Technical field
This utility model relates to field of metallurgical equipment, is specifically related to the graphite electrode that a kind of water-cooled air cooling combines.
Background technology
Ferroalloy (English Ferroalloys), adds as deoxidizer, element additive etc. when the ferroalloy of broad sense refers to steel-making and makes steel possess certain characteristic or reach certain a kind of product required in molten iron.The intermediate alloy that ferrum is elementary composition with one or more, is mainly used in smelting iron and steel；In steel and iron industry general also the intermediate alloy of all steel-making, no matter iron content whether (such as calcium-silicon), referred to as " ferroalloy ", in the most also some simple metal additive and oxide addition being also included within.
Ferroalloy is, by the graphite electrode in electric furnace, the raw material of ferroalloy is produced high temperature so that it is melts and occurs displacement reaction, and then obtain ferroalloy；But finding in actual production, owing to the internal temperature of electric furnace is high, especially at the region Nei Genggao that graphite electrode contacts with raw material, the loss causing graphite electrode is too fast.
" a kind of Water-cooled composite electrode producing mineral wool for direct current furnace " is disclosed at Chinese patent CN201520795740.9, this combination electrode includes the first electrode and the second electrode, described second electrode is arranged on the lower end of the first electrode, the upper end of described second electrode is provided with groove, the lower end of described first electrode is provided with boss, described groove and boss closely cooperate so that the second electrode is connected firmly on the first electrode, and described first electrode interior is provided with cooling water recirculation system；The structure of described cooling water recirculation system is: include water inlet pipe, outlet pipe, intake tunnel and exhalant canal, described intake tunnel is positioned at the first electrode and in tubular construction, vertically and it is coaxially disposed with the first electrode, outside described intake tunnel, the fit inside with the first electrode forms exhalant canal, described water inlet pipe is arranged on intake tunnel upper end, and described outlet pipe is arranged on the upper end of exhalant canal.Although using this combination electrode can reduce the temperature of the first electrode with cooling water recirculation system, it can be difficult to the preferable cooling effect of generation of the second electrode in smelting reality, causing the second electrode in the case of a high temperature, it is lost increase.
Utility model content
This utility model is intended to the graphite electrode providing a kind of water-cooled air cooling to combine, the problem bad to solve cooling of electrode effect of the prior art.
The graphite electrode that a kind of water-cooled air cooling in this programme combines, including electrode body, the top of described electrode body is provided with link slot, the bottom of electrode body is provided with connection boss, on electrode body, matched in clearance has the Conducting copper tile for powering to graphite electrode, the middle part of described electrode body is provided with the insulated water-cooling pipe being wrapped on electrode body, insulated water-cooling pipe includes water inlet end and water side, the water outlet straight tube having axis to parallel is connected with the axis of electrode body on water side, it is provided with the main cavity with electrode body coaxial line inside electrode body simultaneously, the first carbon-coating with some air-vents it is filled with in main cavity.
The operation principle of this programme and beneficial effect thereof: the heat that when can take away electrodes conduct by the insulated water-cooling pipe being wrapped on electrode body, it is outside, reduce the temperature of electrode exterior；And gas is when flowing through the first carbon-coating, and the inside being passed through to ferroalloy fused solution, and the gas flowed is while taking away the heat of electrode interior, and the gas of the inside being passed into ferroalloy fused solution can form numerous air-bubble.Owing to the internal density of bubble is little, cause bubble easily to rise in ferroalloy fused solution, then while ferroalloy fused solution is created mixing effect, also the gaseous impurity in ferroalloy fused solution can be taken out of in the lump, improve the purity of ferroalloy fused solution.Use this electrode, electrode can not only be completed cooling outwardly and inwardly, improve its cooling effectiveness, moreover it is possible to improved the purity of ferroalloy fused solution by the stirring of gas.
Further, described water outlet straight tube is provided with thermometer and with thermometer alarm side by side.Cooling water whether is had to pass through in can detecting insulated water-cooling pipe and water outlet straight tube by thermometer, its Cleaning Principle is: if no-cooling-water passes through, air within insulated water-cooling pipe and water outlet straight tube can be heated to high temperature, when in the pipe that thermometer detects, temperature has exceeded maximum temperature when cooling water passes through, do not cool down water in then can speculating insulated water-cooling pipe and water outlet straight tube or cooling water flow velocity is the slowest, receiving after the information of thermometer at alarm simultaneously, sending chimes of doom to remind staff.
Further, described electrode body is placed with the cavity that some and main cavity communicates, and is filled with inside in a cavity and has the second carbon-coating of some air-vents.By increasing a cavity on electrode body, the gas in main cavity can be shunted to a cavity, the air cooling effect that raising graphite electrode is overall；Simultaneously from a gas of cavity blowout, also the ferroalloy fused solution of graphite electrode periphery can be stirred, to reduce the content of the gaseous impurity within ferroalloy fused solution, improve the purity of ferroalloy.
