1. Introduction 

The posts also have been made of silicon carbide or of the less refractory materials. In order to assure stability to the structure, the posts have been made with relatively large bases and tops. The intervening portion of the post has either been of the same cross section as the bottom and top, or, in the case of silicon carbide posts, has been cut away to give the post an I-shaped vertical section. I

Such silicon carbide posts have been the best available but have had a potential fault in that over a long period of service they oxidize slowly and as a result grow. This growth weakens the post somewhat, and what is more serious, changes the length of the post so that if a car structure is disassembled, the posts have to be carefully matched .for length before the car superstructure can be re-assembled. There have even been instances reported where the growth has been so great that the upper deck has had to be permanently removed for the car to be able to pass through the kiln. This, of course, results in an uneconomic loss of kiln capacity.

The peculiar splitting apart of the ends of shared posts led me to attempt to cure the trouble by simply placing a thin flat block of silicon carbide refractory (which has very high tensile strength) between the end of the post proper and the batts resting thereon. This proved an inadequate solution, however, as the'posts continued to collapse by failure at their ends underneath the silicon carbide block.
