Description
Technical field
This utility model relates to the technical field of metallurgical industry equipment, is specifically related to a kind of Low-cost electric slag hearth high-temperature liquid furnace slag transporter.
Background technology
Along with the fast development of world industry, metallurgical equipment is required more and more higher, to produce the metal material of higher performance by manufacturing.It is suggested from the electroslag metallurgy forties in last century, owing to electroslag metallurgy technology for gold is had a series of superiority, as the superiority (high purity, organize fine and closely woven, any surface finish) of metallicity, economic reasonability (equipment be simple and convenient to operate, producing cost high less than vacuum arc remelting, metal lumber recovery) and technique stable motility can controllability, electroslag metallurgy obtains fast development in countries in the world.It is applied to every field, including Aeronautics and Astronautics, electronics, atomic energy.
Electroslag Process refers to fill melted slag in copper water mold, and consutrode one end is inserted in slag.Consutrode, slag bath, metal bath, steel ingot, bottom water case form loop by short net wire and transformator.In galvanization, slag bath releases Joule heat, is gradually melted consutrode termination, and motlten metal pools drop, through slag bath, falls into crystallizer, forms metal bath, by water-cooled effect, be quickly solidified to form steel ingot.In the electrode tip droplet formation stage, and drop drips the stage through slag bath, and steel-slag is fully contacted, and nonmetallic inclusionsin steel is absorbed by slag.In steel, harmful element (sulfur, lead, antimony, bismuth, stannum) is relatively efficiently removed by steel-slag reaction and high-temperature gasification.Liquid metal, under slag bath covers, substantially avoid and reoxidizes.Because fusing, refine, solidification in copper water mold, this has just stopped the refractory material pollution to steel.Before ingot solidification, there are metal bath and slag bath in its upper end, play insulation and feeding effect, it is ensured that the compactness of steel ingot.The slag bath risen forms one layer of thin skull on crystallizer inwall, not only makes surface of steel ingot bright and clean, also rises and insulate and heat-blocking action, makes more heat to lower conduction, beneficially steel ingot crystallographic orientation from bottom to top.
Electroslag Process can be divided into four-stage as described above: the starting the arc, slag making, remelting, feeding.Two kinds can be divided into again: the first is that the starting the arc, slag making, remelting, feeding four-stage complete entirely in crystallizer according to four-stage；The second starting the arc, slag making complete at other slag making device, treat slag making to complete slag liquid to import in crystallizer to carry out follow-up remelting, feeding.For the first process, owing to the starting the arc and slag making are highly unstable, if the direct starting the arc and slag making easily cause crystallizer damage in crystallizer, reduce the life-span of crystallizer；And use this process to be usually directly to change slag with primary electrode or change primary electrode again with the complete slag of graphite electrodeization and carry out follow-up phase, it is easily caused primary electrode fusing with primary electrode slag, makes bottom ingot casting second-rate；Carrying out follow-up phase again with the complete slag of graphite electrodeization, when changing primary electrode, slag liquid easily crusts.For second process according to injection mode in crystallizer can be divided into upper pouring-in and under pouring-in, in employings, pouring-in slag liquid easily splashes in dross on crystallizer and primary electrode, cause crystallizer and primary electrode damage；Under employing pouring-in for mold structure require height, make with high costs.
