在现代生产条件下,甚至在接触表面堆焊硬质合金时,高炉装料设备的耐久性(特别是具有组合式料钟的装料设备)是十分低的,同样要保证旋转布料器的可靠气密性也有很大困难。但是,在建造巨型高炉的新式装料设备时,保留把最初一批炉料装到喉壁处的装料原则(以便保证碎块在炉喉半径方向上以必要的不均匀性分布)和保留按站位制工作原则(以便达到矿粉在全料柱容积中的规则分布)无疑是合理的。按站位制工作应保留的另一原因在于:当高炉炉况失常时(管道行
In modern production conditions, the durability of the blast furnace charging equipment (especially the charging equipment with a combination chronometer) is very low even when surfacing the hardfacing alloy, and also to ensure the reliability of the rotating distributor Gas tightness is also very difficult. However, in the construction of new charging equipment for gigantic blast furnaces, the principle of charging the first batch of charge to the throat wall is retained (to ensure that the fragments are distributed with the necessary inhomogeneities in the direction of the throat radius) and retained The principle of working station system (in order to achieve the rules of the distribution of slag in the volume of the whole column) is undoubtedly reasonable. Another reason why station work should be retained is that when blast furnace conditions are abnormal (ducts)
