Abstract
The utility model relates to wear resistance castings field, provides a kind of wear-resistant casting ledge of castingin ceramic wear-resisting block, comprise casting ledge body and castingin in the ceramic wear-resisting block of ledge body local location.Described casting ledge body material is low-alloy steel, ceramic wear-resisting block main species has aluminium oxide ceramics, zirconia ceramics, silicon carbide ceramics and composite material thereof, and the concrete size of wear-resistant block, quantity, spread pattern can design within the specific limits according to ledge foundry goods castingin position.The casting ledge of the castingin ceramic wear-resisting block that the utility model provides, its manufacturing process is simple, insert difficult drop-off, under the prerequisite ensureing the original intensity of casting ledge, toughness properties index, achieve the significantly lifting of wear resisting property, extend the service life of complete machine, remarkable in economical benefits.
Description
Technical field
The utility model relates to wear resistance castings field, particularly a kind of wear-resistant casting ledge of castingin ceramic wear-resisting block, for the wear-resistant ledge foundry goods of coal mine scraper conveyor.
Background technology
Coal mine machinery running environment is severe, most of equipment works under the working conditions such as high speed, heavy duty, vibration, impact, friction, corrosion, the inefficacy of coal mine machinery is mainly with wearing and tearing and be fractured into master, and the economic loss that national colliery system causes because of wearing and tearing is every year in tens billion of unit.Slat conveyer uses the widest load transfer device in coal mining enterprise, and wear out failure is its main failure forms.Casting ledge is the main component part of slat conveyer main component intermediate channel, also be one of parts the most serious causing destruction because of wearing and tearing, the most serious position of wearing and tearing occurs in the parts such as ledge " M " groove notch, is product early failure major cause.At present in raising casting ledge resistance to abrasion, manufacturing enterprise attempts, applies multiple means and method, as improved material wear ability by adding alloying element, but limit by factors such as welding usability, toughness of products requirement, Alloys Casting performance and prices, resistance to abrasion improves limited; At notch local surfacing wear-resistant alloy layer, its resistance to abrasion significantly improves, but need be equipped with corresponding production facilities and professional operator, technique relative complex, and operation is long, and productive costs is higher; The method of other such as spraying abrasion-proof alloy-layer, fundamentally can not solve the problem that casting ledge is not wear-resisting.
Summary of the invention
The wear-resistant casting ledge that the utility model provides, adopts the process of foundry goods local castingin ceramic wear-resisting block, under the prerequisite ensureing the original intensity of casting ledge, toughness properties index, achieves the significantly lifting of wear resisting property.
The technical method that the utility model technical solution problem adopts: a kind of wear-resistant casting ledge of castingin ceramic wear-resisting block, comprise casting ledge body and castingin in the ceramic wear-resisting block of ledge body local location.Described casting ledge body material is low-alloy steel, and ceramic wear-resisting block main species has aluminium oxide ceramics, zirconia ceramics, silicon carbide ceramics and composite material thereof.Ceramic wear-resisting block cross sectional shape is designed to peripheral band gradient or boss, or centre with through hole with slip-off preventing, concrete size, quantity, spread pattern are determined according to ledge foundry goods castingin position; Wear-resistant block small end face is concordant with ledge cast(ing) surface.
The utility model has the advantages that: ceramic wear-resisting block adopts imbedding process to embed casting ledge body, difficult drop-off, under the prerequisite ensureing the original intensity of casting ledge, toughness properties index, achieves the significantly lifting of wear resisting property, extend the service life of complete machine, remarkable in economical benefits.The wear-resistant casting ledge manufacturing process of this castingin ceramic wear-resisting block is simple, easy and simple to handle, with short production cycle, without the need to increasing equipment, without the need to other energy resource consumption.
Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is casting ledge " M " notch local castingin ceramic wear-resisting block front view;
Fig. 2 is casting ledge " M " notch local castingin ceramic wear-resisting block left view;
Fig. 3 is ceramic wear-resisting block structure schematic diagram.
In figure: 1, cast ledge body, 2, ceramic wear-resisting block.
Detailed description of the invention
If Fig. 1 is a kind of embodiment of the present utility model, at casting ledge wear out failure the most serious position " M " groove notch position castingin ceramic wear-resisting block, specifically comprise casting ledge body and castingin in the ceramic wear-resisting block of ledge body local location.Described casting ledge body material is low-alloy steel, and ceramic wear-resisting block main species has aluminium oxide ceramics, zirconia ceramics, silicon carbide ceramics and composite material thereof.Ceramic wear-resisting block cross sectional shape is designed to trapezoidal, and wear-resistant block small end face is concordant with ledge cast(ing) surface, and thickness is 8mm, and centre is provided with through hole, and with slip-off preventing, arrangement pitch 20mm, number of the arrangement is pressed ledge position easy to wear size and determines.
Concrete manufacturing process is: ceramic wear-resisting block is placed in advance and is fixed in the ledge die cavity of the type of having made, and smelts, pours into a mould by the requirement of product material, and liquid metal coating ceramic wear-resistant block completes product casting, can enter the operations such as cleaning and heat treatment subsequently.
The shape to wear-resisting insert can be required according to the ledge properties of product of different structure, size, size designs within the specific limits.
