Abstract
The utility model relates to a metal-based ceramic composite material millstone of a vertical mill machine. The millstone is formed by compositely casting an anti-abrasion ceramic material and high-chromium alloy, wherein the anti-abrasion ceramic material is arranged on the upper surface of the high-chromium alloy and divided into a plurality of spaced anti-abrasion ceramic bars by bar-shaped separation blocks which are arranged on the upper surface of the high-chromium alloy, each anti-abrasion ceramic bar is half wrapped between every two adjacent bar-shaped separation blocks, and the upper surface of the millstone is an arc surface which is sunken from the center to the circumference. The arc surface is in an inward-concave shape, and when a material is milled, the milling time of the material can be maximally increased, so that the material can be adequately milled; the anti-abrasion ceramic material is half wrapped in the high-chromium alloy, so that anti-abrasion ceramic particles in the anti-abrasion ceramic material are non-uniformly wrapped in the high-chromium alloy medium of the millstone, a ceramic phase is combined with a metal phase, the problem of abrasion of a wearable part indirectly caused by bolt connection can be avoided, the abrasion resistance of the millstone can be improved, and the service life of the millstone can be prolonged.
Description
Technical field
The utility model relates to a kind of abrasion-resistant ceramic lining plate of mill, specifically a kind of metal matrix ceramic composites mill for vertical mill.
Background technology
Wear-resistant ceramic is a kind of material take aluminium oxide as main body, additional other rare metal oxide is solvent, form through high temperature sintering, all wear and tear in large plant equipment to be widely used in defeated coal, conveying system, pulverized coal preparation system, ash discharge, dust pelletizing system of the enterprises such as thermoelectricity, iron and steel, smelting, machinery, coal, mine, chemical industry, cement, port and pier etc., such as using in the loading mechanization magazine-less systems such as material iron ore, coal, the positions easy to wear such as version, bucket wheel circular arc wearing plate are reclaimed at stock guide, blanking in concrete position.In the time that cement vertical mill uses, by the rotation of mill and the mill grinding material of exerting pressure, material is broken, grinds between mill and mill, its lining board for grinding discs belongs to vulnerable part, after wear liner, can cause the problems such as yield reducation, quality of products, energy consumption increasing, and too fast wear liner can cause mill running rate to reduce, and metal wastage strengthens, and maintenance cost increases.At present, generally adopt the material such as rich chromium cast iron, alloy casting to form, in the time grinding the stronger material of abrasion wearing and tearing very fast, the life cycle that can not meet the shortest a year guarantees, therefore, urgent need can adapt to various materials, lining board for grinding discs that anti-wear performance is good; And, in actual applications, often make according to the shape of mill the liner plate matching, and be bolted, complete the fixing of liner plate.But in use, produce wearing and tearing thereby connecting bolt can be subject to the impact of material, and then the position easy to wear of indirectly wearing and tearing, do not reach the anti-wear object of expection, and the wearing and tearing meeting of connecting bolt is due to its sealing problem, produces and leaks material phenomenon, impact is normally produced; Along with the wearing and tearing of liner plate, need frequent fastening bolt, this fastening process make the shutdown of grinding machine and start frequent, complicated operation, affects the normal service life of equipment.
Utility model content
Technical problem to be solved in the utility model is that to overcome the wear liner that available technology adopting metal material casts very fast, and liner plate causes the problems such as position easy to wear wearing and tearing, service life are short in use procedure indirectly because of with bolts, provide that a kind of anti-wear performance for vertical mill is good, the metal matrix ceramic composites mill of long service life.
The utility model for addressing the above problem adopted technical scheme is: a kind of metal matrix ceramic composites mill for vertical mill, mill is formed by wear-resistant ceramic material and high-chromium alloy composite casting, described wear-resistant ceramic material is arranged on the upper surface of high-chromium alloy, and the bar shaped spacing block being arranged by high-chromium alloy upper surface is separated into the wear-resistant ceramic bar of multiple spaces, wear-resistant ceramic bar is partly wrapped between two adjacent bar shaped spacing blocks, and upper surface You Qi center to the circumference of described mill is recessed arcwall face.
In the utility model, only adopt wear-resistant ceramic material to become mill with high-chromium alloy composite casting, reduced on the one hand cost of material; On the other hand, the preparation of mill is comparatively simple, and its preparation process is convenient to control.
Mill of the present utility model, one, has the hardness of ceramic material, high-wearing feature, its anti-wear performance is the more than four times of metal material; Its two, there is the toughness of metal material, there is higher metal toughness and resistance to impact; Its three, than tradition use mill lightweight, be easy to construction and installation, save labour intensity; Its four, long service life, has reduced stopping production maintenance frequency, save investment, reduce labour intensity, improved production efficiency.
Beneficial effect:
(1) the upper surface You Qi center of mill is recessed arcwall face to circumference, and arcwall face is the shape of indent, in the time of grinding material, can increase to greatest extent the polished time of material, makes the more abundant of material grinding.
(2) mill is the integrative-structure that wear-resistant ceramic material becomes with high-chromium alloy composite casting, on the rubbing surface of mill, there are multiple wear-resistant ceramic particles, wear-resistant ceramic material is partly wrapped in high-chromium alloy, wear-resistant ceramic particle in wear-resistant ceramic material is wrapped in the high-chromium alloy medium of mill unevenly, ceramic phase and the Metal Phase of material are mutually combined, replacing traditional use bolt is fixed the mill of liner plate and vertical mill, avoid the race material of traditional vertical mill and leaked material phenomenon, can also avoid the problem that indirectly causes damageable zone wearing and tearing because of with bolts, greatly improve the wearability of mill, extend its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of mill in the utility model;
Fig. 2 is the schematic diagram along A-A line in Fig. 1.
Reference numeral: 1, wear-resistant ceramic material, 2, high-chromium alloy, 3, wear-resistant ceramic bar, 4, bar shaped spacing block.
The specific embodiment
As depicted in figs. 1 and 2, a kind of metal matrix ceramic composites mill for vertical mill, mill is formed by wear-resistant ceramic material 1 and high-chromium alloy 2 composite castings, described wear-resistant ceramic material 1 is arranged on the upper surface of high-chromium alloy 2, and be separated into the wear-resistant ceramic bar 3 of multiple spaces by the bar shaped spacing block 4 of high-chromium alloy 2 upper surface settings, wear-resistant ceramic bar 3 half is wrapped between two adjacent bar shaped spacing blocks 4, as shown in Figure 2, upper surface You Qi center to the circumference of described mill is recessed arcwall face, when grinding material, can increase to greatest extent the polished time of material, make the more abundant of material grinding.
In the utility model, mill is formed by wear-resistant ceramic material 1 and high-chromium alloy 2 composite castings, without using bolt that the mill of liner plate and vertical mill is fixed, thereby has avoided the race material of traditional vertical mill and has leaked material phenomenon; Mill is a complete entirety, and when casting, high-chromium alloy can infiltrate between the ceramic particle of wear-resistant ceramic material, and ceramic particle is wrapped up, and ceramic phase and Metal Phase are uniformly distributed, and has greatly improved the wearability of mill, has extended its service life; This mill has ceramic high strength, high temperature resistant, anti-oxidation characteristics concurrently, has again plasticity and the shock resistance of metal.
