| Abstract: | A projection of advanced three times pouring two times compounding is used to resolve the technical problem of the low tensile strength in the compound layer and core of high chromium compound cast iron rolls. An advanced composition design is adopted. Tensile strength, fracture toughness and wear resistance of material are increased by effective modification for outer layer and middle layer material. High barrel hardness and low remnant austenite content are obtained successfully through quenching and twice tempering. |
