Rotary kilns set high demands for back-up insulation systems in steel plants. Production faces costly maintenance and decreased service hours, as a result of the extreme conditions inside the kiln. Some of the challenges include damage to the steel shell and unstable thermal conditions inside the kiln.
Skamol offers M-EXTRA moler bricks as a back-up insulation system in rotary kilns. M-EXTRA is designed through careful field-testing, showing the bricks excellent insulation properties combined with exceptional strength. This provide our customers with the following benefits:
By using M-EXTRA it is possible to significantly increase the life span of the rotary kiln and save energy at the same time. By maintaining its insulation properties in service temperatures up to 1,000°C, M-EXTRA is documented to reduce energy consumption with up to 50%!
Follow the link to our Heat Transfer Calculator and find out how much thermal loss you can achieve by using our M-EXTRA insulation system.
M-EXTRA’s material composition makes it resistant to alkali attacks, which shields the mechanical parts and steel shell of the kiln. The brick's structure increases in strength in temperatures up to 900°C, which gives the kiln increased resistance to the pressure of the expanding refractory lining, thereby also lowering risk of shell deformation.
