一、 耐火纤维井式回火炉的结构 1)炉体结构(见图1) 由于硅酸铝耐火纤维毡在平面方向上强度差,导热性大,因此炉膛壁采用层叠式的,也就是将耐火纤维毡切割成如图2。层叠炉壁在组装时预压总纤维毡高度的10％,这样的炉壁结构强度增高了,保温性能也好了,也就能承受一定程度的机械碰撞。另外,为了使纤维炉 First, the structure of refractory fiber pit furnace 1) Furnace structure (see Figure 1) As aluminum silicate refractory fiber mat in the plane direction of the poor strength, thermal conductivity, so the furnace wall laminated, that is, fire-resistant Fiber mat cut into Figure 2. Laminated walls pre-press the assembly of 10% of the total height of the fiber mat, such a furnace wall structure increased strength, thermal performance is also good, it can withstand a certain degree of mechanical impact. In addition, in order to make fiber furnace
