摘　　要：介绍了合金半钢轧辊的生产试制情况,采用静态浇注生产方式,通过对化学成分、热处理工艺、造型、熔炼、浇注、加工等生产工序的控制,并将工艺设计阶段预计措施实施在相应生产工序中,有效防止上下辊颈变形与缩松质量缺陷,制造出合格的合金半钢轧辊。The trial production of alloy semi-steel roll has been introduced. The static pouring production mode has been adopted. Though the control of the chemical composition, heat treatment process, molding, melting, pouring, processing and other production processes, the estimated measures in the process design stage have been implemented in the corresponding production process, which effectively prevents the neck deformation of the upper and lower rolls and shrinkage loose quality defects. Finally, the qualified alloy semi-steel roll has been manufactured.
