1. Brief Introduction
Cold rolled metal composite basic principle will require two or more metals composite according to a certain mixture ratio and requirements, into the mill rolling compound, in mill under strong pressure, the composite metal plate and strip plastic deformation occurring in the whole section, prompted to be composite surface deformation, clean, activation, along with the formation of the planar metallurgical bonding. The basic requirement of rolling composite is a strong pressure of rolling equipment and production of composite panels with professional technology.
2. Production scale: 10000 tons / year
