The mixing ratio of lining materials is not reasonable
炉衬材料混合配比不合理
The mixing of lining materials has fixed standard requirements, for example, the content of capacitor calcium oxide is greater than 96%, the content of magnesia lining magnesium oxide is greater than 98%, and the ratio of alumina to mullite is 71.8% and silicon oxide is 28.2%.
炉衬材料的混合有固定的制度要求，举例说明电容氧化钙成分含量大于96%，镁砂炉衬氧化镁含量大于98%，莫来石要求氧化铝71.8%，氧化硅28.2%的配比等。
If the ratio of lining materials is not correct or contains too much impurities, the bottom of the furnace will also appear the phenomenon of furnace leakage.
如果炉衬材料的配比不正确或含有的杂质过多也会出现炉底漏炉的现象。
3, the furnace lining knotting process is not in place
3、炉衬打结工艺不到位
Lining knotting process also has a direct impact on the effect of lining use, such as whether the crucible die is tilted during the knotting process, whether the knotting layer is in a plane, whether there are impurities mixed in the knotting process, and so on. If the process is not properly aligned, it will also affect the quality of the lining.
炉衬打结工艺对于炉衬使用的效果也有着直接的影响，比如打结过程中坩埚模是否有倾斜，打结层是否在一个平面，打结的时候是否有杂质混入等等工艺如果没有做到位也会影响炉衬质量。
4. There is no good lining for baking
4、没有做好炉衬烘烤
The purpose of the oven is to heat and bake the furnace lining bricks that are in standby and normal temperature state after masonry, so that the surface has a certain thickness of high temperature layer to meet the requirements of steelmaking.
烘炉的目的就是将砌筑完毕处于待用、常温状态的炉衬砖加热烘烤，使其表面具有一定厚度的高温层，达到炼钢要求。
