Abstract
The invention discloses a roll face of a roller press, which comprises large studs, first small studs and second small studs, wherein the large studs, the first small studs and the second small studs are distributed on the roll face of the roller press in a staggered manner uniformly, each of the first small studs is arranged at the edge of the roll face and located in a space between each two large studs, and the second small studs are arranged at the outer edge of the roll face. The whole roll face can be protected against abrasion, the service life of the whole roll face is prolonged, the manufacturing cost and the maintenance cost thereof are lowered, the running rate of a roll is increased effectively, and the edges of the roll can be protected effectively for long-term use. In addition, after the roll is provided with the roll face, the service life of the roll can be prolonged by 15%, and the manufacturing cost thereof is reduced by 8%.
Description
Technical field
The present invention relates to a kind of roll surface of roller press, relate in particular to a kind of roller roll surface for industry roll-in milling equipment roll squeezers such as building material cement, metallurgical mine, coal, chemical industry, belong to roll squeezer technical field.
Background technology
In the time of roll squeezer (also claiming high-pressure roller mill) roller tribulation grind materials, as slag, iron ore, quartz mine etc., the roller roll surface of roll squeezer adopts the method for tungsten carbide button's stud to ensure its wearability conventionally.But there is not effective guard method at the edge of roller always, this makes the service life at roller edge more much lower than other position, and the wear-resistant protection at roller edge remains the large technological difficulties of one in roller Anti-wear Technology.Past; in order to protect at pair of rollers edge; conventionally the method adopting is at roller edge built-up welding one deck high-abrasive material; but the service life of adopting the roller corner producing is in this way still very low; need regular built-up welding; the number of times of repeated overlaying weldability is limited, often falls piece phenomenon because corner occurs weld crack, can not meet instructions for use.
China Patent Publication No. is CN201586536U, and denomination of invention discloses a kind of wear-proof armor layer for roller end surface for " wear-proof armor layer for roller end surface ", comprises roller shell, is provided with annular groove on the end face of roller shell, and in annular groove, correspondence is provided with abrasionproof mechanism.Although this device can solve end wear, the method still can not be separated fast roller corner wear problem effectively; And it is wear-resisting to use mushroom head on roll surface to carry out, and has only provided a theoretic concept, concrete implement and service condition is described in detail.
China Patent Publication No. is CN201969585U; denomination of invention discloses a kind of method that adopts gusset or protruding wear-resistant block pair of rollers edge to carry out abrasionproof protection for " a kind of roller with corner protection "; after wearing and tearing, change; there is processing difficulties in this method; if gusset and the bad extruding force that just can not bear material of protruding wear-resistant block crudy, damage.
In sum, do not find so far a kind of can pair of rollers edge the effective mode of protection.
Summary of the invention
The object of the invention is to: a kind of roll surface of roller press is provided; solve the technical problem that existing roller of rolling machine edge wearability is not good, service life is short; effectively protect, improve the wearability at roller edge by roll surface of roller press pair of rollers of the present invention edge; extend the service life of edge and even whole roller, thereby can effectively solve above-mentioned problems of the prior art.
The object of the invention is to realize by following technical proposals: a kind of roll surface of roller press, comprise that dislocation is uniformly clouded in the large stud on roll surface, a little stud and No. two little studs, a described little stud is located on the room between the large stud of roll surface edge two, and No. two little studs are located at the outward flange of roll surface.
As a kind of optimal way, wherein: more than the densely covered circle of the even dislocation of described No. two little studs or encloses.
As further preferred embodiment, appearing of described No. two little studs is highly less than large stud; Appearing of a described little stud is highly less than or equal to the height of appearing of large stud.
As optimal way, the diameter of described large stud is φ 10～φ 30mm, and it is appeared is highly 0～20mm.
As optimal way, the diameter of a described little stud is φ 3～φ 20mm, and it is appeared is highly 0～20mm.
As optimal way, the diameter of described No. two little studs is φ 3～φ 20mm, and it is appeared is 0～15mm.
Described roll surface is that high strength steel is made, and described large stud, a little stud and No. two little studs are that carbide alloy is made.
In the present invention, the effect of part is as follows:
A little stud and No. two little studs: make the layout of stud closeer, the manufacturing cost of little stud is lower, has reduced the manufacturing cost of roll surface, and the setting of little stud, make the life-span at roll surface edge the same with the life-span at roll surface middle part, thus the service life of having improved whole roll surface.
Compared with prior art; beneficial effect of the present invention: adopt roll surface of roller press of the present invention; make whole roll surface can obtain wear-resistant protection; improve the service life of whole roll surface; reduce manufacturing cost and the maintenance cost of roll surface, effectively improved the running rate of roller, the reliable and effective protection in pair of rollers edge of long-term use energy; use after this roll surface and can improve and reach 15% service life, reduce manufacturing cost and reach 8%.
Brief description of the drawings
Fig. 1 is the structural representation of roll surface of roller press embodiment 1 of the present invention;
Fig. 2 is the side structure schematic diagram of Fig. 1.
In figure, 1-roll surface, the large stud of 2-, little stud of 3-, No. bis-little studs of 4-.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
Disclosed all features in this description, or step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can combine by any way, unless narration especially, all can be replaced by other equivalences or the alternative features with similar object,, unless narration especially, an embodiment in a series of equivalences of each feature or similar characteristics.
Roll surface of roller press of the present invention comprises that dislocation is uniformly clouded in large stud on roll surface 12, pillar nail 3 and No. two pillars nails 4, on described pillar nail 3 rooms of being located between the roll surface 1 large stud 2 of edge two, No. two pillars nail 4 is located at the outward flange of roll surface 1, and No. two pillar nails 4 are a gather circle or more than a circle of dislocation evenly.Described roll surface is made up of high strength steel, and described large stud, a little stud and No. two little studs are made by carbide alloy.
