Comprehensive solution for lining the socle of an electrolyzer with contemporary refractories and heat insulating materials

OAO Borovichi Refractory Plant has developed a number of new forms of product for lining the socle of an electrolyzer for obtaining primary aluminium. Results are provided for research on thermal insulating vermiculite products of the ITOM (integral heat insulation refractory materials) series and barrier materials: dense fired refractory articles BorAluBar, mastic for filling joints BorAluPlast, and dry barrier mixture BorAluMix. Newly developed products will make it possible to propose to aluminum producers a comprehensive solution for lining the electrolyzer cathode with contemporary refractories and thermal insulating materials with a high technical resource. Use of the materials will make it possible to prolong electrolyzer service life by several degrees.[PUBLICATION ABSTRACT]
