Description

A system and method for automatic vacuum coating and hot rolling of composite panels

technical field

The invention belongs to the technical field of sheet metal processing, and particularly relates to a system and a method for automatic vacuum coating and hot rolling of composite sheets.

Background technique

Composite panels have excellent comprehensive properties and are widely used in shipbuilding, petrochemical, nuclear power and other fields. As a resource-saving product, low-alloy steel/stainless steel clad plate not only has the corrosion resistance of stainless steel, but also has the good mechanical strength and processing performance of low-alloy steel. Introducing an iron-cobalt-nickel-copper alloy layer between the interlayers of the clad plate, on the one hand, hinders the diffusion of carbon between the base layer and the clad layer, avoids the formation of intermetallic compounds, and ensures the corrosion resistance of the clad plate. In addition, due to the existence of the iron-cobalt-nickel-copper alloy layer, the diffusion rate of stress corrosion cracking can be significantly reduced. Under the existing technical conditions, the general method of preparing stainless steel composite billet and hot rolling is: first, use a vacuum coating device to coat the composite billet; secondly, put the coated composite billet in a heating box and heat it to the rated value temperature; finally, push the heated composite billet into the hot rolling device for hot rolling. This method has the following drawbacks: on the one hand, this method consumes a lot of manpower, and the manual error rate is high, and the operating environment is a high temperature environment, which is dangerous to the operator; on the other hand, the heated composite billet is transferred to hot rolling. During the installation process, the transfer time has a great influence on the temperature of the blank, and the transfer process cannot be precisely controlled due to manual operation.
