Abstract
The antiwear alloy cast iron resisting impact fatigue is produced by adding waste steel and Si, Mn elements to pig iron or iron alloy smelted with waste Cr-V-Ti slag, Ni slag and W slag through modification and strong toughening, and may be used to manufacture grinding balls and bar, hammer and lining. The times of impact fatigue are greater than 15 thousands and hardness is HRC 46-63 with a breaking rate less than 1%. It has high performance and low cost.
Description
The present invention relates to a kind of wear-resistant alloy iron casting of impact fatigue-resistant, belong to iron alloy manufacture method class.
In the development of the national economy, wear resistant alloy is the main material of using of wear-resisting equipment making in metallurgical mine, cement building material, electric power coal, chemical industry traffic and the grain and oil processing; Especially the consumption of abrading-ball, liner plate more has a large capacity and a wide range.For many years, people attempt to seek a kind of ideal wear-resistant material, wish that it has intensity, hardness height, and toughness, impulse fatigue resistance can be good, both wear-resisting, not broken, distortion is little, the low and wear-resistant type material that can be adapted to produce in enormous quantities again of cost.
Present such material such as the rich chromium cast iron that uses, because its production cost height, economic benefit is not obvious in the ore deposit goes out to use, and concerning industries such as cement mill, power station, phosphate fertilizer plant, uses rich chromium cast iron product one-time investment too high, generally producer does not afford to do.
The wear-resistant alloy iron casting that the purpose of this invention is to provide a kind of impact fatigue-resistant wishes that it has intensity, hardness height, the advantage that the impulse fatigue resistance energy is good, wear-resisting, not broken, distortion is little, cost is low.
The wear-resistant alloy iron casting of this impact fatigue-resistant, the percentage composition of its Chemical Composition is:
C 1.70～3.60 Mn 0.20～2.20

P ≤0.12
All the other are Fe and unavoidable impurities.
This impact fatigue-resistant wear-resistant alloy iron casting is to smelt the chrome alum titanium slag pig iron that, the nickel slag pig iron or tungsten slag iron alloy by the dump slag that contains Cr-V-Ti, nickel molybdenum cobalt, tungsten manganese tantalum niobium to add master alloys such as an amount of steel scrap and a spot of silicon, manganese, handle through rotten highly malleablized, the fast cold or Quench moulding of metal mold, special highly malleablized thermal treatment forms.
This impact fatigue-resistant wear-resistant alloy iron casting, its optimum chemical composition degree is:
C 1.70～3.55 Mn 0.20～2.20
Si 0.30～1.80 Cr 0.20～3.80
V 0.05～0.50 Ti 0.02～0.25
W 0～1.00 Mo 0～0.40
Cu 0～0.80 Ni 0～0.60

B 0～0.08 Re 0.02～0.20
Al 0～0.12 S ≤0.07
P ≤0.10
All the other are Fe and unavoidable impurities.
The wear-resistant alloy iron casting of the impact fatigue-resistant of making according to above scheme, its performance is an example to make S φ 80 abrading-balls, and ball falling impact fatigue characteristic number of times is greater than 15000 times, hardness HRC 52～63, and wear resistance is respectively 3～12 times with common forged steel ball wear resistance in mine, thermoelectricity, cement mill; Percentage of damage is all less than 1%.Make liner plate, tup with it, hardness HRC 46～56, and wear resistance is more than 2.5 times of high mangaenese steel; Performance and rich chromium cast iron are suitable, and its manufacturing cost is lower 1000～2000 yuan/ton than rich chromium cast iron like product.
This alloy is applicable to can be widely used in industries such as metallurgical mine, cement building material, electric power coal, chemical industry by serial wear resistance castingses such as making abrading-ball, capsule ball, frotton, tup, liner plate, is a kind of senior wear-resistant anticorrosive novel material.
Further describe the present invention below in conjunction with embodiment.
Impact fatigue-resistant wear-resistant alloy iron casting of the present invention is to smelt the chrome alum titanium slag pig iron, the nickel slag pig iron or the tungsten slag iron alloy that by the dump slag that contains Cr-V-Ti, nickel molybdenum cobalt, tungsten manganese tantalum niobium to add an amount of steel scrap and master alloys such as a small amount of Si, Mn, handle through rotten highly malleablized, the fast cold or Quench moulding of metal mold, special highly malleablized thermal treatment and making.
Its used chrome alum titanium slag pig iron of the wear-resistant alloy iron casting of this impact fatigue-resistant, its main chemical is:
C 3.3～3.8, and Si 0.6～1.4, and Mn 0.8～1.4, and Cr 1.4～2.1, and V 0.3～0.8, and Ti 0.1～0.5, S≤0.12, and P≤0.12, surplus is Fe.The Chemical Composition of its used nickel slag pig iron: C 3～4, and Ni 1～10, and Mo 0.5～5, and Co 0.2～1.0, and Si 0.5～1.3, and Mn 0.5～1.5, S≤0.12, and P≤0.15, surplus is an iron.The Chemical Composition of the tungsten slag iron alloy that it is used is: C 3～5, and W 3～20, and Mn 1～15, and Nb+Ta 0.5～1.2, S＜0.08, and P＜0.10 surplus is an iron.
