The invention discloses a high toughness wear-resistant steel. The weight percentage of the alloy consists of carbon 0.3-0.5%, silicon 0.6-0.8%, tungsten 0.9-1.2%, chromium 2.9-3.9%, titanium 1.2-1.8%, manganese 2-4%, molybdenum 0.9-1.2%, sulfur 0.02-0.04%, and iron. The invention has the following beneficial effects: since the content of carbon is reasonably limited and the proportion between chromium, nickel and carbon is specifically limited, and at the same time, other material components with appropriate proportion are selected, the protective plate produced by the method has very good toughness and, more importantly, good hardness, so that it has wear resistance and resistance. The impact and other properties meet all the requirements of mechanical properties in shot blasting process, prolong the service life, improve the microstructure and properties of the alloy by rapid cooling and reasonable quenching process, have good impact toughness and comprehensive mechanical properties, and make the products meet the requirements of wear resistance and moderate impact performance.
【技术实现步骤摘要】
一种高韧性耐磨钢
本专利技术涉及一种抛丸室用护板钢材,特别是一种高韧性耐磨钢。
技术介绍
抛丸机是利用高速旋转的抛丸器将弹丸高速喷出,使弹丸具有一定的动能,高速直线运动的弹丸直接冲击在工件表面上,以清除工件表面的锈迹,但是抛丸机在进行抛丸的过程中会有弹丸绕过工件打在抛丸机的室体内,时间久了高速的弹丸会将室体打穿,因此现有技术中常常在抛丸机室体内铺设护板,现有的护板种类比较多,一般采用高铬铸铁或锰钢板,但是在面临着高速喷射的弹丸,现有的护板由于材料问题使其的强度仍然不够好,使用寿命不长,因此使用一段时间后就要将其更换,由此不但造成成本上的浪费而且耽误工期,影响生产效率。
技术实现思路
本专利技术要解决的技术问题是提供一种耐磨性好、抗冲击能力强且使用寿命长的高韧性耐磨钢。为了解决上述技术问题,本专利技术的高韧性耐磨钢,其重量百分比的合金成分为:碳0.3~0.5%,硅0.6~0.8%,钨0.9~1.2%,铬2.9~3.9%,钛1.2~1.8%,锰2~4%,钼0.9~1.2%,硫0.02~0.04%,余量为铁。碳0.4%,硅0.7%,钨1.1%,铬3.5%,钛1.6%,锰3%,钼1.1%,硫0.03%,余量为铁。一种上述的高韧性耐磨钢的处理工艺,包括以下步骤:A、采用常温入炉,将铸造件加热到870~890℃,保温55~75分钟,然后升温至990~1030摄氏度保温80~110分钟,之后快速水冷;B、将铸造件加热至680~700℃再进行淬火,淬火后及时进行回火,回火温度为310~340℃。和现有技术相比,本专利技术具有以下有益效果:由于合理限定了碳的含量以及具体限定了铬 ...
