The top and the bottom side surfaces of the protective cylinder 4 are both connected with cold and hot air pipes 3 for blowing cold and hot air into the protective cylinder 4 and mixing the cold and hot air.
The tundish 19 comprises a hearth 11, a furnace lining 12, a cooling water jacket 13, a rotating shaft 14, a liquid outlet 15, a primary winding 16, a secondary winding 17 and a power supply 18; the furnace lining 12 is arranged outside the furnace hearth 11 in a covering mode, the rotating shaft 14 is arranged on a trunnion of the tundish, the liquid outlet 15 is arranged at the top of the furnace hearth 11, the primary winding 16 and the secondary winding 17 are arranged at the bottom of the furnace hearth 11, the cooling water jacket 13 is arranged outside the primary winding 16 and the secondary winding 17, and the primary winding 16 and the secondary winding 17 are connected with the power supply 18. The tundish 19 is heated by a power frequency induction furnace, the copper liquid 20 in the hearth 11 is heated by the electromagnetic induction principle, and the copper liquid rolls through the melting channel, so that the temperature and the uniformity of the copper liquid can be accurately controlled, and the phosphorus content and the oxygen content uniformity can be controlled.

The process comprises the following steps: the system for producing TP2 copper tube casting blanks by continuous casting with one shaft furnace, two tundish furnaces and four horizontal casting furnaces has the advantages that the heat efficiency of the shaft furnace is more than 60 percent, and when a large amount of electrolytic copper is melted, the system has the outstanding advantages of energy conservation and no damage to the original metal components in the electrolytic copper. The technical difficulty of producing the copper pipe casting blank by adopting the shaft furnace is the control of the phosphorus and oxygen contents, and the phosphorus content of the TP2 copper pipe product is controlled to be 180-220ppm and the oxygen content is less than 10ppm, so the phosphorus and oxygen are required to be adjusted. The combustion system of the shaft furnace adopts a completely premixed reductive combustion mode, controls the proportion of oxygen in natural gas and air on line, can adjust the combustion atmosphere, and adopts micro reductive atmosphere combustion, namely, the natural gas is in micro excess, so that the oxygen in the air is completely combusted, the micro excess natural gas generates reductive gas, and the molten copper is protected from being oxidized instantly. The tundish 19 is heated by a power frequency induction furnace, and the copper liquid rolls through the melting channel, so that the temperature and the uniformity of the copper liquid can be accurately controlled, and the uniformity of the phosphorus content can be controlled; the graphite phosphorus sheets are added on the surface of the casting furnace for covering, so that the oxygen content of the molten copper can be prevented from rising.
The technological process of the TP2 copper tube billet horizontal continuous casting is that firstly, a pouring basket 19 is poured to lead the molten copper liquid 20 to flow into a holding furnace 22 through a launder 21. The molten copper 20 flows into the crystallizer 23 under the action of static pressure, and starts to crystallize and solidify into a blank shell with certain strength when meeting the inner wall of the crystallizer which is strongly cooled by primary cooling water. And then the cast product is drawn out of the crystallizer by a tractor 25, the outer surface of the TP2 copper pipe cast blank 27 is directly sprayed and cooled by secondary cooling water of a secondary cooling system 24, and the shearing machine 26 shears the cast product when the length of the TP2 copper pipe cast blank 27 meets the requirement, and then the next procedure is carried out. In the continuous drawing process, the copper-free liquid is continuously supplemented into the crystallizer under the action of static pressure, and the continuously crystallized and solidified blank shell is drawn out, so that the horizontal continuous casting process is formed.
