THE first ring-rolling mill designed and built by Siempelkamp has passed its crucial test at its initial startup at the Krefeld plant. In July, Siempelkamp manufactured the first rings made of steel with the rolling mill, which will be delivered to the Russian JSC Metallurgical Plant Electrostal shortly. The ring rolling mill with maximum radial and axial pressing forces of 6,300kN each enables the precise manufacturing of rings with an external diameter of up to 2,500mm and a height of up to 600mm.
