摘　　要：采用ANSYS软件研究了钢卷在全氢罩式炉退火过程中的加热、保温和冷却阶段27 m/s、30 m/s、33 m/s、36 m/s和39.3 m/s的氢气流速对其温度场的影响。结果表明:在加热和保温阶段,随着氢气流速的增大,钢卷外热点和冷点的温度均升高,外热点与冷点的温度差减小;在冷却阶段,随着氢气流速的增大,冷却后钢卷的温度下降,外热点与冷点的温度差减小。The effect of hydrogen flow rates of 27,30,33,36, and 39.3 m/ s at heating, soaking and cooling stagesduring annealing of the steel coils in a all-hydrogen bell-type furnace on temperature field in them was investigatedby ANSYS software. The result showed that temperature of the external hot spot and cold spot of the steel coils allincreased, and the temperature difference between the hot spot and the cold spot decreased with the increase inhydrogen flow rate at the heating and soaking stages. and that at the cooling stage, with the increase in hydrogenflow rate, temperature of the steel coils dropped, and the temperature difference between the hot spot and the coldspot decreased.
