Description
Technical field
The utility model is related to technical field of metallurgical equipment, more particularly to it is a kind of be convenient for changing cold piece of bottom stripping formula bottom it is cold
Device.
Background technology
With the fast development of world industry, manufacturing is higher and higher to metallurgical equipment requirement, to produce higher
The metal material of energy.It is suggested from the electroslag metallurgy forties in last century, since electroslag metallurgy technology for gold is by with a series of excellent
More property, (equipment is simple, grasps for superiority (high purity, organize fine and closely woven, any surface finish), economic reasonability such as metallicity
It is high less than vacuum arc remelting, metal lumber recovery to make convenient, producing cost) and technique stabilization flexibility can controllability, electricity
Slag metallurgy is grown rapidly in countries in the world.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 into slag.
Consutrode, slag bath, metal bath, steel ingot, bottom water tank are formed into a loop by short net conducting 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 steel-slag comes into full contact with, and nonmetallic inclusionsin steel is absorbed by clinker.Harmful element in steel (sulphur, lead,
Antimony, bismuth, tin) relatively efficiently removed by steel-slag reaction and high-temperature gasification.Liquid metal is substantially kept away under slag bath covering
Exempt to reoxidize.Because being to melt, refine in copper water mold, solidifying, this has just prevented refractory material to steel
Pollution.Before ingot solidification, there are metal bath and slag bath in its upper end, play insulation and feeding, ensure the compactness of steel ingot.
The slag bath of rising forms one layer of thin skull on crystallizer inner wall, not only makes surface of steel ingot bright and clean, also plays insulation and heat-blocking action,
More heats are made to be conducive to the crystallographic orientation of steel ingot from bottom to top to lower conduction.
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.Stripping formula electroslag furnace bottom at present
It is cold to be divided into two kinds：One kind is Non-water-cooled but later stage dismounting is difficult, and another kind is that have water cooling but bottom water tank is easily breakdown.
