[0003] Annealing of cold-rolled steel pipes refers to the heat treatment process of steel pipes during the production process. In order to solve the problem that the annealing device adopts a stacking method to anneal the steel pipes, multiple sets of adjusting screws are installed inside the annealing device. The steel pipes during processing can be fixed by the adjusting screws.
