Example Embodiment
[0021] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0022] Such as figure 2 The shown new type of roll surfacing process is the best embodiment of the present invention, and is used to process the roll pass on the roll base. figure 2 The lowest temperature in is normal temperature.
[0023] First of all, it is necessary to machine a pass-shaped rolling groove on the substrate. The pass roll groove includes a pass groove bottom 1, a pass side wall 2 located on both sides of the pass bottom 1 and a pass R arc 3 connecting the pass bottom 1 and the pass side wall 2.
[0024] Then include the following processing steps:
[0025] A. Substrate preheating, the preheating temperature of the substrate is 200℃±10℃;
[0026] B. Perf...
