Numerical Simulation of Quenchant Flow Field in Quenching Tank
The quenchant flow field in the quenching tank without or with loading was simulated using the Fluent6.2—a good commercial software.The simulation results show that the quenchant flow velocity in the middle of the matrix is very slow,without loading,the "effective quenching zone" is formed in the middle and top of the tank due to agitation and flow-equalizing system,and the flow field distribution of low flow velocity in centre and high flow velocity in edge is formed at the bottom of the tank.The distribution of quenchant flow field after loading has great changes,according to the shape of parts and form of clamp.Therefore,the flow-equalizing equipment of the tank was designed based on different parts and clamp,but not only considering the uniformity of flow field in the tank without loading.
