Abstract
The utility model relates to a crystallizer for ferroalloy continuous casting, which is composed of a lower flange (1), a fastening screw rod (2), a spring washer (3), a nut (4), an upper flange (5), a copper pipe sealing ring (6) of the crystallizer, a copper pipe (7), a cooling water jacket sealing ring (8) of the crystallizer, and a cooling water jacket (9) of the crystallizer. The utility model is characterized in that the crystallizer uses a lining graphite sleeve pipe (10) which is tightly and integrally combined with the copper pipe (7); corresponding technological parameters are matched, and a produced continuous casting product has the advantages of compact structure, good uniformity, high quality, small cross section of a casting blank which is continuously cast, high cooling speed, small branch crystal spacing and low segregation degree; particularly, chemical components in the length direction of the casing blank is uniform, and a serious phosphorus and sulfur clustering phenomenon caused during die casting is eliminated. The automatic ferroalloy crushing is realized by using methods of a water knife, a mist knife, or gas cooling, etc., large quantity of manpower, material resources and financial resources is saved, and the manpower, the material resources and the financial resources are consumed during tertiary crushing after the die casting; in addition, the loss of partial ferroalloy which becomes powder during tertiary crushing is reduced.
Description
Technical field:
The utility model belongs to the ferroalloy production field, is particularly suitable for the continuous casting of ferroalloy.
Background technology:
Ferroalloy one comprises Si-Fe, Mn-Fe, and Mo-Fe etc. mainly are used as the deoxidier of STEELMAKING PRODUCTION, the adding of alloying element etc.Adopting continuous casing production main difficult point that ferroalloy ran at present is the ferroalloy drawing to be gone out crystallizer, reason be since the fragility of ferroalloy greater than ferrous materials, elevated temperature strength is low, brittle failure easily in the continuous casting process, thereby ferroalloy is difficult to cast continuously shaping.
Summary of the invention:
The utility model purpose is to solve brittle failure easily in the ferroalloy continuous casting process, thereby ferroalloy is difficult to cast continuously the difficult problem of shaping.
A kind of ferroalloy continuous casting crystallizer, constitute by lower flange (1), fastening screw (2), spring washer (3), nut (4), upper flange (5), crystallizer copper pipe sealing ring (6), copper pipe (7), crystallizer cooling jacket sealing ring (8), crystallizer cooling jacket (9), it is characterized in that crystallizer has adopted liner graphite bush (10), sleeve pipe (10) is combined closely with copper pipe (7) and is become one.
Adopt the special crystallizer of liner graphite bushing, graphite cannula produces good lubrication and has slowed down the cooling velocity of crystallizer to ferroalloy to a certain extent between crystallizer and ferroalloy, make ferroalloy have certain high temperature intensity, avoided ferroalloy brittle failure in crystallizer, guaranteed that also the bleedout accident does not take place ferroalloy in the continuous casting process, the dense structure of ferroalloy materials does not produce shrinkage porosite and shrinkage cavity.
According to certain continuous casting process parameter, comprise continuous casting speed, cooling water inflow, ferroalloy fusing pouring temperature etc. in the production, produce the ferroalloy materials of high-quality.
Ferroalloy materials continuous casting process parameter:
Continuous casting speed: 0.5～1.5m/min;
The pressure of cooling water: 0.4～0.6MPa;
The flow of cooling water: 8～40t/h;
The temperature of ferroalloy fusing cast: 1270～1450 ℃.
Description of drawings:
Accompanying drawing 1 is the ferroalloy continuous casting crystallizer of liner graphite bushing.
Lower flange (1), fastening screw (2), spring washer (3), nut (4), upper flange (5), crystallizer copper pipe sealing ring (6), copper pipe (7), crystallizer cooling jacket sealing ring (8), crystallizer cooling jacket (9), liner graphite bush (10).
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
The liquid iron alloy is by the crystallizer graphite cannula that pours into suitable for reading, and ferroalloy cooled and solidified in graphite cannula is a bar, pulls out crystallizer through the crystallizer end opening.
The cooling water of certain pressure and flow is entered by the end opening of crystallizer cooling jacket, through the cooling of the slit between crystallizer water jacket and copper pipe ferroalloy liquid, makes the ferroalloy cooled and solidified become the solid bar, and cooling water is by the outflow suitable for reading of crystallizer cooling jacket then.The ferroalloy continuous casting technological process of production is as follows:
Insulation → employing the tundish that carries out ferroalloy liquid at smelting iron alloy in ore roaster → medium-frequency induction furnace carries out
Iron closes The gold continuous pouring→
Special crystallizerCarry out in (accompanying drawing)
The continuous casting of ferroalloy→ cooling ferroalloy bar →
Automatically BrokenEven-grained ferroalloy materials → weighing → packing warehouse-in.According to this process flow produce composition evenly, dense structure, even-grained ferroalloy materials.
Embodiment: producing diameter with this crystallizer is 60mm ferroalloy bar, the ferroalloy material piece of particle size after cracking 20～60mm.With crystallizer by on the shake table that is fixed on certain vibration frequency shown in Figure 1.The ferroalloy liquid that mine heat furnace smelting is good is poured holding furnace into and is incubated in about 1400 ℃, ferroalloy liquid flows into the insulation bag through the slide gate nozzle of holding furnace, keep under the certain liquid condition, alloy liquid temp slide gate nozzle through tundish in 1270～1350 ℃ scope pours into special crystallizer.The pressure of crystallizer cooling water is 0.3～0.5MPa, and flow is 8～10t/h, and continuous casting speed is 0.5～1.5m/min, and the ferroalloy material piece granularity after the fragmentation is 20～60mm.
