Abstract

The invention discloses a roller mill and a self-synchronizing wearing roller of a high-pressure roller mill and relates to roller mill (high-pressure roller mill) rollers. The roller comprises a roller body, column pins are uniformly distributed within a range of 1/3-3/4 of the total roller surface width by taking the right center of the roller surface of the roller body as the center, and patterns are uniformly arranged at other parts of the roller surface in a surfacing way. According to the roller mill and the self-synchronizing wearing roller of the high-pressure roller mill, the original geometrical shape of the roller can be effectively ensured in a wearing process, the running efficiency of the roller mill is improved, and the cost spent on maintaining the roller is reduced.

Description

A kind of roll squeezer and high-pressure roller mill motor synchronizing wearing and tearing roller

Technical field

The present invention relates to a kind of roll squeezer (high-pressure roller mill) roller, be applicable to industry roll squeezer, the high-pressure roller mills such as building materials, metallurgy, mine and chemical industry.

Background technology

Roller of rolling machine is generally cylindrical, forms closed chamber with striker plate, and material is discharged from roll gap after a pair roller compression of running relatively.Roller suffered stress in the process extruded material successively decreases from the middle to both ends gradually, and the wearing and tearing of roller also just reduce from the middle to both ends gradually, thus the shape that in the middle of being formed, thin two ends are thick.Once the wearing and tearing of roller mid portion are comparatively large, roller just need carry out safeguarding or scrapping.Therefore, the life-span of the roller actual abrasion condition depending on roll surface mid portion.In actual motion, normal conditions be roller often because the wearing and tearing of mid portion cause reprocessing of whole roller or scrap, add the maintenance cost of roll squeezer, reduce the operation ratio of equipment.If can ensure that the roller degree of wear that is middle and two ends is basically identical, then this situation will be improved.

Chinese patent CN201120334319.X discloses a kind of roll squeezer hard alloy stud roll surface, comprise roll surface and large stud, described large stud is located on roll surface, roll surface is also provided with little stud, described little stud is arranged around large stud, and the appear height of height lower than large stud of appearing of little stud, described roll surface is made up of high strength steel, and described large stud, little stud are made up of carbide alloy.

Chinese patent CN2201020587636.8 discloses a kind of roll surface for resurfacing welding of rolling press, and on roll surface, heap is welded with decorative pattern, it is characterized in that: this decorative pattern is made up of two groups of staggered in opposite directions parallel word lines.

Above-mentioned patent object is to increase the wearability of roll surface, and roll surface everywhere anti-wear performance is identical, when stressed different still cannot solve use procedure middle roller and become the thick problem in middle thin two.

Summary of the invention

The object of the invention is to: propose a kind of roll squeezer motor synchronizing wearing and tearing roller, effectively can ensure the geometry that roller keeps original in wear process, improve roll squeezer operation ratio, reduce the maintenance cost of roller.

The object of the invention is realized by following technical proposals:

A kind of roll squeezer and high-pressure roller mill motor synchronizing wearing and tearing roller, comprise roll body, at described roll body roll surface centered by roll surface center, uniform stud in roll surface overall width 1/3 ~ 3/4 scope, remainder roll surface is built-up welding decorative pattern equably.

As preferred embodiment, described stud is that carbide alloy is made, and its hardness, intensity and wearability are greater than the high-abrasive material of built-up welding decorative pattern.

As preferred embodiment, it is consistent that the built-up welding of described built-up welding decorative pattern height and stud expose roll surface height.

As preferred embodiment, described built-up welding decorative pattern lines be a word line, tiltedly shape line, netted line or ripple glaze.

Beneficial effect of the present invention: effectively can ensure that roller roll surface in wear process keeps the synchronous of wearing and tearing everywhere, the geometry keeping roller original with this, is conducive to improving roll squeezer operation ratio, reduces roll squeezer maintenance cost.

Detailed description of the invention

Following non-limiting examples is for illustration of the present invention.

embodiment 1:

As shown in Figure 1, a kind of roll squeezer and high-pressure roller mill motor synchronizing wearing and tearing roller, comprise cylindrical metal roll body 1, at roll body 1 roll surface centered by roll surface center, uniform stud 2 in roll surface overall width 1/3 ~ 3/4 scope, remainder roll surface is built-up welding decorative pattern 3 equably.Stud 2 is made for carbide alloy, and its hardness, intensity and wearability are greater than the high-abrasive material of built-up welding decorative pattern 3.To expose roll surface height consistent for the built-up welding height of built-up welding decorative pattern 3 and stud 2.As preferred embodiment, built-up welding decorative pattern 3 lines can be any lines, be preferably a word line, tiltedly shape line, netted line or ripple glaze, as shown in Fig. 2 to 5.

A kind of roll squeezer motor synchronizing wearing and tearing roller is produced by above-mentioned principle, metal roll body 1 diameter 1400mm, roll surface overall width 400mm, roll surface middle width is the circular alloy stud 2 of 200mm part uniform diameter 16mm, the built-up welding decorative pattern 3 of the remainder roll surface high-abrasive material netted line of built-up welding equably.In running, because the hardness of roll body 1 mid portion stud 2, intensity and wearability are greater than the high-abrasive material of adjacent both sides built-up welding decorative pattern 3, so roll body 1 mid portion stud 2 when stressed be greater than two ends can keep synchronous wearing and tearing with built-up welding decorative pattern 3, ensure the geometry that roller is original, thus improve roll squeezer operation ratio, reduce the maintenance cost of roller.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
