Mn13耐磨板生产的热处理应该注意什么?

生产Mn13耐磨板时应进行相关热处理,预热后锻造和加工,加工技术和用途也好。Mn13耐磨板进行热处理时,温度确实是技术性的工作,温度必须适当控制。
When producing Mn13 wear-resistant plate, relevant heat treatment should be carried out, forging and processing should be carried out after preheating, and the processing technology and application are good. During the heat treatment of Mn13 wear-resistant plate, the temperature is indeed a technical work, and the temperature must be properly controlled.
Mn13耐磨板的加热温度为810-830度,保温时间由炉子方式决定。回火温度:320度,时间充足,回火后油冷,减少回火脆性。处理是注意工件的变形,尽量有防变形的工具和淬火压回。
The heating temperature of Mn13 wear-resistant plate is 810-830 ℃, and the holding time is determined by the furnace mode. Tempering temperature: 320 ℃, enough time, oil cooling after tempering, reduce temper brittleness. Treatment is to pay attention to the deformation of the workpiece, try to have anti deformation tools and quenching press back.
Mn13耐磨板容易过热,所以要注意加热温度和保温时间。建议采暖820度,适当保温。回火温度:320度,时间充足。硬度:45-48HRC.性能好。盐浴NaCl:BaCl=3:7左右即可加热温度820,时间30秒/mm(mm指零件有效厚度),油冷。回火温度为280,空气炉时间为2小时,硝盐炉时间为30分钟。

Mn13耐磨板
Mn13 wear resistant plate is easy to overheat, so attention should be paid to heating temperature and holding time. It is suggested that the heating should be 820 ℃ and the temperature should be kept properly. Tempering temperature: 320 ℃, enough time. Hardness: 45-48hrc. Good performance. Salt bath NaCl: BaCl = 3:7, heating temperature 820, time 30s / mm (mm refers to the effective thickness of parts), oil cooling. The tempering temperature is 280, the air furnace time is 2 hours, and the nitrate furnace time is 30 minutes.
Mn13耐磨板耐磨层马氏体显微镜强度超过HVl700~2000左右,表层强度超过HRc58~62。Mn13耐磨板的耐磨层以钴合金为主,加上锰、钼、铌、镍等其他合金成分,合金成分中马氏体纤维分布,化学纤维方向与表层垂直。
The microscopic strength of martensite in the wear-resistant layer of Mn13 wear-resistant plate exceeds hvl700 ~ 2000, and the surface strength exceeds HRC 58 ~ 62. The wear-resistant layer of Mn13 wear-resistant plate is mainly composed of cobalt alloy, and other alloy components such as manganese, molybdenum, niobium, nickel, etc. the martensite fibers are distributed in the alloy components, and the direction of chemical fibers is perpendicular to the surface layer.
Mn13耐磨板显微镜强度是指硬质相的强度,但强度越高,耐磨性能越高。强度是Mn13耐磨板优良耐磨性能的基本,但强度和耐磨性能之间不是正比的关系,Mn13耐磨板经常耐磨,根本原因是有硬点,也有软点。
The microscope strength of Mn13 wear-resistant plate refers to the strength of hard phase, but the higher the strength is, the higher the wear resistance is. Strength is the basis of excellent wear resistance of Mn13 wear-resistant plate, but the relationship between strength and wear resistance is not proportional. Mn13 wear-resistant plate is often wear-resistant, the fundamental reason is that there are hard points and soft points.
一般来说,在破损的全过程中,有掉落的化学物质,该化学物质融入柔软的通常中,对表层不容易造成很大损害的通常机构的强度也很高的话,掉落的耐磨材料和其他化学物质,在相互健身运动中相互磨损,很快破坏了通常机构。
Generally speaking, in the whole process of damage, there are falling chemicals, which are integrated into the soft surface. If the strength of the mechanism is also very high, the falling wear-resistant materials and other chemicals will wear each other in the mutual fitness exercise, which will soon damage the common mechanism.
