Description
Technical field
What the present invention relates to is a kind of rafifinal purifier, and particularly a kind of rafifinal single layer crystal solidification purification apparatus belongs to the casting field of metallurgy.
Background technology utilizes segregation method that metal especially aluminium is carried out purifying, gets rid of impurity element wherein, is a kind of sophisticated industrialization process method.As far back as the eighties in last century, countries such as France, the U.S. are all studied the purifying technique of rafifinal, domestic the segregation method purifying technique are also explored.Find that by literature search 1996, Xinjiang Zhonghe Co. Ltd.'s application number was 96204334.6 utility model patent, just related to the device that the aluminium segregation method is purified.This apparatus structure is simple, utilizes the induction heating fusing, leans against the smelting furnace bottom and adds water cooler, has realized the directional freeze of refined aluminium.But this Design of device can not prevent the intrusion of outside impurity element in fusing and process of setting, can not effectively control the mode of crystal growth and the distribution of impurity element.Because whole device is exposed in the air, inhale hydrogen etc. for oxidation oxygen uptake, the air of aluminium liquid, all can not effectively protect, so can only be used for the production that purity is lower than the 4N fine aluminium.Production purity is higher than the rafifinal of 5N, is fully ineligible.
Summary of the invention
The present invention is directed to the deficiency in the background technology, a kind of rafifinal single layer crystal solidification purification apparatus is provided, make it at the characteristics that are easy to grow up in the pure metal process of setting, adopt flat tabular growth pattern, thereby reach the twin crystal three dimensional growth is two-dimensional growth, the interface temperature field becomes simply, and interfacial configuration is easy to control, reaches effective eliminating of solute element.The present invention is achieved by the following technical solutions, the present invention mainly comprises: furnace shell, melting appartus, crystallization apparatus, haulage gear and fixed support, its mode of connection is: melting appartus is arranged at upper furnace, fix by fixed support, crystallization apparatus places the melting appartus below, the catheter of melting appartus is suspended from the top of crystallization apparatus, crystallization apparatus is fixed on the fixed support, link to each other with haulage gear by bolt, haulage gear places outside the furnace shell, cooperates with furnace shell and crystallization apparatus by connecting rod.
Furnace shell is double-deck water-cooled housing, is used to surround the vacuum furnace chamber, is connected to vacuum interface and water coolant interface on the furnace shell.Melting appartus is used to melt solid aluminum to be purified, the fusion crucible, muff and the plunger that are had catheter by Frequency Induction Heating coil, bottom are formed, fusion crucible places coil, is muff between fusion crucible and the coil, and plunger is used to stop up the drain mouth of pipe of fusion crucible bottom.The plunger of the fusion crucible bottom catheter of melting appartus goes out outside the furnace shell by link rob.
Crystallization apparatus is made up of crystallization platform, head end water jacket, high temperature reflector, bottom crystallization water jacket and muff heater, the crystallization platform is flat thin groove shape crucible, the degree of depth is much smaller than long and wide, to guarantee that liquid metallic aluminium is with thin layer drawout in the crystallization platform, the head end water jacket is positioned at crystallization platform one end, closely pastes mutually with crystallization platform sidewall, and bottom crystallization water jacket and muff heater are arranged at crystallization platform bottom, watercooling jacket closely contacts with the crystallization platform, and water coolant passes in and out by interface.Watercooling jacket and muff heater are arranged on the same platform, link to each other with haulage gear by screw thread, link to each other with fixed support by guide rail.Crystallization platform tail end and both sides have thermal insulation layer, and are connected by screw retention with fixed support.The high temperature reflector is made up of three layers of molybdenum sheet, covers crystallization platform top, and the aluminium liquid in the crystallization platform is played insulation.Have the hole of placing catheter on the high temperature reflector.
When the present invention works, at first connect vacuum interface, after vacuum arrives limit, open intermediate frequency power supply, the aluminium ingot in the fusion crucible is melted by coil; After the aluminium ingot fusing, be incubated, open the muff heater power supply of crystallization apparatus simultaneously, connect the water coolant of head end water jacket, bottom crystallization water jacket; Close intermediate frequency power supply, unplug the plunger of fusion crucible bottom catheter, aluminium liquid flow into the crystallization platform along the fusion crucible catheter, starts haulage gear simultaneously, the crystallization watercooling jacket of bottom and muff heater are caudad moved from head end by the connecting rod traction in company with erecting stage, the beginning crystallization; Aluminium liquid on the crystallization platform is by its head end and bottom water cooling system crystallisation by cooling, and crystallization velocity is by the speed control of haulage gear; The thermograde in muff heater control forward position, interface; Crystallization finishes, and closes the power supply of muff heater, opens fire door, takes out the crystal after purifying, and plunger is blocked the crucible bottom drain mouth of pipe again, and crystallization platform crystallization watercooling jacket and muff heater reset, and begin next working cycle.
The present invention has substantive distinguishing features and marked improvement, the present invention is simple in structure, technology is reasonable, simplified the distribution situation in temperature field and solute concentration field in the crystal growing process, improved the controllability of crystal growth interface, and crystalline growth velocity reaches as high as 20cm/h, and production efficiency improves 30% than conventional segregation method, and purification purity can reach 5N5.The aluminium ingot of moulding is tabular, can adopt the milling train cutter to cut off, and has reduced the major diameter aluminium ingot because the pollution that sawing brings.
