推钢式加热炉新型钢坯滑轨的研发与应用

The Development and Application of New Billet Rails in Pusher-Type Reheating Furnace

摘要: 针对目前中(宽)厚板生产线所使用的推钢加热炉钢坯滑道存在的一些问题进行了分析，根据实际情况研发了一种用于推钢式加热炉的新型钢坯滑轨。在某宽厚板生产线的推钢式加热炉上成功地应用了这种新型钢坯滑轨。使用后，钢坯黑印数量明显减少，且黑印温差由原来的50℃~60℃减小到20℃~30℃，减少了氧化铁皮的生成，提高了产品的成材率，降低了加热炉燃耗,，提高了加热炉产量，取得了良好的经济效益。

Abstract: This paper analyzes the issues of billet rails in pusher-type reheating furnace which is widely used in thick plate production line. According to actual situation, we researched and developed a new billet rails for pusher-type furnace. The new billet rails in pusher-type reheating furnace have been successfully applied in a heavy plate production line and achieved good economic results. The number of black mark was significantly reduced and the temperature difference between black mark and hot billet was reduced to 20˚C - 30˚C from 50˚C - 60˚C. The oxide scale was reduced, at the same time the yield rate of products was improved. The fuel consumption of heating furnace was decreased but the yield of the furnace was increased.
