Description

Netted wear-resistant bluk recombination liner plate

Technical field

The utility model relates to a kind of composite abrasion-proof inner plate, relates in particular to a kind of netted wear-resistant composite wear-resistant lining board.

Background technology

The version of liner plate is divided into homogenous material structure and composite structure.The homogenous material structure is the primary structure form of most abrasion-proof backing block at present, as: high chrome cast iron lining plate, high manganese steel lining plate, abrasion-resistant alloy steel lining plate, macromolecule nylon liner plate etc.The advantage of this structure is that production technology is simple, and the single performance index is excellent, but its combination property is poor, and the performance indications of excellences such as high rigidity and high tenacity can not be taken into account simultaneously; Even reach certain combination property, also can greatly reduce cost performance because of the lifting significantly of cost through some complicated technologies.But under the actual condition of complicacy, wearing and tearing are multiple abrasion mechanism actings in conjunction and producing, and the single performance of homogenous material liner plate is difficult to the acting in conjunction of the various wearing and tearing of opposing, do not reach not only shock resistance, but also anti abrasive composite request.

The composite structure of liner plate mainly contains layer at present and closes composite construction and particle composite structures.It is the levels composite construction that layer closes composite construction; The upper strata is a hard material; Mostly lower floor is toughness material preferably, and the general methods such as fusion casting, hot pressing, welding, spraying or gummed that adopt are compound, like: duplex metal composite lining board, pottery-rubber combined liner plate, spread ceramic composite pipe etc. certainly.Layer composite uses all right under single low stress abrasive wear operating mode or erosive wear operating mode, but at complex working condition particularly under the impact wear operating mode, then because of upper strata hard material fragility is big, the inefficacy easily of shock resistance difference.The particle composite structures liner plate is prone to come off because the contact area of particle and matrix is little, and shock resistance is very poor, only limits under the very little erosive wear operating mode of impact, use.

Summary of the invention

The purpose of the utility model be to overcome above-mentioned shortcoming and provide a kind of have concurrently excellent impact resistance can and the netted wear-resistant composite wear-resistant lining board of anti-wear performance.

The purpose of the utility model and solve its technical problem underlying and adopt following technical scheme to realize: the netted wear-resistant composite wear-resistant lining board of the utility model; Comprise wear-resistant body and liner plate matrix; Wear-resistant body is embedded in the liner plate matrix, wherein: wear-resistant body is a network structure.

Above-mentioned netted wear-resistant composite wear-resistant lining board, wherein: wear-resistant body is network structures such as regular hexagon grid, positive square grid, circle hole shape grid, triangular mesh or parallelogram mesh.

Above-mentioned netted wear-resistant composite wear-resistant lining board, wherein: wear-resistant body adopts high hardness material,

Above-mentioned netted wear-resistant composite wear-resistant lining board, wherein: liner plate matrix adopting high strength and high tenacity material,

The utility model can know to have tangible beneficial effect from technical scheme, can know from above technical scheme: the wear-resistant body of latticed high rigidity, be embedded in the liner plate matrix of high strength and high tenacity, form netted wear-resistant bluk recombination liner plate.The netted wear-resistant body of high rigidity mainly plays the effect of antagonist grinding abrasion, and intensity is high, the liner plate matrix of good toughness then plays the effect that absorbs impact energy and the wear-resistant monomer of fixing.Be under master's the operating mode with low stress abrasive wear or erosive wear, because wear-resistant body is network structure, the wear-resistant body of high rigidity not only plays the main effect of antagonist grinding abrasion, and can also protect the liner plate matrix that wears no resistance; And be under the main operating mode with the impact wear impacting big, intensity is high, the liner plate matrix of good toughness plays the effect that absorbs impact energy, and is protecting the wearing and tearing of the wear-resistant body opposing material that fragility is big, hardness is high.Because of wear-resistant body is network structure, can be embedded in liner plate inside very securely, convenient simultaneously production.Therefore the utility model can adapt to various complex working conditions, has excellent shock resistance and excellent abrasive ability simultaneously concurrently.The liner plate matrix can adopt the metal material of carbon steel, steel alloy, cast iron, aluminium alloy, copper alloy equal strength height, excellent shock resistance, also can adopt the macromolecule engineering material of good toughness such as nylon, polyurethane, polyethylene.Wear-resistant body then adopts hardness height, the excellent hard materials of anti-wear performance such as Al2O3 pottery, silicon carbide ceramics, zirconia ceramics, WC.Adopt casting method to be cast into one to liner plate matrix and wear-resistant body two parts; Because excellent combination property, can be widely used on the equipment of industry serious wear such as metallurgy, mine, coloured, coal, electric power, building materials, chemical industry, harbour.Concrete applicable product has: the liner plate of hopper, hopper, feed bin, ball mill, Vertical Mill grinding roller, mill, and the feeding pipe of conveying system and elbow etc.

The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
