Embodiment
Embodiment
Fig. 1 is a kind of Ceramic Composite toothed plate of jaw crusher embodiment toothed plate structure schematic diagram of the utility model, and Fig. 2 is this
A kind of Ceramic Composite toothed plate of jaw crusher embodiment tooth plate schematic cross-section of utility model.As shown in Figure 1 and Figure 2, a kind of ceramics
Compound toothed plate of jaw crusher, including tooth plate body 1 and ceramic block 2, the castingin of ceramic block 2 on the trapezoidal tooth top of tooth plate body 1,
The surface of ceramic block 2 is in same plane with the trapezoidal tooth top surface of tooth plate body 1, is metallurgical between tooth plate body 1 and ceramic block 2
With reference to.Ceramic block 2 is titanium carbide ceramic block, is formed using powder compacting vacuum-sintering, tooth plate body 1 is potassium steel material.Pottery
Porcelain block 2 is that length is that 30~60mm, width are the cuboid that 20~50mm, thickness are 10~25mm, or a diameter of 30~
50mm, length are 10~25mm cylinder.The arrangement of the size of ceramic block 2, the depth of embedded tooth plate body 1 and ceramic block
Depending on density is according to each position abrasion condition of tooth plate body 1, the ceramic block size in the serious two ends in abrading section is larger, embedded
Depth is deep, it is also close to arrange, and the not serious ceramic block size in abrading section is smaller, insert depth shallow one
A bit, arrange more loose, can so reduce the consumption of ceramic material while tooth plate wearability is ensured, reduce cost.
A kind of Ceramic Composite toothed plate of jaw crusher sand mould casting method step described in the utility model is：
Step 1: preparing ceramic block 2.Ceramic block 2 is made of powder compacting, vacuum-sintering, then splits ceramic block 2
30~60mm of growth, wide 20~50mm, high 10~25mm cuboid, or 30~50mm of diameter, 10~25mm of length circle
Cylindricality, and from stainless steel welding stick in the big plane of the length × wide of ceramic block 2 or the upper steel nail of bottom cylindrical face welding, then will pottery
The polishing of porcelain block 2 is cleaned up, and contains the supersaturated borax soln of nickel powder, wherein nickel in the surface smear of ceramic block 2：Borax：Water
Weight ratio is 1:4:5, nickel powder is added in borax can improve the wellability between molten metal and ceramic block, and increase molten metal exists
Mobility on ceramic block, makes that good metallurgical binding face can be formed between tooth plate body 1 and ceramic block 2, it is to avoid slag inclusion and
The formation of stomata.Then ceramic block 2 is dried stand-by.
Step 2: preparing sand mold.Mould is embedded to sandbox, die cavity is made, by the ceramic block 2 after drying by welding thereon
Steel nail penetrate in the molding sand of cavity bottom, play a part of fixed ceramic block 2, prevent that ceramic block 2 is shifted in casting cycle, prick
It is noted that molded die cavity can not be destroyed when entering steel nail, the position that ceramic block 2 is penetrated in sand mold is and tooth plate casting tooth top phase
Corresponding position.High-temperature resistant coating is brushed in die cavity, die cavity is placed in heating furnace dry it is stand-by.
Step 3: casting.According to tooth plate body 1, its specific composition proportion carries out melting, and preceding hot blast of casting is by drying
The die cavity of ceramic block is fixed with afterwards and is heated to more than 350 DEG C, then mould assembly, and melted molten metal is poured into heated die cavity
In, complete casting.The temperature of molten metal casting will be controlled between 1450 DEG C~1550 DEG C.To sand mold Hot-blast Heating before casting
The moisture in die cavity can be excluded, reduces the temperature difference between molten metal and ceramic block 2, reduction molten metal is at the interface of ceramic block 2
Condensation rate, therefore when high temperature metal liquid flow into die cavity after contacted with the ceramic block 2 after heating when, its interface will not be produced
Cold shut defect.Ceramic block 2 absorbs heat from high temperature fluent metal, interface ceramic block 2 is become molten condition, ceramic block 2
The hard particles and bonding phase molecule on top layer are diffused into one another with high-temp liquid metallic molecule, in tooth plate body 1 and ceramics after cooling
Metallurgical bonding layer is formed between block 2, metallurgical bonding layer ensure that the bond strength between tooth plate 1 and ceramic block 2.
Step 4: shake out.After the sandbox after the completion of casting is cooled to below 300 DEG C, shake out knockout is carried out, tooth is obtained
Plate, then cuts off the steel nail on running and feeding system and ceramic block 2, removes the scab on tooth plate surface, and the surface of tooth plate is polished
It is smooth.
Step 5: heat treatment.Put the tooth plate after polishing flat into heating furnace and be heated to 1050~1100 DEG C, insulation 2~3
Hour, then tooth plate is taken out and is quickly put into water, to remain that water temperature is no more than 60 DEG C, treat that tooth plate temperature is reduced to 30 DEG C
When following, tooth plate is taken out from water, quenching is completed.
The Ceramic Composite toothed plate of jaw crusher prepared using above-mentioned Ceramic Composite toothed plate of jaw crusher preparation method, its
Tensile strength Rm >=735MPa, yield strength Re >=440MPa, elongation after fracture A >=15%, contraction percentage of area Z >=15%, punching
