Abstract
The invention discloses a preparation method of wear-resistant bucket teeth for a loader. Raw materials including, in weight percent, 2.2-2.5% of C, 8.5-11% of V, 5-6.5% of Cr, 2-3% of Ni, 0.8-1.1% of Mn, 0.5-1% of W, 0.6-0.8% of Si, less than or equal to 0.03% of impurities P, less than or equal to 0.02% of impurities S and the balance Fe are smelted and cast to obtain the wear-resistant bucket teeth. The wear-resistant bucket teeth prepared by the method have fine hardness and toughness and excellent wear resistance.
Description
Technical field
The present invention relates to a kind of preparation method of shovel loader wear-resistant bucket tooth.
Background technology
Shovel loader is one of engineering machinery main in earthwork, and bucket tooth is one of frayed more serious part on shovel loader, in use not only to be subject to the strong wear of the abrasive particles such as sandstone, but also the intense impact of large stone will be subject to, therefore, when select materials, need hardness and the toughness of considering material, to reduce wearing and tearing and the fracture of material.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of shovel loader wear-resistant bucket tooth.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of preparation method of shovel loader wear-resistant bucket tooth, the raw material of consumption obtains described wear-resistant bucket tooth through melting, casting as following weight percent: C 2.2 ~ 2.5%, V 8.5 ~ 11%, Cr 5 ~ 6.5%, Ni 2 ~ 3%, Mn 0.8 ~ 1.1%, W 0.5 ~ 1%, Si 0.6 ~ 0.8%, surplus is Fe, wherein, impurity P≤0.03%, impurity S≤0.02%.
Further, the weight percent consumption of described raw material is as follows: C 2.3 ~ 2.5%, V 8.5 ~ 11%, Cr 6 ~ 6.5%, Ni 2.5 ~ 3%, Mn 1 ~ 1.1%, W 0.8 ~ 1%, Si 0.7 ~ 0.8%, surplus is Fe, impurity P≤0.03%, impurity S≤0.02%.
Compared with the wear-resistant bucket tooth of existing loading shovel, wear-resistant bucket tooth prepared by the inventive method can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of bucket tooth.
