After the material connection plate body 1 is heated, it passes through the first cooling pipe 6 and the second cooling pipe 22 and is connected to the original designed circulating water pipe network system of the factory. The water inlet pressure in the pipe network system can be continuously maintained at 0.3Mpa, so that the first cooling pipe 6 and the second cooling pipe 22 cool the upper and lower surfaces of the material connection plate body 1 and take away the heat, so that the overall working temperature of the material connection plate body 1 is maintained at about 180-200℃, which greatly improves the service life of the component and provides a guarantee for the smooth operation of the production process.

After the receiving plate body 1 is heated, it passes through the first cooling pipe 6 and the second cooling pipe 22 and is connected to the original designed circulating water pipe network system of the factory building. The water inlet pressure in the pipe network system can be continuously maintained at 0.3Mpa, so that the first cooling pipe 6 and the second cooling pipe 22 cool the upper and lower surfaces of the receiving plate body 1 and take away the heat, so that the overall working temperature of the receiving plate body 1 is maintained at about 180-200°C, which greatly improves the service life of the component and provides a guarantee for the smooth operation of the production process. By setting the reinforcing plate 4, the deformation resistance of the receiving plate body 1 is effectively increased, and the cracking of the receiving plate body 1 is effectively prevented.
