摘要
采用电渣熔炼、卧式离心铸造和顶注填芯法相结合浇注离心复合铸铁轧辊的生产工艺,解决了产品在复合浇注过程中所产生的裂纹问题。通过改进离心电渣熔铸双基复合轧辊生产工艺参数,使离心电渣熔铸双基复合轧辊能批量生产。结果表明,产品的质量和性能满足轧辊的技术指标,比常规辊轧制能力提高30%~50%。
The production process of centrifugal composite cast iron roller was combined with electroslag smelting,horizontal centrifugal casting and top filling core method to solve the crack problem during the compound pouring process.The production process parameters of the double-base composite roll were improved by improving the centrifugal electroslag casting,and the centrifugal electroslag casting double-base composite roll can be mass produced.The results show that the quality and performance of the product meet the technical index of roll,which is 30%-50% higher than the conventional roll rolling ability.
