Description
Technical field
The present invention relates to grinding machinery technical field, relate in particular to a kind of 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, produces ablation by the collision friction between ball mill steel ball, between steel ball and material, 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, and 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, and efficiency is lower, and meanwhile, abrasion-proof steel ball top layer is easy to damage.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of abrasion-proof steel ball, realize the abrasive dust operation in ball mill, it has good grinding efficiency, and has advantages of high abrasion, high rigidity.
A kind of abrasion-proof steel ball that the present invention proposes, comprise steel ball body, described steel ball body is the orbicule that outer surface is made up of multiple regular polygons, described steel ball body comprises table mill layer, strengthening layer and steel matrix composition, table mill layer, strengthening layer, steel matrix form layer structure from outside to inside, described strengthening layer is formed at the lip-deep multilayer system of steel matrix by multiple repetitive coatings, and above-mentioned multilayer system comprises metal level and ceramic layer, and table mill layer is made up of one or more layers infusible compound layer.
In technique scheme, steel ball body is designed to the orbicule that outer surface is made up of multiple regular polygons, make the surface of steel ball body interconnect and form by multiple point, line, surface, make in steel ball working process, changing micro-contact into by the mode of a contact contacts with line, increase the shock surface of steel ball, thereby increased the stress surface of grinding-material, improved grinding efficiency; Adopt the mode of deposited coatings, strengthening layer and table mill layer are set on steel matrix surface, the multilayer system that strengthening layer adopts metal level and ceramic layer stack to form, thereby can provide stronger wearability and hardness by ceramic layer, can provide stronger elasticity and toughness by metal level again, table mill layer adopts infusible compound layer to form, and can promote the wearability of steel ball.
Preferably, described regular polygon is regular hexagon or octagon.
Preferably, in described multilayer system, metal level and ceramic layer are spaced apart.
In above-mentioned technical scheme further, can make metal level and ceramic layer in multilayer system better cooperatively interact, play a role.
Preferably, in described multilayer system, between metal level and ceramic layer, there is the transition zone that the metal-ceramic material that distributed by gradient forms.
In above-mentioned technical scheme further, the transition zone that the metal-ceramic material that employing is distributed by gradient forms, as the transition between metal level and ceramic layer, can promote the binding ability between metal level and ceramic layer.
Preferably, in described infusible compound layer, there are six side's phase crystallites, and above-mentioned six side's phase crystallites are h-(Nb, Zr) N.
In above-mentioned technical scheme further, in infusible compound layer, the existence of six side's phase crystallites can promote the hardness of table mill layer, thereby improves the anti-wear performance of table mill layer.
In the present invention, be optimized by the shape to steel ball and structure, improved the grinding efficiency of abrasion-proof steel ball, and make steel ball there is high abrasion, high rigidity.
