PHYSICAL PROPERTIES Physical property requirements for shaped and unshaped refractories are different For shaped refractories, the main requirements are their density and porosity and dimensional tolerance Monolithic (unshaped) refractories, on the other hand, have to be characterized with different parameters For plastics refractories, the workability and aging characteristics are the prime requirements,... comprehensive source of a broad range of technical aspects of refractories to be used by the refractory manufacturers, refractory material engineers, refractory lining designers, and industrial users of refractories Basic industry processing materials from the bowels of the earth require high-temperature processing and the use of refractories Refractories are necessary to insulate and control the process... refractories are the choice for steel making Since the exposure of refractories to molten metal/slag is a dynamic process, the tests simulating the conditions also need to be dynamic For steelmaking refractories, the rotary slag test (ASTM C874) provides close simulation of the conditions in steel-making refractories For iron-making refractories, primarily for blast furnace cast house applications,... 1481– 1492 Banerjee S Monolithic Refractories World Scientific Publications Private Ltd and The American Ceramic Society, 1998:151 Banerjee S Monolithic Refractories World Scientific Publications Private Ltd and The American Ceramic Society, 1998:51– 52 2 Fracture of Refractories Richard C Bradt The University of Alabama, Tuscaloosa, Alabama, U.S.A I ABSTRACT Fracture of refractories is considered from . of Refractories 1 Subrata Banerjee 2.
