Abstract Two-dimensional mathematical model of checker chamber was developed. Comparison between the calculated results and actual measured data in Xuansteel was done in order to verify the availability and accuracy of the mathematical model. The influence of checker brick design, dome temperature, mixed air operature and operating period on blast temperature was studied. The results show that: for each diameter of checker brick, there should be an optimal relative open area. Blast temperature can be enhanced by optimizing the correspondence between diameter and relative open area. When the preheating temperature of gas and air increase 100℃, the dome temperature and blast temperature will increase 80℃ and 72℃, respectively. Shortening operation period can significantly improve the blast temperature. It should choose reasonable operation period according the combustion burner ability in order to guarantee the gas and air mixing and burning efficiently.

Key words： blast temperaure checker bricks dome temperaure mixed air operation operation period
