Description
Technical field
The invention belongs to the materials working research fields such as metallurgical, casting, more particularly to a kind of no volume gas nickel-graphite semisolids
The high-efficiency stirring method and device of slurry.
Background technology
In the materials working research fields such as metallurgical, casting, it is often necessary to be stirred to various melts, such as metal half
Solid size, the stirring etc. for adding particle melt, it is therefore an objective to make the homogenization such as temperature, ingredient, the tissue of melt.Stirring efficiency
Stirring intensity is generally depended on, stirring intensity is bigger, and the shearing of formation and turbulent flow are stronger, and melt realizes temperature, ingredient, tissue etc.
The mixing time of homogenization is shorter, and stirring efficiency is higher.However, strong stirring can lead to the volume gas problem of melt, easily
High-temperature fusant oxidation, formation is caused to be mingled with tissue etc., even with protective atmosphere, volume gas can also make to spread stomata in melt,
Material property is caused to deteriorate, it is seen then that volume gas problem has fettered the stirring intensity of melt, reduces stirring efficiency.Nickel-graphite is compound
Material contains the zirconium of 3wt% or so and the graphite particle of 3wt% or so, and the extension ability for having Ni substrate concurrently is strong, plasticity is good, corrosion resistant
Erosion and the greasy property of graphite particle the advantages that well especially high temperature lubrication property is good, arc ablation resistance ability is strong, be to prepare height
The ideal material of warm friction parts, electric contact part, machine components.Due to 3652 DEG C of fusing points 1453 for being higher than nickel of fusing point of graphite
DEG C, thus graphite be in nickel liquid in the form of solid granulates existing for, in addition, due to 8.5~8.9g/cm of density of nickel3
More than 1.9~2.2g/cm of density of graphite3, so, during the routine casting of nickel-graphite melt, graphite particle is easy hair
It is raw to float.If semi solid slurry is made in nickel-graphite melt, the high viscosity of semi solid slurry and nascent solid phase particles have
Effect prevents graphite particle from floating, and still, the high viscosity of semi solid slurry and nascent solid phase particles equally can also hinder graphite particle
Dispersion therefore the equally distributed nickel-graphite semi solid slurry of graphite particle and then obtain high-performance to expeditiously prepare
Nickel-graphite composite material, must just increase the stirring intensity to semi solid slurry, such volume gas problem just more highlights.
The patents of invention such as Authorization Notice No. CN105436436B, Authorization Notice No. CN 103307900B are by " narrowing molten in stir chamber
The methods of body fluid face ", " setting melt disturbance isolator " transmit obstructing agitation to melt liquid level, avoid melt volume gas.This hair
The bright angle completely cut off completely from melt and gas, carries out the creativity and innovation in terms of semi solid slurry stirring, has broken away from volume gas
Constraint to stirring intensity and stirring efficiency can expeditiously prepare the equally distributed nickel-graphite of graphite particle half of no volume gas
Solid size.
Invention content
The technical problem to be solved by the present invention is to volume gas present in the stirring of nickel-graphite semi solid slurry and stirring are imitated
The low problem of rate provides a kind of high-efficiency stirring method and device of no volume gas nickel-graphite semi solid slurry.
The technical solution adopted by the present invention to solve the technical problems is：
The variable volume graphite crucible that prismatic blade is furnished with using inner wall is combined mode to nickel-graphite half with high speed electromagnetic stirring
Solid size is stirred；It is emptied partly solid in graphite crucible using variable volume graphite crucible by reducing the volume of graphite crucible
The all gas on state slurry top, and under conditions of semi solid slurry and ambient atmos completely cut off completely, i.e., no gas source
Under conditions of, the stirring of semi solid slurry is carried out, and then avoid semi solid slurry volume gas from the root cause；It is stirred using high speed electromagnetic
It mixes, in the case where no volume gas fetters, so that nickel-graphite semi solid slurry is generated circumferential high-speed stirred movement, utilize graphite crucible
Prismatic blade on inner wall, constantly by internal nickel-graphite semi solid slurry move on to around, by the nickel-graphite semisolid on top
Slurry moves on to lower part, and then the floating of graphite particle and central segregation is prevented to move, to efficiently obtain the stone of no volume gas
The black equally distributed nickel-graphite semi solid slurry of particle.
The beneficial effects of the invention are as follows：Using the present invention, nickel-graphite semi solid slurry is stirred, can directly be made
For the nickel-graphite semi solid slurry for going out no volume gas, graphite particle is evenly distributed, mixing time can shorten to 2 minutes, stirring efficiency
It improves 310% within 20 seconds 8 minutes than CN102181703A patent disclosure, solves and deposited in the stirring of nickel-graphite semi solid slurry
Volume gas and stirring efficiency low technical problem.
