Copper Rod Casting Machine

2022-10-29 15:58:22

SUNY Group's continuous casting and rolling of copper rods in the form of a two-wheel rusting machine and a triangular mill. The initial copper ingot cross-section is 1300mm2, but now it is up to 2300mm2 with a theoretical capacity of 18t/h. The rolling hole pattern is a "triangular one-by-one circle" system. When the ingot cross-section is too large, two flat and one vertical roll stands are added in front of the original mill, and the billet is opened with a box type hole pattern, and the reduction rate of the box hole pattern is about 40%.

Main process equipment

Oxygen-free Copper Rod Casting Machine

Oxygen-free Copper Rod Casting Machine

It is used for continuous melting of electrolytic copper and can also be added to some clean copper scrap. It has high productivity and easy control without oxygen blowing, sulfur removal and wood reduction to obtain qualified copper solution. In the technical, economic superiority is reflective melting copper or electric furnace melting copper can not be compared, its main characteristics are summarized as follows.

(1) simple production tho, no need for "blowing oxygen to sulfur'' and "wood reduction"

(2) High production quality, because the furnace to maintain a reducing atmosphere, copper liquid oxygen content can be controlled in a very low range;

(3)High production efficiency

(4)Small footprint

(5) Convenient control, easy to start and stop the furnace;

(6)Good labor conditions, no pollution, high metal recovery rate.

(7) High thermal efficiency of the furnace, less fuel consumption, also can save Dali wood.

The proofer type elevated charging machine or forklift is used for charging. The fuel is required to be sulfur-free or contain very low flow, and the fuels currently used are natural gas, methane, propane, butane, petroleum, liquefied gas and naphtha.

In recent years, many plants have made certain improvements and refinements to the shaft furnace, such as automatic control of the transport and loading of electrolytic copper or copper scrap into the furnace, continuous measurement of oxygen content, premixing systems for air and gas, continuous monitoring of the hydrogen measurement system with automatic proportional adjustment, including the use of vacuum conduits for sampling to control for rapid gas analysis, etc.
