Type rotary kiln shell shape and its advantages

Article source：yufeng

Rotary kiln is the equipment more important part in the production of steel plates when the first segment of its rolled into a cylinder, such as the installation by

welding technology to connect together. In the calcined material, due to the different materials, occurs in the cylinder body different physical and chemical

properties, in order to better calcined material, adapted to the different requirements of the reaction with the material, the cylinder can be made in different shapes.

Generally cylindrical shape seen in the following categories lines of different types with the characteristics of the cylinder is not the same. 1, the straight line of the

type of kiln, the diameter of the cylinder is constant, so the manufacture, maintenance and other aspects is relatively simple, using a variety of components and

refractory sizes relatively small, easy to manage. Because of the same diameter, for improving the heat transfer area, increasing the kiln poor practicability. 2, one

end of the extended end of the expansion for the case, the cold end may be enlarged, it can be expanded hot end. The advantage of expanding the cold side, to

increase the heat transfer area, improve the burn-in capacity, reduce the kiln exhaust gas temperature, heat loss, while the kiln speed decreases, reducing the flying

loss, help to reduce material consumption. The hot end is to expand the diameter of the combustion zone becomes larger, expanded the volume of the combustion

zone to increase and improve the combustion zone of the heat capacity of the kiln will help improve production, reduce knot ring. 3, both ends of the ends to

expand the so-called cold end is to extend and hot side while expanding, expanding the hot end of the kiln firing is to improve the ability to expand the cold end is

to improve the kiln preheat capabilities, and can be reduced for the middle save steel. For the latter two cases the rotary kiln shell shape, in the refractory

specifications and dimensions of choice, than straight kiln charge and trouble. For the above three types of cylinder, you will need based on the actual production

needs to choose, whether you choose what kind of kiln type, Heavy Machinery Co., Ltd., Henan YuFeng think you can be tailored. Please indicate Henan YuFeng
