Production method of copper plate and strip

There are two main production methods for high-precision copper plates and strips, one is the large ingot hot rolling high-precision cold rolling method, and the other is the horizontal continuous casting coil billet high-precision cold rolling method.
The basic modern technology of high-precision cold rolling is: a four roll or six roll high-precision rolling mill is used for cold blooming and cold intermediate rolling; To achieve precise tolerances in finished products, rolling is generally used. The intermediate annealing adopts a hood type protection annealing furnace; The finished annealing adopts an unfolded protective gas annealing furnace. To ensure excellent plate shape, the finished strip requires a bending and straightening process.
