Description
Technical field
The present invention relates to a kind of method that high resistance to compression aluminum oxide milling media is prepared in rolling molding, belong to technical field of ceramic material.
Background technology
Aluminum oxide milling media be in process of lapping due to directly impact between material, and aluminium oxide ballstone from impact lack buffering rank
Section and ultimately result in broken ball, fall slag, ftracture, the symptom such as deformation.Above-mentioned various defect problem will cause the grinding efficiency can be increasingly
Low, largely decrease the service life of aluminium oxide ballstone, the impurity simultaneously dropped in a large number causes and is ground material destructiveness
Pollute.When the comprcssive strength of alumina balls is low, the problems referred to above are especially prominent.
The mill ball of isostatic pressing has the comprcssive strength more much higher than the mill ball of rolling molding.Grinding such as diameter 30mm
Ball, the resistance to compression that isostatic pressed is made is more than 280KN, rolling molding then less than 50KN.But isostatic pressing process is complicated,
Equipment investment is high, especially for the dry grinding ball of diameter 13mm～30mm, and its large-scale production critical constraints, efficiency is low,
Product cost is high.And limited by the tradition mill ball comprcssive strength prepared of rolling molding mode, also cannot apply in dry grinding field.
After deliberation, the main cause causing rolling ball comprcssive strength low be rolling ball during rolling, hollow pelletizing rounded grain is broken
Broken, refinement, semi-finished product density is high, and after burning till, goods are the finest and close, and the micro-crack source burning till cooling procedure generation generally exists,
After stress, crackle easily extends, and shock resistance is deteriorated, intensity is low, is also easy to occur that wind crystalline substance bursts and the problem such as foaming.
Summary of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art, it is provided that high resistance to compression aluminum oxide milling media is prepared in a kind of rolling molding
Method, is particularly suited for preparing the dry grinding ball of 13mm～30mm that dry grinding field uses.The method is by using not
With the mode that the pelletizing of characteristic is compounding, it is thus achieved that with ball base as isostatic pressing phase so that it is in containing certain pore, subtract
The crackle that when burning till cooling less, thermal shock produces, and play the effect of activeness and quietness.
To achieve these goals, the present invention includes A, B, C pelletizing three part for compounding rolling ball powder.
A pelletizing is to be spray-dried to directly obtain conventional alumina pelletizing, and pelletizing hardness is low, and this pelletizing is by powder beater powder
Broken destruction forms powder, is also the key component of whole rolling ball.
C pelletizing is to be spray-dried to directly obtain superhard aluminium oxide pelletizing, and case hardness is big, and inner hollow, it is in rolling
Journey is unlikely to be broken, thus introducing portion pore in rolling ball base, can the hardening of this part surface modification simultaneously high hard
Degree pelletizing forms chock effect during ball-billet shape becomes, and as shown in Figure 2, thus reduces the layering of rolling ball base.
The ultra-fine dust collection powder (being also false granule) collected from dust-precipitator when B pelletizing is to prepare conventional pelletizing A, this pelletizing
Constantly grow up during avoiding ball base rolling, can effectively carry out cushioning effect, prevent superhard pelletizing C to be destroyed.
High rigidity pelletizing is by adding a large amount of PVA (polyvinyl alcohol), and improves what spray drying temperature realized.Generally use
It is not added with in the pelletizing slurry of rolling molding or adds the PVA less than 0.3%.For obtaining high rigidity pelletizing, we add now
1.2～the PVA (aqueous solution of the previously prepared one-tenth of this part PVA 10%) of 2.5%, the duricrust produced after utilizing polymeric hardener carries
High pelletizing case hardness, improves resistant to breakage ability when it is knocked.On the other hand, spray drying temperature is also crucial, temperature
Du Taigao Organic substance decomposes rotten, and temperature is the lowest, and PVA component is dried not, and the degree of polymerization does not reaches, pelletizing hardness is inadequate.

Through spray drying tower heat setting formation high rigidity pelletizing granule after weight northylen alcohol, make doping material pelletizing in use
Cannot all be crushed by the collision of semi-finished product ballstone, finally member-retaining portion pelletizing pattern in semi-finished product, particularly retains it
Hollow-core construction, in order to for introducing a small amount of pore in semi-finished product.2, during rolling hardening doping material pelletizing semi-finished product by
Step, successively growth process effectively form chock effect, can effectively prevent the semi-finished product of rolling to be layered, reach semi-finished product
The effect strengthened.
Described polyvinyl alcohol model is 1799, uses vapours directly to melt, ability of at high temperature pelletizing after joining 10% aqueous solution
Reach the case-hardened purpose of pelletizing.The mode that conventional employing agitating heating is melted is unable to reach the hardening strength of pelletizing.
