Abstract
The utility model provides an anti-wear ball mill liner plate comprising a liner plate base body; a composite layer is coated on the working surface of the liner plate base body; the composite layer is composed of substrate metal and a plurality of hard ceramic particle blocks, wherein the hard ceramic particle blocks are staggered like a regular mesh in the substrate metal. The hard ceramic particle blocks are arrayed like the regular mesh, the hard ceramic particle blocks and the molten substrate metal are subjected to metallurgical chemical reaction under the high-temperature action of molten substrate metal; meanwhile, due to the heat absorbing action of the hard ceramic particle blocks, the partial temperature is reduced, the crystallizing process is shortened, the further diffusion of elements in the hard ceramic particle blocks is blocked, and thus the excellent metallurgical transition combination is formed between the substrate metal and the hard ceramic particle blocks, interfaces are combined fixedly, the wearing resistance and the toughness are combined organically, the entire property of the obtained ball mill liner plate is enhanced significantly, and the ball mill liner plate is widely used in anti-wear fields such as mines, electricity, metallurgy, coals, building materials, and the like.
Description
Technical field
The utility model relates to a kind of ball grinding machine lining board, particularly a kind of wear-resistant ball grinding machine lining board.
Background technology
Industrial trade extensive use ball mills such as coal, metallurgy, mine, electric power, building materials, refractory material, the energy carry out the fragmentation of material, and ball grinding machine lining board is most important wearing and tearing attrition component.The used ball grinding machine lining board material of every profession and trade mainly contains several kinds of single metal material such as potassium steel, multi-element low alloy steel, Cr series white cast iron at present.There is not hard carbide in the potassium steel; Thereby hardness is low, only under high load capacity, high impact stresses, realizes that austenite is to martensitic solid-state phase changes and work hardening; Just can give full play to its wearability; And under general operating mode, so that potassium steel produces drawing hardening effect, so wearability does not reach ideal value to material to the impact strength deficiency of ball grinding machine lining board; Also do not have hard carbide in the multi-element low alloy steel, can not resist being pressed into and paddling of abrasive material, in use the surface produces a large amount of cutting and flow low-cycle fatigue, so wearability is bad; Though the chromium series cast iron anti-wear performance is good, its plasticity and toughness difference ruptures easily, and because monoblock cast will consume a large amount of yttriums.
The ball grinding machine lining board of single metal material preparation is owing to can not take into account high tenacity, high strength, high rigidity, high-wearing feature; Applying working condition had selectivity; Can not satisfy actual needs; Therefore have only through combination process to combine the material of different qualities, process composite lining plate of ball mill and take into account the each side mechanical mechanics property, could satisfy the needs of various operating modes.CN01131841.4 has invented a kind of composite lining with metal wire screen in nanometer structure and preparation technology thereof, and this is invented with the wild phase of metal wire screen in nanometer structure as the organic matter matrix; CN02280529.X discloses a kind of wear and shock-resistant composite liner, and sticking rubber plate on metal base plate studs with one group of hard layer again on rubber slab; CN91221902.5 discloses a kind of ball mill wearing composite liner, on the medium carbon structural alloy steel matrix, inlays the rich chromium cast iron piece; CN00259470.6 discloses the wear-resisting composite liner of a kind of ceramic superelevation, is employed on the steel plate technology with polyethylene bonding hard ceramic piece; CN200410026039.7 has invented a kind of preparation method of cold rolled high manganese steel strip stack composite liner; CN200610018444.3 has invented aluminium oxide ceramic composite lining board and preparation method; It is that aluminium oxide ceramics powder, acetone, glass microballoon, triethylene dimethylsilane, titanate esters and quartz sand are mixed by a certain percentage, and warming and pressurizing is processed composite liner then; 200810124286.9 disclose a kind of manufacturing new technology of duplex metal composite lining board, be cast to one to two kinds of metal materials and constitute liner plate; CN03239655.4 discloses a kind of carborundum-elastic abrasion-proof material composite liner, hot-cast one deck polyurethane or rubber on silicon carbide substrate; CN200420035134.9 discloses a kind of large-size ball mill ceramic composite lining board, on rubber sheet gasket, clamps the fine ceramics piece; CN200820028103.9 discloses a kind of hard silk screen abrasion-proof composite liner, is compound to the woven wire through nitriding or Carburization Treatment on the parent metal.CN201010207685.9 discloses a kind of composite lining plate of ball mill and preparation method thereof; Be compound to hard ceramic particles on the liner plate working face; But the bad control of its macroscopic interface; Composite bed comes off under impact and wear working condition easily, and its preparation technology is easy to generate defectives such as pore, slag inclusion.More than various liner plates and preparation technology thereof have can't satisfy actual use needs at all, the complicated process of preparation that has, production cost is high, can't be through the production of row large-scale industrialization.
The utility model content
The purpose of the utility model is to provide a kind of can satisfy the high performance ball grinding machine lining board that uses under the complex working conditions such as various wearing and tearing, impact.
The utility model provides a kind of so wear-resistant ball grinding machine lining board, comprises the liner plate matrix, and the working face of said liner plate matrix is attached with composite bed on (zone that withstands shocks and wear and tear), and this composite bed is made up of the ceramic on metal particulate reinforced composite.
Said ceramic on metal particulate reinforced composite is made up of substrate metal and hard ceramic particles piece, and wherein the hard ceramic particles piece is staggered into netted being distributed in the substrate metal of rule.
The thickness of said composite bed accounts for 1/20～1/10 of liner plate matrix thickness.
The hard ceramic particles piece becomes regular net distribution in the liner plate working region in this liner plate that has a composite bed, improves its shock-resistant and anti-wear performance.Hard ceramic particles is a kind of in aluminium oxide, carborundum, tungsten carbide, silicon nitride, the titanium nitride or any several kinds, the hard ceramic particles piece that is formed by sintering or bonding; Substrate metal is potassium steel, steel alloy, high chrome, ordinary carbon steel, casting pig or spheroidal graphite cast-iron.
Compare with prior art, the utility model has following beneficial effect:
The utility model is arranged into the hard ceramic particles piece regular netted, and under the high temperature action of substrate metal liquid, metallurgical combination reaction takes place for hard ceramic particles and substrate metal liquid; Because the heat-absorbing action of hard ceramic particles has reduced local temperature, shortened crystallization process simultaneously; Having hindered the element in the hard ceramic particles further spreads; Combine thereby make hard ceramic particles piece and substrate metal form the excellent metallurgical transition, the interface combines firmly, wearability and toughness organic unity; Gained ball grinding machine lining board overall performance significantly improves, and can be widely used in wear-resisting fields such as mine, electric power, metallurgy, coal, building materials.
