高硅耐酸铸铁是含Si14—18%的Fe-Si-C合金,由于它具有耐蚀性能优良和价格低廉等特点,所以成为耐蚀合金领域中广泛使用的重要材料。但是,高硅铸铁对于高于室温的盐酸是不耐蚀的。本研究工作即是针对36%HCl,50℃温度的苛刻介质条件,研制一种抗热盐酸的含Mo高硅铸铁,同时,研究热处 High silicon acid-proof cast iron is Si-14-18% Fe-Si-C alloy, because of its excellent corrosion resistance and low cost, it has become a corrosion resistant alloy widely used in the field of important materials. However, high silicon cast iron is not corrosion resistant to hydrochloric acid above room temperature. This work is directed against the harsh media conditions of 36% HCl, 50 ℃ temperature, the development of a high temperature resistant hydrochloric acid containing Mo high silicon cast iron, at the same time, research heat
