The rebar and wire rod rolling mill production line's final products are hot rolled rebar and wire rod. The finished bar is cooled by a walking beam cooling bed, then being cut, collected, packaged and stored in the warehouse.
The main production process is as follows:
The continuous casting billet is heated to a suitable temperature by a natural gas reheating furnace and is fed by a conveyor roller to a 550 rolling mill for rough rolling. After the roughing mill rolling passes, it is sent to the medium rolling mill to be rolled into a straight strip. The finished bar is cooled by a walking beam cooling bed, then being cut, collected, packaged and stored in the warehouse.
The annual output of the rebar and wire rod rolling mill production line is 500,000 tons, and the whole rolling mill plant adopts full continuous arrangement.
