Rotary kiln repair approaches encounter situations deformation

1, cylinder bending repair method. For tube bending deformation, deformation section in the lower part of the cylinder to draw the mark of the tubular body 180

degrees, slow heating for 1 hour, the cylinder further 90 degrees, slow heating for 30 minutes, further 90 ° , slow heating for 30 minutes, and so forth, were

transferred four times; cylinder will stop at the original location of 180 degrees and continue to slowly heat up, and every minute 1/15 rpm slow rotational speed of

about four hours. After the end of the heating feed production, feeding amount should be the normal amount of 60% to 80%, in operation cylinder deformation will

gradually decrease. 2, the pressure bearing method. With 300 tons jack, bump deformation zone in the cylinder to force support. Production up and down curved

bearing, jack stand on the middle of the power jack forced by support from the deformed part, while in the afterburner flame local heating can be used to accelerate

the deformation recovery. 3, Wabu repair method. When a large area of ​​the cylinder localized deformation, and the deformation area was badly damaged, we can

use this method to replace the parts of the plate. Must first determine the location and size of Wabu in preparing the site ends Wabu set "m"-shaped support, to

prevent deformation of the cylinder. Welding steel plates to be produced, the arc-shaped Bending roll formed and polished groove, and then welding a steel plate to

be inlaid into digging mouth segmented with low hydrogen electrode welding. The above article by Henan YuFeng Heavy Machinery finishing release, reproduced,
