Abstract
The utility model relates to a metal-ceramic composite wear-resistant grinding roller sleeve, which can effectively solve the problems of simultaneously having high wear resistance and toughness and remarkably prolonging the service life of parts. The roller sleeve is a circular sleeve body composed of split roller sleeves, each split roller sleeve comprises a ceramic prefabricated part and high alloy wear-resistant metal, the ceramic prefabricated parts are embedded into the split roller sleeves, the high alloy wear-resistant metal is filled into the remaining portion inside the split roller sleeves, and the ceramic prefabricated parts and the high alloy wear-resistant metal are firmly combined into a whole. The roller sleeve as a novel roller sleeve designed based on principles and characteristics of metal matrix composite materials uses high hardness of ceramic and high toughness of metal materials to obtain high wear resistance and toughness, is simple in structure, novel, unique, long in service life and low in cost, prolongs the service life of the roller sleeve doubly to triply, and lowers cost by more than 20%.
Description
Technical field
The utility model relates to a kind of metal-ceramic complex abrasion-proof roller roller shell.
Background technology
In industries such as metallurgy, mine, electric power, building materials, be used for pulverizing in the grinding machine with mixed prepared material, the roller roller shell had both been required high-wearing feature, high obdurability is arranged again.Under such operating mode, homogenous material often is difficult to satisfy simultaneously above-mentioned requirements.
At present, wear-resisting roller roller shell, by material and technology, can divide following three classes substantially: casting antifriction alloy white cast-iron: this wherein is divided into rich chromium cast iron and ni-hard cast iron again, substantially all be to adopt traditional casting technique, utilize the high rigidity carbide of himself to improve wearability.Hardfacing: the metal microstructure exquisiteness via hard-facing is handled, can form quite stable and hard carbide, show very wear-resisting characteristic.Carbide alloy-cast iron castingin complex technique: characteristics such as carbide alloy has the hardness height, and hardness is even, multiple function such as it is wear-resisting that its surface has concurrently, heat-resisting, anti-oxidant.Casting is that to utilize the high rigidity carbide to realize wear-resisting with built-up welding essence, improve carbide quantity natural energy and improve wearability, yet the counter productive that quantity is brought is directly to reduce toughness more.Carbide alloy imbedding process, wearability are with raising, but its cost is too high.Therefore imperative to the reform of roller roller shell.
Summary of the invention
At above-mentioned situation, for overcoming the defective of prior art, the purpose of this utility model just is to provide a kind of metal-ceramic complex abrasion-proof roller roller shell, can effectively solve wear-resisting roller roller shell and can have high wearability and obdurability simultaneously, increases substantially the parts problem in service life.
The technical solution of the utility model is, the circular body that the utility model is made up of the distinguish roller shell, each distinguish roller shell comprises ceramics preparative spare and high alloy antifriction metal (AFM), ceramics preparative spare embeds in the distinguish roller shell, remainder is filled with the high alloy antifriction metal (AFM) in the distinguish roller shell, and ceramics preparative spare is an one with high alloy antifriction metal (AFM) strong bonded.
Useful technique effect of the present utility model is, the present roller roller shell that uses, be based on wear-resistant metal material, if adopt single material often to be difficult to satisfy simultaneously the requirement of above-mentioned more high-wearing feature, in the last few years, by the broad development of metal-base composites technology, particularly wear resistance castings is after ceramic reinforced, its anti-wear performance increases substantially, and to prolonging the mo(u)lded piece life-span, improves equipment operation rate and has great importance.The utility model just is based on a kind of novel roller shell of the principle and the characteristics design of metal-base composites (MMC), utilize the high rigidity of pottery and the high tenacity of metal material, obtain high-wearing feature and toughness, simple in structure, novel unique, long service life, cost is low, roller shell prolongs one to two times service life, and cost reduces more than 20%.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model side view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done detailed explanation.
By Fig. 1-shown in Figure 2, the circular body that the utility model is made up of distinguish roller shell 1, each distinguish roller shell 1 comprises ceramics preparative spare 2 and high alloy antifriction metal (AFM) 3, ceramics preparative spare 2 embeds in the distinguish roller shell 1, remainder is filled with high alloy antifriction metal (AFM) 3 in the distinguish roller shell 1, and ceramics preparative spare 2 is an one with high alloy antifriction metal (AFM) 3 strong bonded.
In order to guarantee result of use, fixing hole 4 is arranged on the ceramics preparative spare 2, the high alloy antifriction metal (AFM) fixed leg that is connected as a single entity with high alloy antifriction metal (AFM) 3 is arranged in the fixing hole 4.
Said ceramics preparative spare 2 adopts the metallurgical binding mode to be connected with high alloy antifriction metal (AFM) 3, ceramics preparative spare 2 combines with high alloy antifriction metal (AFM) 3 and forms the cermet complex, since be that its bond strength is higher with metallurgical mode combination, ceramic difficult drop-off in the roller shell use.
Said ceramics preparative spare 2 is the tire corrugated, antifriction metal (AFM) and Ceramic Composite, as ceramics preparative spare, the utility model roller shell occurs with " wheel tread " structure, use for reference tire wear and roller shell " wavy " inefficacy form, thereby structure with improve wearability in shape, prolong the utility model roller shell service life.
When the utility model was produced, at first antifriction metal (AFM) and Ceramic Composite as ceramics preparative spare, adopted tradition or Special Processes of Metal Castings technology with in prefabricated component " embedding " the muller roller shell then.Prefabricated component ceramic segment volume accounts for 40～80% of circular body, and high alloy antifriction metal (AFM) 3 accounts for 20～60% of circular body, and the prefabricated component pottery is selected high tenacity high rigidity oxide or carbide ceramics for use.The prefabricated component shape adopts " wheel tread ".Distinguish roller shell 1 is spliced into the circle back and adopts the mechanical bond mode to be connected with wear resistant roll.
The utility model is the roller that adopts ceramic enhancing technology to produce, and can have high wearability and obdurability simultaneously, can increase substantially the service life of parts, prolongs one to two times service life, and cost is low.
