Description
Technical field
The present invention relates to a kind of wire drawing production unit material, be specifically related to a kind of wear resistant alloy material that can prepare long service life, high temperature resistant, wear-resisting built-up type wiredrawing step pulley.
Background technology
In water tank drawbench wire drawing work, between steel wire and cone pulley in high-speed friction condition, so cone pulley surface meeting groove, when groove arrives certain depth, after the irregular edge friction of steel wire and groove, surface can produce burr, the oilness variation on cone pulley surface, that serious meeting causes is wired, break; And traditional cone pulley is generally monoblock type, the cost of changing after wearing and tearing is higher.Although the split type wiredrawing step pulley occurring at present, but exist, integral body because of wiredrawing step pulley is important heavierly causes installation and maintenance inconvenient or because of problems such as the problem dismounting of structure are inconvenient; And, according to contriver, study, put into practice and find, the structure of still improving cone pulley not can solve the problem of cone pulley wearing and tearing, and cone pulley is easy to wear is because cone pulley making material selection is improper to a great extent, be in cone pulley component, to lack wear-resisting element, or content very little etc.Therefore,, although people constantly improve cone pulley structure, get less than more preferably effect.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of wear resistant alloy material is provided, and take its built-up type wiredrawing step pulley of preparing as material, fundamentally solve wiredrawing step pulley problem easy to wear, again by further improving in structure, extended its work-ing life greatly, at utmost reduce wiredrawing step pulley wear rate.
To achieve these goals, the present invention has adopted following technical scheme:
A wear resistant alloy, wherein, the component of this wear resistant alloy comprises chromium, molybdenum, manganese, nickel and iron; And the quality of this wear resistant alloy of take is benchmark, and the content of each component is: chromium 35～45%, and molybdenum 1～2%, manganese 1～5%, nickel 5～15%, surplus is iron and impurity.
As the present invention, further illustrate, the content of each component of the above wear resistant alloy is: chromium 39～41%, and molybdenum 1～2%, manganese 2～4%, nickel 10～13%, surplus is iron and impurity.
As the present invention, further illustrate, the content of each component of the above wear resistant alloy is: chromium 40%, and molybdenum 1.5%, manganese 3%, nickel 12%, surplus is iron and impurity.
As the present invention, further illustrate, above-described impurity comprises micro-carbon, phosphorus, sulphur.
A built-up type wiredrawing step pulley that uses above-mentioned wear resistant alloy to prepare, wherein, this wiredrawing step pulley comprises the installation shaft and the cone pulley sheet that uses wear resistant alloy to prepare that is provided with key; Described cone pulley sheet is provided with axle center hole and keyway, and the size of keyway and the key of installation shaft match; The cone pulley sheet of different diameter is assemblied in installation shaft by diameter from left to right from big to small successively; And the wire casing place of cone pulley sheet is coated with wolfram varbide coating.
The thickness of above-mentioned wolfram varbide coating is 1～3cm.
Built-up type wiredrawing step pulley of the present invention adopts conventional production process: (1) carries out just refining by raw material; (2) refining; (3) cooling forming; (4) rolling; (5) quench; (6) tempering; (7) coating, obtains cone pulley finished product.
The performance of some component elements that below the present invention adopted is carried out some introductions:
Chromium (Cr), chromium can improve hardenability and the tempering resistance of wiredrawing step pulley effectively, improve the intensity of wiredrawing step pulley, and chromium can also reduce the activity of carbon, improve the carbon that soaks of wiredrawing step pulley, and form fine carbide, and can reduce steel surface decarburization and greying tendency in heating, rolling and heat treatment process, improve toughness and wearability; But, during chromium too high levels, forming in a large number on the contrary the carbide of chromium, the bullet that worsens wiredrawing step pulley subtracts performance and toughness.Therefore, in the present invention, the content of controlling chromium in wiredrawing step pulley is 35～45%(weight percent), more preferably 39～41%, optimum content is 40%.
Molybdenum (Mo), molybdenum is stainless steel non-corrosive, corrosion resistant key element; Therefore, molybdenum additives has very large impact to the performance of wiredrawing step pulley, and a small amount of molybdenum is added among wiredrawing step pulley, can make wiredrawing step pulley have very excellent performance, can greatly increase the wear resisting property of wiredrawing step pulley, increases the service life.High strength alloy steel can improve steel hardness, intensity and toughness containing molybdenum, and good weldability and the corrosion resistance of tool.When cast iron adds after 0.3%～2.0% molybdenum, will greatly improve tension, bending resistance and fatigue resistance, also can improve the homogeneity of casting structure, this especially seems important to massive casting, these foundry goods are widely used in automobile making, pressure pipeline and mold etc., and in processing industry, molybdenum is used more extensively.Utilize thermal expansivity little, the molybdenum that heat conduction is strong, high strength is good or molybdenum base alloy, significantly extend die life; In iron, steel and other metal, add alloying element just can improve their performance, as hardenability, under intensity, erosion resistance and resistance to abrasive property.But during the too high levels of molybdenum, worsen plasticity, toughness and the processing characteristics of wiredrawing step pulley.Therefore, in the present invention, it is 1～2%(weight percent that contriver has controlled the content of molybdenum in wiredrawing step pulley), optimum optional 1.5%.
Manganese (Mn), manganese is the effective element of deoxidation and desulfurization, as reductor, uses, and can improve hardening capacity and the intensity of wiredrawing step pulley when thermal treatment, can reduce the solid solubility of N and be difficult to function as described above when addition is less than 1%.Therefore, the content that the present invention need to be controlled at manganese in wiredrawing step pulley is 1～5%(weight percent), further preferably can be 2～4%, optimum content is 3%.
Nickel (Ni), nickel has good over-all properties, can resistance to various acid corrosions and stress corrosion, and also property is tough and tensile, is magnetic and good plasticity-, and welding property might as well; Under 650～1000 ℃ of high temperature, having higher intensity and anti-oxidant, resistance to combustion gas corrosion ability, is the class alloy most widely used in superalloy, hot strength is the highest.In the present invention, the content that is controlled at nickel in wiredrawing step pulley is 5%～15%, and optimum content is 12%.
Advantage of the present invention:
High temperature resistant, wear resisting property is high, long service life.First, the technical scheme that the present invention proposes is fundamentally solving wiredrawing step pulley problem easy to wear, in preparing the material of wiredrawing step pulley, increase molybdenum ore, nickel minerals, make the molybdenum element, the nickel element that in wiredrawing step pulley finished product, contain rational proportion, greatly increase the wear resisting property of wiredrawing step pulley, extend the work-ing life of wiredrawing step pulley.Secondly, at the wire casing place of cone pulley sheet, be coated with wolfram varbide coating, structurally further improve, again promote the wear resisting property of wiredrawing step pulley, extend the work-ing life of wiredrawing step pulley.According to test, more than wiredrawing step pulley of the present invention can be used half a year in normal production.
