Description
Technical field
Technology the present invention relates to processing for the Conducting copper tile of mineral hot furnace, more particularly to one kind make of aluminothermic process
The centrifuge of steel back fine copper lining electric conducting compound tile.
Background technology
Current mineral hot furnace method is the main method for producing ferroalloy, the main expendable part of mineral hot furnace electrode used therein holder-lead
Electrolytic copper watt is the vital part of the equipment（See Figure of description Fig. 1）, it is raw originally that its service life directly affects production.
Traditional Conductive holding element is formed with H96 brass castings, because its entirety is made with copper, the consumption of copper is big, into
This height, and H96 copper has 4% debris（Mainly deoxidation residue and to improve other elements for adding of casting character）, relative to
Fine copper（T99）Resistance is big, electric conductivity reduction by 20~30%, and further drawback be copper elevated temperature strength it is low, due to workpiece work
Environment temperature is high, and it often fails in being on active service because of ablation, crackle, chip off-falling, and service life is limited.
Traditional Conductive holding element due to entirety is made with copper, makes steel back fine copper lining with aluminothermic process using aluminothermic process
Electric conducting compound tile, therefore, does not see the report that useful aluminothermic process makes the centrifuge of steel back fine copper lining electric conducting compound tile yet.
The content of the invention
It is an object of the invention to provide the centrifuge that steel back fine copper lining electric conducting compound tile is made of aluminothermic process.
The solution of the present invention is such：
Including carrying roller, centrifugal drum, it is characterised in that：The centrifugal drum is provided with least two aluminothermy casees, the aluminium
Back of the body body is set along roller inner arm in hot tank, compound lining, thermite bed material, thermite base are sequentially placed on the surface of back of the body body
Tungsten filament is placed with material, the filling fire resisting material in aluminothermy case, the thermite base-material, the tungsten filament is connected by conductive mechanism
Power supply, energization tungsten filament ignite the back of the body body filling thermit reaction system thermite and under the action of the centrifugal completion fine copper lining system
It is standby.
More specifically technical scheme also includes：The aluminothermy case is provided with exhaust outlet towards centrifugation rotating shaft one end, in centrifugation rolling
There is blast pipe at cylinder middle part, and the blast pipe is connected with the exhaust outlet of aluminothermy case, and the blast pipe connects air.
It is an advantage of the invention that using steel, iron as back of the body body, using the fine copper liquid produced by thermit reaction as lining material,
By the complex of two kinds of material metallurgical bindings under apocarpy, back of the body body material is stainless refractory steel or heat-resisting cast iron, and heat is strong
Degree is high, and heat shock resistance and the burn into of resistance to gas lining material are fine copper, and electric conductivity is strong, and the two assigns work with metallurgical binding complex
The preferable working characteristics of part, and cost is low.

Tracheae 9 is connected with the exhaust outlet of aluminothermy case 6, and the blast pipe 9 connects air, for excluding the gas after igniting.
The present embodiment can once process three pieces of electric conducting compound tiles using three aluminothermy casees.
The operation principle of the present embodiment is：Centrifugal drum 10 is driven to rotate by drive roll 11, energization tungsten filament 7 ignites back of the body body
The thermite base-material 4 and thermite bed material 3 in thermit reaction system are loaded, high temperature, thermite base-material 4 and thermite bottom is produced
Copper material formation liquid and completion fine copper lining preparation under the action of the centrifugal in material 3.Fine copper liner thickness is by loading thermite
Base-material amount is controlled（Generally 15~35mm）, thermite base-material make under aluminothermy and centrifugal action fine copper lining with the back of the body body knot
Metallurgical binding is combined into, the purity of the copper of lining is up to 99.7%, and tissue makes close, pore-free, inclusion defect, electric conductivity height, and heat is strong
Degree is improved, and service life is long.
