Characteristics analysis of convection and radiation in industrial plants with high temperature heat source

Tests the characteristics of indoor temperature, air velocity and radiant heat intensity of a steel hot rolling plant in Xian during summer and winter. The results show that the average indoor temperature is over 35 ℃ in summer and below 10 ℃ in winter, the average indoor air velocity in winter is higher than that of in summer, the variety of radiation intensity in summer is compliant with that of in winter, but the direction mean radiant temperature in summer is higher than that of in winter, and the direction mean radiant temperature is far higher than the indoor air temperature.
