Abstract

Multilayer lining consists of dense refractories for a working layer and insulating refractories and is used for decreasing heat losses through the rotary kiln shell. The production of refractory brick with gradient porosity functioning as multilayer lining may be made using the concretes. In this article the results of low-dense fireclay concrete development with the use of fine-grain fireclay aggregate and porous filler (reject and light scrap of lightweight refractories) for the insulating layer of concrete shape are given. The influence of substantial and grain composition of the aggregate on the properties of low-cement fireclay concrete has been investigated with the use of simplex method of experimental planning. The best correlation of porous aggregate and fine-grain fireclay aggregate in the content of concrete mixture is found which ensure the formation of strong structure of low-dense concrete. Two-layer concrete shapes with gradient porosity, consisting of dense and low-dense concrete have been produced at a plant. Industrial tests of two-layer concrete shapes with gradient porosity in roasting zone of rotary kiln for kaolin burning showed their high service properties
