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 ...
Optimization of a Cold Rolling Mill with a White P High Speed X-ray Thickness Gauge aper Christopher Burnett, Thermo Fisher Scientific, Mount Airy, MD, United States Key Words Abstract Thickness Gauge, X-ray The high speed production achieved by modern cold rolling mills requires reliable and absorption, Automatic robust thickness sensors. The Automatic Gauge Control (AGC) systems and hydraulic Gauge Control, non-contact, actuators in place today are capable of reacting to strip changes within just a few instrumentation standards milliseconds so accurate measurements must be supplied with comparable speed. In order to aide process control engineers as they optimize the throughput ...
Introduction Of Cold Drawing Process of Seamless Pipe factory The seamless tube is a long strip of steel with a hollow section and no seams around it. Its characteristics: First, the thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, the processing cost of the seamless pipe factory will increase greatly; secondly, the seamless pipe The process of the plant determines its limited performance. Generally, the seamless steel pipe has low precision: uneven wall thickness, low brightness inside andoutsidethe pipe, high fixed-length cost, and pitting and black spots on the ...
