Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of barostat.
The specific embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 1 to 2, horizontal casting pipe founding processing unit (plant) improves structure, the crystallizer 2 and the pipe formation die tool 3 that comprise continuous casting mouth 11 places that are located at smelting furnace 1, pipe formation die tool comprise graphite-pipe 31 that is located in the crystallizer and the graphite core 32 that is located in the graphite-pipe; Be provided with the draw-gear 4 of traction pipe 8 in the place ahead of crystallizer, be provided with the non-oxidizing outer surface protective device of protection tube blank outer surface, in pipe, be provided with the non-oxidizing inner surface protective device of protection internal surface of bloom at the crystallizer front end.
Described outer surface protective device comprises the airtight protective cover that is connected 5 of the rear end and the front end of crystallizer; the front end of protective cover is a blind end 51; blind end is provided with the through hole 52 that cooperates with pipe; blind end is provided with the hermetically-sealed construction I that guarantees sealing between through hole and the outer surface of tube blank, also is provided with on the protective cover for inert gas to enter the air admission hole 53 in the protective cover and supply inert gas to flow out the venthole 54 of protective cover.Described hermetically-sealed construction I is the sealing ring 55 that is located on the blind end medial surface.In the present embodiment, air admission hole is located at the top, ring side of protective cover, and described venthole is located at the bottom, ring side of protective cover.
Described inner surface protective device comprises the barostat 6 in the pore that is located at pipe; the ring side of barostat is provided with the hermetically-sealed construction II that is sealed and matched with the pore wall; be provided with gas passage 61 in the barostat for the inert gas circulation; the barostat front end is provided with the air inlet 62 that is connected with gas passage; the sidewall bodies of barostat rear end is provided with the gas outlet 63 that is connected with gas passage, is provided with to keep the normally closed check configuration that makes the relative gas passage only export but no import of inert gas in gas outlet on the gas outlet.Described hermetically-sealed construction II is an elastic seal ring 64.Described check configuration is to be located on the lateral surface of barostat rear end and to seal the Elastic rubber duct 7 of gas outlet.In the present embodiment, elastic seal ring and barostat adopt same material to be wholely set.
In the foregoing description, the inert gas preferred nitrogen; Because pipe can oxidation take place after crystallizer cooling temperature is roughly at 40 ℃-100 ℃, so sealing ring and elastic seal ring and barostat adopt the high-temperature resistant rubber material to make, and Elastic rubber duct also adopts exotic material to make.In addition protective cover temperature that length also will consider pipe is set whether on the temperature that oxidation takes place, promptly protective cover will also be in the temperature of pipe the full cover of part on the temperature that oxidation can take place.
Concrete operation principle of the present utility model is as follows:
1) internal surface of bloom adopts constant voltage, the long-pending nitrogen protection of constant volume
Liquid metal in the smelting furnace forms pipe through crystallizer, pipe formation die tool after coagulation from the continuous casting mouth, with barostat from the pore of the front loaded pipe of pipe, and compressed nitrogen imported the gas passage from the air inlet of barostat, importing along with compressed nitrogen, make pressure increase in the gas passage, under the pressure effect of compressed nitrogen, Elastic rubber duct is backed down, compressed nitrogen overflows the pore that enters the barostat rear from the gas outlet, and barostat closely contacts the nitrogen at assurance barostat rear with the pore inwall and the air in barostat the place ahead completely cuts off.Constantly importing in the process of compressed nitrogen, the air pressure at barostat rear can be gradually greater than the atmospheric pressure in barostat the place ahead, barostat nitrogen gas pressure promotion by compression lower edge pore inwall forwards moves, the import volume of control compressed nitrogen, the temperature that makes barostat move to pipe are lower than when making its position that produces oxidation, stop to import compressed nitrogen, Elastic rubber duct shrinks, with the gas outlet sealing, compressed nitrogen continues to promote barostat and forwards moves, the pressure balance of two directions before and after barostat.In the normal level casting process; because the pressure of two directions remains balance before and after the barostat; along with pipe continuous casting length increases; the air pressure at barostat rear is descended; barostat pressure difference effect meeting is moved backward along the pore inwall and is reached balance again; the internal surface of bloom at barostat rear is under constant voltage, the long-pending protection of nitrogen gas of constant volume all the time, does not contact with air, and bonding is coiled horizontal casting copper and the copper alloy pipe inner surface non-oxidizing bright of weight 〉=1100kg.
2) outer surface of tube blank adopts the nitrogen circulation protection
Liquid metal in the smelting furnace forms pipe through crystallizer, pipe formation die tool after coagulation from the continuous casting mouth; enter protective cover; compressed nitrogen enters in the cavity that the outer surface of protective cover and pipe forms by air admission hole; normally cast process continuously at horizontal caster; by adjusting the flow of protective cover venthole; make the nitrogen of this cavity remain the state of circulation, positive constant voltage; the outer surface that guarantees pipe does not contact with air more than oxidizing temperature, thereby bonding is coiled horizontal casting copper and the copper alloy tube blank outer surface non-oxidizing bright of weight 〉=1100kg.
The utility model structural design novelty can reduce the loss of protective gas nitrogen to greatest extent, reduces the operating cost of horizontal casting; In normally continuous casting process of horizontal caster; remaining pipe does not all contact with air under the nitrogen protection in constant voltage when the generation oxidizing temperature is above; thereby bonding is coiled horizontal casting copper and the copper alloy tube blank outer surface non-oxidizing bright of weight 〉=1100kg, has realized copper and production of copper alloy tube high efficiency shortened process and industrialization.
Except that above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
