摘要
通过试验可知：ＲＨＳ—３耐蚀铸造合金在温度为７０～２２０℃、浓度为９８％浓硫酸中腐蚀率为０１ｍｍ／ａ左右，且可以铸造和焊接。同时研制的ＲＡＣＩ—１耐蚀铸铁也具有良好的耐蚀性。用上述合金和铸铁试制出的泵件经现场使用一年左右均无明显腐蚀。
Abstract Experimental test showed that RH-3 cast alloy had a corrosion rate of about 0 1 mm/a in 98% H 2SO 4 at 70～220℃ and satisfactory casting and welding properties,and RACI-1 cast iron also had good corrosion resistance One year of field application indicated that no detectable corrosion occured to the pump components made of the cast alloy and iron
