Abstract
The invention discloses a preparation method of a wear-resistant steel bottom plate 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, 0.6-0.8% 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 to obtain the wear-resistant steel bottom plate. The wear-resistant steel bottom plate prepared by the method has 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 resisting steel base 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 power shovel bottom sheet to scrap, 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 preparation method of shovel loader wear resisting steel base 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 base plate, the raw material melting of consumption as following weight percent obtains described wear resisting steel base plate: C 2.2 ~ 2.5%, V 8.5 ~ 11%, Cr 5 ~ 6.5%, Ni 2 ~ 3%, Mn 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%, Mn 1 ~ 1.1%, Si 0.7 ~ 0.8%, and surplus is Fe, impurity P≤0.03%, impurity S≤0.02%.
Compared with the wear resisting steel base plate of existing loading shovel, wear resisting steel base plate prepared by the inventive method can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of base plate.
