Example Embodiment

[0032] The mass percentage of the chemical composition of the high boron wear-resistant alloy material of the present invention is: C: 0.4--0.5%, B: 2.0--2.5%, Si: ≤1.5%, Mn: 0.8--1.5%, Cr: 0.6--0.8 %, Mo: 0.1--0.3%, Ti: 0.5--1.0%, S: ≤0.04%, P: ≤0.04%, and the balance is iron. Among them, silicon element comes from scrap steel.

[0033] In the present invention, each element is as follows:

[0034] C: Carbon is very important to the structure and performance of high-boron composite wear-resistant alloy materials. It is mainly dissolved in the matrix to play a role in solid solution strengthening, and can also promote the transformation of matrix martensite, improving the matrix of composite wear-resistant alloy materials. hardenability. If the carbon content is too high, it will increase the brittleness of the matrix material, and if it is too low, it will affect the hardenability of the matrix and reduce its wear resistance. Therefore, the C content should be controlled b...

Abstract

The invention relates to the field of abrasion resistant materials, in particular to a high-boron, iron-based and abrasion-resistant alloy material and a production method thereof. The high-boron, iron-based and abrasion-resistant alloy material is composed of, by mass, 0.4-0.5% of C, 2.0-2.5% of B, lower than or equal to 1.5% of Si, 0.8-1.5% of Mn, 0.6-0.8% of Cr, 0.1-0.3% of Mo, 0.5-1.0% of Ti, lower than or equal to 0.04% of S, lower than or equal to 0.04% of P and the balance Fe. By means of the production method, an electromagnetic stirrer is omitted, and the cost of the production process is low; the cost of the modification treatment technology is low, and the modification treatment method is simple. The defects that Fe2B in an existing high-boron and abrasion-resistant alloy material is of a net form, and the number of particles of the net form needs to be decreased by prolonging the reservation time of high temperature or adopting electromagnetic mixing in heat treatment are overcome. The roughness and performance reliability of the high-boron, iron-based and abrasion-resistant alloy material are improved, and the overall use performance is further improved.

Description

technical field [0001] The invention relates to the field of wear-resistant materials, in particular to a high-boron iron-based wear-resistant alloy material and a production method thereof. Background technique [0002] At present, in the field of wear-resistant materials, wear-resistant materials with martensite or bainite matrix structure or third-generation wear-resistant materials with particle-reinforced phases in addition to martensite, bainite or retained austenite matrix are mostly used. Abrasive material - high chromium cast iron develops wear-resistant parts, because there is a high hardness reinforcing phase Cr in high chromium cast iron 7 C 3 , its carbide microhardness has reached HV1300~1600, so its performance has been greatly improved compared with the previous two generations of wear-resistant materials - white cast iron and high manganese steel, and its hardness can reach HRC60~65, but due to its carbide It is usually long and thick, so its impact toughn...
