Abstract
The utility model relates to a cast-iron grinding ball, the interior of which is provided with reinforcing ribs which can be made of steel bars or nodular cast-iron bars; the reinforcing ribs are placed in a mould cavity before casting to form radial shape or mesh shape; the reinforcing ribs can be merged with a body to perform a reinforcing function after the casting to make the grinding ball be uneasily broken, and the service life of the grinding ball is prolonged. The cast-iron grinding ball with reinforcing ribs has the advantages of simple technology, low cost and long service life and can be produced by using general casting technology.
Description
The utility model relates to the metal dust process equipment.
Abrading-ball is the expendable element in the industries such as metallurgy, mine, building materials, electric power, coal, cement.China uses multiple abrading-ball at present.Forged steel abrading-ball toughness is better, but wearability is relatively poor, and service life is short.White cast-iron grinding ball hardness height, but toughness is relatively poor, easily broken in use.Therefore both at home and abroad to how improving the service life of abrading-ball, reducing production costs and having carried out big quantity research.Cast-iron grinding ball is because production cost is low, hardness is high, good casting property, and technology is simple, be easy to be shaped.Therefore obtained aborning to use widely.But when the casting cast-iron grinding ball,,, usually form shrinkage cavity, influence service property (quality) in the abrading-ball centre as inappropriate technology because material shrinks greatly.
The purpose of this utility model is the design cast-iron grinding ball that a kind of anti-wear performance is good, broken rate of grinding ball is low, cost is low.
Formation of the present utility model is that said muscle can be netted, radial, can be linear pattern, shaped form at the inner reinforcement of cast-iron grinding ball.The material of muscle can be identical with spheroid, also can use reinforcing bar, spheroidal graphite cast-iron muscle.
Illustrate that accompanying drawing is as follows:
Fig. 1 is the cast-iron grinding ball profile of not reinforcement.
Fig. 2 is the cast-iron grinding ball profile that adds line of radiation shape muscle.
Fig. 3 is the cast-iron grinding ball profile that adds the radial muscle of curve.
Fig. 4 is the cast-iron grinding ball profile that adds netted muscle.
Accompanying drawings embodiment is as follows:
Fig. 1 is the cast-iron grinding ball of reinforcement not, middlely easily produces shrinkage cavity, lower, the easy fragmentation of intensity.Fig. 2 is the cast-iron grinding ball that adds line of radiation shape muscle.Fig. 3 is the cast-iron grinding ball that adds the radial muscle of curve.Fig. 4 is the cast-iron grinding ball that adds netted muscle.All available metal type or the sand castings of above-mentioned various abrading-ball, during casting with prefabricated reinforcement, be suspended in the die cavity, also can be supported in the die cavity, after molten iron pours into die cavity, reinforcement promptly fuses with molten iron, after solidifying, at an inner skeleton, the reinforcement effect of forming of abrading-ball, the fragmentation of abrading-ball increases the service life in the time of can preventing to use.
Adopt reinforcement abrading-ball of the present utility model, the good characteristics of existing general cast-iron grinding ball wearability are difficult for fragmentation again, long service life, and technology is simple, cost is low.
