Abstract：

The influence of jet angle on temperature field distribution in high temperature heat-stored heating furnace was studied by FLUNT software. The results show that when the jet angle increases from 5° to 50°, the highest temperature inside the furnace and the average temperature at furnace exit are decreased linearly, and the average temperature inside the furnace increases at first and then decreases along the quadratic curve, meanwhile the highest temperature inside the furnace occurs near the nozzle and the relative distance is about 1 m. However, when the relative distance is larger than 1 m, the temperature has little changes and remains mild. When the jet angle is within 25°-35°, the temperature distribution inside the furnace and steel billet surface are more uniform. Considering all factors, the best heating effect occurs at the position of 1 m from the burner nozzle when steel billet is put in the heating furnace within the jet angle of 25°-35°.
