ANALYSIS OF STRUCTURAL ELEMENT IN REFRACTORY INDUSTRIES

Stability of refractory structural elements with metallic anchors in the refractory industries is checked by the application of Finite Element Method software i.e. ANSYS just to know the stress concentration within the structural element which is normally very difficult to understand due to heavy thermal loading .The Refractory structures exhibit similar structural behaviour as like block type or stone masonry structures subjected to temperature. Refractory structures are exposed to more complicated load environment, thermal expansion loading. The refractory lining is typically exposed to high temperatures resulting complicated stress/strain environment within lining structure. The refractory material properties tend to vary as a linear function of temperature. High temperature has a profound influence on the refractory material properties. At high temperatures, refractory materials has no longer remain totally elastic. Instantaneous plastic and time-dependent creep straining took place. As a result of structural investigation often requires the use of computerized structural analysis methods that can deal simultaneously with complex material and structural behaviour. In this research work, an attempt is made to demonstrate behaviour of refractory lining in the form of segmental brick arch with suspended refractory panel inclusive of metallic anchors subjected to thermal loading is studied. Its behaviour is analyzed and studied in the form of 3D Model for segmental brick arch and corresponding suspended anchor roof design. Results demonstrated that 10 mm dual leg metallic anchor is capable to withstand thermal load by 750 mm x 750 mm refractory panel as a suspended roof
