The production cycle is smaller, the production is more. The soaking temperature was set to 330°C. And make sure the material thickness as 12mm. Then changed the soaking time and measured the decomposition rate. The results were shown in Figure 6. 32 Figure 6 Soaking time vs. decomposition rate with thickness 12mm at 330 °C The Figure 6 showed the relationship between the soaking time and decomposition rate with thickness 12mm at 330°C. It can be seen from Figure 5 that the decomposition rate was enhanced by extending the soaking time.

Results and Discussion Effect of Roasting Temperature Effect of roasting temperature on removal and solidification of sulfur and arsenic is indicated in Figure 2. According to Figure 2, when roasting temperature increased(300~600°C), the removal and solidification ratios of sulfur and arsenic were getting higher. 60%, respectively. 52%, respectively when it came to 400°C. Within the range of 500D to 700D, temperature had less effect on removal and solidification of arsenic. Similar to the effect of arsenic, when temperature varied from 300D to 400°C, desulfurization and solidification ratios of sulfur rose greatly.
