钒对高铬铸铁耐热性的影响
EFFECT OF VANADIUM ON HEAT RESISTANCE OF HIGH CHROMIUM CAST IRON
-
摘要: 研究了高铬铸铁的抗高温氧化性能、耐激冷激热性,以及钒和各种合金元素对高铬铸铁耐热性能的影响。研究结果表明,钒对高铬铸铁的耐热性有着明显的不良影响。因此,必须严格控制用于冶金备件上的高铬铸铁中的钒含量。Abstract: The high temperature oxidation resistance and rapid cooling and heating resistance of high chromium cast iron,and effects of vanadium and various alloying elements on heat resistance of high chromium cast iron were investigated. The heat resistance of high chromium cast iron is adversely influenced by vanadium. Therefore, the vanadium content in high chromium cast iron used for metallurgical spare parts is seriously controlled.
