The second rib wave of the incoming strip material is relatively serious; 2. The strip material is slag-included due to melting and casting; 3. The edge cracks are not found), the strip will break in front of the air cushion curing furnace or at the straightener during the production process. Since the air cushion curing furnace equipment used is the air cushion furnace designed by SMS, the tension in the furnace area is twice that of the unwinder, and the circulating air volume is large, if only the head and tail running belts of the broken strip are glued with high-temperature tape, it is easy to break again in the air cushion curing furnace.

[0003] At present, the lowest setting temperature in the air cushion curing furnace is 190℃, and the highest temperature is 280℃. Personnel cannot re-stitch when the furnace is working normally. Therefore, the air cushion curing furnace needs to be shut down after each belt break, and the temperature in the furnace will be lowered before processing. The abnormal downtime caused by each belt break is 16 hours, which will reduce production efficiency. In addition, the natural gas consumption for each shutdown and restart is 14,000 cubic meters of natural gas and 13,000 kWh of electricity. The current production speed of the air cushion curing furnace is 140m / min, and the production capacity is 210 tons, which will cause energy loss, thereby increasing production costs and inconvenience in use.
