Problems solved by technology

[0004] At present, in the domestic non-ferrous metal processing industry, most manufacturers produce copper tubes by horizontal continuous casting. Many; some of them are produced by the upward-leading continuous casting method, and the number of continuous casting heads is limited (mostly two to five-strands in China), and the output is low (about one-third of that of the upward-leading method). Disadvantages such as large power consumption and high overall cost

Embodiment 1

[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...

Embodiment 2

[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 t...

Abstract

The invention discloses a red copper tube melting furnace which comprises a melting furnace, a holding furnace, an up-drawing furnace, crystallizers, a traction machine, a speed regulating device, a cooling water system and an electrical system that are all arranged on a machine body according to general technologies, wherein, the melting furnace and the holding furnace are communicated in parallel and the crystallizers are connected with the holding furnace by the up-drawing furnace. The invention is characterized in that 8-10 crystallizers are divided into two rows and arranged on the machine body, the lower ends of the crystallizers are connected with the up-drawing furnace and the upper ends thereof are connected with the traction machine by a red copper tube. The red copper tube melting furnace of the invention ensures that the daily output is increased from the original 6 tons to 8 tons under the condition of the same electrical furnace power, the using efficiency of the machine can be brought into play, in addition, the service life of the device can not be influenced, the energy resource consumption can be reduced and more than 1600 degrees electricity can be saved one day.

Description

technical field [0001] The invention relates to a copper tube smelting furnace, in particular to a smelting furnace capable of leading upwards for continuous casting of copper tubes, belonging to the field of metallurgical machinery. Background technique [0002] The upward-drawing continuous casting system was developed by Outokumpu Company of Finland in the late 1960s. It is mainly used for the production of oxygen-free copper pipes and was put into industrial production in 1970. Its production principle is to use immersion negative pressure to suck the molten metal into the crystallizer, and cool it once in the crystallizer, and then enter the secondary cooler for cooling. [0003] The application number is 021117780, and the Chinese invention patent titled "A Composite Shell Induction Melting Furnace" discloses an induction melting furnace. The shell has two layers of a steel outer shell and an aluminum inner shell fixed together. The left and right halves pass through ...
