As improvement, described cast tube is divided into two sections, the caliber of its short-and-medium cast tube is greater than the caliber of long cast tube, the two difference is the pipe thickness of graphite liner pipe, short cast tube is welded and fixed with long cast tube the shoulder hole that rear formation supplies graphite connecting pipe and graphite liner pipe to insert, graphite connecting pipe and graphite liner pipe are coaxially arranged in short cast tube successively, and the inner end of graphite connecting pipe and the end face of long cast tube offset fixing, and the internal diameter of graphite connecting pipe is consistent with the internal diameter of graphite liner pipe, long cast tube.
As improvement, the copper liquid one end that enters of described water collar forms the internal thread extending internally, with be provided with corresponding externally threaded short cast tube and be connected, the inwall of short cast tube is provided with internal thread, the outer surface of graphite liner pipe is provided with corresponding external screw thread, the mode that the inner end of graphite liner pipe is threaded connection is connected with short cast tube, and the other end stretches out water-cooled and is inserted in copper liquid.
As improvement, the described carborundum protective sleeve directly sticky water-cooled that is enclosed within is inserted in outside one end of copper liquid, offers the through hole placing for graphite liner pipe at the end face center of carborundum protective sleeve.
Improve, described long cast tube is that 1100～1105mm, short cast tube are 250～255mm again, and the length of graphite liner pipe is that 175～185mm, internal diameter are 8～12mm; The length of graphite connecting pipe is 175～185mm, is 1350mm～1355mm thereby make the total length of graphite crystallizer.
Improve, described cast tube is the high-purity copper tube of T2 again, and the tie point of cast tube and graphite connecting pipe is stepped ramp type.
Compared with prior art, the utility model has the advantage of: between graphite liner pipe and cast tube, add a moderate length and be conducive to the graphite connecting pipe for increasing a cooling effect, so just avoid copper melts directly to contact with cast tube, make copper liquid be cooled by graphite connecting pipe and solidify, solve the rich surface zinc problem of above drawing copper cash (bar) base, improve lumber recovery and the end product quality of follow-up wire stretching, the cold-forming property of material is got a promotion.The utility model is simple in structure, good cooling results, has not only alleviated labor strength, and graphite connecting pipe only needs one, easy installation and removal, has saved production cost greatly, and the product colour obtaining is for golden yellow, bright in color, smooth surface, steady quality is reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the graphite crystallizer that a kind of Continuous Up casting is used, comprise crystallizer plug, water collar 2, graphite connecting pipe 4 and graphite liner pipe 3, crystallizer plug is the cast tube that inner chamber 11 is vacuum, the material of cast tube is the high-purity copper tube of T2 with better conductivity of heat, cast tube is divided into 12 two sections of long cast tube 1 and short cast tubes, the caliber of short cast tube 12 is greater than long cast tube 1 caliber, its difference is graphite liner pipe 3 wall thickness, water collar 2 is coated on outside short cast tube 12, graphite liner pipe 3 and graphite connecting pipe 4, what long cast tube 1 was coaxially located in water collar 2 enters copper liquid one end, graphite connecting pipe 4 is arranged between graphite liner pipe 3 and long cast tube 1 to increase cooling effect, wherein the total length of cast tube is 1350mm～1355mm, long cast tube is 1100～1105mm, short cast tube is 250～255mm, the length of graphite liner pipe 3 is 175～185mm, internal diameter is 6～12mm, the length of graphite connecting pipe 4 is 175～185mm, and the internal diameter of graphite connecting pipe 4 is consistent with the internal diameter of graphite liner pipe 3, long cast tube 1, the copper liquid one end that enters at water collar 2 is provided with the internal thread that moulding extends internally, with be provided with corresponding externally threaded short cast tube 12 and be connected, the inner end of one end of long cast tube 1 and short cast tube 12 is welded and fixed, short cast tube 12 is welded and fixed with long cast tube 1 shoulder hole that rear formation supplies graphite connecting pipe 4 and graphite liner pipe 3 to insert, graphite connecting pipe 4 is set in short cast tube 12, one end is connected with 3 sealings of graphite liner pipe, the other end is connected with long cast tube 1 sealing, and long cast tube 1 is stepped ramp type with the tie point of graphite connecting pipe 4, make graphite connecting pipe 4 more firm, be difficult for loosening, the inwall of short cast tube 12 is provided with internal thread, and the outer surface of graphite liner pipe 3 is provided with corresponding external screw thread, and the mode that the inner end of graphite liner pipe 3 is threaded connection is connected with short cast tube 12, and the other end stretches out water collar 2 and enters copper liquid, carborundum protective sleeve 5 directly sticky be enclosed within water collar 2 enter outside, copper liquid one end, offer the through hole placing for graphite liner pipe 3 at the end face center of carborundum protective sleeve 5.
When casting, the vertical insertion in molten copper liquid of graphite liner pipe 3 of crystallizer rises to certain altitude according to siphon principle copper liquid in evacuated graphite liner pipe 3; When copper liquid enters cooling due to outside cooling water 6 of graphite connecting pipe 4, copper liquid is cooled and solidifies.Meanwhile, draw-gear is also ceaselessly drawn the copper bar having solidified from above.Temperature when copper bar leaves crystallizer is about 100 DEG C, and crystallizer is called once cooling to copper bar indirect cooling, and copper bar leaves that to be called secondary by heat loss through radiation after crystallizer cooling.Because copper liquid is in the interior cooled and solidified of graphite connecting pipe 4, avoid contacting with the direct of cast tube, so just avoid the excessive and enrichment of zinc, solve the rich surface zinc problem of above drawing copper cash (bar) base, improve lumber recovery and the end product quality of follow-up wire stretching, the cold-forming property of material is got a promotion.
