ABSTRACT
Of most importance in evaluating the structural behavior of refractory lining systems understands the concept of load types. There are two types of loads that can be imposed on a structure. They are stress-controlled load and strain-controlled load. By understanding the load types imposed on a refractory lining, one can better decide on the most desirable refractory material mechanical properties and refractory lining geometry that will result in the best lining design. The primary result of a stress-controlled load is that the stress in the structure can be determined with knowledge of only the structural geometry. A strain-controlled load on refractory structures is an internal load that is applied to the structure. More specifically, a strain-controlled load is an imposed strain rather than an imposed stress on the structure. For the refractory structure, the thermal expansion of the structure is an imposed strain and is classified as a strain-controlled load.
