Study On Rolling Of â… -beam And Its Edge Profile

The article mainly study on rolling of I-beam and its edge profile, theuniversal rolling law is the main principle of the process. In universal rollingmethod, two horizontal roll shape I-beam cross section of the book sizes, verticalroll shape the side of the profile. In order to roll a variety of specifications ofnon-slip flat steel, Horizontal roll consist of the roll core and roll ring. Thenon-slip flat steel is done with two universal rolling pass.Some problems exist in the current process plan: edge tooth filling isincomplete; Tooth roots have flash and the ring of the horizontal roll cracksfrequently. So this article will combine deform software Simulation and Experimentto explore and solve these problems.First, the article is based on the Theory of extrusion forming, study on howthe tooth inclination, The spacing between the teeth, and the diameter of thevertical roll affect the quality of tooth forming, it provides a guide on designingvertical roll which is the mold of tooth shape. And then in foundation of the theoryof rolling spread, the article explore how the reduction of the width of the websand the height of the wing plate affect the quality of tooth forming, it providesa basis on designing for the first rolling. While the paper guide the design of thisexperiment by some conclusions.In process of analyzing the simulation of rolling process, the article find thereason of generation of flash and broken of the ring, and to verify this reason byexperiment, at last the article solve them by improving the method of the currentprocess.To simplify the process, This article have a try to shape the non-slip flat steelby rolling only one time in combination of simulation and experiments. I find thatthe idea is feasible...
