Abstract
The utility model relates to a wear-resistant grinding roller, which is characterized in that: the outer surface of an annular grinding roller main body is in a shape of a cone frustum, the outer surface of the grinding roller main body is embedded and cast with hard alloy blocks one by one, the hard alloy blocks embedded and cast on the outer surface of the grinding roller main body are circumferentially arranged in six rows, the diameters of the two rows of the hard alloy blocks near a big end of the grinding roller main body are larger than an interval between adjacent hard alloy blocks, the diameters of the middle two rows of the hard alloy blocks are equal to the interval between the adjacent hard alloy blocks, and the diameters of the last two rows of the hard alloy blocks are smaller than the interval between the adjacent hard alloy blocks, therefore the problem of uniform abrasion of the grinding roller is solved and the service life and the grinding quality are improved; furthermore, the high-hardness hard alloy blocks of tungsten and cobalt types are utilized to greatly improve the service life. The grinding roller main body is made of intermediate and low alloy steel with better toughness, thus not only being convenient for processing but also improving the impact-resistance of the grinding roller; and the wear-resistant grinding roller has the advantages of simple technique, firm structure, easy manufacture and low cost.
Description
Technical field
The utility model relates to a kind of ring-roller mill that is used for material grinding, especially a kind of abrasive roller.
Background technology
Restrictions zero, problems such as component wear is fast, the life-span is short, maintenance cost height that the use of present homemade Vertical Mill is subjected to always.Grinding roller can produce heavy wear in long-term mill processes, so the raising in the performance of its high-abrasive material and service life is the target that the designer pursues always as the critical component of Vertical Mill.
The castingin grinding roller is gone into the mosaic block of high rigidity, the life-span that can significantly improve grinding roller at the surperficial castingin of tough main body.The patent No. is that the utility model of ZL01242782.9 discloses that a kind of what be inlaid with proper alignment is that the mosaic block of main hard material is (to add chromium with TiC, manganese, nickel, elements such as iron are adhesive, through vacuum-sintering and heat treatment and the mosaic block that makes), its structure is: the outer surface of annular grinding roller body is circular cone shape, be inlaid with the hard alloy blocks of circumferential array one by one at this external surface of grinding roller, every row mosaic block is adjacent between the row and is staggered, mosaic block is mounted on the roller surface body equably, the mosaic block diameter makes mosaic block continuous along the projection on the roller direction of advance more than or equal to the gap between the adjacent column mosaic block.But this grinding roller is in use found the very inhomogeneous of roller surface wearing and tearing, near the grinding roller serious wear of big end, and the product quality that influences service life and mill.
Summary of the invention
The utility model provides a kind of abrasive roller of effective, long service life for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of abrasive roller, comprise that outer surface is the annular grinding roller body of circular cone shape, the castingin hard alloy blocks one by one at this external surface of grinding roller, the hard alloy blocks of described this external surface of grinding roller castingin circumferentially is provided with six rows, arrange the hard alloy blocks diameters greater than adjacent hard alloy blocks spacing near two of the big end of grinding roller body, middle two row's hard alloy blocks diameters equal adjacent hard alloy blocks spacing, and last two row's hard alloy blocks diameters are less than adjacent hard alloy blocks spacing.
The utility model can also adopt following technical scheme:
Described hard alloy blocks is a cylinder.
Described hard alloy blocks is the hexagonal prism body.
Described hard alloy blocks is the W-Co kind carbide alloy, and the grinding roller body is a middle-low alloy steel.
Advantage and the good effect that the utlity model has are:
Because the density at this external surface of grinding roller imbedding hard alloy piece is stepping, hard alloy blocks density maximum near the big end castingin of grinding roller body, away from the hard alloy blocks density minimum of the big end castingin of grinding roller body, thereby solved the uneven problem of grinding roller wearing and tearing; Again because the carbide alloy of this external surface of grinding roller castingin W-Co kind high rigidity can increase substantially its service life, be generally 2～3 times of known grinding roller life-span, and the grinding roller body adopts the middle-low alloy steel with better toughness, not only is convenient to process but also can improve the shock resistance of grinding roller; In addition the utility model also have technology simple, firm in structure, be easy to make, advantage that cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A revolved sectional view of Fig. 1.
Among the figure: 1, hard alloy blocks; 2, grinding roller body; 3, the big end of grinding roller body.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, the outer surface of annular grinding roller body 2 is circular cone shape, at this external surface of grinding roller castingin hard alloy blocks 1 is one by one arranged.The hard alloy blocks of described this external surface of grinding roller castingin circumferentially is provided with six rows, arrange the hard alloy blocks diameters greater than adjacent hard alloy blocks spacing near two of the big end 3 of grinding roller body, middle two row's hard alloy blocks diameters equal adjacent hard alloy blocks spacing, and last two row's hard alloy blocks diameters are less than adjacent hard alloy blocks spacing.Described hard alloy blocks is a cylinder, also can be the hexagonal prism body, and its effect is identical, has solved the uneven problem of grinding roller wearing and tearing like this; Described hard alloy blocks is the W-Co kind carbide alloy, can increase substantially its service life, is generally 2～3 times of known grinding roller life-span; The grinding roller body is a middle-low alloy steel, and it has the middle-low alloy steel of better toughness, not only is convenient to process but also can improve the shock resistance of grinding roller; In addition the utility model also have technology simple, firm in structure, be easy to make, advantage that cost is low.
