Automatic air isolation device for feeding port of electric heating smelting furnace

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...

AI Technical Summary

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
