According to the magnetic-stirring circulating cooling crystallizer, the electromagnetic stirrer and the condenser are adopted for stirring and cooling the molten steel in the crystallizer, the electromagnetic stirrer allows the molten steel in the crystallizer to be uniform and the circulating cooling water allows the cooling speed of the molten steel to be controllable; meanwhile, the cooling water is recyclable after being cooled by the condenser, so that the water resource is saved and the work efficiency of cooling is enhanced.
Description
Technical field
The utility model relates to the cooling tube type mold of a kind of magnetic agitation cycle, belongs to metallurgical crystallizer technical field.
Background technology
Crystallizer is the strand former in continuous casting installation for casting, people claim that it is the heart of conticaster, its function is that the high-temperature molten steel continuously injecting in its chamber is forced cooling by cooling wall, derive its heat, make molten steel in crystallizer, be frozen into gradually required section configuration and certain thickness base shell, and this core is still constantly drawn out from crystallizer end opening for liquid strand, enter secondary cooling zone.For guaranteeing base shell not by bleedout and not producing distortion and defects i.e.cracks, the performance of crystallizer all plays a very important role the production capacity of conticaster and slab quality.
Inner Quality of Billet depends on whether strand inside presents evenly and fine and close equiax crystal solidified structure to a great extent.But the defects such as in the actual process of setting of continuous casting billet, because molten steel cools speed is very fast, the development of column crystal while causing casting blank solidification, often produces " bridgings " phenomenon, brings pipe segregation, loosen, field trash gathering.To this, at casting field, there is adopting the mode of electromagnetic agitation.The operation principle of electromagnetic agitation is based on the law of electromagnetic induction, and current－carrying conductor will be subject to the effect of electromagnetic force and move in magnetic field.Thus, the operation principle of electromagnetic agitation is identical with asynchronous machine, and agitator is equivalent to the stator of motor, and molten steel is equivalent to the rotor of motor.Coil windings by magnetic stirrer produces rotating excitation field, in the molten steel of conduction, produces induced-current, and induced-current and magnetic fields produce electromagnetic force, and molten steel has been played to stirring action.The essence of Stirring During Continuous Casting is by the electromagnetic force of inducting in casting blank liquid core, to strengthen the motion of molten steel.
In addition, in crystallization process, also need to use some cooling modes, conventional is to utilize water cooling.A large amount of water is sprayed onto on crystallizer, to accelerate the process of crystallization.Because time work period is long, production capacity is large, and the required water of using is also more, and this also can cause the waste of water.If can adopt the mode of recirculated cooling water, and add the mode of electromagnetic agitation, can saving water resource, and can make full use of the effect of electromagnetic agitation, contribute to crystallizer crystallization.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in prior art, and provide a kind of reasonable in design, can meet crystallizer cooling needs with stirring in crystallization process, make the controlled crystallization effect of molten steel crystal speed better, reduce the defect that crystallizer crystallization causes.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of magnetic agitation cycle cooler crystallizer, comprise crystallizer copper pipe, cooling jacket, magnetic stirrer and condenser, wherein, cooling jacket is arranged on crystallizer copper pipe outside, magnetic stirrer is arranged on cooling jacket outside, and condenser is arranged on magnetic stirrer outside, is connected with cooling water pipe in cooling jacket, cooling water pipe is connected with condenser, forms recirculating cooling water system.
Further, cooling water pipe is provided with water inlet switch at crystallizer copper pipe top, in crystallizer copper pipe bottom, is provided with effluent switch.
The beneficial effects of the utility model are: this magnetic agitation cycle cooler crystallizer, adopt magnetic stirrer and condenser, for the molten steel in crystallizer, stir with cooling, magnetic stirrer can be so that the molten steel in crystallizer be more even, and recirculated cooling water makes molten steel cools speed controlled,, after cooling water is cooling by condenser, can recycle meanwhile, save water resource, improved cooling operating efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is example structure schematic diagram of the present utility model.
Mark in figure:
1, crystallizer copper pipe; 2, cooling jacket; 3, magnetic stirrer; 4, condenser; 5, water inlet switch; 6, effluent switch.
The specific embodiment
Magnetic agitation cycle cooler crystallizer as shown in Figure 1, comprise crystallizer copper pipe 1, cooling jacket 2, magnetic stirrer 3 and condenser 4, wherein, cooling jacket 2 is arranged on crystallizer copper pipe 1 outside, magnetic stirrer 3 is arranged on cooling jacket 2 outsides, and condenser 4 is arranged on magnetic stirrer outside, in cooling jacket 2, is connected with cooling water pipe, cooling water pipe is connected with condenser 4, forms recirculating cooling water system.Cooling water pipe is provided with water inlet switch 5 at crystallizer copper pipe 1 top, in crystallizer copper pipe 1 bottom, is provided with effluent switch 6.
Using method: crystallizer copper pipe 1 is arranged on conticaster, at the good cooling jacket 2 of its outer setting, connects cooling water pipe, and install magnetic stirrer 3 in cooling jacket 2 outsides, cooling water pipe the other side is tapped in condenser 4.The water inlet switch 5 of opening cooling water pipe supplies water, and closes water inlet switch 5.During work, cooling water constantly circulates in water pipe, cooling to crystallizer copper pipe while arriving crystallizer copper pipe 1 side, cooled water heating, by being cooled after condenser 4, is then sent to again crystallizer copper pipe 1, thereby realize the circulation temperature lowering of cooling water, cooling effect.Meanwhile, open magnetic stirrer 3, utilize the electromagnetism in magnetic stirrer 3 to stir to injecting crystallizer copper pipe 1 molten steel, until after its casting, close magnetic stirrer 3, continue to give cooling.And need to change cooling water time, only need to open effluent switch 6, reopen water inlet switch 5 and can realize and change water.
