Background technology
Electroslag remelting is a kind of double refining technology, the integrated metallurgical casting process that the collection steel secondary refining combines with directional solidification.Its principle is that electric current passes through liquid slag scum thermal resistance, and with the metal electrode fusing, molten metal accumulates molten drop, passes slag blanket during drippage and enters metal bath, and crystallization and freezing becomes steel ingot in water mold then.Form the stage at the electrode tip drop, and drop passes the slag bath drippage stage, steel-slag fully contacts, and nonmetallic inclusionsin steel is absorbed by slag.Harmful element in the steel (sulphur, lead, antimony, bismuth, tin) is removed more effectively by steel-slag reaction and high-temperature gasification.Liquid metal has been avoided reoxidizing under slag bath covers basically.Because fusing, refining in the copper water mold, solidify, this has just stopped the pollution of refractory material to steel.Before the ingot solidification, metal bath and slag bath are arranged, play insulation and feeding effect, guarantee the compactness of steel ingot in its upper end.The slag bath that rises forms the thin skull of one deck on the crystallizer inwall, not only make surface of steel ingot bright and clean, also plays insulation and heat-blocking action, and more heat is conducted to the bottom, helps steel ingot crystallographic orientation from bottom to top.Owing to above reason, the quality and the performance of the steel ingot of electroslag remelting production are improved, and plasticity under the low temperature of steel alloy, room temperature and the high temperature and impact flexibility strengthen, and steel prolong service life.
The inner barrel of crystallizer is formed by the copper soil weld.For large-scale crystallizer, the copper coin that is used to make inner barrel is very long.With 240t ingot crystallizer is example: cover copper coin girth 9708mm in the crystallizer, and the moulding of whole volume circle is difficulty very, because copper plate plasticity is better, though have the characteristic of flow harden, but the copper coin of length like this, it is enough to make under the copper coin curved from gravity, thereby the form accuracy after the influence welding.
As the present inventor, be devoted for years to design and manufacturing in crystallizer for electroslag furnace, have rich practice experience, through concentrating on studies of inventor, creatively overcome large-size electroslag furnace crystallizer inner barrel existing above-mentioned technological deficiency when welding by the burst moulding and by corresponding welding procedure equipment.
