Improvement of Yield at No. 8 Rod Mill in Kakogawa Works, Kobe Steel, Ltd.

Abstract

In 1980, we have improved the yield ratio up to 99.0% in No. 8 wire rod mill, Kakogawa Works, Kobe Steel, Ltd.
Generally, the yield ratio yaries with types of mill, including steel grade, rod size and coil weight. From this point of view, No. 8 wire rod mill has a lot of advantages.
In addition, we continued to make efforts to reduce yield loss such as scale loss, crop loss and cobbles. The yield ratio of 99.0% was accomplished by the accumulation of the above J. K. activities.
