强氧化剂，cr+与c 剧烈发生反应，生产CR7C3 或者 CR3C2 , CR23C6 和 CO ，并由于温差等原因容易在炉内局部结壳，形成CO 聚集 。 镁质炉衬，由于镁质材料自身在冷热温度变化下，热稳定以及体积变化等原因，特别是部分区域在出钢前后温差浮动大的情况，容易出现局部脱落等现象，加之铬铁如果酸性比例过高，在高温下，容易与镁质耐材发生反应， 生成MGO.SIO2 ，CAO.MGO.SIO2 . Chrome ferro alloy electric furnace lining mainly exists magnesium, carbon base , The main problem of carbon brick furnace lining is that cr + belongs to a strong oxidant at high temperature (1450° +), and cr + reacts violently with c, producing CR7C3 or CR3C2, CR23C6 and CO, and it is easy to shell locally in the furnace due to temperature difference and other reasons, forming CO aggregation. Magnesium furnace lining, due to the magnesium material itself under the cold and cold temperature changes, thermal stability and volume change, especially parts of the large temperature difference before and after the steel floating, prone to local off phenomenon, combined with ferrochromium if acid ratio is too high, at high temperature, easy to react with magnesium resistance, generate MGO.SIO2, CAO.MGO.SIO2.
