BEHAVIOUR ANALYSIS OF METALLIC ANCHORING IN REFRACTORY WITH EXPERMENTAL SET-UP

Heat Power Engineering (M. Tech)

Refractories are heat reissuance materials that provide the lining for high temperature furnaces and reactors and other processing units. In addition to being resistant to thermal stress and other physical phenomena induced by heat, refractories are usually required to withstand physical wear and corrosion by chemical agents refractories are often exposed to environments above 538⁰C. Depending upon the application, refractories must resist chemical attack, withstand molten metal and slag erosion, thermal shock, physical impact, catalytic heat and similar ad adverse conditions, generally while at high temperature. Refractory materials have a crucial impact on the cost and quality of steel product. The diversification on steel products and their cleanliness requirement in recent year increased the demand for high quality refractory. This paper is intended to comprehensively give and account of knowledge related to refractory and its failure due to metallic anchoring by the experimental set up. In that we have provided the strain gauge over the metallic anchor which is embedded in refractory material as well as one strain gauge in castable to check the elongation of metallic anchor and castable at certain temperature. The result obtained from this experiment are helpful to understand the actual elongation of refractory material and metallic anchor at certain temperatures and this will help to calculate the life of refractory product for certain industries and to increase the economy of the industries.
