Abstract:The 2m2 Shaft furnace shell is made of steel plate by rolling and welding, and it needs to be annealed after welding for stress relief. By formulating a reasonable annealing process and taking effective anti-deformation measures, the shaft furnace shell shows an excellent performance after welding and annealing, with the deformation living up to the requirements, and the product quality complying with the requirements of the drawings and technical agreement.
