Title:
A QUENCHING DEVICE FOR STEEL BALLS
Document Type and Number:
WIPO Patent Application WO/2009/074036
Kind Code:
A1
Abstract:
A quenching device for steel balls comprises: a transport mechanism for transporting
rolled steel balls; a loading mechanism connected with the transport mechanism
for accepting steel balls from the transport mechanism; at least a spiral quenching
mechanism for quenching steel balls from the loading mechanism separately,
which is connected with the loading mechanism; a quenchant transport mechanism
connected to the quenching mechanism for introducing quenchant to the quenching
mechanism, the amount of which is consistent to that of the spiral quenching mechanism.
Steel balls could obtain uniform quenching effect and obtain hardness (HRC)
of 60-70 at improved quenching efficiency by using the quenching device.
