![]() Rotary kilns the stringent requirements
Where new masonry lining to go through baking, with appropriate temperature gradually evaporation, drying kiln lining, its purpose is to make the production of dry kiln lining does not burst fracture, to prolong the life of kiln lining, is conducive to the kiln long- term safe operation. If after drying on the ignition, it is easy to produce high temperature thermal cracking, shorten kiln lining life. The new kiln not only to the whole kiln drying, and chimneys, smoke chamber brick masonry and other places where there have to be dried. Stages starting from the kiln preheater kiln gradually to move a certain distance intervals put a bunch of wood, each pile bake about 1-2 hours, every half hour during kiln drying kilns need a quarter turn, prevent bending kiln and kiln lining surface to heat evenly. Dazhong after repair kilns firing zone generally middle stacked pile of firewood can be. Before the end of the drying kiln, but also multi-wood on the fire until the fire is transferred to Wong ignition operation. When the firing zone magnesia refractories, because poor thermal stability, so slowly warming is strictly prohibited fierce heat up. Drying can be injection, drying kiln is about 6-8 hours, fuel consumption is about 1.5-2 tons, can also be wood drying. When the oil, the fuel injection after two hours of continuous kiln LP 6-8 hours later, when the brick surface whitening, can be transferred to the ignition of pulverized coal injection operation. Different types of refractory materials, different requirements kilns. The above article by Henan YuFeng Heavy Machinery finishing post!
