ABSTRACT:
A kiln car which permits a substantial increase of product throughput per car per day through a kiln is disclosed. The kiln car includes a carriage for conducting the car through the kiln and a superstructure made of reduced mass of dense refractory components. A lower load-bearing base is arranged and constructed so that the load-bearing surface lies in a plane below the plane of the bench of the kiln to provide an increased cross-sectional area for product firing. The low-mass, load-bearing base includes a plurality of spaced, parallel, dense, refractory blocks which are resistant to thermal shock and capable of withstanding temperatures of about 1300.degree. C., and are positioned transversely on the carriage. Each block is formed having aligned and spaced bores or sockets for mounting a column of dense refractory in each bore. A plurality of elongated, dense, refractory members or spacers are positioned around the perimeter, and are mounted between the parallel-spaced, refractory blocks to lock the blocks in place. Dense, refractory, product-supporting members are disposed in spaced, parallel relation and are supported by the parallel-positioned, refractory blocks to provide a product-supporting surface. A low density low heat capacity, refractory material is interspersed between the parallel-spaced, refractory blocks below the product-supporting members to provide a base of low mass having reduced thermal conductivity, so that heat damage to the carriage assembly, including the wheels and bearings, is obviated.
