冲天炉加料口寿命短,不仅在经济上是个损失,且由于加料口变形引起的卡料、挂料,将影响炉况的稳定和铸件质量。因此,研究保证从换热器上沿到加料口这一截炉衬的几何形状,使其在相当长的时间里保持相对稳定是有意义的。 Cupola feeding port life is short, not only in the economy is a loss, and due to feed port deformation caused by the card material, linked material, will affect the stability of furnace conditions and casting quality. Therefore, it is of interest to study the geometry of the lining from the heat exchanger to the feed opening so that it remains relatively stable over a long period of time.
