【摘要】 介绍了铸铁法兰管连续铸造的新工艺方法和所采用的日本耐酸铸铁管的化学成分，经两年多的研制和拉管试验，终于试制成功了耐高温浓硫酸腐蚀的连铸低铬铸铁法兰管。同时，还探讨了不同的含铬量对拉管生产操作过程中工艺参数的影响。更多还原

【Abstract】 This paper describes the advantages and manufacturing method of continuous casting cast iron flange pipe and the chemical constitution provided by Japan acid proof cast iron pipe standard. After more than two years study and pull pipe test.A continuous casting low chrome cast iron flange pipe of high temperaturestrange sulfuric acid corrosion resistant has been successful trial produced. And same time, we also explore the influence of technological parameter with difference chrome content to the pull pipe operation process.更多还原
