目前，冶金轧辊的生产，特别是铸铁轧辊，为了提高其综合性能，采取不同的方法，其中复合铸铁轧辊是以冲洗法或半冲洗法置换辊芯铁水提高轧辊强度，或采用离心铸造方法。本发明克服了现有技术中的不足，提供一种合金铸铁与球墨铸铁复合的轧辊及其离心铸造与静态铸造的复合铸造 At present, metallurgical roll production, especially cast iron roll, in order to improve its overall performance, take a different approach, in which the composite cast iron roll is flushing method or semi-flushing method to replace the core of molten iron to increase the strength of the roll, or the use of centrifugal casting method. The invention overcomes the deficiencies in the prior art and provides a composite casting roll of alloy cast iron and nodular cast iron and composite casting of centrifugal casting and static casting
