Description
Technical field
The present invention relates to a kind of ball mill, relate in particular to ball mill and use abrasion-proof backing block, belong to technical field of metal wear in sector applications such as power plant, metallurgy, mine, building materials.
Background technology
Industries such as metallurgical mine, cement building material, electric power, chemical fertilizer, coal, the chemical industry ball mill grinding material that is widely used, wherein liner plate is the main expendable part in the ball mill, its quality had both influenced the grinding machine production operational availability, also ectocrine abrasive lapping cost.30 years of development have been passed through in the production and the application of lining material both at home and abroad, have successively experienced the developmental stage from high mangaenese steel, ordinary white cast iron, ni-hard cast iron, high-chromium white cast iron to the middle-low alloy steel of modified high manganese steel and various Q-tempering technologies.In the domestic practical application, still be that high mangaenese steel rules all the land, do not replaced that this mainly is to be determined by the problem that exists on quality own, stability and the technologies such as middle-low alloy steel by high alloy iron, middle dilute-alloy martensite steel.In several kinds of present main flow materials, the one, its toughness of Hadfield Steel is high, and original hardness is low; The work hardening of main dependence austenite improves its hardness in the use, and after abundant work hardening, its hardness is brought up to HB400-500 by original HB200; Use obtains good result of use under the high impact loads condition; But under medium and small shock load condition, use, fully work hardening of austenite, it wears no resistance; The 2nd, middle-low alloy steel discloses a kind of low-alloyed ball mill wearing liner plate and ME like Chinese invention patent CN1080327, and the content of each material composition (weight %) is: C0.35-0.5%; Cr0.8-1.5%, Si0.6-1.2%, Mo0.3-0.5%; Mn0.6-1.4%; Cu0.5-1%, 1#Re0.01-0.1%, surplus is Fe.The principal feature of this invention is to adopt the rotten processing of 1#Re simultaneously and improve Cu content, has improved the modification effect of 1#Re, the effect that played crystal grain thinning, purifies crystal boundary, improves hardening capacity and tissue and performance uniformity; Owing to contain expensive molybdenum and copper, therefore, production cost is higher; In addition, only add rare earth, purification and thinning effect are not so good; Therefore it is lower to invent lining material toughness, and impelling strength is greater than 18J/cm
2The 3rd, rich chromium cast iron, the wear resistance of this material is good, but poor toughness.Therefore the comprehensive Corrosive Impact Wear performance of these materials and bad.
Summary of the invention
The object of the invention is to provide a kind of High Chrome Alloy Steel abrasion-proof backing block; This liner plate not only has good Corrosive Impact Wear performance; And cost is lower, solves liner plates such as existing high mangaenese steel and middle-low alloy steel and hits the problem that corrosion wear characteristic is relatively poor, work-ing life is lower with steel drift.
The technical scheme that realizes the object of the invention is:
A kind of High Chrome Alloy Steel abrasion-proof backing block; It is characterized in that said liner plate alloying constituent by weight percentage is: C:2.20-2.50%, Cr:15-18%, Ni:0.3-0.5%, Mn:1.0-1.2%, Mo:0.3-0.5%, Cu:0.4-0.65%, Ti:0.15-0.25%, Si are not more than 0.6%, P and S all are not more than 0.035%, Re:1.8-2.2%, and surplus is Fe and unavoidable impurities.
Design considerations of the present invention is:
C:C is one of constituent element in the steel.The control of C amount is intensity, hardness, toughness, corrosion proof cooperation in order to guarantee that alloy obtains on the one hand in the liner plate of the present invention.Carbon content is on the low side, and the toughness of material will be improved, but wear resistance can be not enough; Carbon content is too high, and the hardness of material, wear resistance can be improved, but toughness can descend, and therefore C content of the present invention is controlled between the 2.2-2.5%.
Cr: chromium is the hardening capacity that improves steel, the important element that steel is strengthened, and also is simultaneously the corrosion proof important element that improves steel.In the abrasion-proof backing block material in the past, except that the rich chromium cast iron chrome content was higher, chrome content was lower than 5% more in the general material.It is between the 15-18% that liner plate of the present invention is selected chromium content.Because chrome content on the low side is unfavorable to the erosion resistance of material; And higher chromium content is unfavorable to toughness.The selection of chrome content also will take into account the rational Match of chromium amount and carbon amount in addition.
Si: element silicon can improve the castability of foundry goods, and helps the deoxidation of molten steel degasification.The casting high quality steel is high silicone content suitably, can in use improve the resistance of oxidation of material.But the too high fragility that can increase material of silicon content.Evidence, Si and Ti add than the Ti of independent adding same amount or Si simultaneously can obtain better wear resistance, thereby its content is controlled at and is not more than 0.6%;
Mn: manganese mainly plays deoxidation outgassing and the hardening capacity that improves cast iron, but too high levels can produce the abundant residues austenite, and is unfavorable to material wear ability, should be controlled at 1.0-1.2%;
Ni: add solidity to corrosion, toughness and hardening capacity that nickel element can improve steel, under multi-element alloyed condition, element actings in conjunction such as nickel and Cr, Mo, obvious to corrosion proof raising effect.And wet-type ball mill liner plate working condition requires lining material that sufficiently high solidity to corrosion, toughness, hardening capacity should be arranged.But owing to costing an arm and a leg of Ni, in order to control cost of alloy, add-on is controlled at 0.3-0.5%.
Mo: add a small amount of Mo element and can improve alloy hardening capacity.Simultaneously, Mo helps eliminating the anti intercrystalline corrosion ability of temper brittleness and raising alloy.In order to control cost of alloy, add-on is controlled at 0.3-0.5%.
Cu:Cu can improve toughness and thermal conductivity, but excessive easy generation copper-rich phase and tiny crack, therefore, the content of Cu is controlled at 0.4-0.65%.
Ti: titanium on the one hand plays desulfurization, degass in steel-making, the cleaning molten steel effect; Carbide that the more important thing is Ti then Mass further stops the austenite creep of material under the high temperature in austenitic matrix, and carbide is at high temperature migrated gathering gradually.Just because of this distribution of carbides very cleverly and effect, the strength of alloy is increased, and improved Creep Plastic, and strengthen the carburizing drag.Take all factors into consideration Ti content is controlled at 0.15-0.25%.
Re:Re helps improving the plasticity of cast iron, makes it both keep high firmness, HS and characteristic such as high temperature resistant, can improve the toughness of cast iron again, but its price is higher, takes all factors into consideration Re content is controlled at 1.8-2.2%.Adding Re in the cast iron is one of principal feature of the present invention.
P, S:S and P are harmful element, and P can cause hot-short, and S is prone to cause cold short.For intensity, toughness and the wear resistance that guarantees cast iron, must the strict content of controlling S, P.
The present invention compared with prior art has following advantage:
1. liner plate of the present invention compared with prior art, has excellent thermotolerance and solidity to corrosion through alloy designs, and its hardness is HRC60-63, and impelling strength reaches 7.5-8.5MJ/cm
2, tensile strength reaches 875-910N/cm
2, higher hardness and wear resistance are arranged, also have higher intensity and toughness preferably simultaneously, its wear resistance improves more than 2 times than the high manganese steel lining plate life-span.
2. main alloy element content such as Ni, Mo, Mn are not high in the liner plate of the present invention.Compare with the low carbon high alloy steel liner plate, because ni content is low, the liner plate cost obviously reduces, and its cost performance is higher.
