Overview
Walking-type heating furnace is a furnace type that is widely used and developed rapidly. It is the main furnace type that replaces push-saw heating furnaces. It has an incomparable advantage to push-steel furnaces.
Advantages of walking heating furnace:
1. Flexible heating
2. Good heating quality: there is a certain gap between the billets, the billet is heated on all sides, the temperature is relatively uniform, the billet surface has no scratches, and the billet has no black marks.
3. Unrestricted furnace length: It is not restricted by the push-to-steel ratio, and can heat thin and long raw materials.
4. Convenient operation: according to the production situation, the blanks in the furnace can be withdrawn from the furnace, shortening the furnace opening time, because there is a gap between the blanks, it is not easy to stick to rigid
5. The position of the blank can be accurately controlled to facilitate automatic operation.
