Description
Technical field
The invention belongs to preparation equipment technical field, alloy ultra-high strength and toughness liner plate and system during especially a kind of disintegrating machine is used
Preparation Method.
Background technology
The liner plate of gyratory crusher, it is general to use potassium steel and modified high manganese steel, carbon alloy steel and chromium cast iron contained, strong
Impact load under, form hardening and wear-resisting toughness on its surface.But in the thin broken stage because shock loading is smaller,
Under weak impact loading, potassium steel is not wear-resisting.
The use industrial and mineral inclement condition of mine lining plate of cone crusher, had not only been hit but also frayed.Justify in recent years both at home and abroad
It is now undesirable with various material liner plate using effects in conic crusher, it is mainly shown as that the life-span is shorter.Conventional liner material quality is high
Manganese steel and ultra-high manganese steel toughness are had a surplus, and hardness, wear-resisting, corrosion resistance is not enough；Low-alloy steel toughness and corrosion resistance are inadequate；Gao Ge
Cast iron wearability is good, but toughness is not enough；So that the service life of liner plate is very short.Current grade of ore reduction, its hardness increase is needed
Want liner plate to have enough hardness and toughness, just can guarantee that the life-span；It is generally acknowledged that the hardness of preferable material need to reach HRC50, it is tough
Property also reaches 50J/cm-2More than.
The content of the invention
Alloy ultra-high strength and toughness liner plate and preparation method in being used it is an object of the invention to provide a kind of disintegrating machine, by closing
The composition design and Design of Heat Treatment Process of reason provide a kind of with low cost, excellent performance, the simple lining board of crusher of technique.
Disintegrating machine of the present invention percentage by weight of alloy ultra-high strength and toughness liner plate chemical composition in is：C 0.25%~
0.45%, Si 1.0% ~ 1.5%, Cr 0.5% ~ 1.6%, Mn 1.8% ~ 2.2%, Mo 0.3% ~ 0.5%, B 0.002% ~ 0.004%, Nb
0.03% ~ 0.05%, Ti 0.01% ~ 0.03%, RE≤0.4%, surplus is iron and inevitable impurity.
Alloy ultra-high strength and toughness liner plate chemical composition act as during disintegrating machine of the present invention is used：
C：Carbon is that bainitic steel obtains good obdurability matching and the most important element of comprehensive mechanical property.Carbon in steel with
The carbide of other alloying elements formation, which is solid-solution in ferrite, strengthens matrix, the intensity and hardness of steel is all increased substantially,
So as to improve the wearability of steel.Carbon content is too high, and hardness, the wearability of material can be improved accordingly, but is easily formed during heat treatment
Crackle, material fragility is big；Carbon content is too low, and hardness is low, wearability is not good after casting quenching.
Si：Silicon is solution strengthening element, can prevent Austenite Grain Growth, moves to right bainite transformation C curve, makes bayesian
Body transformation occurs in lower temperature.Silicon has good deoxidizing capacity, improves intensity, wearability and the yield strength of steel.Together
When silicon can hinder in drawing process the formation of carbide nucleus and grow up, suppress temper brittleness, carbon do not separated out in ferrite forward position
Compound, adds the stability of retained austenite, improves the temper resistance of martensite.But block iron element excessively occurs in silicon
Body, reduces toughness, and the silicon of moderate content is for ensureing that toughness is most suitable.
Cr：Chromium can improve the quenching degree and temper resistance of steel in steel, make F-P transition curves and bainite transformation curve
Separation.Chromium can be solid-solution in ferrite, can form a variety of carbide with the carbon in steel again, improved the antioxygenic property of steel, carried
Gao Gang wearability.When chromium content is less than 2%, the plasticity of steel can be improved, too high chromium can increase temper brittleness.
Mn：Manganese largely dissolves in ferrite, strengthens matrix, improves intensity, quenching degree and wearability, moreover it is possible to slow down pearlite
The forming core of alloyed cementite can effectively improve the stability of austenite with growing up during transformation, so as to improve the toughness of material.Necessarily
The manganese of content coordinates with boron, can protrude bainite transformation area, bainite is obtained in the range of larger cooling rate.While the price phase of manganese
To cheap, molybdenum amount can be reduced by improving manganese content.
Mo：Molybdenum can significantly improve the quenching degree of material, solution strengthening matrix, crystal grain thinning, energy when being used in mixed way with Cr, Mn
Reduce temper brittleness, the toughness and anti-fatigue ability of reinforcing material.After conditioned or normalizing and tempering heat treatment, it can obtain excellent
Good mechanical property.But in order to control alloy to add excessively, typically 1% or so.
B：Minimal amount of boron is postponed and Bainite Region is become flat significantly with regard to Neng Shi high temperature transformations area.Into bainitic steel
Quenching degree can be significantly improved and improve toughness by adding micro B element, and B and Mo compound actions make overcooling austenite to ferritic etc.
Warm transition curve is further moved to right, and bainite transformation initial is substantially protruded.But, B is that a chemical property is more active
Element, easily form boride segregation in crystal boundary, reduce the toughness of steel.When B content is more than 0.006%, easily separate out thick
Fe23 (CB) 6, will cause boron crisp.
Nb、Ti：Niobium can improve bainite matrix strength, be mutually promoted between boron so that the compound ratio that adds is individually added into
Niobium or boron can more be played a role, the addition of trace niobium, and the carbonitride Nb of the indissoluble of a large amount of Dispersed precipitates is produced in the base
(CN), the pinning dislocation in drawing process so that dislocation is not easy to recover and disappeared, it is ensured that the intensity of matrix；Nb and B etc. is combined
Add, reduce the transition temperature of bainite, further thinning microstructure improves matrix middle position dislocation density；Titanium is that strong carbide is formed
Element, grain refinement effect clearly, can eliminate the primary crystallization and crystal boundary element segregation that is typically heat-treated and can not eliminate,
Steel belt roof bolt fragility is reduced, quenching degree can be also improved, instead of part noble element.But too high niobium, titanium can cause thick be mingled with
Thing is formed.
RE：RE can improve as cast condition crystalline structure, crystal grain thinning, increase the consistency of steel, improve field trash property, form and
Distribution, reduction objectionable impurities elements are improved the toughness of steel, the corrosion resistance to steel also has necessarily in the degree of segregation of crystal boundary
Influence.The Adding Way and addition of rare earth have a great impact to Steel Properties, and adding excessively may deteriorate the performance of steel.Become
The matter agent rare earth alterative that 10min will be preheated before tapping（≤ 0.4% molten steel weight）Add the addition of ladle bottom rare earth
The general ratio and rare earth yield according to [RE]/[S] of amount determines that the rate of recovery is between 10%~30%.By empirical equation [RE]/
[S]=2.0 ~ 2.5, calculate rare earth adding quantity=0.4%.
The preparation method of alloy ultra-high strength and toughness liner plate during disintegrating machine of the present invention is used.
Pure iron is melted in vaccum sensitive stove, in 1500 ~ 1550 DEG C of tappings, alloy is added into vaccum sensitive stove before tapping
Alloying is carried out, while carrying out desulfurization, deoxidation, detecting and adjust chemical element component content, taps preceding ten minutes and adds Y base weights
Rare earth alterative carries out Metamorphism treatment；When temperature drops to 1450 ~ 1470 DEG C in vaccum sensitive stove, sand mold mould type is poured into
In chamber；Casting terminates rear natural cooling 1.5h ~ 2h, is unpacked after cooling and casting is cleared up.With 80 ~ 100 DEG C/h speed
