When the fan of the fan box is started, the fan drives the fan to rotate, and the fan performs the first air cooling on the high-temperature grinding balls in the lifting box, which can quickly reduce the temperature of the grinding balls and promote their rapid solidification to prevent possible deformation or internal structural defects.

[0017] (4) The present invention provides a protective wall scraping device, so that the splash box, protective strip, slide rail, slide bar, abutment protrusion and fixed rod cooperate with the scraper wheel, so that the splash box can block the splash generated by quenching, effectively preventing harm to the staff and protecting the safety of the staff. The protective strip can protect the grinding balls that roll into the quenching chamber from the inner wall of the splash box.
