Hexsteel are important parts of the petrochemical industry FCCU overtemperature conditions due to the intensity of the problem caused by deformation, fracture, etc. drum package multiple failure prone, due to the harsh operating conditions, and therefore it is fully under the high temperature of the structural analysis has very important practical significance. Elastoplastic mechanics and thermodynamics analyze practical applications hexsteel, focuses on a heat distortion under hexsteel overtemperature conditions. Theory based on the finite element method, finite element model of the hexsteel With powerful finite element analysis software ANSYS hexsteel major operation stage temperature field analysis, while the border all constraints and boundary some constraints hexsteel The deformation of the situation to do the analysis and comparison. Come the the bulge deformation law of hexsteel overtemperature conditions. Including: (1) describes the current situation of the domestic research on the hexsteel cited the case of some domestic hexsteel damaged, damaged in hexsteel basis for the high temperature deformation of research on hexsteel stand title. (2) Research ANSYS finite element modeling of hexsteel research on thermal - structural analysis theory, simulation and the under hexsteel different geometry, load conditions, the preparation of pre-and post-processing program . (3) calculate the boundary constraints at 760 ° C, 800 ° C, 850 ° C, 880 ° C, 900 ° C overtemperature conditions hexsteel deformation, reached the the different area hexsteel deformation data and intends to aggregate formula. Example: ① When the solder joint off area in the range of 0.1 LT; S LT; about 0.3, the thickness of the z-direction in the hexsteel small amount of deformation, the deformation amount of about 5mm in the xy plane, substantially no deformation. (2) when the solder off an area of ??0.3 lt; and s lt; 0.6m ~ 2 in the direction of the thickness of hexsteel z significant deformation, deformation greater than 20 mm, distortion in the xy plane, about 2mm. ③ When the solder off an area of ??0.6 lt; s lt; 1m to 2, the deformation in the thickness z hexsteel direction, more than 30mm, the distortion in the xy plane, about 2mm. (4) the boundary under some constraints, at 760 ° C, 800 ° C, 850 ° C, 880 ° C, 900 ° C overtemperature conditions the deformation of hexsteel, respectively, obtained the different area hexsteel deformation data and intends to aggregate formula. For example: ① When solder shedding area in 0.15 LT; s LT; about 0.3m ~~ 2, in a thickness direction of the hexsteel a small amount of deformation, the deformation amount of about 4-6mm. ② When the solder off area in the 0.3 lt; s lt; 0.6 m2, the thickness z direction hexsteel significant deformation, deformation greater than 20-30mm distortion in the xy plane, about 2mm. (3) When the solder off an area of ??0.6 lt; s lt; 1m to 2 pm, in the thickness of hexsteel z direction deformation evident in the more than 30-40mm, distortion in the xy plane, about 2mm.
