Description

A kind of high abrasion roller of rolling machine

Technical field

The utility model is related to roll squeezer technical field, specially a kind of high abrasion roller of rolling machine.

Background technology

Roll squeezer also known as squeezing mill, roll mill are that the energy saving grinding of novel concrete that international the mid-80 grows up is set It is standby, have and substitute high energy consumption, efficiency low ball grinding machine pregrinding system, and reduce the function of steel consumption and noise, is suitable for New factory construction, it can also be used to which old factory's technological transformation makes Ball Mill System output increased 30-50%, the material material after extruding 0.08mm fineves account for 20-35% in cake, account for 65-85% less than 2mm, short grained internal structure is full of many micro- because being squeezed Crackle, grindability are greatly improved.Roll surface is welded using thermal reactor, and wearing layer repair is more convenient.

The roller anti-pressure ability on roll squeezer, wearability are poor at present, are further improved.

Utility model content

The purpose of this utility model is to provide a kind of high abrasion roller of rolling machine, to solve to propose in above-mentioned background technology The problem of.

To achieve the above object, the utility model provides the following technical solutions：A kind of high abrasion roller of rolling machine, including the One roller and the second roller, first roller are positive frustum structure；Second roller is inversed taper platform structure, first roller Son and the second roller cooperate；The structure of first roller and the second roller is completely the same, including roll body, in the roll body Chamber is equipped with fixed column and reinforcing rib；The reinforcing rib is welded between fixed column outer wall and roll body inner wall；The outer side roller of the roll body Uniform welding has multiple hemispherical projections on face；Heap is welded with wearing layer on the roll body outer wall.

Preferably, the wearing layer uses high-wear-resistant alloy；The high-wear-resistant alloy is cobalt chromium tungsten hard alloy, described resistance to Mill layer thickness is 2mm-4mm.

Preferably, the height of the hemispherical projections is 3mm-5mm.

Compared with prior art, the utility model has the beneficial effects that：

（1）The utility model novel in structural design, wherein roll body inner cavity is equipped with fixed column and reinforcing rib；Reinforcing rib welds Between fixed column outer wall and roll body inner wall, using this structure, the compressive property of roll body can be improved；Heap is welded on roll body outer wall Wearing layer, and wearing layer uses cobalt chromium tungsten hard alloy, can improve the wearability of roll surface, further extend the use of roller Long lifespan.

（2）In the utility model, uniform welding has multiple hemispherical projections on roll surface on the outside of roll body, can using this structure Improve material squeezing effect.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of high abrasion roller of rolling machine, including first Roller 1 and the second roller 2, first roller 1 are positive frustum structure；Second roller 2 be inversed taper platform structure, described first Roller 1 and the second roller 2 cooperate；The structure of first roller, 1 and second roller 2 is completely the same, including roll body 3, institute It states 3 inner cavity of roll body and is equipped with fixed column 4 and reinforcing rib 5；The reinforcing rib 5 is welded between 3 inner wall of 4 outer wall of fixed column and roll body, Using this structure, the compressive property of roll body can be improved；Uniform welding has multiple hemispherical projections on 3 outside roll surface of the roll body 6；Heap is welded with wearing layer 7 on 3 outer wall of the roll body；Wearing layer 7 uses high-wear-resistant alloy；The high-wear-resistant alloy is that cobalt chromium tungsten is hard Matter alloy, the wear-resisting layer thickness are 2mm-4mm, can improve the wearability of roll surface, and further extend roller uses the longevity Life length.

In the utility model, the height of hemispherical projections 6 is 3mm-5mm.In the utility model, on the outside of roll body on roll surface It is even to be welded with multiple hemispherical projections, material squeezing effect can be improved using this structure.

In conclusion the utility model novel in structural design, wearability and compressive property are good, service life is long, this external enwergy Enough improve material squeezing effect.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
