| Abstract: | The change of steels used for welded pipe roll is analysed by comparing the properties. Manufacturing process and production cost of 45# steel with that of GCr15 steel. The feasibility of a new kind of double-metal roll, which is made by hardfacing a 45# steel core with anti-friction alloy, is probed. In order to produce a high anti-friction welded pipe roll with lower cost, an experiment based on the disscused ideal has been performed, and the double-metal rolls were tested in actural welded pipe production. |
