Abstract
The utility model relates to a wear-resistant roll sleeve of a rolling press, which comprises a roll sleeve body; and a hard alloy rod is cast on the outer surface of the roll sleeve body. The hard alloy rod with high hardness is cast on the rolling surface of the wear-resistant roll sleeve of the rolling press, the service life of the roll sleeve can be greatly prolonged, i.e. generally 1 to 3 times of that of a traditional grinding roll; a centrifugal casting process is adopted, the tissue of a casting is compact and uniform, and the structure is firm; and the cast roll sleeve can make up for the technical defects brought by a rolling surface welding method and improves the service life of the roll sleeve, so that the rolling press has higher operation rate.
Description
Technical field
The utility model relates to a kind of wear-resisting roller shell, the wear-resisting roller shell of particularly a kind of roll squeezer.
Background technology
Roll squeezer is as the main process equipment of pre-grinding, combination grinding and final grinding system, its engineering reliability and power savings advantages for users cognition and acceptance.But homemade roll squeezer development is subjected to the restriction in its roll surface life-span always, and roll surface can produce heavy wear in the process that long-term extruding is pulverized, so the raising in its performance and life-span is the target that the practitioner pursues always as the key position of roll squeezer running.
Roll squeezer comprises that two speed are identical, the roller of relative motion, material is unloaded by roller top spout, enter in the slit between roller, under the effect of high pressure abrasive power (roll gap pressure is between 50～300MPa), the material of nipping is squeezed, and has become closely knit but is full of the flat material cake of crackle.From the working condition of roll squeezer as can be seen, roll surface wear is actually roll surface high stress material abrasion and the coefficient result of roll surface subsurface stratum fatigue wear, and this just requires roll surface to have higher hardness and toughness.
For improving the wearability of roll squeezer roll surface, generally adopt the method for making roll shaft cylindrical build-up wear-resistant welding wire in the refined alloy forging at present.Different quality of parent material need be selected different welding wires for use with the industrial and mineral condition, and welding material and selection of Welding are improper, are easy to cause the situations such as localized delamination, fatigue rupture of roll surface, need the off-line reparation when serious, and running rate is low.And it is under the roll surface normal wear situation, also need regular online reparation, and comparatively frequent.Therefore, the built-up welding roller shell has improved the operating cost of manufacturing enterprise to a certain extent, and greatly reduces production efficiency.
Summary of the invention
The utility model provides a kind of wear-resisting roller shell of roll squeezer that can increase substantially surface abrasion resistance and 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: the wear-resisting roller shell of a kind of roll squeezer, comprise the roller shell body, and castingin has hard alloy bar on the outer surface of described roller shell body.
The utility model can also adopt following technical scheme:
Described hard alloy bar exceeds the outer surface of described roller shell body.
The length of described hard alloy bar has at least two kinds of specifications, and is staggered in described roller shell body.
Described roller shell body is made by ultra-high manganese steel or potassium steel.
Described hard alloy bar is a cylinder, and described cylindrical diameter is 5～50mm.
Described hard alloy bar is the hexagonal prism body, and the circumscribed circle diameter of described hexagonal prism body is 5～50mm.
Advantage and the good effect that the utlity model has are: 1) hard alloy bar of roll surface castingin high rigidity can increase substantially its service life, is generally 1～3 times of current grinding roller life-span; 2) adopt centrifugal casting technique, foundry goods dense structure is even, and is firm in structure; This castingin roller shell can remedy the technological deficiency that the roll surface overlaying method is brought, and has improved the service life of roller shell, thereby has guaranteed that roll squeezer has higher running rate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, first hard alloy bar, 2, second hard alloy bar, 3, the roller shell 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 wear-resisting roller shell of a kind of roll squeezer, castingin has first hard alloy bar 1 of high rigidity and second hard alloy bar, 2, the first hard alloy bars 1 and second hard alloy bar 2 all to exceed the some millimeters in mother metal 4 surfaces on the outer surface of roller shell body 3, to increase the frictional force of roll surface.Particular design is carried out according to the specification and the roll surface wearing situation of roller shell in the arrangement scheme of first hard alloy bar 1 and second hard alloy bar 2, gap.For preventing that first hard alloy bar 1 and 2 pairs of roller shell bodies of second hard alloy bar 3 from producing stress and concentrating, its length adopts two kinds of specifications, and is staggered in roller shell body 3.The utility model is for preventing that hard alloy bar from producing stress to mother metal and concentrating, and its length has been not limited to two kinds of specifications, and two or more specifications can also be arranged, and is staggered in mother metal.
The utility model has adopted centrifugal casting technique, before the centrifugal casting, and fixing hard alloy bar in the centrifugal casting mould at first, mould inner surface spraying one deck heat-resistant paint.And then liquid mother metal poured in the centrifugal casting machine, solidify after the cooling the foundry goods demoulding.Again with foundry goods through quenching, after the tempering, carrying out fine finishining, get final product product.
The roller shell of making under these process conditions can increase substantially service life, is generally 1～3 times of current roller shell life-span.
The profile of above-mentioned hard alloy bar is cylinder or hexagonal prism body, and its diameter or circumscribed circle diameter are 5～50mm.The mother metal of roller shell body 3 is ultra-high manganese steel or potassium steel.
