Description of drawings
Fig. 1 is the structural representation of vertical segmentation casting unit of the present utility model.
The specific embodiment
Referring to Fig. 1, casting unit of the present utility model comprises crystallizer 1, and crystallizer 1 comprises graphite cannula 15, red copper cover 16 and water jacket 17 from inside to outside, forms water cavity between red copper cover 16 and the water jacket 17, and water jacket 17 is provided with water inlet 18 and delivery port 19.Below crystallizer 1, also comprise secondary water cooling plant 8 and No. three water cooling plants 5 successively, and seal closure 4 is installed being exported between No. three water cooling plants 5 of crystallizer 1.
Secondary water cooling plant 8 is annular or flat cavity, select for use which kind of shape to depend on the shape of ingot casting section, be that secondary water cooling plant and ingot casting section profile adapt, cavity side top has water inlet, has water jet 20 at annular housing 8 near the interior side-lower of ingot castings.No. three times water cooling plant 5 is preferably the casting well that is marked with nitrogenous air cooling water 13.Seal closure 4 upper ends are connected with the bottom of crystallizer 1, and the lower end of seal closure 4 is connected with the upper end of casting well 5.The sidewall of casting well 5 is inserted with a water inlet pipe 6, and water inlet pipe 6 is connected in the cavity of secondary water cooling plant 8, and is connected with nitrogen conduit on water inlet pipe, and valve 7 is installed on this nitrogen conduit.
Be provided with cooling water return duct 14 in the casting bottom, the cooling water of backflow reinjects through circulation and casts well.Below crystallizer 1, be provided with the copper ingot linear transducer.In seal closure 4, be provided with nitrogen content monitoring sensor 10.Be provided with nitrogen reflux control device 9 on seal closure 4, the output of nitrogen content monitoring sensor 10 is connected the signal input part of nitrogen reflux control device 9.
(promptly casting the position of platform 3) is provided with oxygen concentration sensor 11 in seal closure 4 outsides, and the signal input part of sensor 11 is connected with the control signal input of the fan 12 that is arranged on the seal closure outside 4.
The ingot casting process of using equipment of the present utility model is described referring now to Fig. 1:
Before beginning casting, dummy bar head 2 and crystallizer 1 aligned position, the borehole wall of crystallizer 1, seal closure 4 and ingot casting well 5, shaft bottom form an airtight space.At this moment, valve 7 is opened, and to ingot casting well 5 logical nitrogen, air is by 9 emptyings of nitrogen reflux control device in the well by valve 7, pipeline 6 and secondary water cooling plant 8 for the nitrogen source of the gas.When nitrogen content monitoring sensor 10 detects the discharging nitrogen gas concn and surpasses 99%, the floss hole of the automatic closing volume control device 9 of control system and valve 7, and the opening pressure of safety valve that recirculation control device 9 is set automatically is 1.5kg/cm.In casting process, along with nitrogen in the rising of water level in the well and the secondary water overflows, borehole pressure can progressively rise, and when pressure surpasses when setting safe pressure, recirculation control device 9 is opened pressure releases.Simultaneously, fan 12 is opened, and the nitrogen that purges well head reaches level of security.Begin to dash dress nitrogen from the ingot casting well and begin, the oxygen concentration sensor 11 under the casting platform measures the operating position oxygen content continuously.In case oxygen content surpasses setting range, buzzer warning, fan 12 is opened.
At the casting initial stage, copper liquid only contacts with crystallizer with ingot casting, and the primary cooling water in the crystallizer does not directly contact with metallic copper all the time, and primary cooling water does not directly impact copper ingot surface oxidation situation.Below the crystallizer shown in the figure three 1, copper ingot length measuring device 15 is installed, be used to detect the casting length and the casting speed of copper ingot, water pump start-stop, output, pressure of supply water that control secondary water cooling plant 8 uses.
