Description
Technical field
It the utility model is related to technical field of metallurgy industry, more particularly to a kind of stripping formula electroslag furnace bottom coohng device.
Background technology
With the fast development of world industry, stability requirement more and more higher of the manufacturing to metal material.From previous generation
The electroslag metallurgy forties of recording is suggested, excellent such as metallicity because electroslag metallurgy technology for gold is by with a series of superiority
The opposite sex (high purity, organizing fine and closely woven, any surface finish), (equipment is simple and convenient to operate economic reasonability, producing cost is less than
Vacuum arc remelting, metal lumber recovery are high) and technique stable flexibility can controllability, electroslag metallurgy obtains in countries in the world
Fast development.It is applied to every field, including Aeronautics and Astronautics, electronics, atomic energy.
Electroslag Process refers to the clinker that melting is filled in copper water mold, and consutrode one end is inserted in slag.
Consutrode, slag bath, metal bath, steel ingot, bottom water tank form loop by short net wire and transformer.In galvanization,
Slag bath releases Joule heat, and consutrode termination is gradually melted, and molten metal pools drop, through slag bath, falls into crystallizer,
Metal bath is formed, is acted on by water cooling, is quickly solidified to form steel ingot.Passed through in electrode tip droplet formation stage, and drop
Slag bath drips the stage, and slag is fully contacted, and nonmetallic inclusionsin steel is absorbed by clinker.Harmful element in steel (sulphur, lead, antimony,
Bismuth, tin) relatively efficiently removed by slag-metal reaction and high-temperature gasification.Liquid metal substantially avoid under slag bath covering
Reoxidize.Because being to melt, refine in copper water mold, solidifying, this has just prevented pollution of the refractory material to steel.
Before ingot solidification, there are metal bath and slag bath in its upper end, play insulation and feeding, ensure the compactness of steel ingot.Rise
Slag bath one layer of thin skull is formed on crystallizer inwall, not only make surface of steel ingot bright and clean, also rise insulation and heat-blocking action, make more
More heats is advantageous to the crystallographic orientation of steel ingot from bottom to top to lower conduction.The electric power system of electroslag equipment is steel ingot remelting
Energy source, quality (degree of purity, the fine and closely woven property of tissue and uniformity, any surface finish journey of the stabilization of function system to ESR ingot
Degree) play conclusive effect.
Stripping electroslag is a kind of important electroslag method, and stripping electroslag, which is invented, to be solved ESR ingot length and be crystallized device height
The restricted problem of degree, longer ESR ingot can be produced using stripping, adapt to various industrial needs.The smelting of stripping formula crystallizer
Mode determines that bottom coohng is insufficient, at present in industry way be pull bar front end integrate low flush tank, but with stripping away from
From elongated, cooling effect is deteriorated, and is unfavorable for the longitudinal growth of crystallizer direction and can make poor surface quality.
