Process Model Suite for Caster Process Optimization

The Process Model Suite is a cutting-edge software solution designed to optimize the casting process by enhancing precision, flexibility, and efficiency. In the steel industry, achieving optimal product quality while maintaining high production rates is a constant challenge. The Process Model Suite addresses these challenges by providing advanced tools for modeling, simulating, and optimizing the continuous casting process. The comprehensive automation solution gives caster operators unparalleled control and precision. The Process Model Suite can be installed on any continuous casting machine as a standalone solution to ensure flexibility for diverse operational needs. It is also part of the comprehensive CC Optimizer.

The Process Model Suite uses the following three advanced metallurgical models to provide unmatched accuracy and control in continuous casting operations:

• DynaPhase calculates temperature-dependent material properties based on actual steel compositions to ensure precise thermal calculations and liquidus/solidus temperature determinations.
• Dynacs 3D calculates the real-time, three-dimensional thermal profiles of the hot strand, including the solidification point, mushy zones, and critical edge temperatures. It also calculates water flow setpoints to ensure a stable strand surface temperature profile. The calculated thermal tracking information serves as input for DynaGap Soft Reduction 3D. A powerful built-in offline simulation and replay feature supports the development and testing of optimized cooling strategies.
• Dynacs 3D is tailored for slab and bloom casters.
• For billet and bloom casters, DynaSpeed calculates residence times and cooling zone water flow setpoints to ensure consistent strand quality.
• DynaGap Soft Reduction 3D automatically adjusts the setpoints for each segment to optimize the roller gap according to the calculated thermal profile. It forces thickness reduction at the critical final solidification point to ensure optimal roll gap adjustment and minimize shrinkage defects. This feature enables an automated quick change in thickness to ensure optimized slab quality for any slab thickness within the design range.

The Process Model Suite for continuous casting machines delivers real-time insights, powerful offline simulation tools, and seamless integration into automation environments, whether it is integrated into the CC Optimizer solution or installed as a standalone system. This flexibility allows steel producers to adapt to demanding production requirements while maintaining consistent quality standards.
