Description
Technical field
The present invention relates to cement manufacture field, particularly relate to Ceramic Balls and the preparation thereof of a kind of built-in alpha+beta titanium alloys skeleton
Method.
Background technology
Cement ball mill have to material strong adaptability, can produce continuously, broken than big, be prone to the thin of speed governing ground prod
The features such as degree.The operation principle of conventional cement ball mill is that material is entered through pan feeding quill shaft spiral equably by feed arrangement
Entering in grinding machine storehouse, have ladder lining board or corrugated liner, the steel ball of built-in different size or Ceramic Balls in this storehouse, barrel body rotation produces
Centrifugal force falls after taking steel ball or Ceramic Balls to certain altitude, and material is produced bang and abrasive action.Cement ball mill is made pottery
Porcelain ball is the conventional grinding material medium of cement ball-milling machine equipment, by touching between cement ball mill Ceramic Balls, material, liner plate
Hit friction and produce ablation, thus the particle diameter of material is reduced further.Therefore, Ceramic Balls hardness in use and wear-resisting
Property be impact one of principal element of grinding shaping effect, simultaneously as ceaselessly clashed into for a long time, mill ball is resisted
Impact property has high requirement.
In prior art, cement ball mill Ceramic Balls has had more employing, great majority to use traditional Al2O3-
CaO-MgO-SiO2 quaternary system, also has a small amount of inventor to improve on its formula, to reach special effect.Such as this
A person of good sense has applied for the many parts of Ceramic Balls using new formulation before this, has high rigidity, high temperature resistant, high life, easy-formation, toughness
Well, the effect of the cement high purity produced.
But, in the research of long-term cement ball mill Ceramic Balls, the inventors discovered that, startup, jerk, throwing pendant etc.
Impact cause broken be one of Ceramic Balls modal damage mode, this greatly govern cement ball-milling industry send out
Exhibition.
Titanium is a kind of important structural metal grown up the 1950's, and titanium alloy is because having intensity, plasticity, tough
Property the feature such as high, corrosion resistance good, thermostability, high formability and be widely used in every field, particularly its specific strength superelevation
Advantage is preced with exhausted all metals and alloy.Wherein alpha+beta titanium alloys is two-phase alloys, has good combination property, structure stability
Good, there is good toughness, plasticity and Hot Deformation Performance, unlike pure titanium and alpha titanium alloy, alpha+beta titanium alloys can also pass through
Heat treatment makes alloy strengthening, and the intensity after heat treatment about improves 50%～100% than annealed condition；Elevated temperature strength is high, can be at 400 DEG C
～long-term work at a temperature of 500 DEG C.Utilize the toughness of the refractory metals such as alpha+beta titanium alloys, plasticity, intensity advantages of higher, adopt
By the method implanting alpha+beta titanium alloys skeleton, the globality that can make Ceramic Balls is more preferable, and can be by skeleton when being impacted
Impulsive force is shared, the most broken.
It is implanted into alpha+beta titanium alloys skeleton in Ceramic Balls and belongs to blank field before this, there is no and see that any research is seen in paper
