Technical field
The invention belongs to the materials working research fields such as metallurgical, casting, more particularly to a kind of no volume gas zinc-carbonization silicon melts
High-efficiency stirring method and device.
Background technology
In the materials working research fields such as metallurgical, casting, it is often necessary to various melts are stirred, such as metal half
Solid size, the stirring for adding particle melt etc., 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.Zinc-silicon carbide is multiple
Condensation material contains the germanium of 16wt% or so and the silicon-carbide particle of 5wt% or so, have concurrently the corrosion resistance of Zinc Matrix, weatherability,
The advantages that compatibility, adhesion be excellent and the hardness of silicon-carbide particle is high, thermal stability is good, wear-resisting, in bearing, bearing shell, mold
And there is wide application in terms of various protectors.Since 2700 DEG C of the fusing point of silicon carbide is higher than 419 DEG C of the fusing points of zinc,
Silicon carbide is existing in the form of solid granulates, in addition, 6.3~7.2g/cm of density due to zinc in zinc liquid3More than carbon
3.0~3.2g/cm of density of SiClx3, so silicon-carbide particle easily floats in zinc-carbonization silicon melt, therefore, to
It expeditiously prepares the equally distributed zinc of silicon-carbide particle-carbonization silicon melt and then obtains high performance zinc-silicon carbide compound material
Material, must just increase the stirring intensity to melt, such volume gas problem just more highlights.Authorization Notice No.
The patents of invention such as CN105436436B, Authorization Notice No. CN 103307900B by " narrow stir chamber in melt liquid level ",
The methods of " setting melt disturbance isolator ", which obstructs agitation, transmits to melt liquid level, avoids melt volume gas.The present invention is from melt
It sets out with the angle that gas completely cuts off completely, carries out the creativity and innovation in terms of melt stirring, broken away from volume gas to stirring intensity and stirred
The constraint of efficiency is mixed, can expeditiously prepare the equally distributed zinc of silicon-carbide particle-carbonization silicon melt of no volume gas.
Invention content
