摘要
为改善底喷式淬火槽的冷却均匀性,从入水口方向和变径方面对淬火槽结构进行优化,研究了不同淬火槽结构对淬火冷却的影响。结果表明:在相同边界条件下,入水口方向改为切向后,钢管两侧流速有了显著提高,可有效提高淬火槽的冷却能力;采用过流截面逐渐收缩的变截面淬火槽,钢管轴向及内、外壁面的冷却均匀性均优于等直径淬火槽。
To improve the cooling uniformity of bottom spray quenching （BSQ）, the structure of quenching tank was optimized by changing the inflow direction of water and variable diameter quenching tank. the influence of quenching cooling at different quenching tank structure was studied. The results show that the flow rate on either side of the steel tube is improved significantly when the inlet direction changes into tangential under the same boundary conditions, and the cooling capacity of quenching tank are improved effectively. Through the use of the variable cross-section quenching tank, the cooling uniformity of axial or the cooling uniformity of both inside and outside of the tube surface is more superior than the uniform diameter quenching tank.
