Five main points of copper belt production technology

Red copper strip high purity, fine tissue, low oxygen content. No porosity, trachoma, loose, good electrical conductivity, high precision of electroetching mold surface, after heat treatment process, no direction of the electrode, suitable for fine beating, fine beating, with good thermoelectric channel, processability, ductility, corrosion resistance and weather resistance. Good electrical conductivity, heat conduction, corrosion resistance and processing properties, is welded and brazed.

Today, Buck Copper industry technical personnel for you to brief the assembly process points of red copper belt:

1. Ingot heating. The copper ingot is simple to oxidize on the surface when heated, while the similar ingot without oxygen tends to seep oxygen when heated. Therefore, micro reduction should be used generally when heating (used for oxygen free copper, copper containing more oxygen is simple to supply "hydrogen disease" and will not be used) or neutral atmosphere, should maintain the positive pressure within the furnace. When heating, it should take rapid temperature rise and vasoconstrictor out of the ove  n.

2, hot rolling. the recent rolling of T2 guide copper strip casting ingot should adopt temperature, fast and enormous processing rate rolling to cut back extreme temperature oxidation as far as possible.

3, cold rolling. Copper has good plasticity and also the cold working rate can reach over 95% between two annealing periods. Therefore, intermediate annealing is mostly not required within the cold rolling process.

4. Annealing of finished products. Copper is simple to oxidize when returned, so it must be meted out in a very annealing furnace with a protective atmosphere.

5, cleaning and finishing. The surface of red copper strip is straightforward to alter color, so it should be cleaned and passivated in time. T2 guide copper belt is comparatively soft, measures should be taken (such as lining paper) to forestall scratches, cutting to carefully adjust the compression force of the tool to forestall indentation.
