Boiler drum is one of the important components of boiler body, and its manufacturing requirements are strict. As a powerful boiler manufacturer, ZOZEN Boiler introduced advanced plate rolling equipment while standardizing the plate rolling process, to ensure better quality of the boiler drum. In the modern workshop of ZOZEN Boiler, the steel plate after pretreatment such as derusting, milling and chamfering will be transported to the drum workshop, and then rolled into the workpiece for manufacturing drum by the advanced four-axis numerical control bending machine.
