| titleOfInvention | Alloy ultra-high strength and toughness liner plate and preparation method during a kind of disintegrating machine is used |
| abstract | The present invention discloses alloy ultra-high strength and toughness liner plate and preparation method during a kind of disintegrating machine is used, and the percentage by weight of liner plate chemical composition is：C0.25%~0.45%；Si1.0%~1.5%；Cr0.5%~1.6%；Mn1.8%~2.2%；Mo0.3%~0.5%；B0.002%~0.004%；Nb0.03%~0.05%；Ti0.01%~0.03%；RE≤0.4%；Surplus is Fe and inevitable impurity, and the percent by volume of liner plate tissue is 50% ~ 55% lower bainite, 40% ~ 45% lath martensite and less than 5% retained austenite.Preparation method includes melting, casting, separation, heat treatment, and its case hardness of lining board of crusher of the present invention can reach 50~51HRC, and hardness is evenly distributed, and impact flexibility is in 100J/cm 2 ~300J/cm 2 , tensile strength reaches more than 1500MPa, reaches the requirement of unimach.Production technology is easy to operate, and uniform lower bainite and martensite heterogeneous structure are obtained in the range of larger cooling rate, it is ensured that have higher wearability, breaks through high manganese steel lining plate tradition, and cost has some superiority. |
