Why do you pick the refractory you do? How do you choose? Wheredo you start the selection process? Where do you start? The answers to the first three questions is always a balance of competing interests between operations, purchasing, and the suppliers - the refractory engineer/selector is at across-roads to decide which is the correct material for each application. The goal of this book is not to select refractories for any individual facility or process or piece of equipment, butinstead to give a step by step process on how to do it. It will bea guideline, with enough depth to provide a good solid basis formaterial selection, but well short of the depth needed to actuallydesign a material from a refractory manufacturer point ofview. The examples are for steelmaking only as it makes up80% of the dollar spend of a steel plant (~50% of the worldwide refractory market); however, the process can be used in anyrefractory application in any industry. The background forthis book is 25 years of trial/error, success/failure, which has determined a tried and true methodology for success.
