一、前言用离心法生产复合铸铁轧辊(如线材轧机轧辊、板材热连轧机精轧机组工作辊等等),不仅合金材料消耗少、生产成本低,而且轧辊使用寿命显著提高。在国外已成功地采用离心法生产轧辊,国内也正在试生产。轧辊离心铸造的工艺方式按轧辊模具回转轴线在空间的位置不同,分立式(垂直轴线)、倾斜式(倾斜轴线)、卧式(水平轴 I. Preface Production of composite cast iron rolls by centrifugal method (such as wire rod mill, work roll of finishing mill of hot strip mill, etc.) not only consumes less alloy material, but also has lower production cost and significantly improves roll service life. In foreign countries have successfully used centrifugal production roll, the country is also trial production. Roll centrifugal casting process according to the axis of rotation of the roll mold in space in different locations, discrete (vertical axis), tilt (tilt axis), horizontal (horizontal axis
