Smelting furnance of copper tube

[0014] like figure 1 As shown, the copper tube smelting furnace of the present invention includes a melting furnace 1, a holding furnace 2, an upper drawing mold 3, a crystallizer 4, a traction motor 6, a speed regulating device 5, and a cooling water system and an electrical system that are conventionally provided, All are installed on the body 8 according to the conventional technology, the melting furnace 1 and the holding furnace 2 are connected in parallel, and the melting furnace 1 is smaller than the holding furnace 2; 10 crystallizers 4 are installed in two rows on the body 8, 5 in each row, crystallization The lower end of the device 4 is connected with the upper drawing mold 3, and the upper end is connected with the traction motor 6 through the copper tube 7 extracted from the crystallizer 4. The speed regulating device 5 is in contact with the copper tube 7 and connected with the traction motor 6 . like figure 2 As shown, the speed regulating device 5 includes a nu

[0016] The structure of the copper tube smelting furnace of this embodiment differs from that of Embodiment 1 in that nine crystallizers 4 are installed in two rows on the body, with five in one row and four in the other.

[0017] When the copper tube smelting furnace of each of the above embodiments is working, the treated electrolytic copper plate is added to the melting furnace 1 for melting, and after the molten copper is left to stand in the holding furnace 2, it enters the crystallizer 4 through the upper drawing mold 3 to crystallize out Copper tube, the copper tube 7 of crystallization is pulled out by traction motor 6 again. In this production process, the choice of traction speed is directly related to the output and quality of products. For this reason, the copper tube smelting furnace is equipped with a speed regulating device 5, through which the speed of the traction motor 6 is adjusted to realize the rationalization and normalization of the traction speed, and the
