Abstract
The utility model relates to an assembled crystallizer, belonging to a device used by a metallurgy continuous casting billet. The assembled crystallizer is composed of a crystallizer, a high-frequency induction coil and an electromagnet. The outer side of a meniscus part of the crystallizer is provided with the high-frequency induction coil. Both sides of a water immersing gap of the crystallizer are provided with a pair of magnetic poles. One side is provided with an N pole, and the other side is provided with an S pole. The assembled crystallizer has the advantages that the surface quality of a casting billet can be improved, and the inherent quality of the casting billet can also be improved.
Description
The utility model belongs to a kind of metallurgy ingot casting equipment, particularly a kind of crystallizer of liquid metal continuous pouring moulding.
In the casting process of metal, in order to improve slab quality, the formation and the growth conditions of submersed nozzle discharge velocity and first scull are very important in the crystallization control device.It on the continuous cast mold mainly is " soft contact technique " and " electromagnetic brake technology " that existing Electro-Magnetic Metallurgy technology is used for." soft contact technique " is by applying high-frequency alternating magnetic field at meniscus surface area, the electromagnetic push that the generation of liquid towards metal is inside, thereby the formation and the growth conditions of the first scull of improvement." electromagnetic brake technology " is by in the submersed nozzle exit constant magnetic field being set, making liquid metal cutting magnetic line in motion process, be subjected to the brake force opposite with the direction of motion, thus control submersed nozzle discharge velocity.These two kinds of Electro-Magnetic Metallurgy technology mainly are respectively applied for and improve slab surface quality and internal soundness, do not reach and both improve surface quality, improve the final purpose of internal soundness again.
The purpose of this utility model is to provide a kind of can improve cc billet surface quality, improves the fourplatemold of strand internal soundness again.
The utility model is realized by following scheme: at crystallizer meniscus place arranged outside radio-frequency induction coil, produce alternating magnetic field after in radio-frequency induction coil, feeding the high frequency alternating current, liquid metal is passed in this magnetic field, thereby in liquid metal, produce induced-current, liquid metal is equivalent to a carrying object, and this carrying object is acted on by again in magnetic field, makes carrying object is produced electromagnetic force, this power is opposite with the static pressure direction of liquid metal, thereby reaches the purpose of soft contact.The place is provided with a pair of magnetic pole at the crystallizer submersed nozzle, one side is that N utmost point opposite side is the S utmost point, and liquid metal is passed in the magnetic field that magnetic pole is produced, and it is perpendicular that direction and liquid metal flow out direction, feed direct current in the coil on the magnetic pole, produce permanent steady electromagnetic field, this magnetic field is by molten metal and vertical with the outflow direction of liquid metal, the liquid metal cutting magnetic line movement, thereby produce electric current therein, and this liquid metal is equivalent to carrying object, and this carrying object is acted on by again in magnetic field, just produce electromagnetic force in carrying object, this power is opposite with the outflow direction of liquid metal; Thereby play braking action.Distance is bigger between two kinds of magnetic fields, thereby influences lessly, can not realize influential simultaneously to two kinds of magnetic field functions separately.
The utility model has the advantages that to have overcome the disadvantage that soft-contact mould and electromagnetic braking crystallizer can only unilaterally improve slab quality, realized to improve slab surface quality, can improve the internal soundness of strand again.
Further narrate content of the present utility model with drawings and Examples below.
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1. magnetic pole; 2. radio-frequency induction coil; 3. submersed nozzle place; 4. meniscus place; 5. crystallizer.
Embodiment: 100 * 100 (mm) continuous small-billet casting fourplatemold.
Top at 100 * 100 (mm) continuous small-billet casting crystallizer, be that liquid metal meniscus district adds 2 circle radio-frequency induction coils around crystallizer, this radio-frequency induction coil is made with the inclined to one side copper pipe of 16mm, feed alternating current to radio-frequency induction coil, the frequency that makes the high-frequency alternating magnetic field of generation is 10000HZ-30000HZ, and apparent energy is 100 kilowatts; Two in the submersed nozzle exit of same crystallizer add an electromagnet respectively, wherein a side is the N utmost point, opposite side is the S utmost point, the constant magnetic field that two blocks of electromagnet are produced is topped whole mouth of a river district, used electromagnet area is the square magnet of 100 * 100 (mm), feed direct current on the coil of these two electromagnet cores, the magnetic field intensity that the strand center is produced reaches 0.01-0.06T.
Claims (1)
1. one kind includes crystallizer at interior fourplatemold, it is characterized in that this fourplatemold adds the high frequency induction coil by crystallizer and electromagnet constitutes, the arranged outside radio-frequency induction coil at crystallizer meniscus place, to the logical high-frequency alternating current of induction coil, the both sides of immersing place, the mouth of a river at crystallizer are provided with a pair of magnetic pole, one side is that N utmost point opposite side is the S utmost point, feeds direct current in the coil on magnetic pole.
