Description
Technical field
The utility model relates to a kind of shaped steel transfer roller, especially a kind of passive transfer roller structure.
Background technology
Transfer roller quality is becoming the major influence factors of steel rolling Surface of profile quality, because wearing and tearing make transfer roller surface occur the defect such as rectangle groove or " V " type groove, making it when transmitting steel rolling shaped steel, causing shaped steel surface to occur the mass defect such as microprotrusion, crackle.When transfer roller rotates, its driving surface contacts with shaped steel, rely on friction force conveying shaped steel, transfer roller driving surface usually causes inefficacy or scraps because surface abrasion occurs too early partial failure, not only affect the transport efficiency of shaped steel, affect the surface quality of shaped steel, whole complete equipment manufacturing line stop production to overhaul time serious simultaneously.
Publication number is the Chinese invention patent application " a kind of table roller with transmission and binder supporting role " that provide of 203679431, and the structure that the method is made up of rod body and roll shaft, rod body end is installed sprocket wheel and driven roller turn.
Publication number is the Chinese invention patent application " metal and special-shaped ceramics combination roller " that provide of 203532511, and the method is this extracorporeal set of metal rolls special-shaped ceramics, filling flexible packed layer between metal body and special-shaped ceramics.
All have the roll or conveying roller report that adopt nickel-based self-fluxing alloy built-up welding strengthening at many places open source information and patent, it is serious for existing the impact of hot-rolled steel section surface quality based on overlay surface crackle; Also the built-up welding of bibliographical information cobalt base self-fluxing alloy is had to strengthen, because the application of cobalt base self-fluxing alloy overlay surface high temperature wear resistant limited capacity is limited.In addition, about HVAF or plasma spraying metal metal-cermic coating, conveying roller is strengthened, metal ceramics used adds WC composition primarily of nickel-based self-fluxing alloy or cobalt base self-fluxing alloy, and the bonding properties of coating still affects the key of roll under abrasion environment or conveying roller.
Summary of the invention
The purpose of this utility model is the deficiency overcome in prior art, provides that a kind of structure is simple, function admirable, stablizes, easy and simple to handle, anti abrasive transfer roller structure.
For achieving the above object, the utility model transfer roller structure comprises: the hollow roller of medium-carbon steel, roller core, cushion layer and alloy driving surface; The axle center place of the hollow roller of medium-carbon steel is roller core, and the two integrally welded formation transfer roller body, transfer roller body both ends outside face has cushion layer, and the outside face of cushion layer has alloy driving surface.
Described cushion layer is by the shaping 1Cr of plasma cladding
18ni
9ti layer, transfer roller radial direction deposition 2 ~ 3mm thickness.
Described alloy driving surface is the 1Cr of plasma cladding on the buffer layer
18ni
9ti+NiCrMoCo-WC alloy.
Beneficial effect, wear-resistant transfer roller structure of the present invention, roll body and roller core are designed to one, effectively realize self rolling, transmission and support function.The shaping 1Cr of plasma cladding
18ni
9ti cushion layer can discharge the stress produced in driving surface manufacture and service process very well, cushioning layer material and roller body and driving surface material compatibility good, form the transfer roller with functionally gradient material (FGM) function.Plasma cladding 1Cr
18ni
9the driving surface hardness of Ti+NiCrMoCo-WC alloy forming is high, has good abrasion resistance properties.Transfer roller driving surface is distributed in two ends of roller, changes other one end and continues to use, extend the service life of transfer roller after facilitating roller one end to lose efficacy, reduce the replacement cycle, the present invention has wide range of applications, and can be applied to steel rolling shaped steel transfer roller, and other relevant transfer roller.
