。However, in the above-mentioned plate manufacturing equipment, the cooling table! Since all of the thick plates that pass through this area are cooled, when quenching the plate, it must be reheated from room temperature to the temperature required for quenching, which poses a problem from an energy saving perspective. Furthermore, even if you try to harden thick plates on the above line, simply arranging the hardening equipment will cause the flow of the entire line to stagnate and reduce production efficiency if the plates to be hardened and those not to be hardened are passed in succession. It will drop.
