Description
Technical field
The present invention relates to cement manufacture field, particularly relate to a kind of cement ball mill abrasion-proof backing block and manufacture method thereof.
Background technology
Ball mill is the milling equipment that the industries such as metallurgical ore grinding, cement, generating are conventional.The Main Function of ball grinding machine lining board is protection grinding machine and drives abrading-ball be ground material and pulverize.The main failure forms of ball grinding machine lining board is the abrasive wear under small capacity hump, and according to statistics, the iron and steel that China consumes every year on ball mill reaches millions of tons.The most how to improve the focus of the wearability always research of ball grinding machine lining board.
Now commonly using lining material is high strength steel, but its wearability is the most poor, and service life is short, and due to the poor toughness that high strength steel is general, liner plate the most easily ftractures, it is broken to collapse so that repair demolition is extremely difficult；And with low-carbon alloy steel making ball grinding machine lining board, there is again intensity and hardness is low, the deficiency that wears no resistance；In order to improve obdurability and the wearability of steel alloy, generally will add the alloying elements such as molybdenum, nickel, chromium, tungsten, vanadium, the most in short supply along with alloy resource, molybdenum, nickel, chromium, tungsten, vanadium etc. are becoming tight alloy supply day, price rapidly goes up, and causes common iron and steel high-abrasive material production cost constantly to rise；Meanwhile, current main flow liner plate mostly is martensite steel sections, easily undergoes phase transition more than 250 DEG C, causes liner plate hydraulic performance decline, is therefore not suitable for working under the operating mode of long-time, high intensity.It addition, many of existing liner plate considers the intensity of liner plate itself, toughness and corrosion resistance etc., do not account for the ability of liner plate secondary process material, and material easily sticks on liner plate；Meanwhile, stainless steel cost is high and the most wear-resisting, and high strength steel is wear-resisting but the most corrosion-resistant, all easily due to abrasion or corrosion impact working face, reduces the degree of purity of made material simultaneously.
In the Patents the most applied for, patent " a kind of large-size ball mill liner plate and casting method thereof " (application number: 201010294909.4, publication date: 2011-01-26), disclose a kind of anti-wear performance excellent, hardness is high, good toughness, the preparation method of intensity height liner plate, in conventional steel liner plate, add the multiple alloying elements such as silicon, chromium, molybdenum, boron, niobium promote wearability and the toughness of liner plate, but this liner plate is the most corrosion-resistant；It addition, remain martensite steel sections, non-refractory；Simultaneously as matrix limits, its impact resistance is the most poor, and work long hours cracky.Patent " lining sheet for ball mill of a kind of high-wear resistance " (application number: 201410364512.6, publication date: 2014-10-29), disclose a kind of essence high-strength stainless steel liner plate as base material, and the average tempering technique used, high temperature resistant, but it have employed the alloying element such as chromium, titanium in a large number, raw material are smelted difficult and expensive, simultaneously result in this liner plate Castability poor, cannot be used for manufacturing large-scale liner plate, range of application is not wide, meanwhile, the addition of a large amount of carbon also make this liner plate cannot complete austenitizing, corrosion resistance is the best.It addition, above-mentioned two parts of patents the most only consider the intensity of liner plate itself, toughness and corrosion resistance etc., do not account for the ability of liner plate secondary process material, and material easily sticks on liner plate.
Summary of the invention
For drawbacks described above present in prior art, it is desirable to provide a kind of wear-resisting, high temperature resistant, corrosion-resistant, impact resistance, good economy performance, length in service life, material are difficult to adhere to, can secondary process material and the cement ball mill abrasion-proof backing block of made material high purity.
To achieve these goals, the present invention by the following technical solutions: a kind of cement ball mill abrasion-proof backing block, including the base material possessing installed surface and working face, it is characterised in that: described base material working face undulate or concavo-convex latticed；Described base material face surface is also coated with wear-resistant coating, and this wear-resistant coating is the tungsten carbide system wear-resistant coating using HVAF coating.
Above-mentioned cement ball mill abrasion-proof backing block, wherein: described tungsten carbide system wear-resistant coating is preferably WC-CoCr or WC-Co, and tungsten carbide powder particle grades contained by it is WC10-WC100.
Above-mentioned cement ball mill abrasion-proof backing block, wherein: the composition of tungsten carbide system wear-resistant coating also includes the one in tantalum carbide powder, titanium carbide powder or combinations thereof thing；A kind of or combinations thereof thing in described tantalum carbide powder, titanium carbide powder accounts for the 3-5% of tungsten carbide system wear-resistant coating gross mass the most altogether.
Above-mentioned cement ball mill abrasion-proof backing block, wherein: described base material uses mild steel manufacture, described mild steel includes that carbon content is less than carbon steel and the carbon content steel alloy less than 0.25% of 0.25%.
The manufacture method of the cement ball mill abrasion-proof backing block of above-mentioned water, it comprises the following steps:
(1) select the carbon content carbon steel less than 0.25% and the carbon content steel alloy less than 0.25% as mild steel base material；
(2) mild steel base material is processed as the size needed；
(3) base material working face is processed as the shape needed, such as waveform or concavo-convex latticed or stepped；
(4) raw material of configuration tungsten carbide system wear-resistant coating: select tungsten carbide powder WC-CoCr or WC-Co, it is ensured that its particle grades is WC10-WC100；
(5) using HVAF technique, fire flame speed >=2100m/s, material powder step (3) configured sends into combustion flame, produces fusing or the particle of semi-molten, and high-speed impact, on base material face surface, forms wear-resistant coating.
The manufacture method of above-mentioned cement ball mill abrasion-proof backing block, in its step (3) in addition to selecting tungsten carbide powder, the 3-5% also pressing tungsten carbide system wear-resistant coating gross mass mixes the one in tantalum carbide powder, titanium carbide powder or combinations thereof thing, mixes.
Compared with the prior art, due to the fact that and have employed such scheme, prepared liner plate working face wearability is high, and case hardness is at more than 2200HV, far above the hardness of conventional High Intensity steel about 700HV；Mild steel strong shock resistance, and low cost, although itself not wear-and corrosion-resistant, but owing to working face is coated with wear-resisting, anti-corrosion tungsten carbide coating, solve its working face wear-and corrosion-resistant problem, installed surface is fitted with shell, the most perishable, even if there being slight erosion to nor affect on its service behaviour and the degree of purity of made material；Tungsten carbide material high abrasion resistance, have concurrently shock resistance, good toughness mild steel as base material, working loss is low, and adaptability is good, and service life is long, good economy performance；Base material working face is wavy or textured, and the coating being coated in its surface also thus presents same form, can assisted machining material, preferred coating composition further increases the antiknock ability of coating, is beneficial to cut cement granules；Meanwhile, tungsten carbide coating uses HVAF to be coated in the surface of low-carbon steel that affinity is good, and adhesion is good, difficult drop-off, furthermore tungsten carbide cutting power is strong, wearability good, and the operating efficiency of ball mill can be greatly improved, and makes prepared material high purity simultaneously.
