Problems solved by technology

Not only the labor intensity is high, but also the furnace cover wears a lot, and needs to be replaced irregularly, which increases the production cost, especially when the furnace cover is opened to feed the furnace, the air will naturally enter the furnace, which will easily cause the copper water to oxidize or even overburn, seriously Affect the quality of downstream products

Embodiment Construction

[0013] refer to figure 1 , figure 1 It is a structural schematic diagram of a specific embodiment of the present invention.

[0014] like figure 1 As shown, an electric heating melting furnace feeding port air automatic isolation device includes a charging port 1, a charcoal feeding machine 2 is arranged on the upper left side of the charging port 1, and a certain amount of charcoal 3 is stored in the charcoal feeding machine 2, and the charcoal 3 is cut into unequal lengths smaller than the diameter of the feed port, start the charcoal feeder 2, place the charcoal 3 in the feed port 1, make it evenly fill the feed port and become tightly covered Layer 5 of charcoal on top of melted copper water.

[0015] As a further improvement of the above technical solution, it also includes setting a charcoal thickness detector 4 on the left side of the feeding port 1, so as to add the charcoal 3 in time to ensure that the charcoal 3 always maintains a certain thickness.

Abstract

The invention discloses an automatic air isolation device for a feeding port of an electric heating smelting furnace. The automatic air isolation device comprises the feeding port. A charcoal feeding machine is arranged at the upper left position of the feeding port. A certain amount of charcoal is stored in the charcoal feeding machine. The charcoal is cut into segments with the unequal lengths smaller than the diameter of the feeding port. The charcoal feeding machine is started, the charcoal is placed in the feeding port, the feeding port is evenly filled with the charcoal, and the charcoal becomes a charcoal layer tightly covering melting molten copper. The automatic air isolation device is simple and scientific in design and low in cost; the heating process becomes more convenient and faster, the labor intensity of workers is further relieved, and it can be guaranteed that air and the molten copper in the electric heating smelting furnace are automatically isolated at any time; and meanwhile due to the fact that the charcoal serving as a reducing agent in the oxidization process can further reduce the oxygen content in the molten copper, the product quality of a copper material can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of upward-drawing oxygen-free copper rod continuous melting and continuous casting production, in particular to an automatic air isolation device for a feeding port of an electric heating furnace. Background technique [0002] The copper up-drawing method is mainly used to produce long-length bright oxygen-free copper rods and other various special-shaped materials. Compared with the traditional copper ingot rolling to produce black copper rods, the copper material up-drawing method is used for copper production and processing, which has the advantages of With the characteristics of strong production continuity, short process, stable product quality, low unit energy consumption, flexible and diverse production varieties and specifications, it is currently a relatively advanced production process for the production of large-length copper busbars and other heterosexual copper blanks. [0003] In order to reali...
