The ways to determine thickness deviation by measuring the thickness of the sheet at various points are shown. The reasons of rolls bending under the rolling pressure are ...
FUEL SAVINGS FOR BILLET REHEATING FURNACE THROUGH DOC TECHNOLOGY IN HSL 1 2 PAVITRA, G. SUCHITRA 1IV sem M.Tech Power and Energy System, EEE dept, BEC, Bagalkot 2 Professor, Power and Energy System, EEE dept, BEC, Bagalkot Abstract- Fuel-savings technologies can provide significant economic benefits to steel rolling mills. Billet reheating furnaces in hospet steel rolling mill consume approximately half of the furnace oil used to produce hot-rolled products. In this paper, Dilute Oxygen Combustion technology was extended to a billet reheating furnace. This flexible dilute oxygen combustion system provide significant fuel savings of 25% with no impact on ...
Abridged version KAWASAKI STEEL TECHNICAL REPORT No.14 ( March 1986 ) Special Issue on Stainless Steels Manufacturing Process and Properties of Stainless Steels Yutaka Ono, Hiroyuki Kaito Synopsis : At present in Kawasaki Steel Corp., commercial grade stainless steels such as type 430 or 304 are produced by the K-BOP-CC-tandem hot rolling mill-sendzimir cold rolling mill or tandem cold rolling mill processes. We developed an SS-VOD process in 1977, and various new ferritic stainless steels, such as ultra low carbon and nitrogen high chromium ferritic stainless steels, are produced by this process. They are extremely improved in wet and ...
