The roller sleeve is provided with a sleeve body (1), wherein the sleeve body (1) is made of alloy steel; grooves (2) are formed in the outer peripheral face of the sleeve body (1) in an axial direction; the grooves (2) are uniformly distributed along the periphery; a linear bead (3) is formed between every two adjacent grooves (2); the surface hardness of the sleeve body (1) is HRC60-64; and the center hardness of the sleeve body (1) is HRC28-40. According to the roller sleeve disclosed by the utility model, welding cracks generated by surfacing can be effectively avoided; the roller sleeve has good wear resistance and long service life, can ensure the efficiency and the effect of roller pressing and has the characteristics of simple structure, easiness in machining and manufacturing, low cost, convenience ini exchanging and the like.
Description
Technical field
The utility model belongs to the roll squeezer technical field, specifically, and the particularly roller shell on roll squeezer.
Background technology
Roll squeezer has been widely used in the cement of cement industry and the grinding of raw material, is the another Important Techmical Progress after the predecomposition technology outside kiln.The application of roll squeezer has not only reduced power consumption, and has improved mill output, product quality.But its compression roller roll surface wearing problem usually affects normal production, enjoys developer and user to pay attention to always.
For the compression roller of roll squeezer, it is one of critical component of roll squeezer, because material is to carry out grinding by the heavily stressed extruding of compression roller, so the wearing and tearing of compression roller are inevitably, so the technical indicator that the life-span of compression roller is applying unit to be concerned about very much.
The classification of compression roller can be divided into solid forging roller, roll shaft+roller shell combination roller by version; Press roll surface decorative pattern shape, can be divided into a word line, the wear-resisting decorative pattern of prismatic stiffened particle, prismatic without hard particle abrasion resistant decorative pattern, circular point shape hard particle abrasion resistant decorative pattern, the wear-resisting decorative pattern of zigzag, the wear-resisting decorative pattern of " people " font, the wear-resisting decorative pattern of corynebacterium.
At present, the wear-resisting decorative pattern of various compression roller roll surfaces (as a word line, prismatic line, chevron etc.) is main, and what adopt is structure at roll surface build-up wear-resistant material, because the process characteristic of built-up welding has determined that there is weld crack in wear-resisting decorative pattern, and weld crack has directly affected wearability and the service life of wearing layer.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can effectively improve the roller sleeve of roller press in wearability and service life.
The technical solution of the utility model is as follows: a kind of roller sleeve of roller press, has body (1), described body (1) is made by steel alloy, be provided with vertically groove (2) on the outer circumference surface of body (1), described groove (2) is pressed even circumferential and is distributed, and forms yi word pattern fin (3) between two adjacent grooves (2); The case hardness of described body (1) is HRC60-64, and the centre hardness of body (1) is HRC28-40.
The utility model is made by high strength, high tenacity, wear-resisting, corrosion-resistant, low temperature resistant, high temperature resistant, non-magnetic steel alloy, the wear-resisting decorative pattern of cover surface is that the yi word pattern fin is not the high-abrasive material of built-up welding, but have a style of one's own with roller shell, avoided the weld crack that produces because of built-up welding.The cover surface has higher hardness through special thermal treatment, and hardness reaches HRC60-64; Simultaneously centre hardness is HRC28-40, and heart section has mechanical performance and intensity preferably, and the wearability of roller shell is good like this, long service life, and through practical proof, be more than the twice of traditional structure the service life of roller shell.The utility model is set on roll shaft by interference fit, after roll surface wear-resisting decorative pattern wearing and tearing, can be according to a conventional method carries out online build-up wear-resistant decorative pattern, the service life of again having improved roller shell at the user scene.After roll surface wearing is scrapped, only need to change roller shell, roll shaft still can continue to use on the one hand, has saved cost; On the other hand, roller shell is changed convenient, can effectively shorten user's downtime.
The degree of depth (H) of described groove (2) is 5-15mm, and the width of groove (2) increases gradually from bottom land toward the direction of notch, and the width (L1) at groove (2) notch place is 10-25mm.Processing and fabricating is easy on the one hand for above structure, and on the other hand, shape and the specifications design of groove are reasonable, can either prevent the fin damage that breaks under high pressure, can take into account again and be with the material ability, makes the efficient of roll-in and effect all secure.
As preferably, for the ease of input and output material and band material, be rounded down between the top of described groove (2) two side and the end face of fin (3) or the oblique angle of 45 °.
The width (L2) of described fin (3) end face is 10-25mm.The width of fin end face is too small, easily causes fin to damage under high pressure; The width of fin end face is excessive, and band material ability weakens, and can affect efficient and the effect of roll-in.Therefore, the width of fin end face is advisable with 10-25mm, can take into account intensity and the band material ability of fin.
As preferably, described groove (2) is groove, and the two ends of this groove (2) connect the corresponding end face of bodies (1).
As preferably, the cell wall of described groove (2) end is arc surface, form wall (4) altogether between the end face of this arc surface and body (1) corresponding end, described width (L3) minimum of wall (4) end face altogether, and the width (L3) of wall (4) end face is 2-10mm altogether.
Beneficial effect: the utility model can effectively be avoided the weld crack that produces because of built-up welding, and wearability is good, and long service life can guarantee efficient and the effect of roll-in to have the characteristics such as simple in structure, that processing and fabricating is easy, cost is low, replacing is convenient.
