Technical Field
The invention relates to the technical field of metallurgy, in particular to copper and copper alloy ingot casting equipment with nitrogen protection.
Background
The smelting temperature of red copper, phosphorus deoxidized copper, oxygen-free copper, silver copper, high copper and white copper alloy is generally 1120-1350 ℃. At high temperature, the surface of the alloy cannot form a compact protective film, and is extremely easy to oxidize to form thicker oxide skin, so that the quality of the cast ingot and the subsequent processing are influenced. When oxygen-free copper is produced, oxygen can also permeate into cast ingots, and the performance of the products processed later is affected. At present, no protective measures are basically taken on the outer surface of the cast ingot in the casting process at home and abroad, and the surface is often subjected to serious oxidation phenomenon, so that the subsequent processing is adversely affected. The oxide skin increases the abrasion of the extrusion cylinder, the extrusion rod and the perforating needle, so that the service life of the extrusion die is greatly reduced. The scale is pressed into the processed product to cause product defects, and when severe, the product is scrapped. Oxidation of metallic copper can result in metal loss and increased production costs.

When the water storage tank No. 106 is filled with water, the water storage tank No. 3 is filled with water through the opening at the communication position of the water storage tank No. 3 and the water storage tank No. 106, when the upper water cooling device 105 moves upwards, the plug 304 is separated from the water leakage hole 301, water in the water storage tank No. 3 falls into the annular funnel 302 through the water leakage hole 301 and enters the water storage tank No. two 203 through the opening 305, at the moment, a part of water source of the water storage tank No. two 203 is water in the water storage tank No. 3, and a part of water source of the water storage tank No. two is water in the water injection pipe No. two 209, so that the water injection speed of the water storage tank No. two 203 is faster.
After the copper ingot is cooled, the first hydraulic cylinder 401 is started to enable the copper ingot to enter the sealing chamber 5, the other first hydraulic cylinder 401 is started to enable the other dummy ingot head 404 to continue working, the first double-opening sealing door 501 is closed, the second double-opening sealing door 502 is opened, and the copper ingot is taken out.
The above description is of the preferred embodiments of the present invention, and any person skilled in the art may modify the present invention or make modifications to the present invention with the technical solutions described above. Therefore, any simple modification or equivalent made according to the technical solution of the present invention falls within the scope of the protection claimed by the present invention.
