By setting up an auxiliary structure, the effect of utilizing the waste heat generated in the sintering process is achieved, thereby reducing the waste of heat generated in the sintering process and improving energy utilization efficiency.

The protective pad can protect the top plate and prevent the threaded rod from causing more serious wear to the surface of the top plate during short-term use. By setting up the installation structure, the effect of allowing personnel to quickly connect the water outlet pipe and the connecting pipe is achieved, thereby improving the work efficiency of personnel.
