Hot Rolling Coiler Key Component Finite Element Analysis And Dynamics Research

The coiler took the hot company rolls over on the production line the important supporting facility, is responsible for the strip volume which comes out the rolling take the volume, the coiler working condition is affecting to a great extent the entire production line operation.The 2300 mm hot company rolls over the down coiler to take one kind of new coiler, has the big tensity, the big volume diameter, the volume takes the strip width and thickness is big and so on the characteristics.Simultaneously the reel axis and the quadrant and so on the key component distortion degree as well as the breakage or not is affecting the coiler active status directly, therefore carries on the finite element analysis as well as the modality research to these key components has certain significance as well as the actual value.The present paper by thermodynamics and the finite element analysis theory underlie, and unifies the actual situation, obtains parameter as well as size which needs, finite element analysis software has carried on the finite element simulation using ANSYS the WORKBENCH to the hot rolling coiler key component, has conducted the key research to the quadrant thermosetting coupling phenomenon, has carried on the modality analysis to the reel axis, and found the question according to the analysis result which needs to pay attention in the practical work process, confirmed the hot rolling coiler key component to be possible in the actual production the normal work, for further studied the coiler the equipment performance to provide the reference data.First to the coiler structure, the application, the classification, the work process as well as the domestic and foreign production present situation carries on the description, enumerates the domestic some scholars in all quarters the research which makes facing the coiler, and makes the simple summary to this article research content.To the heat expansion theory, the heat transfer theory, the thermo-elasticity theory as well as the ANSYS thermal deformation analysis basic principle carries on the simple introduction, provides the rationale for later stable state thermal analysis as well as the thermal-stress analysis.Next, because the quadrant can appear certain degree in the work process the breakage, the break, in order to discover the quadrant in the work time easy to damage the place, constructs the quadrant the three dimensional three-dimensional model, carries on the structure static analysis separately using the ANSYS software to the quadrant, the stable state thermal analysis as well as the thermal-stress analysis, the obtained data after the thermosetting coupling, carries on to its result the research.Discovers after the thermal load and the structural stress superimposition stress concentration region as well as the biggest distortion place, had determined easy to appear the crack or the damage position, has provided the reference data for the practical work maintenance of equipment.Finally, in order to avoid the reel axis takes when the volume having resonating, has constructed the reel axis three dimensional three-dimensional model, carries on the modality analysis to the reel axis, has analyzed the reel axis inspires and the distortion data under the free state as well as the restraint condition first ten steps, and the reel axis modality carries on the contrast to two conditions under, obtains its biggest operating frequency, takes the axis after the confirmation volume not to be able to appear the resonance effect.
