Ways to improve the quality Prebaked


Only the upper and lower oven temperature 50 ℃, while the majority of our manufacturers baking temperature difference between up and down more than 200 ℃, which need to increase the baking temperature. To achieve the anode baking process products in the required temperature, which is a waste of energy, but also so that the anode of uneven quality. Taiwan is also a reasonable temperature curve anode quality assurance. Anode heating curve too fast will crack, increasing the resistivity, also cause deterioration of bending strength. Generated when the anode baking anode will occur when cracks cracking,[link widoczny dla zalogowanych], affecting production. The final temperature is also very important, if the calcination temperature did not reach or too high,[link widoczny dla zalogowanych], it will bias the anode performance, deterioration of mechanical properties, permeability increase, particularly in the anode baking process did not reach the temperature, carbon residue in the electrolysis process of shedding will be very clear, so that the electrolyte viscosity,[link widoczny dla zalogowanych], increased consumption of electrolysis process as the anode baking inadequate mechanical strength is too low, the resistivity is bigger. According to foreign to the information, when the resistance rate of 115 {) ℃, is reduced by 100 ℃,[link widoczny dla zalogowanych], the resistivity will increase 5n, m. Calcination temperature increased from 1150t ~ 1250 ℃, the resistance rate of change is very small (see Figure 1). Calcination temperature on the bullock-caking agent in the performance of that focus bridged impact, size composition and binder coke content on the anode density impact. Figure 1 shows that the coke calcining temperature ≥ 1150 ℃ calcined when the series resistance of the anode is not,[link widoczny dla zalogowanych], and calcination temperature a bar ridicule. Z
