大型轧机组合式机架具有加工简单、成本低、易运输、上马快等优点,因此,近年国内很多钢厂引进中厚板轧机时都是选用组合式机架。为了对引进组合式机架进行技术消化,利用ANSYS对某组合式机架的紧固预紧力进行了仿真研究,给出螺栓承受的合适预紧力大小,为组合式机架的设计提供理论依据。 Large-scale rolling mill combined with a simple rack processing, low cost, easy to transport, quick start, etc., therefore, many domestic steel mills in recent years, the introduction of plate mill are the choice of modular racks. In order to digest the technology of the combined frame, the prestressing force of a combined frame is simulated by ANSYS, the suitable preload of the bolt is given, and the theory is provided for the design of the combined frame in accordance with.
