Abstract
The invention discloses a high-strength wear-resisting alloy and a preparation method thereof. In order to reduce the cost of raw materials, the alloy is not doped with niobium, vanadium, nickel and other metal elements, and comprises the raw materials of, by weight, 0.3-0.6% of Mo, 1.5-2% of Mn, 0.2-0.5% of Ti, 0.3-0.6% of Cr, and 97-97% of steel billet. The preparation method mainly includes steps of: placing qualified steel billets in a steelmaking furnace ladle for melting; successively adding a certain percentage of Mo, Mn, Ti and Cr; smelting for 5 to 15 minutes; conducting a secondary tempering treatment in the smelting process; and carrying out a heat treatment after alloy molten steel casting. The alloy has refining grain, and tensile strength and yield both above 400MPa, and can be widely used in fields of machinery, metallurgy, mining, petroleum and electricity, etc.
Description
Technical field:
What the present invention relates to is metallurgical material manufacturing technology field, especially relates to making a kind of high-strength wearable alloy material and production technique thereof.
Background technology:
The alloy material kind that is applied to fields such as mine, generating, building materials, oil, machinery, chemical industry at present is more; With iron and steel is main, and the high-strength wearable performance is not fine, part kind alloy is also arranged in order to reach in its wear-resisting high-strength; In alloy melting, mix metallic elements such as niobium, vanadium, nickel; Improve raw materials cost, consumed scarce resource, uneconomical economically.
Summary of the invention:
The objective of the invention is to provide a kind of HS attrition resistant again alloy material to the deficiency of prior art, and the industrial production process of this material.It is low to have a production cost with the mechanical means component of alloy material preparation, long service life, and more than the tensile strength 450MPa, more than the ys 400MPa, advantage such as suitable application area is wide, and is good in economic efficiency.
1, a kind of high-strength wearable alloy is characterized in that the weight percent of its feed composition is:
2, a kind of high-strength wearable alloy according to claim 1 is characterized in that: the steel billet material
3, a kind of method for preparing the high-strength wearable alloy of claim 1-2 is characterized in that: will meet earlier
4, the method for the high-strength wearable alloy of preparation claim 1-2 as claimed in claim 3 is characterized in that: in melting
The invention has the beneficial effects as follows:
(1) do not mix metallic elements such as expensive niobium, vanadium, nickel, make this high-strength wear-resistant alloy raw materials cost lower;
(2) production technique is comparatively simple, and secondary ladle molten steel hardening and tempering process is held easily;
(3) this metal grain refinement, metallograph show that atom combines closely in the alloy crystal, and crystal grain is less, just because of this reason can make alloy reach HS and attrition resistant effect.
(4) this alloy wear-resisting effect is superior to berylliumbronze.
Embodiment:
The per-cent of getting Chemical Composition weight is: the steel billet materials of C element 0.2-3.5%, Si element 0.6-1.6%, P element≤0.04%, S element≤0.04%, Fe element 93-98% is put into the steel melting furnace ladle; Be heated to alloy melting; The Mo, Mn, Ti, the Cr metal that divide order to add certain ratio to the boiling back, melting 5-15 minute.Because of the pure more price of metal is high more, so when adding Mo, Mn, Ti, Cr metal, can add its iron alloy.Before casting was burnt in tapping, it was that Mo accounts for 0.3-0.6%, Mn and accounts for that 1.5-2%, Ti account for 0.2-0.5%, Cr accounts for 0.3-0.6% that the stokehold chemical examination makes in this alloy liquid above-mentioned metallic element ratio, and C, S, P element are up to standard; If each element is nonconforming; Carry out modifier treatment, secondary is modified to get final product, and the alloy liquid tapping is burnt casting in the mould of component shape; Suitably heat-treat after the cooling, carry out anti-corrosive treatment again after the surface finish finishing.After be delivered for use.
Claims (4)
1. high-strength wearable alloy, it is characterized in that the weight percent of its feed composition is: Fe accounts for 98%.
2. a kind of high-strength wearable alloy according to claim 1 is characterized in that: in the steel billet material, C, P, S are arranged in the chemical element composition.
3. a method for preparing the high-strength wearable alloy of claim 1-2 is characterized in that: earlier raw material is put in the stove.
4. the method for the high-strength wearable alloy of preparation claim 1-2 as claimed in claim 3 is characterized in that: in fusion process, will add other element, processing under cooling.
