Cool in the pit (box)

After forging, the cylinder forgings are placed in a pit or iron box for closed cooling, or buried in sand, lime or slag in the pit for cooling. Generally, the sand temperature of forgings should not be lower than 500 degree : The thickness of the surrounding sand should not be less than 80mm. The cooling rate of the cylinder forgings in the pit can be adjusted by different insulating materials and heat preservation media.
