Description
Technical field
The present invention relates to a kind of metal smelt technology, relate in particular to a kind of metal electric slag refusion and smelting equipment.
Background technology
Metal electric slag hearth (having another name called electroslag refining furnace) is the resistance heat that produces while utilizing electric current by slag carries out melting a kind of metallurgical equipment as thermal source, its structure mainly comprises that entirety is the crystallizer of stove shape, is positioned at the column of crystallizer one side, column top is provided with horizontal cantilever, on horizontal cantilever, just crystallizer is provided with to the electrode that extends down into crystallizer by terminal clamp.
When electroslag furnace smelting work, electroslag is put into crystallizer, and above crystallizer, form the slag bath for the treatment of melting, adopt terminal clamp to clamp cylindrical electrode, and allow electrode, slag bath, metal bath, steel ingot, end water tank can form current loop by short net wire and transformer. While carrying out electroslag smelting, first this electrode is inserted in slag away from the end of electroslag smelting terminal clamp, subsequently electrode is switched on, in galvanization, electrode and slag bath are emitted Joule heat, by the regulus fusing in slag bath. Motlten metal pools liquid state, through slag bath, falls into crystallizer and forms metal bath, and be subject to water-cooled effect simultaneously, solidifies rapidly formation steel ingot. Before ingot solidification, the metal bath above it and slag bath, play insulation and feeding effect, ensures the compactness of steel ingot. In smelting process, on crystallizer inwall, be formed with the thin skull of one deck, not only make surface of steel ingot bright and clean, also play insulation and heat-blocking action, more heat is conducted to bottom, be conducive to steel ingot crystallographic orientation from bottom to top. Based on above reason, the ingot quality produced by electroslag smelting is good, performance is excellent, and the plasticity under low temperature, room temperature and the high temperature of steel alloy and impact flexibility strengthen, and steel extend service life, therefore electroslag smelting technique is widely used in the industry.
But in existing electroslag smelting technique, the increase of steel oxygen content, the plasticity of steel, toughness drop, another oxide also makes the reduction such as wearability, corrosion resistance of steel. Therefore in esr process, add continuously at regular time and quantity micro-auxiliary material to there is important function as aluminum shot etc. carries out diffusive deoxidation, as it can suppress the oxygen content in metal bath, thereby finally reduce the oxygen content in steel. Can reduce steel ingot pore, loose and segregation generation simultaneously. Add appropriate auxiliary material also can reduce the scaling loss of silicon in steel, the spot segregation of favourable minimizing steel. And effectively make the sulfur content of steel reduce, improve the degree of purity of steel etc. At present, in electroslag smelting process, auxiliary material adds multiplex artificial with the interpolation of iron spoon, operating temperature is high, and dust is many, is harmful to health, and reinforced inhomogeneous, discontinuous or feeding quantity is wayward etc., often cause electroslag smelting product qualified rate low, and special electroslag smelting auxiliary material feeding device is also little, thereby the deoxidation that process aspect is specified etc. can not reach good effect, greatly affect composition and the smelting quality of ESR ingot.
China's number of patent application 201320175064.6 once disclosed a kind of electroslag furnace aluminum shot charger controller, belonged to the reinforced technical field of automatic control of electroslag furnace. Technical scheme is: feed often leaves node strings and is connected on feed vibration electromagnet loop, discharge often leaves node strings and is connected on discharge vibration electromagnet loop, cylinder is often opened node strings and is connected on discharging cylinder loop, and feed often leaves node coil, discharge and often opens the gentle cylinder of node coil and often open node coil and be connected with Programmable Logic Controller respectively.
