Abstract

Continuous casting of steel has nearly reached its saturation with approximately 80% continuous casting ratio worldwide. In order to cope with the high market requirements regarding product quality, low operation and maintenance costs, and high plant availability, steel companies are forced to invest in new equipment and to consider new technologies to match with the changing market situation. VAI has developed and successfully installed technological packages for the specific requirements of steel producers in order to meet above mentioned market demands. An overview of VAI’s latest status of technological solutions is given: Advanced technological packages like the DYNAFLEX hydraulically actuated oscillator, the hydraulic width adjustable mold (HYDROWAM), the MoldExpert - a tool to ‘look into the mold’ -, and the new on-line thickness adjustable SMART® segment with ASTC features (Automatic Strand Taper/ Thickness Control) are presented. On November 30, 2001, exactly 2 years after contract award the turnkey Continuous Casting Plant at Cosipa, Brazil was put into operation. The caster was quickly ramped up to a 3 shift operation within 2 weeks in mid December 2001. First operational results are discussed.
