Types of Steel Rolling Mills: Exploring Different Techniques
Steckel Mills. Steckel mills are a combination of hot rolling and cold rolling processes. They allow for the production of steel strips and plates directly from cast slabs, eliminating the need for separate hot and cold rolling stages. Steckel mills are known for their flexibility and cost-effectiveness in producing a wide range of steel products.
