Determining the Effects of the Rate of Firing and Rapid and Slow Cooling on the Physical Properties of Fireclay Refractories*

Abstract

This investigation determined that the rate of firing, as specified in the standard test for the firing behavior of fireclay refractories, could be reduced without materially affecting the accuracy of the data obtained. The rate of cooling is found to be the cause of variations between test results and laboratory and factory resplts. NOTE: All volumes, weights, and drying methods carried on iu this study were
