连续板坯加热炉在均热段由实炉底发展到架空炉底后,由于滑道水管的冷却影响,在加热钢坯上形成了“黑印”,致使轧制困难,燃耗增加,板材厚度不均等。为此国内外对热滑轨做了大量的研制工作。鞍钢中板厂从七十年代初使用 Cr28半热滑 Continuous slab furnace in the soaking zone from the real bottom of the furnace developed to the bottom of the overhead, due to the cooling effect of the chute pipe, heating the billet formed a “black”, resulting in rolling difficulties, fuel consumption increases, the thickness of the plate Not equal. Therefore, a great deal of research work has been done on the hot slide at home and abroad. Angang plate factory from the early seventies Cr28 semi-thermal slip
