Problems solved by technology

[0003] The existing application process of ordinary charcoal in the copper horizontal continuous casting melting furnace has the following disadvantages: 1. During the casting process of copper in the horizontal continuous casting melting furnace, the copper liquid will contact with air to generate bubbles due to incomplete charcoal coverage, forming oxides, In addition, continuous slag removal is required. During the slag removal process, the exposed copper liquid is easy to absorb oxygen, and the copper billet crystallization is uneven, which affects product quality; 2. The traditional casting process uses ordinary charcoal to cover it. However, because charcoal is easy to burn quickly in the high temperature environment of copper liquid above 1000 ℃, it needs to be added repeatedly, and the cost is high; 3. The burning of a large amount of charcoal will easily make the operating environment worse, produce more waste, and increase environmental pollution.

Embodiment Construction

[0014] Through the description of the embodiments, the specific implementation of the present invention will be further described in detail.

[0015] The copper melting and casting processing method includes the following processing steps: feeding, covering, smelting, and slag removal; wherein, the melting furnace and the holding furnace are integrated equipment, and an overflow hole is hidden between the melting furnace and the holding furnace to facilitate the melting. The molten copper in the furnace enters the holding furnace.

[0016] Put the copper material in the smelting furnace, add a large piece of graphite phosphorus sheet for multi-layer covering, heat for smelting, stir for slag removal, remove the waste, and then transfer the copper liquid to the holding furnace for subsequent continuous casting; holding furnace The copper liquid in the medium is also covered with multi-layer graphite phosphorus sheets.

[0017] The large graphite phosphorus flakes cover the cop...

Abstract

The invention discloses a copper smelting processing method, including the following processing steps: feeding, covering, melting, and dragging residue, the covering is performed by completely covering a melted copper liquid with a graphite phosphorus piece, a large graphite phosphorus piece is used for covering in the copper processing smelting process, covering is comprehensive, oxygen isolation effect is effective, burning speed is slow, the production cost is effectively reduced, waste production amount is less, dragging residue is not needed, product quality is improved, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of copper melting and casting, in particular to a copper melting and casting processing method. Background technique [0002] In the copper horizontal continuous casting melting furnace process, charcoal is usually used for covering, so as to isolate the oxygen from the copper liquid, improve the crystallization quality of the copper casting slab, and reduce the oxygen content of the copper casting slab. [0003] The existing application process of ordinary charcoal in the copper horizontal continuous casting melting furnace has the following disadvantages: 1. During the casting process of copper in the horizontal continuous casting melting furnace, the copper liquid will contact with air to generate bubbles due to incomplete charcoal coverage, forming oxides, In addition, continuous slag removal is required. During the slag removal process, the exposed copper liquid is easy to absorb oxygen, and the copper ...
