AI Technical Summary

Technical Problem

The lack of specialized tools in the existing technology makes it difficult for continuous casting workers to accurately remove the slag strips in the crystallizer, which can easily damage the billet shell, affect the quality of the continuous casting billet and pose a risk of steel leakage.

Method used

A slag strip scooping device for continuous casting mold was designed, which includes a slag strip scooping rod, a slag strip scooping head, a slag strip scooping arm, a rotary wheel and other components. Through precise calculation and assembly, the slag strip can be quickly and accurately scooped out, reducing damage to the billet shell.

Benefits of technology

It achieves efficient and accurate removal of slag strips, reduces workers' labor intensity, improves the surface quality and production efficiency of continuous casting billets, and reduces disturbance to the molten steel surface.
