Firing temperature is too low, poor quality of clinker, kiln forced to slow down, the unit heat consumption increases, but if the temperature is too high, easy to burn "kiln skin" and linings, affecting the long-term safe operation of the kiln, clinker Yi caking, easy to knot ring kiln, affecting product quality. Kiln temperature is low, the material burn well, forcing the kiln slowly turn affect the quality, if the kiln temperature is too high, easy to burn out kiln preheating equipment. In short, the ends of the temperature instability, thermal system also unstable, the production is not normal. So the entire calcination temperature must be stable, to make the calcination temperature is stable, we must pay attention to the following aspects: one, to keep the coal quality, such as analysis of coal, coal fineness, coal moisture, coal quality based on timely appropriate measures. Two, to keep the raw material easy to burn, impact Burnability raw material chemical composition of the factors that animate, raw material fineness, moisture and physical properties of raw materials. In accordance with the chemical composition can be roughly divided into: good burning materials, refractory materials, agglomeration and caking materials and both refractory materials. Good burning material ingredients appropriate, firing wide temperature range, strong adaptability, operation and easy to grasp, should generally be equipped with this material. Refractory materials and silicic acid saturation coefficient higher rate, when using the normal temperature calcined refractory material, the raw materials, "shadow" continues to move forward, if not take timely measures, resulting in the firing temperature getting lower and lower, and therefore appropriate kiln firing temperature and the temperature increased to strengthen materials burn, if necessary, to reduce kiln speed. Department of dissolved material caking coal matter saturation coefficient sum is too high or low, calcination produces too much liquid, so clinker caking, this material should be appropriate to reduce the amount of coal, grain control junction temperature. Both refractory and caking material, on the one hand because of high fire KH and SiO2 bad burn on one side or AI2O3 Fe2O3 content is too high due to make a very narrow temperature range firing, the firing temperature slightly higher caking temperature slightly low raw material "shadow" should be made to traverse direction kiln, burning this material, the operator must be ground, so ground running, ground view, adjust the air handling coal, if necessary, can temporarily reduce the volume of feed and kiln speed. All in all, the sintering temperature should be as control and change material composition, strict control of temperature agglomeration and remain stable. 3, with the relevant instrument to grasp the kiln temperature, kiln exhaust gas components (ingredients can be judged from the exhaust gas of coal with the situation) found that is not normal, take early and effective measures.
