Abstract
The invention discloses a preparation method of a wear-resisting steel main cutting board for a loader; the wear-resisting steel main cutting board is prepared by smelting the following raw materials by the weight percentage: 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 W, 0.6-0.8% of Si, and the balance Fe, wherein the content of an impurity P is not more than 0.03%, and the content of an impurity S is not more than 0.02%. The wear-resisting steel main cutting board prepared by the method has good hardness and toughness and excellent wear resistance.
Description
Technical field
The present invention relates to the preparation method of a kind of shovel loader wear resisting steel operator plate.
Background technology
Shovel loader is one of engineering machinery main in earthwork, wearing and tearing are one of major ways causing this kind of machinery operator blackboard newspaper useless, 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 the preparation method of a kind of shovel loader wear resisting steel operator plate.
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 resisting steel operator plate, the raw material melting of consumption as following weight percent obtains the operator of described wear resisting steel plate: C 2.2 ~ 2.5%, V 8.5 ~ 11%, Cr 5 ~ 6.5%, Ni 2 ~ 3%, W 0.8 ~ 1.1%, 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%, W 1 ~ 1.1%, Si 0.7 ~ 0.8%, and surplus is Fe, impurity P≤0.03%, impurity S≤0.02%.
Operate compared with plate with the wear resisting steel of existing shovel loader, wear resisting steel operator plate prepared by the inventive method can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of knife plate.
