Description

Process for the direct processing of electrolytically obtained Copper The subject of the invention is a method for direct processing of electrolytically obtained copper by rolling, drawing, pressing and the like.

Electrolytically deposited copper is porous and in this state not suitable for many purposes.

According to the invention, it is possible to produce electrolytically obtained copper objects to be processed on sheets, strips or the like of good quality without having to do this electrolytically recovered copper, as before, has remelted. You've got to be scientific Investigations of electrolytically obtained copper from a cold compression work subjected; but technically it is not possible to use electrolytic copper in a cold way flawless semi-finished products, such as B. sheets, strips o. The like. To produce, because with cold working the possibility of welding the individual crystals is not given. This then results in an uneven structure.

On the other hand, it was proposed to use electrolytic metal deposition by treating the objects covered with these precipitates under heated conditions To compact rollers and make them shiny.

You also have very thin electrolytic copper deposits several times during the electrolysis, each time after applying a very thin copper coating, Smoothed with agate stones or the like and thereby compacted at the same time. Also has you already have copper deposits, e.g. B. in the tube production, during the electrolytic Process subjected to a permanent mechanical smoothing in order to make them for to make further mechanical processing suitable. In this case, however, has the further mechanical processing took place in the cold state.

According to the invention, electrolytically produced copper objects, such as plates, rods or the like, in bright red heat, preferably in close to goo ° C, subjected to mechanical processing that varies according to the objects to be produced in rolling, drawing, pressing and the like. Man can in this way the porous and loose electrolytic structure in a state convict the one with regard to the technological properties of copper Material obtained from the usual cast blocks.

So you can z. B. a cathode after only the loose on it Sessile warts have been removed easily to a usable block roll out if this roll is bright red heat, preferably in the vicinity of goo ° C, is made. Such a cathode can also be used in the case of the aforementioned temperature easily compact by pressing.

It is advisable to avoid oxidizing flames in the heating furnace and to exclude the air, i.e. in a closed furnace with a reducing flame to work, possibly also to use an inert atmosphere.
