MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617098583 A) filed by Primetals Technologies Austria Gmbh on August 14, 2026, for Combined Casting And Rolling Mill Having Improved Productivity.
Inventors include Grosseiber, Simon; Preuler, Lukas; Schwarz, Gero; and Watzinger, Josef.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: A combined casting and rolling mill is initially operated in continuous operation in a known manner, so that the continuous casting mill and the rolling mill are coupled to one another by the cast metal strand (4). Presently relevant is a special operation which begins when the pouring of the liquid metal (1) into the continuous casting mold (2) is ended. The metal strand (4) is then still drawn off from the continuous casting mold (2), but at a lower draw-off speed (v2) at least at the beginning of the special operation. Furthermore, a last portion (17) of the metal strand (4) which, upon the transition into the special operation, is located in the continuous casting mold (2) and in an adjoining upper region of the strand guide (5) is cooled to a greater extent in the strand guide (5). An adjoining earlier portion (18) of the metal strand (4) is cooled as before or to a slightly lesser extent. The metal strand (4) is cut only after the termination time (t1). The cutting time (t5) is selected such that the remaining portion (23) comprises the last portion (17), which is cooled to a greater extent, and possibly a small part of the immediately preceding portion (18) of the metal strand (4). The entire part of the metal strand (4) lying in front of the cutting point (20) is rolled to form the metal strip with the normal strip thickness (d3N).
