本文叙述了新型低合金耐蚀铸铁的试验研究工作。采用对比试验的方法,着重研究了该铸铁在各种溶液中的耐蚀性能。工业应用试验表明,新型低合金耐蚀铸铁用于硫酸泵叶轮,其使用寿命是灰铸铁 HT20-40的2～3倍。
This paper describes the experimental research work on a new type of low alloy corrosion resistant cast iron. Using the method of contrast test, the corrosion resistance of the cast iron in various solutions was studied emphatically. Industrial application tests show that the new low-alloy corrosion-resistant cast iron used in sulfuric acid pump impeller, the service life of cast iron HT20-40 is 2 to 3 times.
