The goal of this study is to investigate the effects of strip steel surface temperature, nozzle stretching length as well as the distance between nozzle and strip steel surface on the heat transfer property during gas jet cooling through the continuous annealing furnace process. It is observed that strip surface temperature has no effect on the convection heat transfer coefficient. Deviation emerges between the experimental results and the calculated values of Martin formula with increasing Reynolds number and reaches even about 15% when Re>60000. Regression equation coefficient C relating to nozzle box structure achieves the maximum value with H/B increasing to 8. Appropriate length reaching out can strengthen heat transfer when H/B<10. The method of calculating the convection heat transfer coefficient can be presented using Nu=CRe^0.8Pr^0.4.
