研究生料反射炉炉底结确定,约一半的炉膛面积有25吋或小一些的中等炉结,从炉子烧嘴端延伸45呎的面积只有少量炉结。发现整个炉膛面积上覆盖有平均厚6吋的假底。Cr_2O_3、Al_2O_3和 SiO_2在炉渣层中发生分层,此现象是生料反射炉形成假底的主要原因。假底主要是由于 FeO·(Al,Cr)_2O_3聚集物沉降造成的,而此聚集物主要来自返回的转炉渣。此假底可能变成炉内一种坚实的永久性炉结,特别是在冰铜完全放出的情况下。从炉子的 Al_2O_3和 Cr_2O_3的物料平衡估计,铝铬铁矿每天聚集的平均速度大约是0.3吨或少一些。
The graduate student reflex furnace bottom determines that about half of the furnace area has a 25-inch or smaller medium-sized hearth, and the 45-foot extension from the furnace burner end has only a small amount of hearth. The entire hearth area was found covered with an average of 6 inches of false bottom. Cr_2O_3, Al_2O_3 and SiO_2 stratified in the slag layer, which is the main reason for the false bottom formed by the raw material reverberatory furnace. The false bottom is mainly due to the sedimentation of FeO · (Al, Cr) _2O_3 aggregates, which mainly come from the returned converter slag. This false floor may turn into a solid, permanent hearth in the furnace, especially if the matte is completely released. It is estimated from the material balance of Al 2 O 3 and Cr 2 O 3 in the furnace that the average velocity of the aggregates of aluminum chromite is about 0.3 ton or less per day.
