SP57-07

Date:

Author(s):

Publication:

Symposium Papers

Volume:

57

Abstract:

Refractory concrete, unlike Portland cement concrete, is not commonly used as a structural member, although in some applications it may contribute to overall structural integrity. More often refractory concretes are used to protect structural members (commonly steel) and are considered to be lining or barrier materials. The use of thermal conductivity, thermal expansion, strength, and reheat shrinkage data is discussed relative to their use in designing with refractory concrete.

Abstract:

The use of refractory castables in steelplant applications is expanding continually, and their use has been accelerated by periods of energy and/or fired-refractory-material shortages. . .Projections for the future of refractory concretes in the steel industry suggest a trend toward the use of high-purity and synthetic raw materials and greater interest in composity materials containing metallic fibers.

Publication:

Symposium Papers

Volume:

57

Abstract:

Refineries and petrochemical plants have a variety of locations where process temperatures of 1000F to 3000F must be contained. . .A review is given of the various process units in typical refining and chemical process plants that use refractory materias. Criteria for refractory selection, design considerations, and installation techniques are detailed and suggestions on dry-out procedures are given.
