Problems solved by technology

[0002] With the development of society and economy, the demand for copper is increasing, and the demand for copper products, especially copper rods with a diameter of 8mm, is increasing, and the quality of copper products affects the performance in the market. In the existing production process, The service life of the melting furnace itself, when it enters rolling after casting, due to the high temperature of the slab and the inconsistent speed of the slab entering the rolling mill, the production consistency of the product is not good enough, the defective rate is too high, and the cost is high

Embodiment Construction

[0013] Embodiments of the present invention will be described in detail below.

[0014] A kind of 8mm diameter hypoxic copper rod production method, comprises the following steps:

[0015] S1. Ingredients: according to the methods described in GB / T5152 and YS / T464, the chemical composition of the electrolytic copper raw materials is tested, and the electrolytic copper raw materials with a Cu mass fraction of not less than 99.996% are classified as effective raw materials, and the effective raw materials are fed in batches;

[0016] S2. Smelting: The raw materials are put into the furnace and melted to obtain molten copper. In order to protect the furnace, a replaceable protective plate is used at the entrance of the furnace to protect the entrance of the furnace. The molten copper passes through the outlet of the furnace and the upper launder to the holding furnace for refining, furnace and heat preservation The furnace temperature difference is controlled within 5°C, and the ...

Abstract

The invention discloses a production method of a low-oxygen copper rod with the diameter of 8 mm. The production method mainly comprises the steps of compounding, smelting, casting, rolling, cleaning and cooling, blow-drying, flaw detecting, waxing, rod winding and packaging. According to the production method, energy is saved, environment friendliness is achieved, and the production cost is low. The produced finished low-oxygen copper rod with the diameter of 8 mm is stable in performance, high in quality grade and product consistency and good in economic benefit.

Description

technical field [0001] The invention relates to the field of copper processing, in particular to a method for producing a low-oxygen copper rod with a diameter of 8 mm. Background technique [0002] With the development of society and economy, the demand for copper is increasing, and the demand for copper products, especially copper rods with a diameter of 8mm, is increasing, and the quality of copper products affects the performance in the market. In the existing production process, The service life of the furnace itself, when the cast slab enters rolling after casting, due to the high temperature of the slab and the inconsistent speed of the slab entering the rolling mill, the production consistency of the product is not good enough, the defective rate is too high, and the cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing a low-oxygen copper rod with a diameter of 8 mm, which ...
