At present, a lot of low chromium cast iron factories, mines and ports to use, high chromium cast iron liner is much higher than the hardness of the high manganese steel plate hardness. High chromium cast iron carbide eutectic hexagonal (CrFe) 7C3, hardness HRM501200-1800, higher than the average white iron eutectic carbides Fe3C3 (HRV50840-1100), while tempered by its basic organization, toughness than ordinary white cast iron greatly improved. At home and abroad for high chromium cast iron wear mechanism, fracture toughness, crack propagation mechanism, a series of studies, the results show that high chromium cast iron carbide can be adjusted to the size and shape, and the dispersion of the amount of secondary carbides and matrix organization (horse martensitic, austenitic, patenting) to adjust the performance to meet the requirements. In recent years, China has carried out a study of the relevant units of high chromium cast iron liner, the same conditions the wear resistance of up to 2 times of high manganese steel. But the toughness of these materials are thin and low alloy elements containing molybdenum, copper and other metal liner wear, higher production costs. Huanghua Port and Dalian-source environment limited liability company jointly developed a port of high chromium cast iron liner, and made good use of effects since the 1980s, the rapid development of China's iron and steel industry, continue to strengthen manufacturing operations, equipment operating rate The continuous improvement of liner wear spare parts made new demands. To this end, new materials, new technology is adopted. High chromium cast iron liners in the application of classification of spare parts, from the practical to consider the working conditions, wear material occurred in the relative motion between the abrasive and wear-resistant parts, under loads of metal wear-resistant composite liner, so Spare wear surface gradually from the mother, resulting in the continuous process of material losses, this process is related to many factors, but mostly lining spare parts at high temperatures, impact, abrasive wear conditions, the failure to make more complex factors, so the choice When the ingredients, when taking into account the abrasive itself changed little, should take into account the environmental track temperature range, the size and impact of abrasive abrasive form of liner. Based on the research and application of metal liner wear prices, as well as a variety of experimental data on the high chromium liner. Based on conditions in various prominent contradiction to choose, first determine the series and the appropriate upper and lower limits of chromium, select the secondary adjustment range of carbon and various alloying elements to obtain a more suitable overall performance, a reasonable choice ingredients to play The maximum potential liner.
