目前对常压柱状流及中高压射流的冷却能力一般仅停留在定性认识基础上,而没有从量上揭示这两种喷流形式冷却能力。利用ANSYS对中厚板控冷及淬火中常压柱状流及中高压喷射流冷却的钢板温度场进行了实验及数值模拟,研究两种不同形式的喷流在实际冷却中温降速率大小,研究两种喷流的最大冷却能力,得到两种喷流在实际装置中最大淬火钢板厚度,从而为控冷及淬火装置的选型及设计提供理论依据。
At present, the cooling capacity of atmospheric and cylindrical jet and jet of medium and high pressure are generally only based on the qualitative understanding, without revealing the cooling ability of these two jet flows in quantity. Experiments and numerical simulations were carried out using ANSYS software to simulate the temperature field of steel plates cooled by cold and quenched mid-pressure columnar flow and medium- and high-pressure jet. The two different types of jet flow temperature drop rates during actual cooling were studied. The maximum cooling capacity of the jet, get the maximum quenching plate thickness of the two jets in the actual device to provide a theoretical basis for the selection and design of the control cooling and quenching device.
