Research on Production of the Welded Pipe and Virtual Design and Manufacturing of Roll

The article introduced the method of the roller pass virtual design by computer simulation technology. It discussed that based on the virtual roller classification, the constructed roll pass design virtual manufacture system components model, the vertical roll three dimensional virtual charts and the engineering plat. It discussed distortion process in the straight seam welded pipe production and the virtual simulation of formation strength. Modeling technology about the roll virtual manufacture hardware environment and the system structure of roller virtual processing environment has researched.
