Boiler shell rolling process
Thread Content
Which rolling process is suitable and cost-effective? What’s the difference?
In fact, there’s no need to hesitate – the decision is based on the requirements of the manufacturing process and the available equipment. For example, when the plate thickness reaches a certain level, cold rolling becomes impossible, and hot rolling is necessary; moreover, there aren’t many manufacturers that possess the equipment and technology for hot rolling.
Boiler manufacturers typically establish procedures for the cold rolling of boiler shells (for example, Chapter 4 on Cold Rolling of Boiler Shells in the \"General Procedures for Industrial Boilers\" compiled by the Shanghai Industrial Boiler Research Institute), and the equipment used is usually a three-roller or four-roller plate rolling machine. And what do cold calibration and thermal calibration refer to?
