Abstract
The present invention relates to an a kind of rotary-type constant voltage of packet mode and prepare the device and method of AMORPHOUS ALLOY RIBBONS, use and jet hole is installed to steel ladle and Ladle Bottom junction, during melting, ladle entirety is reclined and allow jet hole upward.When in ladle, non-crystaline amorphous metal is molten to specific temperature in Frequency Induction Heating, rotate actuating device by machinery and jet hole is rotated to predetermined appropriate location round cooling copper roller curved surfaces, jet hole is by transferring to down upward, and then adscititious gases constant voltage equipment starts automatically.Under the common effect of molten steel hydraulic pressure, air pressure and induction coil, by the non-crystaline amorphous metal molten steel in ladle continuously, constant voltage, the cooling copper roller surface of stable injection to high speed rotating, the AMORPHOUS ALLOY RIBBONS of disposal molding 15 35 μm left and right thickness.The present invention is simple and practical, and technological process is short, easy maintenance, consumption reduction are obvious, production efficiency is high；AMORPHOUS ALLOY RIBBONS thickness can be precisely to ± 0.5 μm, and recovery rate is up to 93%.
Description
Technical field
The invention belongs to the preparing technical field of non-crystaline amorphous metal, be specifically related to an a kind of rotary-type constant voltage of packet mode and prepare non-
The device and method of peritectic alloy band.
Background technology
Non-crystaline amorphous metal melted injection disposal molding prepares metal band, it is not necessary to be repeatedly rolled into through roll squeezer by steel ingot
Type, is metallurgical processing environmental protection, the breakthrough innovation of energy-saving and cost-reducing technique.Injection system carries successful key to protect
Demonstrate,prove the jet hole (mouth of a river) cleaning with spray process before spray complete, it is impossible to because of ladle through jet hole bleed-out at mouth
Middle formation oxidation residua or molten steel high-temperature molten steel in melting process corrodes jet hole.Simultaneously, it is necessary to assure jet hole (water
Mouthful) molten steel constant temperature, constant voltage injection, could spray and prepare high-precision high-quality AMORPHOUS ALLOY RIBBONS.
At present, spray band processed and mainly have two kinds of methods: one is rod type one bag spray method；Two is that many bags (are with two bags
Main) spray method.But both approaches all also exists obvious weakness.
Rod type one bag spray method (as shown in Figure 1), although preferably solve to be protected by intermediate frequency induction heating device
Hold molten steel melting and constant temperature, but jet hole (mouth of a river) cleans complete protection then there is bigger unstability.This
Method, is operated up and down by a high temperature resistant stopper rod, when steel alloy melting with the clogging jet hole of stopper rod, when
Mention stopper rod when need to spray, open mouthpiece.This requires that stopper rod and jet hole seal should be quite accurate, increase processing with
Assembly difficulty, in ladle, alloy is more than 1000 DEG C in fusion process simultaneously, and stopper rod certainly will be by a certain degree of
Melting erosion and high-temperature embrittlement, when need to spray mention stopper rod time, stopper rod because corroding, brittle, add molten steel pressure and viscous
Silk fabric is prone to moment fracture and cannot mention, and sprays unsuccessfully.The method because have stopper rod movable span on steel ladle cover and cannot be close
Envelope, when, in alloy molten steel course of injection in bag, with the decline in molten steel face, jet hole pressure will occur large change, this
Time because of ladle blow-by cannot by input gas pressurized regulate jet hole pressure, the alloy strip one thus prepared
Cause is poor.
Many bags (based on two bags) spray method (as shown in Figure 2), is complete on the basis of rod type one bag spray method
Kind.Though the method preferably solves the cleaning of jet hole and the technical barrier of complete and relative constant voltage spray, but structure is multiple
Miscellaneous, power consumption and molten steel constant temperature aspect existing defects.By two pack band method as a example by, a ladle is exclusively used in alloy melting, claim
For melting bag, another ladle is exclusively used in the injection of molten steel jet hole, referred to as nozzle bag.When beginning alloy melting is unwrapped in melting,
Nozzle bag also needs empty bag to keep, when melting alloy clading molten steel reaches suitable temperature after being heated up to the temperature close with molten steel
Time, from melting bag, pour a certain amount of molten steel (depending on nozzle contains and amasss) into nozzle bag by guiding gutter and funnel,
Again by jet hole moment spray band.When nozzle Baogang liquid level declines, melting bag constantly supplements molten steel more in time, with
Keep basic constant voltage during injection.The method, the structure between ladle and ladle is more complicated with mechanical action, work standard
Standby time length, operating procedure are loaded down with trivial details, and two ladles are both needed to heating and insulation simultaneously, and molten steel heat energy during steel is subcontracted
Scatter and disappear in a large number and consume energy bigger.
Summary of the invention
In order to overcome the deficiency of preceding method, proposition jet hole of the present invention upward, ladle recline rotate mode solve
The cleaning of jet hole and complete (during melting molten steel do not contact with jet hole, not bleed-out)；Solve by the mode of a packet mode
Melting and constant temperature, energy-conservation and simple in construction, easy to operate；Seal with ladle and take gas ftercompction mode to solve spray
Mouthpiece injection constant voltage, it is achieved non-crystaline amorphous metal melted injection disposal molding prepares high-precision metal band.
