The number of RUSAL’s cells with un-shaped, eco-friendly materials of the insulation and part of the refractory – materials that can be re-cycled in the amount of no less than 80% – has been increased up to 1,600. Because of said materials’ lower density and re-cycling, it is possible to reduce the amount of SPL requiring landfilling.
The paper elaborates on technologies to both expand and improve pyrolysis products from carbon raw materials, so that products from lignite, charcoal and grass culms can be used as thermal insulation in cells with un-shaped lining materials.
The paper provides the results of researching both earlier-tested and new un-shaped carbon materials. New materials are compared with earlier-tested and conventional lining materials, in terms of efficiency and performance. Additional information is given about the use of such materials, including equipment for their installation. Autopsy results are provided for different-age cells lined with un-shaped materials.
