Abstract
The invention discloses a wearable steel ball with a reinforced framework. The wearable steel ball comprises the framework and a metal base body formed by casting a metal alloy on the framework, wherein the framework is of an integrated structure and is used for separating a space inside the steel ball into a plurality of spaces, and the metal base body is filled inside the framework and covers the framework. The wearable steel ball with the reinforced framework, disclosed by the invention, has good impact resistance and surface strength, and is easy to recycle and high in use efficiency.
Description
Technical field
The present invention relates to grinding machinery technical field, particularly relate to a kind of skeleton and strengthen 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, and produce ablation by the collision friction between ball mill steel ball, between steel ball and material, be important base parts and components, especially accurate industrial ball plays great function in the national economic development.Show according to data and practice, in the fatigue loss of mill Jie steel ball, the damage (as small spot corrosion, the damage of burn into surface fatigue and plastic deformation etc.) on its top layer of steel ball is in the great majority.And mill Jie steel ball of ball mill adopts solid steel ball mostly, and in use, steel ball will be worn, when may wear to a certain degree, great majority are no longer spherical, but become flat, the different little metallic object such as depression is deposited in ball mill.These little metallic objects do not play ore grinding effect substantially.Along with the accumulation of time, these little metallic objects occupy effective ore grinding space gradually, and the pack completeness of effective milling medium is declined.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of skeleton and strengthening abrasion-proof steel ball, for conduct mill Jie steel ball in ball mill, its surface structure is tight, anti-collision performance is excellent, produces broken when wearing and tearing reach setting degree, is easy to reclaim.
A kind of skeleton that the present invention proposes strengthens abrasion-proof steel ball, comprise skeleton and by metal alloy being watered the metallic matrix casting from described skeleton, described skeleton is integral type structure, described steel ball inner space is divided into multiple space by described skeleton, described metallic matrix is filled in described skeletal internal, and forms parcel to described skeleton.
Preferably, described skeleton is made up of some radial bracing pieces, and described bracing piece is arranged in skeleton described in described steel ball Inner Constitution in emitting shape centered by the described steel ball center of circle.
Preferably, described skeleton adopts high-strength and high ductility steel alloy to make.
Preferably, described skeleton is the network structure stephanoporate framework made through organic precursor dipping ablation.
Preferably, described skeleton is made through organic precursor dipping ablation for adopting ceramic powders.
Preferably, described metallic matrix casts from the formation of described skeleton for being watered by spheroidal graphite cast-iron.
In the present invention, by being combined with metallic matrix by skeleton, with skeletal support metallic matrix, and the impact that steel ball surface is subject to can be scattered among whole steel ball, thus substantially increases the anti-collision performance of steel ball, and can improve the intensity of steel ball surface; After steel ball in use weares and teares, the grinding capacity of steel ball declines, when worn steel ball to a certain extent time, substantially do not play ore grinding effect, occupy effective ore grinding space on the contrary, the pack completeness of effective milling medium is declined, the worn steel ball of structure of the present invention is to skeleton place, steel ball can be made to split along skeleton edges broken, thus be easy to reclaim, discharge, effective ore grinding space can not be affected, further, need not abandon this batch of all mill Jie steel ball, improve the service efficiency of steel ball.

Detailed description of the invention
As depicted in figs. 1 and 2, Fig. 1 is a kind of example structure schematic diagram of the skeleton enhancing abrasion-proof steel ball that the present invention proposes; Fig. 2 is the another kind of example structure schematic diagram of the skeleton enhancing abrasion-proof steel ball that the present invention proposes.
With reference to Fig. 1, in one embodiment, a kind of skeleton that the present invention proposes strengthens abrasion-proof steel ball, comprise the skeleton 2 that adopts high-strength and high ductility steel alloy to make and by spheroidal graphite cast-iron being watered the metallic matrix 1 casting from skeleton 2, skeleton 2 is integral type structure, steel ball inner space is divided into multiple space by skeleton 2, and it is inner that metallic matrix 1 is filled in skeleton 2, and forms parcel to skeleton 2; Skeleton 2 is made up of some radial bracing pieces, and bracing piece is arranged in steel ball Inner Constitution skeleton 2 in emitting shape centered by the steel ball center of circle; After being made by skeleton 2, be placed in mould, the skeleton that nodular cast iron of casting in mould can obtain said structure strengthens abrasion-proof steel ball, and wherein, high-strength and high ductility steel alloy is existing matured product.
With reference to Fig. 2, in another kind of embodiment, a kind of skeleton that the present invention proposes strengthens abrasion-proof steel ball, comprise and adopt ceramic powders through the organic precursor dipping network structure stephanoporate framework 2 made of ablation and by spheroidal graphite cast-iron being watered the metallic matrix 1 casting from skeleton 2, skeleton 2 is integral type structure, steel ball inner space is divided into multiple space by skeleton 2, and it is inner that metallic matrix 1 is filled in skeleton 2, and forms parcel to skeleton 2; After skeleton 2 is made, be placed in mould, the skeleton that nodular cast iron of casting in mould can obtain said structure strengthens abrasion-proof steel ball, wherein, adopts ceramic powders to be existing maturation process technology through the network structure stephanoporate framework 2 that organic precursor dipping ablation is made.
In the present invention, by being combined with metallic matrix 1 by skeleton 2, with skeleton 2 support metal matrix 1, and the impact that steel ball surface is subject to can be scattered among whole steel ball, thus substantially increase the anti-collision performance of steel ball, and the intensity of steel ball surface can be improved; After steel ball in use weares and teares, the grinding capacity of steel ball declines, when worn steel ball to a certain extent time, substantially ore grinding effect is not played, occupy effective ore grinding space on the contrary, the pack completeness of effective milling medium is declined, the worn steel ball of structure of the present invention is to skeleton 2 place, steel ball can be made to split broken along skeleton 2 edge, thus be easy to reclaim, discharge, effective ore grinding space can not be affected, further, need not abandon this batch of all mill Jie steel ball, improve the service efficiency of steel ball.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
