Since the 1980s, the rapid development of China's steel industry, continue to strengthen manufacturing operations, equipment operating rate continues to improve, spare parts for wear liner 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 liner wear parts, the external force, so spares resistance grinding 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, so that the failure of the price factor is more complex liner wear, Therefore, the choice of 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 high chromium liner and applied research, as well as a variety of experimental data. 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. High wear-resistant composite steel price-performance ratio, although the manufacturing costs, but increase the service life several times, making maintenance costs and downtime greatly reduced, its price performance ratio than ordinary material about 2 to 4 times. Material handling capacity, the more severe equipment wear factories, wear-resistant composite plate using economic effect is more obvious. Good heat resistance: resistant layer is recommended to use high-quality liner wear at ≤600 ℃ conditions, the inclusion of vanadium resistant liner models, molybdenum alloy in the alloy layer can withstand the high temperatures ≤800 ℃ wear. Recommended temperature as follows: Ordinary carbon steel substrate is recommended to use not more than 380 ℃ conditions; low-alloy heat-resistant steel (15CrMo, 12Cr1MoV etc.) board recommended the use of not more than 540 ℃ conditions; resistant stainless steel substrate is not higher than recommended 800 ℃ condition to use.
