Rotary kiln cylinder

In large-scale mechanical equipment, the rotary kiln cylinder is used as the supporting and rotating parts of the equipment. During the operation of the equipment, it is exposed to high temperature for a long time. Because the rotary kiln mouth section is often burned and deformed, it is necessary to replace the new cylinder section when it is serious. If the new rotary kiln cylinder is not replaced in time, it will seriously affect the normal operation of the equipment.

Causes of deformation of the rotary kiln cylinder

1.The output is too large, and the wear of the kiln cylinder material is intensified, which is easy to cause overheat deformation of the cylinder.

2. The heat flow is too large, the cooling zone is short or even no, the working environment of the kiln mouth is bad, the temperature of the kiln clinker is 1300-1400 °C, and the secondary air temperature is 1000-2000 °C.

3.The rotary kiln cylinder temperature is too high, the thermal expansion is large, and the strength of the high temperature resistant material is seriously attenuated.

4.The looseness of the kiln mouth shield bolt causes the refractory material to fall off, thereby burning the cylinder.

5.Burning contaminated soil, improper handling caused serious corrosion of the cylinder, in severe cases will burn the kiln collapse.

6.Corrosion of kiln cylinder by sulfur, phosphorus and chlorine, in addition to reducing the thinning strength of the kiln cylinder, it will reduce the shaping of the steel and increase the brittleness of the steel, which may lead to the brittle failure of the kiln cylinder.

It can be concluded that it is very necessary to regularly detect the running condition of the components of the equipment, find problems and timely replace and replace the components. While improving the economic benefits of the enterprise, it can also effectively extend the service life of the equipment!
