Abstract
The utility model relates to equipment for continuous casting and refining stainless steel, being composed of a coreless induction furnace or a core-type induction bakie (1), a crystallizer (2) for a horizontal continuous casting machine, a bottom blowing argon-oxygen air brick (3), a supporting plate (4), a three-way connection (5), an air supply tube (6), etc. The utility model is characterized in that a conical air brick is arranged at the bottom of the coreless induction furnace. Besides the advantages of an AOD method and LF refined steel liquid, the utility model also has the advantages of simple structure and novel method. The utility model can improve the draw rate of horizontal continuous casting and the quality of casting blanks.
Description
The utility model is a kind of rust steel continuous casting purifier, particularly adopts the device of the flat conticaster continuous casting circle of electric induction furnace refining stainless steel water distribution (side) base, belongs to the metallurgical continuous casting field.
The technological difficulties that adopt induction furnace to smelt the flat conticaster continuous casting circle of the high stainless steel water distribution of nickel chromium content (side) base are: not only viscosity is big owing to contain the high molten steel of chromium, the chromium slag is mobile poor, and very easily by the air secondary oxidation, in addition induction furnace is because the kelvin effect of electric current, liquid steel temperature in the stove is inhomogeneous, causes and easily causes continuous casting to break accident.The rate that pulls into only is about 50%, has seriously restricted the normalization of production and the performance of horizontal casting new and high technology advantage.
The purpose of this utility model is to solve an above-mentioned difficult problem, BOTTOM ARGON BLOWING technology by the structure of using argon oxygen air supply pipe and conical air brick with traditional argon oxygen mix steel making (AOD) law technology and ladle furnace refining method (LF method) is applied in the horizontal casting induction holding furnace, both brought into play the superiority that adopts induction furnace Returning blowing keto technique smelting stainless steel tailing decarburization and cr yield, reclaims chrome-nickel, stir refining liquid steel by Argon again, uniform temperature, what help continuous casting carries out and reduces the strand slag inclusion smoothly, defectives such as middle crack improve lumber recovery;
The purpose of this utility model is to realize like this.It is by coreless induction furnace (or core induction tundish is arranged), the horizontal caster crystallizer, bottom blowing argon-oxygen gas permeable brick, supporting plate, three-way connection and air supply pipe etc. constitute, and it is characterized in that: at coreless induction furnace or there is core induction tundish (1) bottom that a conical bottom blowing argon-oxygen gas permeable brick (3) is installed; A straight hole greater than air brick (3) diameter at butt end 5-10 millimeter is opened in coreless induction furnace or the bottom that has core to respond to tundish (1), bottom blowing argon-oxygen gas permeable brick (3) uses bolted on furnace bottom by supporting plate (4), and argon oxygen air supply pipe (6) is connected on the supporting plate (4) by three-way connection (5) and pipeline.Air brick supplies road argon oxygen gas mixture by threeway argon oxygen supply air line; Thereby reach energy Argon oxygen decarburization and cr yield in fusion process, stir refining liquid steel, uniform temperature, the continuous casting of improving the standard pulls into the purpose of rate and slab quality.
The utility model has the advantages that: simple in structure, method is novel easy to implement, has the advantage of AOD method and LF method refining liquid steel concurrently.Not only be adapted to 0.25-0.5 ton coreless induction furnace, also being adapted to the 10-15 ton has core induction tundish.Not only be adapted to stainless steel continuous casting, also be adapted to the continuous casting of other high temperature alloy.The continuous casting of improving the standard is pulled into rate and slab quality has effect of crucial importance.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model overall structure schematic diagram.
Among the figure 1, coreless induction furnace (or core induction tundish is arranged) 2, horizontal continuous casting crystallizer 3, bottom blowing argon-oxygen gas permeable brick 4, can regulate supporting plate 5, three-way connection 6, argon oxygen air supply pipe
Embodiment:
Make a call to a straight hole in coreless induction furnace 1 (or core induction tundish is arranged) bottom greater than air brick diameter at butt end 5-10 millimeter.Conical air brick 3 is passed through supporting plate 4 usefulness bolted on furnace bottom.The material knotting of furnace bottom with material adopted on air brick top in the time of at the bottom of the brickwork, and the high fire proofed wood knotting of low temperature intensity is adopted in the bottom, during the brickwork lining horizontal caster crystallizer 2 is installed in location knotting on the furnace wall.After furnace lining is accomplished fluently, crystallizer taken off carry out baker, need reinstall crystallizer when adopting the Returning blowing keto technique smelting stainless steel.After treating that steel material fusion temperature reaches the smelting process requirement,, supply with proportional argon oxygen gas mixture by argon oxygen air supply pipe 6 respectively by three-way connection 5, in the hope of reaching decarburization and cr yield, the stir purpose of molten steel temperature and degree of purity of refining.Bring up to more than 95% by original about 50% owing to adopted this device to cause the horizontal casting stainless steel to pull into rate, the slab quality qualification rate is brought up to more than 97% by original 80%.
