A method for melting copper in a power frequency furnace

Abstract

The invention discloses a method for melting copper through a line frequency furnace. The method comprises the following steps that 1, a waste copper piece and waste are subjected to primary treatment; 2, screening is carried out; 3, classification is carried out; 4, accessories are fed into furnaces, wherein the accessory I, the accessory II and the accessory III are fed into the shaft furnace, the open-hearth furnace and the line frequency cored copper melting copper to be refined, and a product I, a product II and a product III are obtained; 5, the product I and the product II are transported to a copper continuous casting and rolling unit for casting treatment, a steel rod is obtained, and the product III is placed in a pig casting machine to be machined and treated, and a copper ingot is obtained; and 6, the steel rod in the step 5 is drawn, and a qualified copper piece is obtained. The method for melting copper through the line frequency furnace achieves energy saving and is environmentally friendly, and manufactured steel is good in quality.

Description

technical field [0001] The invention relates to a method for melting copper in a power frequency furnace, and belongs to the technical field of preparation of recycled copper. Background technique [0002] The continuous expansion of smelting and processing enterprises in my country has led to an increase in the demand for raw materials. my country is a big consumer of copper, and copper resources are seriously insufficient. Domestic scrap copper resources are limited, and the contradiction between supply and demand is becoming more and more prominent. The demand for raw materials of the factory will be more and more dependent on scrap copper. Scrap copper is the raw material of recycled copper. It comes from various fields such as social production, circulation, and consumption. It is a multi-category and complex component. The raw material of copper can obtain better copper materials by classifying and processing scrap copper; but in the prior art, the processing of scrap co...

[0002] The continuous expansion of smelting and processing enterprises in my country has led to an increase in the demand for raw materials. my country is a big consumer of copper, and copper resources are seriously insufficient. Domestic scrap copper resources are limited, and the contradiction between supply and demand is becoming more and more prominent. The demand for raw materials of the factory will be more and more dependent on scrap copper. Scrap copper is the raw material of recycled copper. It comes from various fields such as social production, circulation, and consumption. It is a multi-category and complex component. The raw material of copper can obtain better copper materials by classifying and processing scrap copper; but in the prior art, the processing of scrap copper includes several steps of screening, sorting and refining. , using a fixed reverberatory furnace for energy-saving processing, the heat loss in the process is more, and the energy-saving effect is not good
