Description

A kind of roll squeezer alloy roller shell

Technical field

This practicality belongs to roll squeezer technical field, is specifically related to a kind of roll squeezer alloy roller shell.

Background technology

Roll squeezer is widely used in the grinding of cement and raw material etc., the application of roll squeezer, not only reduces power consumption, Er Qieti High mill output, product quality.Owing to material is to carry out grinding by the extruding of pressure roller, therefore roller surface abrasion is not Evitable, so the life-span of pressure roller is design, manufactures and use unit very concern, enjoy manufacturer and use always Family is paid attention to.

The pressure roller of roll squeezer is overall in early days, is machined with decorative pattern at roller surface, when decorative pattern heavy wear can not use Whole pressure roller must be changed, cause and greatly waste.

Pressure roller is divided into roller shell and axle two parts the most mostly, and roller shell is built-up welding on the surface of cast iron liners or forging lining Hardened layer and decorative pattern, this roller shell there is also clearly disadvantageous, is mainly manifested in:

(1) wearing layer thinner thickness, easy to wear fall, after abrasion will built-up welding again, longer downtime need to be spent, impact The productivity ratio of roll squeezer

(2) built-up welding can produce impact to the life-span of lining repeatedly, reduces the service life of roller shell.

(3) the bonding strength deficiency between wearing layer and lining can cause roller shell face checking, be full of cracks, scaling or delamination etc. Phenomenon, has a strong impact on the service life of roller shell.

(4) produce and maintenance efficiency is low and quality is difficult to ensure.

Summary of the invention

Short for solving existing roller shell wear time, it is easily generated the deficiencies such as cracking, be full of cracks, scaling or delamination, this reality in using High by a kind of production efficiency of novel offer, wearability is good and the roller sleeve of roller press of length in service life.

A kind of roll squeezer alloy roller shell, including lining and wearing layer, including lining, wearing layer outside, at lining and wear-resisting Having a transition zone, lining, transition zone and wearing layer in the middle of layer is an entirety, and organizational structure and the performance of transition zone are all located at lining And between wearing layer.

Wearing layer is the high-alloy steel of special composition, and hardness is high, and thickness is 40-50mm, on the one hand ensures that roller shell has enough Wearability, prevent again high-abrasive material from using simultaneously and too much cause waste.

Lining uses high-carbon steel, good combination property.

Transition zone can be to be used second pouring, natural shape in one-time formed centrifugal casting process by wearing layer and lining Become, first pour into a mould wearing layer, after wearing layer cast terminates in 1.5-2.5 minute, now crystallization and freezing, interior outside wearing layer Portion, also in liquid condition, starts to pour into a mould lining, makes wearing layer and hub sections fusion form the transition zone of 25-40mm thickness, The time interval poured into a mould such as lining and wearing layer is the shortest, and very little, wearing layer thickness is little, transition for the part of wearing layer crystallization and freezing The thickness of layer is big, it is impossible to ensure that roller shell has enough wearabilities, and the time interval poured into a mould such as lining and wearing layer is oversize, intermediate layer Thickness is little, it is impossible to ensure there are enough connections between lining and wearing layer tissue and smooth performance transition and wearing layer and lining Intensity.

Transition zone may also be by individually pouring into a mould formation, the most first pours into a mould wearing layer, then pours into a mould transition zone, then pour into a mould lining Set, the THICKNESS CONTROL of transition zone is between 25-40mm.

The organizational structure of transition zone and performance are all located between lining and wearing layer, it is ensured that lining and wearing layer are tied effectively It is combined, between wearing layer and lining, has certain bonding strength, improve the physical life of roller shell.

There is decorative pattern on the surface of wearing layer, for making decorative pattern have preferable wearability and intensity, the width of decorative pattern opening part and flower The ratio of the degree of depth of stricture of vagina is between 1.7-1.9.

Beneficial effect

1, lining, transition zone, wearing layer and decorative pattern one-shot forming, production efficiency is high；

2, roller shell wearability is good.

3, have certain thickness transition zone, make lining and wearing layer tissue and smooth performance transition, wearing layer and lining it Between have enough bonding strengths, even if wearing layer goes out relatively macrolesion and also will not cause roller shell and significantly affect, the roller shell life-span carries High more than 1.5 times.

4, maintenance and use cost are low.

In figure: 1, lining；2, wearing layer；3, transition zone；4, decorative pattern.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Embodiment 1: a kind of roll squeezer alloy roller shell as depicted in figs. 1 and 2, including lining 1 and wearing layer 2, lining 1 exists In, outside, have a transition zone 3, lining 1, transition zone 3 and wearing layer 2 in the centre of lining 1 and wearing layer 2 be one whole to wearing layer 2 Body, the organizational structure of transition zone 3 and performance are all located between lining 1 and wearing layer 2.

Wearing layer 2 is the high-alloy steel of special composition, and hardness is high, and thickness is 40-50mm, on the one hand makes roller shell have enough Wearability, prevents again high-abrasive material from using simultaneously and too much causes waste.

Lining 1 uses high-carbon steel, good combination property.

Transition zone 3 can be by wearing layer 2 and lining 1 use in second pouring, one-time formed centrifugal casting process from So being formed, first cast wearing layer 2, after wearing layer 2 cast terminates in 1.5-2.5 minute, now wearing layer 2 is outside crystallizes Solidification, inside, also in liquid condition, start to pour into a mould lining 1, make wearing layer 2 and lining 1 partially fused formation 25-40mm thickness Transition zone 3, the time interval poured into a mould such as lining 1 and wearing layer 2 is the shortest, and the part of wearing layer 2 crystallization and freezing is very little, wear-resisting Layer 2 thickness are little, and the thickness of transition zone 3 is big, it is impossible to ensure that roller shell has enough wearabilities, as lining 1 and wearing layer 2 pour into a mould time Between be spaced oversize, intermediate layer 3 thickness is little, it is impossible to ensure lining 1 and wearing layer 2 tissue and smooth performance transition, wearing layer 3 and lining Set 1 between have enough bonding strengths.

Decorative pattern 4 is had, for making decorative pattern 4 have preferable wearability and intensity, the width of decorative pattern 4 opening part on the surface of wearing layer 2 The ratio of the depth H of degree L and decorative pattern 4 is between 1.7-1.9.

Embodiment 2: a kind of roll squeezer alloy roller shell as depicted in figs. 1 and 2, including lining 1 and wearing layer 2, lining 1 exists In, outside, have a transition zone 3, lining 1, transition zone 3 and wearing layer 2 in the centre of lining 1 and wearing layer 2 be one whole to wearing layer 2 Body, the organizational structure of transition zone 3 and performance are all located between lining 1 and wearing layer 2.

Wearing layer 2 is the high-alloy steel of special composition, and hardness is high, and thickness is 40-50mm, it is ensured that roller shell has enough wear-resisting Property, prevent again high-abrasive material from using simultaneously and too much cause waste.

Lining 1 uses high-carbon steel, good combination property.

Transition zone 3 is low-alloy steel, is formed by individually cast, and the most first cast wearing layer 2, then pours into a mould transition zone 3, then pour into a mould lining 1, the thickness of transition zone 3 is between 25-40mm.
