Abstract：In order to investigate the low-temperature tempering ability of a naked-flame normalizing furnace in one plate rolling mill which was designed to have the medium and high temperature tempering ability from 250 ℃ to 650 ℃, the temperature measurement test with“black box”on the steel plate in the furnace under 150 ℃ temperature was made. The experimental results showed that under the condition of low furnace temperature condition, the gas temperature in furnace distribute unevenly, the side gas temperature is higher than the middle gas temperature and fluctuate sharply. The temperature difference of the steel plate in furnace is under ±2 ℃ along thickness direction, under ±5 ℃ along length direction and under 20-28 ℃ along width direction. The side part temperature of the plate is obviously higher than the middle part temperature of it.
