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 the industries such as building materials, metallurgy, mine and chemical industry roll squeezer, high-pressure roller mill.

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 of roller extruding of relatively running.Roller suffered stress in the process that material is pushed 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 thick shape in thin two ends in the middle of forming.In case the wearing and tearing of roller mid portion are larger, roller just need be safeguarded or be scrapped.Therefore, the actual abrasion condition that depends on the roll surface mid portion of the life-span of roller.In the actual motion, normal conditions are that roller often causes reprocessing of whole roller because of the wearing and tearing of mid portion or scraps, and have increased the maintenance cost of roll squeezer, have reduced the operation ratio of equipment.If can guarantee that the roller degrees of wear middle and two ends are basically identical, then this situation will be improved.

Chinese patent CN201120334319.X has announced a kind of roll squeezer hard alloy stud roll surface, comprise roll surface and large stud, described large stud is located on the roll surface, on roll surface, also be provided with little stud, described little stud is around large stud setting, and appearing of little stud highly is lower than the height of appearing of large stud, and described roll surface is made by high strength steel, and described large stud, little stud are made by carbide alloy.

Chinese patent CN2201020587636.8 has announced a kind of roll surface for resurfacing welding of rolling press, and built-up welding has decorative pattern on roll surface, it is characterized in that: this decorative pattern is comprised of two groups of staggered in opposite directions parallel word lines.

Above-mentioned patent purpose is to increase the wearability of roll surface, and roll surface everywhere anti-wear performance is identical, in the situation that the stressed different use procedure middle roller that still can't solve becomes middle thin two pluckings problems.

Summary of the invention

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

The object of the invention realizes by following technical proposals:

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

As optimal way, 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 optimal way, it is consistent that the built-up welding of described built-up welding decorative pattern height and stud are exposed the roll surface height.

As optimal way, 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: can guarantee effectively that roller roll surface in wear process keeps wearing and tearing everywhere synchronously, keep the original geometry of roller with this, be conducive to improve the roll squeezer operation ratio, reduce the roll squeezer maintenance cost.

The specific embodiment

Following non-limiting examples is used for explanation 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 comprises cylindrical metal roll body 1, at roll body 1 roll surface centered by the roll surface center, uniform stud 2 in roll surface overall width 1/3～3/4 scope, the 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.It is consistent that built-up welding height and the stud 2 of built-up welding decorative pattern 3 exposed the roll surface height.As optimal way, built-up welding decorative pattern 3 lines can be any lines, be preferably a word line, tiltedly shape line, netted line or ripple glaze, shown in Fig. 2 to 5.

Produce a kind of roll squeezer motor synchronizing wearing and tearing roller 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 the uniform diameter 16mm of 200mm part, and the remainder roll surface is with the high-abrasive material built-up welding decorative pattern 3 of the netted line of built-up welding equably.In running, because hardness, intensity and the wearability of roll body 1 mid portion stud 2 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 is in the situation that stressedly can keep synchronously wearing and tearing with built-up welding decorative pattern 3 greater than two ends, guarantee the original geometry of roller, thereby improve the roll squeezer operation ratio, reduce the maintenance cost of roller.

The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
