Abstract

The invention discloses a preparation method for a high-hardness manganese-iron alloy material. The preparation method comprises the following steps: S1, Fe is added into a smelting furnace and is heated to be completely melted; S2, Mn, Cr, Zr, Mo, Cd, W, V, graphite, diamond, WC, Cr2B, La2O3, Nd(OH)3, Eu2O3,Yb2O3, PrCl3, PrSi2, YSi2 and TbN are added into the Fe melted in the S1, and are uniformly mixed with the melted Fe to obtain an alloy melt; S3, the alloy melt in the S2 is refined, and a refining agent is added in the refining process; S4, the alloy melt refined in the S3 is cast to obtain a casting; and S5, the casting cooled in the S4 is tempered and cooled to obtain the alloy material. According to the preparation method for the high-hardness manganese-iron alloy material, by adding Cr and rare earth elements, the manganese-iron alloy is high in strength and good in toughness and wear resistance, and the comprehensive performance of the copper alloy is greatly improved.

Description

technical field [0001] The invention relates to the field of manufacturing metal alloy materials, more specifically, the invention relates to a method for preparing high-hardness ferromanganese alloy materials. Background technique [0002] Fe-based alloy materials have been widely used in petroleum, machinery, chemical and other industries due to their low raw material cost, easy processing and manufacturing, convenient storage and transportation at room temperature, and excellent mechanical properties, and have become a current research hotspot. However, due to insufficient hardenability and toughness of iron, low hardness, poor wear resistance, and large friction coefficient, the core of the casting has poor wear resistance or early fracture and short service life. Therefore, there is an urgent need for a Fe-based alloy material with high hardness and high impact toughness to meet the actual demand. Contents of the invention [0003] It is an object of the present inve...
