Description
Technical field
The utility model belongs to and affinage metallurgy technical field, and particularly, the utility model relates to a kind of ultrasonic wave metallurgical plant for RH refining furnace.
Background technology
RH refining full name is RH vacuum circulation degassing purifying method.In nineteen fifty-nine by fritz's utility model, wherein RH is that Germany adopted the first letter of the Liang Ge producer of RH refining techniques at that time.Vacuum technique starts application and originates in nineteen fifty-two in steel-making, people often occurred emitting slag phenomenon when producing the silicon steel of silicon content about 2% in casting process at that time, through various test, finally the hydrogen in discovery molten steel and nitrogen produce to emit slag to cause cannot pouring into a mould or producing after rolling the major cause of waste product, various SECONDARY REFINING IN A VACUUM CHAMBER starts to occur thereupon, as vacuum-casting method, ladle drip degassing method, ladle degassing method etc., thus started plant-scale molten steel vacuum processing method, the particularly appearance of vapor jet pump, accelerate the development of vacuum steel-smelting technology especially.
Along with exploitation and the development of vacuum steel-smelting technology, final RH and VD is because the treatment time is short, cost is low, can process the advantages such as molten steel in a large number and become the main flow of vacuum steel-smelting technology, start the appearance along with sequence casting workshop the seventies, RH is because adopt molten steel in the technology of vacuum tank circulation thus reach the treatment time is short, efficiency is high, can mate with revolving furnace continuous casting advantage and adopted in a large number by converter procedure.RH from occur till now over more than 40 year, constantly there is technology upgrading and improvement, thus accelerate the development of RH refining techniques
RH system device is a kind of steel secondary refining tooling for the production of high-quality steel.Whole molten steel metallurgical reaction has in the vacuum tank of refractory lining at block to carry out.The bottom of vacuum tank is the soaking tub of two band refractory linings, and hot-bending pipe is equipped with on top.Pumped gas is discharged to outside factory building to vacuum pump system through gas cooler by hot-bending pipe.
Before steel treatment, first soaking tub is immersed in pending ladle molten steel.When vacuum tank vacuumizes, the barometric point of molten steel surface forces molten steel to flow in vacuum tank from soaking tub (can make molten steel rising 1.48m height in vacuum tank) during about 0.67mbar.Two soaking tubs be communicated with vacuum tank, one is upcast, and one is downtake.Because upcast is constantly blown into argon gas to molten steel, relatively do not have the downtake of Argon to create a higher static pressure difference, make molten steel enter from upcast and flow to downtake by vacuum tank bottom, so constantly circulation repeatedly.Under vacuum conditions, flow through the gases such as the argon gas in vacuum tank molten steel, hydrogen, carbon monoxide to be pumped in molten steel working cycle.Meanwhile, the molten steel entered in vacuum tank also carries out a series of metallurgical reaction, such as reaction between carbon and oxygen etc.; Circulating degasification refining like this makes molten steel be purified.
Molten steel advantage through RH process is obvious, but due to problem that is degassed and inclusion removal, still cannot meet the requirement of some high quality steel, therefore needs a kind of RH a refining unit that can improve Cleanliness of Molten Steel, effectively removal of inclusions further badly.
Utility model content
The purpose of this utility model is, provides a kind of ultrasonic wave metallurgical plant for RH refining furnace, and this device can improve RH refining furnace molten steel cycle efficiency, improve degassed, remove the effect that is mingled with.
For achieving the above object, the utility model have employed following technical scheme:
A kind of ultrasonic wave metallurgical plant for RH refining furnace, described device comprises the outside framework 2 be connected with RH refining furnace upcast 1, establish in described outside framework 2 ultrasonic generator 6 and for ultrasonic generator 6 is produced ultrasonic wave input upcast 1 in ultrasonic wave working head 7; The Argon pipe 4 be connected with upcast 1 is also provided with and around the some argon tube sealings 5 of Argon pipe 4 for hermetic seal in described outside framework 2; Described Argon pipe 4 is connected with argon gas source through outside framework 2 with some argon tube sealings 5.
Preferably, described Argon pipe 4 stretches into one end of upcast 1 is seedpod of the lotus head.
Preferably, described argon tube sealing 5 outside surface arranges some ring through hole 3 in circle shape.Further preferably, described argon tube sealing 5 outside surface arranges eight ring through hole 3 in circle shape.
Preferably, described ultrasonic generator 6 is arranged around some argon tube sealings 5.
Preferably, described ultrasonic wave working head 7 is coated on Argon pipe 4.
Preferably, the number of described argon tube sealing 5 is six.
In the utility model, the power supply supply of Argon pipe, argon tube sealing and ultrasonic generator can integratedly be arranged on outside framework outer side wall.
Ultrasonic wave metallurgical plant of the present utility model can be installed on the Argon position of existing RH refining furnace, and other correct positions also can be selected to install.
In the utility model, ultrasonic generator is arranged around argon tube sealing, while argon tube sealing carries out hermetic seal, can cool to ultrasonic generator again, can better operation.
The utility model adopts ultrasonication, the argon gas bubbles that occurs in metallurgical process can be made broken by its acoustic streaming effect and cavitation effect, so improve RH refining furnace molten steel cycle efficiency and degassed, remove and be mingled with effect.
