Abstract
The invention discloses a wear-resistant steel bottom plate for a loader, which comprises the following chemical components in percentage by weight: 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 P, less than or equal to 0.02% of S, and the balance of Fe. The wear-resistant steel bottom plate has good hardness and toughness and excellent wear resistance.
Description
Technical Field
The invention relates to a wear-resistant steel bottom plate for a loader.
Background
The loader is one of the main construction machines in the earth moving engineering, the abrasion is one of the main modes causing the scrapping of the bottom plate of the bucket of the machine, the loader is strongly abraded by abrasive grains such as sand and stone and is also strongly impacted by large stone blocks during the use process, and therefore, when the material is selected, the hardness and the toughness of the material need to be considered so as to reduce the abrasion and the fracture of the material.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a wear-resistant steel bottom plate for a loader.
In order to solve the technical problems, the invention provides the following technical scheme: a wear-resistant steel bottom plate for a loader comprises the following chemical components in percentage by weight: 2.2 to 2.5 percent of C, 8.5 to 11 percent of V, 5 to 6.5 percent of Cr, 2 to 3 percent of Ni, 0.8 to 1.1 percent of Mn, 0.6 to 0.8 percent of Si, less than or equal to 0.03 percent of P, less than or equal to 0.02 percent of S, and the balance of Fe.
Further, the wear-resistant steel bottom plate comprises the following chemical components in percentage by weight: 2.3 to 2.5 percent of C, 8.5 to 11 percent of V, 6 to 6.5 percent of Cr, 2.5 to 3 percent of Ni, 1 to 1.1 percent of Mn, 0.7 to 0.8 percent of Si, less than or equal to 0.03 percent of P, less than or equal to 0.02 percent of S, and the balance of Fe.
Compared with the wear-resistant steel bottom plate for the bucket of the existing loader, the wear-resistant steel bottom plate can obviously improve the hardness and toughness of materials and reduce the wear of the bottom plate.
Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is in no way intended to limit the invention.
Example 1

Example 3
A wear-resistant steel bottom plate for a loader comprises the following chemical components in percentage by weight: 2.5% of C, 11% of V, 6.5% of Cr, 3% of Ni, 1% of Mn, 0.8% of Si and the balance of Fe. And (3) charging and smelting according to the proportion to obtain the wear-resistant steel bottom plate.
Phosphorus and sulfur are inevitable impurities, and P and S in the final product are controlled to be less than or equal to 0.03 percent and less than or equal to 0.02 percent.
The hardness of the wear-resistant steel bottom plate is 70.6HRC, and the impact toughness is 51J/cm 2.
