Abstract
The invention discloses a boron-containing iron-based wear-resistant material. The boron-containing iron-based wear-resistant material comprises the following element ingredients in percentage by weight: 0.35-0.55% of C, 0.5-1.0% of Si, 5-15% of Mn, less than 0.04% of P, less than 0.04% of S, 1.5-2.0% of Ni, 0.10-1.00% of B, 0.3-0.5% of V, 1.0-2.0% of Cu, 0.8-1.5% of Mo, and the balance of Fe. The boron-containing iron-based wear-resistant material disclosed by the invention is improved in wear resistance, tensile strength and impact toughness, and reduced in production cost.
Description
Technical field
The present invention relates to metallic substance, relate in particular to a kind of boracic ferrio wear-resistant material.
Background technology
Traditional metal wear resistant material can be divided into following a few class, and a class is to be used under thump, the big pressure load condition as tup, jaw, Zha Jiubi, broken wall etc., generally selects high mangaenese steel for use.Another kind of is to be used under the low impact load as grinding machine fine grinding storehouse liner plate, abrading-ball etc., generally selects antifriction cast iron for use.And between the medium impact between the two load as grinding machine one storehouse liner plate etc., if it is not select high mangaenese steel for use, because the impact load deficiency can't make the surface fully harden, wear-resisting on the contrary.Can't stand than HI high impact and hold with antifriction cast iron, generally adopt steel alloy.Because wear-resistant hard is less relatively in the middle and high steel alloy, does not then have wear-resistant hard phase in the low-carbon alloy steel, the wear resistance of steel alloy is generally relatively poor.At the deficiency that existing high-abrasive material exists, need a kind of wear resistance of exploitation to be better than wearable cast steel commonly used, and intensity and toughness are better than antifriction cast iron, and have the boracic ferrio wear-resistant material than lower production cost.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can improve wear resistance, tensile strength and impelling strength, the boracic ferrio wear-resistant material that reduces production costs.
The present invention is achieved in that a kind of boracic ferrio wear-resistant material, it is characterized in that: each elemental composition is by weight percentage: C:0.35～0.55%; Si:0.5～1.0%; Mn:5～15%; P＜0.04%, S＜0.04% Ni:1.5%～2.0%; B:0.10%～1.00%; V:0.3 ~ 0.5%; Cu:1.0%～2.0%; Mo:0.8 ~ 1.5%, all the other are Fe.
The present invention has improved wear resistance, tensile strength and the impelling strength of material, has reduced production cost.
Embodiment
A kind of boracic ferrio wear-resistant material is characterized in that: each elemental composition is by weight percentage: C:0.35～0.55%; Si:0.5～1.0%; Mn:5～15%; P＜0.04%, S＜0.04% Ni:1.5%～2.0%; B:0.10%～1.00%; V:0.3 ~ 0.5%; Cu:1.0%～2.0%; Mo:0.8 ~ 1.5%, all the other are Fe.During concrete enforcement; the present invention is that utilization contains chromium high mangaenese steel waste material, low-carbon waste steel is main raw material; add ferro-boron, ferrotianium, rare earth ferrosilicon and aluminium in addition; have that raw material sources are abundant, production technique is easy and advantage such as over-all properties height, thereby realize large-scale production and the industrial applications of boracic ferrio wear-resistant material.Make performance and the result of use of homemade ball grinding machine lining board reach international like product advanced level, and the work-ing life of improving ball mill greatly.Because not adding alloying elements such as expensive tungsten, molybdenum, nickel, vanadium, niobium, low production cost; Its matrix is made up of martensite, austenite and bainite, and obdurability is good, is distributed with 12～16% high rigidity boride on the matrix, so the material hardness height, reaches 57～60HRC, and impelling strength reaches 25～28J/cm
2, tensile strength reaches 870～950Mpa; Has excellent abrasive, for the manufacture of ball grinding machine lining board, grinder hammerhead and ball mills, improve 200～250% than high manganese steel lining plate work-ing life respectively, improve 120～160% than steel alloy tup, abrading-ball ball loss-rate low-chromium cast-iron grinding ball reduces by 55～70%, improve ball mill and crusher work-ing life, reduce the broken cost of material, have remarkable economical and social benefit.The present invention is widely used in the first-class occasion of ball grinding machine lining board, abrading-ball and crusher hammer of industries such as metallurgy, mine, building materials and electric power.Consumption is huge both at home and abroad, only consumes nearly 3,000,000 tons in domestic year, is worth more than 2,500,000 yuan.
