Thermal Analysis Of Cover Plate Of Galvanizing Bath Tub At Bridge 26 Roof Co. I Ltd. By Shape Modification

This project is aimed for thermally analyzing stress and strain on cover plate of galvanizing bath tub at Bridge 26 Roof co. I Ltd in order to maintain 450C in bath tub. Along with analysis part cover plate shape was modified due to its continuous use 26 prevailing conditions at the workshop. The cover plate consist of insulating materials compacted to retain the heat in the bath tub. The thermal convection of air is less than thermal resistance of insulating materials used thus heat loss is negligible. Thermal convection air 0.0579 w m k Thermal Resistance Insulator 7.046 w m k. Thermal analysis report show at 450C. Deformation is effecting end portion 2-3 mm. Stress 26 Strain at that portion is also low 0.1-0.3 Mpa. Heat transfer of air is more than insulating materials. Thus Heat transfer rate of Insulating materials being low they dont conduct heat from the bath tub to the atmosphere. So temperature of the bath tub is maintained. QA 1806.25 W Heat transfer rate of Air by convection QI 270.43 W Heat transfer rate of Insulation materials
