Benefits of technology

This technology ensures that there're no damaging or instability when carrying it around for use in producing high-quality steel strips. It also improves its overall performance by adjusting the work positions and forms of both sides of the metal band being produced. Overall, this new technology helps produce stronger and sturdy products while reducing costs associated with production processes.

Problems solved by technology

This patented technical problem addressed in the present describes how control over the location of the end seals within a twin roll caster machine allows for better quality formation of thinner strips with fewer defects compared to existing methods like single pass tape continuous casting.

Abstract

The invention provides a method for controlling side seal of twin roll thin strip casting. The method comprises the following steps: the number and size of burrs on the edge part of a cast belt are detected in real time by adopting a detection device; according to detection feedback data and target data comparison, a side seal plate support system regulates the working height of a side seal plate, so that the height difference of the groove on the lower part of the side seal plate and the freezing point (kiss point) of the cast belt is kept to be between 0.1 and 2mm, meanwhile, the side seal plate is kept to be constantly contacted with the end face of a crystal roll so as to improve the edge part quality of the cast belt. The working position of the side seal plate is correspondingly regulated by detecting the edge part quality of the cast belt, so that the quality defect of the edge part of the cast belt is reduced, the cast belt quality is improved, abrasion of the side seal plate can be reduced, and the requirement on long term casting of thin strip continuous casting can be met. The side seal plate support control system comprises a position control mode and a pressure control mode, and is suitable for the whole casting process.
