Problems solved by technology

Adding a covering agent on the copper water surface for reduction and deoxidation is the main method to solve the problem of copper rod quality defects caused by oxidized inclusions, but the furnace fluid in the graphite crucible furnace is relatively static, which is not conducive to the floating and adsorption of oxidized inclusions. It is easy to affect the finished quality of the copper rod

Abstract

The invention discloses a molten copper smelting up-drawing process for controlling copper alloy inclusions. The process comprises the following steps that (1), a copper plate is cleaned; (2), the copper plate is smelted into molten copper, and a covering agent is added when the molten copper is smelted; (3), alloy elements are added into the molten copper for alloying, and ultrasonic treatment is carried out; (4), the content of a molten copper alloy in a melting furnace is detected, if the content is lower than the standard, an alloy is added for supplementation, if the content is higher than the standard, a copper plate is added, and when the content of the alloy meets the standard, the purpose of stabilizing the content of the copper alloy component is achieved by controlling the adding rate of the copper plate and the alloy; (5), soft argon blowing is conducted at the bottom of the melting furnace; and (6), an up-drawing method is adopted, specifically, the up-drawing method is adopted for producing a copper rod, and the molten copper in the melting furnace is electrified in the up-drawing process. According to the molten copper smelting up-drawing process, ultrasonic treatment is adopted, argon is softly blown from the bottom after the molten copper is alloyed, so that the inclusions in the molten copper float upwards, the stability of the cleanliness of the molten copper can be effectively guaranteed, meanwhile, the molten copper refining effect is improved by electrifying the melting furnace, and the inclusions are controlled from the source.

Description

technical field [0001] The invention relates to the technical field of metallurgy of nonferrous metals, in particular to an upward induction process of copper smelting for controlling copper alloy inclusions. Background technique [0002] Non-ferrous metal smelting is the general term for the metallurgical process of non-ferrous metals such as copper, aluminum and tin. Copper-based materials are divided into pure copper and copper alloys according to their composition content. Copper alloy smelting mainly uses high-purity cathode copper plates and other non-ferrous metals as raw materials, and uses different methods to smelt copper alloys. Modern copper alloy smelting mainly adopts the up-drawing method, and some dip-coating methods are used. The basic production process of the up-drawing method is to smelt the high-purity cathode copper plate into copper water in a graphite crucible furnace, then use the copper water as a raw material, add specific non-ferrous metals to sm...
