Abstract:
TC4 alloy is widely used in engine. The method of forming is forging and mechanical process in the old days. With the complex profile of Titanium alloy, the process is quite difficult and lead to low ratio of qualified products. Therefore the method of hot rolling is chosen. According to the basic theory of hot rolling and applying the FEM simulation technology, the one symmetrical pass with different gauge between the two rollers is designed to obtain expected section with the complex profile. In order to restrict the rise of temperature basing on the characteristic of TC4 and make the flowing uniformly to meet the performance requirements, the optimum matching scheme of the pass with the roller is designed first, then the reasonable shape and dimension of the blank is determined, finally the three rolling passes of one blank rolled in one pass with different gauge is decided.
