Rolling of bimetallic plates
The bimetallic plate is divided into cold rolling ,hot rolling,hot rolling and then cold rolling depending on the heating. Its products are divided into three categories:cold rolled bimetallic plate,hot rolled bimetallic plate,cold and hot rolled bimetallic plate. Their rolling process parameters are determined experimentally.

1.    Cold rolling
If the strength of the two components is lower and the shape is higher, such as a copper clad aluminum plate, the cold rolling process can be performed despite a certain degree of explosion hardening. If the capacity of the rolling mill is large enough, the thick composite slab can be rolled to any small thickness without intermediate annealing. silver clad copper plates, copper clad titanium plate can also be cold rolled, except that they need to be annealed in the middle to be rolled into a thin plate.

2.    Hot rolling
For one of the higher strength and lower profile metal combinations or combinations, for example, stainless steel clad steel plate, and titanium clad steel plate require heating. The temperature of the heating depends on the physical properties of the components and the characteristics of the interaction at high temperatures. The test results indicate that the hot rolling heating temperature of the stainless steel clad steel plate can be as high as 1150 ° C, and the hot rolling heating temperature of the titanium clad steel plate is preferably not more than the phase transition temperature of titanium. During the hot rolling process, especially for metal combinations with intermetallic compounds on the phase diagram, the first pass has a high processing rate and is rolled to the desired thickness (thickness ≥ 4 mm) at the fastest speed.

3.    Cold rolling after hot rolling
For example, a stainless steel clad steel plate having a thickness of 3 mm or less requires cold rolling of the hot rolled intermediate plate. An intermediate annealing of 1-2 times is required during the cold rolling process. In order to obtain a bimetallic sheet of a given organization and properties, a finished annealing is also required. For the corrosion-resistant stainless steel layer, in order to restore its corrosion resistance, the bimetallic sheet is also subjected to solution treatment.
