4th step, aluminum-boron carbide laminar composite strand continues to move down in the presence of traction apparatuss 14, temperature
Gradually cool down, after the strand obtaining needing size, logical at a temperature of 500 DEG C (temperature is the 0.7-0.8Tm of cladding material)
Cross roll 13 and carry out rolling process；After in the range of aluminum-boron carbide composite material strand pull-out crystallizer 8, water can not be used
Device for cooling, using process parameter control ingot casting temperatures such as the cooling effect of crystallizer 8 and casting speeds, using the high temperature of its own
Directly carry out rolling process；Realize the continuous preparation production of short route, process is simple, energy saving.
Ceramic-metal composite in the present embodiment is the mixture of Al alloy powder and boron carbide ceramics granule, metal
Ceramic composite can choose different granularities, the metal of purity and ceramic powder particle according to different application requirements
It is dried dehydration, mixing, puts into powder in feed preparing device after ball-milling treatment according to certain component ratio；Metal material
The selection of material is with based on aluminium alloy；During traction apparatuss 14 are drop-down to strand, have no direct water cooling device, using crystallization
The process parameter control strand temperature such as the cooling effect of device and casting speed, directly carries out rolling using the high temperature of its own
Reason.
The setting of continuous casting parameter：
The setting of continuous casting parameter can be realized by computer simulation means, and the primary premise realizing parameter calculating is to set up
Mathematical model, calculates the heat transfer between different medium.First the casting process in this patent is reduced to two independent models：
The one-dimensional model of crystallizer interface Temperature Distribution, and the one-dimensional model of complex ingot blank air cooling.
1st, crystallizer interface
The one-dimensional model of crystallizer interface Temperature Distribution, is divided into the 3 interface heat exchanges of 4 parts as shown in Figure 2, point
It is not the heat exchange of molten metal and metal scull, the heat exchange of metal scull and crystallizer wall, the heat of crystallizer wall and cooling water
Exchange.Overheated heat constantly outwards transmits to be molten metal core by hot-fluid exchange, to solidification.
(1) heat transfer of molten metal and scull
Molten metal is represented by with the hot-fluid of green shell：
qe=he(TC-TL) (1)
In formula, qePass to the hot-fluid of green shell for molten metal；heConvection transfer rate for molten metal and green shell；TCFor gold
Belong to liquid pouring temperature；TLFor molten metal liquidus temperature.
Convection transfer rate heCan be calculated by means of the convection heat transfer' heat-transfer by convection formula of forced fluid vertical flat plate：
In formula, heConvection transfer rate for molten metal and green shell；ρ is alloy density；C is alloy thermal capacitance；Before v is solidification
Along molten metal liquid movement speed；η is alloy fluid viscosity；λ is molten metal heat conductivity；L effectively cools down height for water-cooled baffle.
(2) heat transfer within metal scull
Heat transfer in scull is conducted it is assumed that under one-dimensional stable, hot-fluid is represented by for one direction from inside to outside：
In formula, qsIt is the heat flow density by solidified shell；LTFor molten metal liquidus temperature；TiLean on for alloy elder generation solidified shell
Nearly baffle side temperature；ekFor thickness of solidified slab shell in secondary；λ is alloy convection conduct heat coefficient；
(3) heat transfer of solidified shell and crystallizer wall
Solidified shell is more complicated with the diabatic process of water-cooled baffle, need to consider because of metal solidification shrinkage and crystallizer wall it
Between the air gap that produces, heat exchange herein carries out with heat radiation and convection current.
q2i=ε σ0(Ti 4-T2 4)+hi(Ti-T2)=h2i(Ti-T2) (4)
In formula, q2iFor hot-fluid from green shell surface to stainless steel surface；ε is radiation coefficient；σ0For Boltzmann constant；Ti
For alloy elder generation solidified shell near baffle side temperature；T2For corrosion resistant plate hull-skin temperature；hiFor air gap convection transfer rate；h2i
For the coefficient of heat transfer between solidified shell and water-cooled baffle.
(4) crystallizer wall conduction heat transfer
Similar to metal scull it is assumed that under one-dimensional steady statue, its heat flow density can be expressed as：
(5) conduct heat between crystallizer wall and cooling water
Calculated by the hot-fluid that cooling water convective motion is taken away：
qW=hW(T1-TW) (6)
In formula, qwThe hot-fluid taken away for cooling water convective motion；hwHeat convection system for cooling water and stainless steel shoe
Number；T1For corrosion resistant plate internal surface temperature；TwFor cooling water mean temperature.
In all of above formula, interface heat exchange coefficient h is not physics value, but with interracial contact situation, physico
The closely related macroscopical mean parameter of the factor such as condition and interface temperature pressure, can be calculated by measurement temperature.And hot-fluid
Density Q and ingot casting temperature, casting speed, the coefficient such as cooling water intensity is related, therefore can be by computer simulation optimum experiment ginseng
Number.Generally, calculate for simplifying, also Q can be considered as constant.
2nd, complex ingot blank air cooling
It is illustrated in figure 3 the Temperature Distribution one-dimensional model simplification figure under the drop-down rear air-cooled condition of complex ingot blank.This process can
It is reduced to the heat exchange of ceramic material layer and metal level, the heat exchange of metal level and air.
(1) heat transfer of ceramic layer and metal level：
q2i=h2i(Ti-T2) (7)
(2) heat transfer of metal layer itself：
(3) heat transfer to air for the metal level：
The heat of one-dimensional steady-state heat transfer process transmission and heat flow density are all constants, and the thermal resistance of three processes belongs to series connection even
Connect, the heat flow density that thermal resistance is passed through is essentially equal.Therefore：
Can be in the hope of the numerical value of coefficient of heat transfer h.Find when calculating, under the conditions of a lot of air coolings, heat exchange coefficient h value
Greatly, that is, showing to be used herein as air cooling is insufficient to allow ingot casting to be cooled to established temperature it is therefore desirable to stronger cooling effect, using water-cooled
Cooling.
According to result of calculation, for ensure complex ingot blank from crystallizer drop-down after, enter roll, cooling water after 50-100cm
Intensity should be 2-4m3·h-1, casting speed should be 50-120mm/min.
The operation principle of the present invention is：The present invention combines preparation facilitiess and the system of metal-metal ceramic laminar composite material
Preparation Method, the ceramic-metal composite of powder is moved down, through high-frequency induction heating apparatus by hydraulic pressure pusher 2
5 become molten condition (T=Tm), after the scope that the insulating barrier 6 of cavity 4 is located, with the metal bath by crystallizer 8
Contact, is combined with outer layer metal melt in the presence of hydraulic pressure pusher 2, and gradually solidifies real during continuation is drop-down
Existing ceramic-metal composite and the metallurgical binding of metal material, generate metal-metal ceramic laminar composite material strand；Leading
The effect of leading-in device 14 continues to move down, and temperature gradually cools down, after the strand obtaining needing size, in suitable temperature (T=
0.7-0.8Tm) carry out rolling process, cooling effect, water cooling plant and casting speed of crystallizer etc. in downdraw process, can be utilized
Process parameter control ingot casting temperature, directly carries out rolling process using the high temperature of its own；Realize short route, process is simple, section
The continuous preparation of the about energy produces.
Specific case used herein is set forth to the principle of the present invention and embodiment, the saying of above example
Bright it is only intended to help and understands the method for the present invention and its core concept；Simultaneously for one of ordinary skill in the art, foundation
