错误的做法：在支撑砖和坩埚之间留下的空隙太小，坩埚膨胀受阻会裂开。
Wrong practice：The space left between the support brick and the crucible is too small, the crucible expansion will be blocked will crack.
正确的做法：在支撑砖和坩埚之间插入小木片，木片会燃烧掉从而留下足够的空隙。
Right practice：Insert a small piece of wood between the support brick and the crucible, and the wood burns away to leave enough clearance.
错误的做法：炉子顶部没有完全密封，坩埚顶部容易受到氧气氧化，从而产生竖直裂纹。
Wrong practice：The top of the furnace is not completely sealed, and the top of the crucible is susceptible to oxygen oxidation, resulting in a vertical crack.
正确的做法：用保温棉把炉沿密封
Right practice：Use heat insulation cotton to seal the furnace along.
一、安装坩埚前，先检查炉膛内部：炉壁和炉底应该是完好无损，干燥，没有金属或炉渣附着。如果炉壁或炉底附着水泥或炉渣，要进行清理。否则火焰的前进会受到阻碍而使火焰方向发生偏转，从而造成坩埚局部受热过度，在坩埚壁上发生氧化或产生小洞。
First, before the crucible is installed, the inside of the furnace must be checked. The furnace wall and the bottom should be intact, must be dry, no metal or slag adhesion. It must be cleaned up If the furnace wall or bottom adhesion of cement or slag. Otherwise, the advance of the flame will be hindered and the direction of the flame will be deflected, resulting in the local overheating of the crucible, oxidation or small hole on the crucible wall. 碳化硅坩埚石墨坩埚廊坊
