Making large steel cylinders usually requires tools and materials such as chain-reversing, cutting machine, steel plate and electric welding machine. The following is a simple production process:

1. Select the steel plate with appropriate size, and cut the steel plate into the required length with a cutting machine.

2. Bend the steel plate into a circle, and gradually butt the two short sides with chain block to fix the first weld. Care should be taken to maintain the roundness of the steel plate.

3. Repeatedly use chain block to roll up the steel plate along the long side in the direction of non-welding, so as to ensure that the steel plate is clamped after rotating, and then use electric welding machine to weld each weld layer by layer until the steel plate becomes a complete big cylinder.

4, check the quality of vat, such as processing bad parts timely review and correct.

5. Scrub the surface of the large cylinder for subsequent treatment or use.
