Abstract

The invention relates to a wear-resistant iron alloy material. The wear-resistant iron alloy material comprises the following components in percentage by weight: 32.5 percent of chromium, 5.8 percent of carbon, 2.5 percent of manganese, 1.1 percent of tungsten, 0.3 percent of titanium, 0.1 percent of molybdenum, 0.35 percent of vanadium, 0.12 percent of boron, 0.05 percent of niobium, 0.01 percent of zirconium, 0.001 percent of lanthanum and the balance of iron.

Description

A kind of wear-resisting ferroalloy materials

Technical field

The invention belongs to metal material field, specifically refer to a kind of ferroalloy materials of surface abrasion resistance.

Background technology

The ferroalloy materials that comprises carbide has been widely used as the consumptive material of upper surface of substrate hardfacing overlay for many years.Can in this mixture, add other ferroalloy powdeies, for example molybdenum-iron, ferrovanadium, ferro-niobium, ferro-boron and ferrotianium, with thinking that molten bath and the hard-facing layer forming give different material behaviors.

But the chromium of higher price is to maximize the carbon content in surfacing layer cladding.Because in the relatively short arc-melting time, be generally in 2 to 5 seconds, uncombined carbon is difficult in molten metal bath dissolving to form suprabasil hard-facing overlay, thereby in iron alloy mixture, to add uncombined carbon powder be invalid in order to the carbon content increasing in final surfacing layer cladding.

Summary of the invention

The object of this invention is to provide a kind of method of producing improved hard-facing overlay with respect to prior art in cost-effective mode.

The present invention is achieved by the following technical solutions:

A kind of wear-resisting ferroalloy materials, its composition is by weight percentage, 32.5% chromium, 5.8% carbon, 2.5% manganese, 1.1% tungsten, 0.3% titanium, 0.1% molybdenum, 0.35% vanadium, 0.12% boron, 0.05% niobium, 0.01% zirconium, 0.001% lanthanum and the iron of surplus.

The invention has the beneficial effects as follows:

According to the present invention, provide the hard-facing of producing by aforesaid method overlay in suitable substrates.

Embodiment

This wear-resisting ferroalloy materials is for hard-facing, and its production method is:

Formation has the even melting material of the key element such as carbon and chromium of desired concn, for the iron alloy welding consumptive material that comprises chromium carbide; It consists of, be by weight percentage 32.5% chromium, 5.8% carbon, 2.5% manganese, 1.1% tungsten, 0.3% titanium, 0.1% molybdenum, 0.35% vanadium, 0.12% boron, 0.05% niobium, 0.01% zirconium, 0.001% lanthanum and the iron of surplus;

Formed the iron alloy that the comprises chromium carbide welding consumptive material of solid by above-mentioned melting material;

Wherein manganese, tungsten, molybdenum, vanadium, niobium, zirconium and lanthanum are all to form uniform melting material in the mode of monomer iron alloy;

Degassed by carrying out after 150 to 220 degree of at the uniform velocity lowering the temperature after needing to be incubated 30 to 60 minutes after above-mentioned melting material fusing.

Claims

1. a wear-resisting ferroalloy materials, it is characterized in that: its composition is by weight percentage 32.5% chromium, 5.8% carbon, 2.5% manganese, 1.1% tungsten, 0.3% titanium, 0.1% molybdenum, 0.35% vanadium, 0.12% boron, 0.05% niobium, 0.01% zirconium, 0.001% lanthanum and the iron of surplus.
