Abstract
The invention discloses a high-pressure grinding roller roll surface structure and a manufacturing method. The high-pressure grinding roller roll surface structure comprises a roll sleeve and column nails. Column holes are distributed in the outer surface of the roll sleeve in a staggered manner. The column nails are arranged in the column holes in a clearance fit manner through a bonding agent. The high-pressure grinding roller roll surface structure is characterized in that the column nails are made of non-metal materials. The high-pressure grinding roller roll surface structure has the beneficial effects that due to the fact that the roller sleeve is made of alloy materials, the column nails are made of the non-metal materials, combination of the roll sleeve and the column nails is poor, and the stability of the column nails cannot be improved in a welding manner, the column nails with threaded grooves and the column holes are high in bonding strength under the action of the bonding agent; the column nails are good in wear resistance, so that the running rate of equipment is greatly increased, and the service life of a roll surface is greatly prolonged; and the period requirement for replacing the column nails periodically is fully met, and the production cost of the roll surface is greatly reduced.

High-pressure roller mill is a kind of efficient, energy-conservation milling equipment, is widely used in the industry such as metallurgy, ore production.The vitals of high-pressure roller mill is high-pressure roller mill roller, it is made up of roller shell and roll shaft, in daily production, the high-pressure roller mill of relative rotation is owing to being subject to high-pressure extrusion and the friction of material, roll surface wearing is usually more serious, the production efficiency of impact to voltage roller mill, even reduces the mill efficiency of roller high-pressure roller mill.In order to improve the wearability of roll surface, roll surface is inlaid with stud.
At present, multiple improvement has been had for Roller of High structure, as Chinese invention patent (ZL201210062382.1) discloses a kind of roll surface of roller press, comprise dislocation and be 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; The diameter of No. two little studs is less than the diameter of large stud, and described large stud, a little stud and No. two little studs are that carbide alloy is made.
Chinese invention patent (ZL201110367506.2) discloses a kind of Novel squeeze roller type roller surface structure, comprise roller shell and stud, be interspersed post holes and groove is provided with at the outer surface of roller shell, stud is with matched in clearance form and be arranged in post holes by bonding agent, the upper surface of stud is concordant or lower than the outer surface of roller shell, by heat treatment mode make roller shell outer surface be formed hardened layer that one deck hardness is HRC55-70 in process, the thickness of described hardened layer is 30mm ~ 50mm.
Chinese utility model patent (ZL201220091155.7) discloses a kind of novel stud formula high pressure roller surface structure, adopt stud formula roll surface, the assembling mode of stud is copper brazing, utilize high-quality carburizing steel as roller shell at the roll surface of high pressure roller, simultaneously, roller shell processes slotted eye, the diameter in hole is 10 ~ 30mm, the degree of depth 10 ~ 30mm, axial gap is 15 ~ 50mm, radial clearance is 15 ~ 40mm, is interspersed, and utilizes copper brazing to be welded in the slotted eye of roller shell by hard alloy stud in slotted eye.
Although above-mentioned several surface structure is all provided with hard alloy stud, hard alloy stud weight is large, and expensive, significantly increases production cost.
Summary of the invention
In order to overcome the defect of prior art, the object of the present invention is to provide a kind of Roller of High structure with stud, when changing little, reducing roll surface production cost when in the intensity of roll surface, service life.
A kind of Roller of High structure, comprises roller shell and stud, is provided with at the outer surface of roller shell the post holes that is interspersed, and stud is with matched in clearance form and be arranged in post holes by bonding agent, and be characterized in, described stud is that nonmetallic materials are made.
The present invention improves further, and described nonmetallic materials are ceramic material, can be any one in cermet, aluminium oxide ceramics, zirconia ceramics.
The present invention improves further, and described stud wherein one end is tack, and the other end is ball-crown body, and the cylinder near spherical crown side offers thread groove, screw thread groove depth 0.5-1mm.
The present invention improves further, and described thread groove cross section is any one in rectangle, triangle, trapezoidal or other figures.
Another object of the present invention is to the preparation method that a kind of Roller of High structure is provided, comprise following concrete steps:
(1), make non-metallic material stud, make shaping first on request, the realistic standard of tolerance dimension, tolerance is ± 0.01mm, and offers thread groove in stud;
(2), roller shell holes according to a small amount of Interference Fit Design standard, formed and is covered with whole roll surface and the post holes be interspersed;
(3), in non-metallic material stud smear bonding agent, then fast non-metallic material stud is pressed in the post holes of roll surface by hydraulic means, under adapt circumstance, place 24 ~ 48h.
The present invention improves further, and described adapt circumstance comprises: temperature controls at 20 ~ 30 DEG C, humid control 8 ~ 12%, and under being in ventilation state.
Compared with prior art, advantage of the present invention is:
1), because roller shell is that alloy material is made, stud is that nonmetallic materials are made, both combinations are relatively poor, and the mode of welding cannot be adopted to strengthen the steadiness of stud, and be threaded the stud of groove under the effect of bonding agent, high with the adhesion strength of post holes, and stud wearability is good, substantially increase running rate and the roll surface life-span of equipment, meet the cycle request of periodic replacement stud completely, greatly reduce roll surface production cost;
2), when non-metallic material stud is damaged, when this stud can be heated to more than uniform temperature, bonding agent is made to lose viscosity, what the stud hole due to stud and roll surface adopted is matched in clearance, be easy to be extracted and be replaced with new stud, roller shell then can continue to use, easy to maintenance due to stud, thus extends the life-span of roll surface.
