Control rotary kiln tire size of the gap What is the role?

A rotary cylinder forming the flat diagonal thermal equipment, work at high temperatures and under heavy load, its tilt and uniform temperature throughout the different amount of thermal expansion, and its formation is a very complex process. From the point of view of a cross section can be considered as an ellipse. It changes constantly and repeatedly with positive and negative characteristics. A turn in there six times. Refractory cylinder body with the effect of the arch by the rotation of the rotation of the cylinder, which curvature of the neutral surface of the cylinder along with the rotation of the alternation is periodically change. It changes with the cylinder amplitude is exacerbated by an increase in lateral deformation. Today's new dry kiln are used loose sleeve floating tire, tube plate diameter and the gap between the tire diameter is very important. Make a big cylinder deformation increased, plate and cylinder welding seam stress increased, resulting in rupture and shorten the life of brick; while also making the rounds with the relative sliding between the plate increases, increased wear; gap is too small cylinder volume expansion will appear interference, causing the occurrence of necking, but also make a big barrel distortion occurs. Whatever the deformation will cause loose bricks, arranged twist and break, which occurred off the red brick kiln accident. Will lead to more serious cracks cylinder, causing damage to the cylinder. Therefore, with the rotary kiln must be controlled within a certain range of the gap. Please indicate Henan YuFeng Heavy Machinery
