【摘要】 本文针对风扇磨煤粉碎机锤头的磨损特征,应用含15％Cr及3.2～3.6％C的高铬白口铸铁取代普通白口铸铁,使锤头的抗磨能力提高了6.4倍,从而降低了磨煤的生产成本,提高了磨煤质量和生产效率。更多还原

【Abstract】 This paper is aimed at the wear and tear characteristics of fan-mill coal pulverizer hammer. If high chromium white iron at 15% Cr, 3.2- 3.6% C is applied to substitute for common white iron, the wearability of hammer head is increased for 6.4 times so that the cost of producting mill coal can he decreased and the quality and productivity of the mill coal can be increased.更多还原
