The specific embodiment
As shown in Figure 1, hot continuous casting system of the present invention, body of heater 3 by furnace shell 3 ', bell 2-3 forms, be installed on the base of furnace body 1, the bell folding motor 2 that is installed on the base of furnace body 1 drives column 2-1 rotation, drives bell 2-3 folding by spiral arm 2-2, it is characterized in that graphite crucible 5 is installed in the body of heater 3, the upper end of pressure bar 6 is installed in the spiral lifting mechanism of pressure bar drive motors 8 of driving pressure bar 6 liftings that are positioned at spiral arm 2-2 end, and the lower end of pressure bar 6 is inserted in the graphite crucible 5.
As Fig. 2, shown in Figure 3, a horizontal skirt 19 is installed on the sidewall of graphite crucible 5, the furnace chamber of graphite crucible 5 communicates with horizontal skirt 19, and a casting mold 10 is installed in the end of horizontal skirt 19, and casting mold heating furnace 9 is across on the type mouth of horizontal skirt 19 and casting mold 10.
As shown in Figure 1 and Figure 2 at haulage gear 14 ' be symmetrical in casting mold heating furnace 9 axial lines OO ' installation some groups of guide rollers 14 and pulling rolls 15, dummy ingot rod 16 is installed between relative guide roller 14 and the pulling rolls 15, and the left end of dummy ingot rod 16 is installed in the exit of casting mold 10 before the beginning drawing.Logical cooling water in the furnace shell 3 ' be welded into double-decker, interlayer with the air-tightness weld seam.
Form heat screen by graphite inner core and graphite felt as shown in Figure 1 and Figure 2 in graphite crucible 5, heating element heater is a circular graphite body, adopts delta connection, evenly distributes on every side along the hot-zone, and heating element heater is connected with external cabling by three first water cooled electrodes 21.Casting mold heating furnace 9 is by two second water cooled electrodes 21 ' be connected with external cabling.
As Fig. 1, shown in Figure 4, haulage gear 14 ' mainly partly form by servomotor, encoder, frequency converter, cycloidal planetary gear speed reducer, pulling rolls, hold down gag, base, slide rail, water tank and leading screw etc.
The concrete course of work of the present invention is: as shown in Figure 1, open bell 2-3, the metal or alloy raw material are sent in the graphite crucible 5, close bell 2-3 then.Body of heater is vacuumized, graphite crucible 5 begins heating, horizontal skirt 19 also begins heating, when the type mouth temperature of furnace body temperature and casting mold 10 satisfies required technological requirement, temperature control instrument is arranged to the automatic heat preserving state, after insulating process continues 40 minutes～1 hour, to graphite crucible 5 and horizontal skirt 19 inert gas injectings, open fire door 12, and carry out the centering adjusting of dummy ingot rod 16, open the ingot casting cooling water switch simultaneously, set hauling speed.Since after fire door 12 is opened, the of short duration decline of type mouth temperature meeting of casting mold 10, and temperature control instrument can send automatically to instruct and heat this moment, when type mouth temperature comes back to technological temperature, started the control system of pressure bar 6, allowed pressure bar 6 press down.When molten metal is full of horizontal skirt 19 by the time, start haulage gear 14 ', carry out casting process.When pressure bar 6 was depressed into the bottom of graphite crucible 5, casting process finished, and close fire door 12 this moment, makes furnace pressure return to atmospheric pressure.
