Description
Technical field
The utility model relates to grinding machinery technical field, relates in particular to a kind of high-efficiency abrasion-proof steel ball.
Background technology
Ball mill is one of widely used Super-fine grinder machinery in industrial production.Ball mill steel ball is ball mill equipment grinding material medium, by the collision friction between ball mill steel ball, between steel ball and material, produces ablation, is important base parts and components, and especially accurate industrial ball plays great function in the national economic development.The usage quantity of abrasion-proof steel ball on market is very huge, the abrasion-proof steel ball using in prior art is generally spherical steel ball, in motion process, can only clash into and grind in the mode of a contact, efficiency is lower, simultaneously, in process of lapping, the temperature and the violent friction that due to collision, produce make abrasion-proof steel ball top layer be easy to damage, shorten the service life of abrasion-proof steel ball.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of high-efficiency abrasion-proof steel ball, realized the abrasive dust operation in ball mill, its grinding efficiency is high, long service life.
A kind of high-efficiency abrasion-proof steel ball the utility model proposes, comprise steel ball body, described steel ball body is that spheroid and its ellipticity are less than 0.05, the top layer of described steel ball body is provided with two projections and two projections all around described steel ball body, article one, protrusions parallel is in the major axis of described steel ball body and another protrusions parallel in the minor axis of described steel ball body, from projection intersection to away from projection intersection, twice projection mean breadth all increases gradually, and the top of twice projection is waveform; Described steel ball body comprises wear-resistant coating and steel matrix, and wear-resistant coating and steel matrix form layer structure from outside to inside, and described wear-resistant coating is comprised of multilayer TiN layer and TiCN layer, and TiN layer and TiCN layer are alternately distributed.
In technique scheme, steel ball body is designed to spheroid, meanwhile, at this surface layer of steel ball, is provided with projection, make in steel ball working process, by the mode of a contact, change micro-contact into and contact with line, increased the shock surface of steel ball, thereby increased the stress surface of material, simultaneously, can also increase the pressure in steel-ball collision process, thereby improve grinding efficiency, be that waveform can further promote grinding efficiency by the tip designs of projection; The design of wear-resistant coating can improve the impact resistance of steel ball in collision process, and can promote the abrasive resistance of steel ball, thereby in the service life of improving steel ball, meanwhile, TiN layer and TiCN layer are alternately distributed can be so that the impact resistance of steel ball and abrasive resistance be outstanding.
Preferably, described wear-resistant coating is TiN layer near described steel matrix with away from described steel matrix place.
Preferably, the thickness of described wear-resistant coating is 50-60 μ m.
Preferably, the ellipticity of described steel ball body is 0.02-0.04.
Preferably, the thickness of TiN layer and TiCN layer is 3-5 μ m.
In the utility model, by the shape of steel ball and structure are optimized, improved the grinding efficiency of steel ball, and made steel ball there is in the course of the work longer service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-efficiency abrasion-proof steel ball that the utility model proposes;
Fig. 2 is the schematic cross-section of Fig. 1.
The specific embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of high-efficiency abrasion-proof steel ball that the utility model proposes; Fig. 2 is the schematic cross-section of Fig. 1.
With reference to Fig. 1-2, in a kind of specific embodiment the utility model proposes, a kind of high-efficiency abrasion-proof steel ball, comprise steel ball body 1, steel ball body 1 is spheroid and its ellipticity position 0.03, the top layer of steel ball body 1 is provided with two projections 2 and two projections 2 all around steel ball body 1, article one, projection 2 is parallel to the major axis of steel ball body 1 and the minor axis that another projection 2 is parallel to steel ball body 1, from projection 2 intersections to away from projection 2 intersections, twice projection 2 mean breadths all increase gradually, and the top of twice projection 2 is waveform; Steel ball body 1 comprises wear-resistant coating 5 and steel matrix 6, wear-resistant coating 5 and steel matrix 6 form layer structure from outside to inside, the thickness of wear-resistant coating 5 is 52 μ m, wear-resistant coating 5 is comprised of multilayer TiN layer 3 and TiCN layer 4, the thickness of TiN layer 3 and TiCN layer 4 is 4 μ m, and TiN layer 3 and TiCN layer 4 are alternately distributed, wear-resistant coating 5 is TiN layer 3 near steel matrix 6 with away from steel matrix 6 places.
In the present embodiment, steel ball body 1 is designed to spheroid, meanwhile, on steel ball body 1 top layer, is provided with projection, make in steel ball working process, by the mode of a contact, change micro-contact into and contact with line, increased the shock surface of steel ball, thereby increased the stress surface of material, simultaneously, can also increase the pressure in steel-ball collision process, thereby improve grinding efficiency, be that waveform can further promote grinding efficiency by the tip designs of projection; The design of wear-resistant coating 5 can improve the impact resistance of steel ball in collision process, and can promote the abrasive resistance of steel ball, thereby in the service life of improving steel ball, meanwhile, TiN layer 3 and TiCN layer 4 are alternately distributed can be so that the impact resistance of steel ball and abrasive resistance be outstanding.
