About Us

Developing an innovative Software for Precise Real-Time Modeling of Rolling Process

Our Mission

For steel industries, an emphasis is given to developing finite element-based real-time models for the prediction and control of roll force, roll power, roll torque, strip temperature, strip profile, flatness, etc.

Our History

Founded in 2005, the CAPEC has been devoted to enhancing process design and control in metal rolling, via the application of CAPEC’s state-of-the-art technology to the related industries. The CAPEC’s members are proud of their highly advanced finite element simulation and optimization capability, which enabled a precision analysis of the detailed aspects of deformation, heat transfer, fluid flow, and phase transformation occurring in metal forming, including flat rolling, shape rolling, forging, extrusion, and other forming practices such as continuous casting, wire production, and leveling
