Wet spraying repair technology of lime kiln lining


Lime shaft kiln is a thermal equipment, in the long-term production by high temperature erosion, material erosion, especially the calcination of high temperature zone also subject to chemical reaction corrosion. The lining of lime shaft kiln must have the following properties: good volume stability at high temperature for a long time, good re-burning shrinkage, high mechanical strength, good wear resistance, compact structure, low porosity, good slag resistance (chemical corrosion resistance), good thermal insulation performance. The selection of refractory materials and the quality of lining determine the service life of the lime shaft kiln.
