Abstract
The utility model discloses a framework reinforced wearable steel ball which comprises a framework and a metal base body for casting a metal alloy on the framework, wherein the framework is of an integrated structure; the internal space of the steel ball is divided into a plurality of spaces through the framework; the metal base body is filled into the framework and packs the framework. The framework reinforced wearable steel ball disclosed by the utility model is good in collision resistance and surface strength, easy to recycle and high in application efficiency.
Description
Technical field
The utility model relates to grinding machinery technical field, relates in particular to a kind of skeleton and strengthens 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.According to data and practice, show, in the fatigue loss of mill Jie steel ball, the damage on its top layer of steel ball (as small spot corrosion, the damage of burn into surface fatigue and moulding distortion etc.) is in the great majority.And mill Jie steel ball of ball mill adopts solid steel ball mostly, in use, steel ball will be worn, and when may wear to a certain degree, great majority are no longer spherical, but become the different little metallic objects such as flat, depression, be 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 have occupied effective ore grinding space gradually, and the pack completeness of effective milling medium is declined.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of skeleton and strengthen abrasion-proof steel ball, for grinding Jie's steel ball in ball mill conduct, its surface structure is tight, anti-collision performance is excellent, produces fragmentation when wearing and tearing reach setting degree, is easy to reclaim.
A kind of skeleton the utility model proposes strengthens abrasion-proof steel ball, comprise skeleton and by metal alloy being watered to the metallic matrix that casts from described skeleton, described skeleton is integral type structure, described skeleton is divided into a plurality of spaces by described steel ball inner space, it is inner that described metallic matrix is filled in described skeleton, and described skeleton is formed to parcel.
Preferably, described skeleton by some radially bracing piece form, described bracing piece is emitting shape and is arranged in that described steel ball is inner forms described skeleton centered by the described steel ball center of circle.
Preferably, the network structure stephanoporate framework of described skeleton for making through organic precursor dipping ablation.
Preferably, described skeleton is for adopting ceramic powders to make through organic precursor dipping ablation.
Preferably, described metallic matrix casts from described skeleton formation for spheroidal graphite cast-iron is watered.
In the utility model, by skeleton is combined with metallic matrix, with skeleton support metal matrix, and the impact that steel ball surface is subject to can be scattered among whole steel ball, thereby greatly improved 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 is to a certain extent time, substantially do not play ore grinding effect, occupied on the contrary effective ore grinding space, the pack completeness of effective milling medium is declined, the worn steel ball of the utility model structure is to skeleton place, can make steel ball split along skeleton edge broken, thereby be easy to reclaim, discharge, can not affect effective ore grinding space, and, need not abandon this batch of all mill Jie steel ball, improved the service efficiency of steel ball.
Accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram that the skeleton that the utility model proposes strengthens abrasion-proof steel ball;
Fig. 2 is the another kind of example structure schematic diagram that the skeleton that the utility model proposes strengthens abrasion-proof steel ball.
The specific embodiment
As depicted in figs. 1 and 2, Fig. 1 is a kind of example structure schematic diagram that the skeleton that the utility model proposes strengthens abrasion-proof steel ball; Fig. 2 is the another kind of example structure schematic diagram that the skeleton that the utility model proposes strengthens abrasion-proof steel ball.
With reference to Fig. 1, in one embodiment, a kind of skeleton the utility model proposes strengthens abrasion-proof steel ball, comprise skeleton 2 and by spheroidal graphite cast-iron being watered to the metallic matrix 1 that casts from skeleton 2, skeleton 2 is integral type structure, skeleton 2 is divided into a plurality of spaces by steel ball inner space, and metallic matrix 1 is filled in skeleton 2 inside, and skeleton 2 is formed to parcel; Skeleton 2 by some radially bracing piece form, bracing piece is emitting shape and is arranged in that steel ball is inner forms skeleton 2 centered by the steel ball center of circle; After skeleton 2 is made, be placed in mould, the skeleton that can obtain said structure to the nodular cast iron of casting in mould strengthens abrasion-proof steel ball.
With reference to Fig. 2, in another kind of embodiment, a kind of skeleton the utility model proposes strengthens abrasion-proof steel ball, comprise and adopt network structure stephanoporate framework 2 that ceramic powders makes through organic precursor dipping ablation and by spheroidal graphite cast-iron being watered to the metallic matrix 1 that casts from skeleton 2, skeleton 2 is integral type structure, skeleton 2 is divided into a plurality of spaces by steel ball inner space, and metallic matrix 1 is filled in skeleton 2 inside, and skeleton 2 is formed to parcel; After skeleton 2 is made, be placed in mould, the skeleton that can obtain said structure to the nodular cast iron of casting in mould strengthens abrasion-proof steel ball, and wherein, the network structure stephanoporate framework 2 that adopts ceramic powders to make through organic precursor dipping ablation is existing maturation process technology.
In the utility model, by skeleton 2 is combined with metallic matrix 1, with skeleton 2 support metal matrixes 1, and the impact that steel ball surface is subject to can be scattered among whole steel ball, thereby greatly improved 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 is to a certain extent time, substantially do not play ore grinding effect, occupied on the contrary effective ore grinding space, the pack completeness of effective milling medium is declined, the worn steel ball of the utility model structure is to skeleton 2 places, can make steel ball split along skeleton 2 edges broken, thereby be easy to reclaim, discharge, can not affect effective ore grinding space, and, need not abandon this batch of all mill Jie steel ball, improved the service efficiency of steel ball.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
