Description
Technical field
The present invention relates to high temperature resistant, wear-resisting ground compound material, particularly relate to a kind of new ceramics alloy lining and system thereof
Preparation Method.
Background technology
In modern commercial production, especially in the industrial and mining establishment such as metallurgy, electric power, mine, coal, cement, get more and more
Problem come from production equipment by the raw-material impact such as Ore, slag, friction, high temperature and corrosion large batch of folding
Damaging, in annual commercial production, the secret of success consumes substantial amounts of metal.Thereby, it is possible to ensure the impact resistance of equipment, wearability, high temperature resistant
And corrosion-resistant material is most important.
Nowadays in the various fields such as commercial production, storage transport and chemical industry, all there is numerous evils slightly ring
Border, the combination property for equipment requires the highest, and therefore, the material of single performance can not be satisfied with present industry
The demand produced.Multifrequency nature is combined by compound material, meets Production requirement greatly.In recent years, for compound
The research and development of material also achieve corresponding achievement.If notification number is the Chinese invention patent of CN101898239A, a kind of compound resistance to
Mill material ceramic particle reinforcement preparation method, this reinforcement be sintered in vacuum high-temperature environment by WC ceramic particle and
Become, make required variously-shaped precast body by the mould of design difformity size, precast body is arranged in casting mold
End face, after then using negative pressure casting method casting metals, molten metal penetrates into precast body ceramic particle reinforcement and forms composite wood
Material.In the present invention, its method utilizes calcining to generate ceramics preparative body, then use the method for negative pressure casting metals liquid by metal and
Ceramic Composite, in the method, owing to metal is different with pottery self character, the method for direct pouring is difficult to be metal and ceramic phase
Fusing is an entirety, and in use, first metal can receive abrasion and break and change, and the impact resistance of pottery is poor, because of
This, service life is short, meanwhile, using tungsten carbide as raw material, and the high cost used in tungsten carbide, originally multiple in order to other
The intensity of ceramic material will be affected after conjunction.
Notification number is the middle promulgated by the State Council patent of CN105149875A, it discloses a kind of low cost, high abrasion ceramal again
Close the manufacture method of liner plate, pretreated ceramic particle is mixed homogeneously must mix with low-melting alloy powder binding agent
Thing；Said mixture is filled in molding in mold cavity, and biscuit is put in drying baker together with mould and is dried, in vacuum drying oven
Sinter to obtain ceramic preform；Ceramic preform is fixed on ceramal prefabricated component casting mold mold cavity surface, then pours into a mould resistance to break-in
Gold molten metal, obtains ceramal prefabricated component；Ceramal prefabricated component is carried out heat treatment；Melting base metal material forms gold
Belonging to liquid, then cast enters casting mold die cavity, obtains liner plate base, ceramal prefabricated component is finally welded on liner plate base formation
Composite liner.In the application, directly pottery is sintered after metal mixed, owing to pottery is different with the characteristic of metal, therefore, molten
Metal after change and pottery are less susceptible to fuse together, although composite liner can have corrosion resistance and wear-resisting, but,
Poor for shock resistance.
