Authors: C.E. Semler

Abstract

Refractories are the “Backbone of Industry”. Despite their great importance, refractories are frequently misunderstood, overlooked, and/or abused. The results can be extremely disruptive, costly, and even tragic. This paper defines seven main reasons for refractories problems in industry, and notes seven other contributing factors. Many practical examples are included. Based on an improved understanding of the reasons for refractories problems, as well as a thorough review of all related factors, it is possible to reduce or eliminate unnecessary and unexpected major expenses.
