Title: Development of automatic operation system for coke oven machines at Yawata Works of Nippon Steel Corporation

Abstract

The coke plant is a working environment involving heavy dust emissions, high heat and demanding physical labor. The labor-saving operation of the coke plant is an essential issue from the standpoints of not only improvement in working environment, but also reduction in fixed cost by enhancement of labor productivity. Under these circumstances, Nippon Steel has implemented the automation of coke oven machines. The first automatic operation system for coke oven machinery entered service at Oita Works in 1992, followed by the second system at the No. 5 coke oven battery of the coke plant at Yawata Works. The Yawata automatic operation system is characterized by the installation of coke oven machinery to push as many as 140 ovens per day within a short cycle time, such as a preliminary ascension pipe cap opening car and cycle time simulator by the manned operation of the pusher, which is advantageous from the standpoint of investment efficiency, and by the monitoring of other oven machines by the pusher. These measures helped to reduce the manpower requirement to 2 persons per shift from 4 persons per shift. The system entered commercial operation in March, 1994 and has been smoothly working with an average totalmore » automatic rate of 97%. Results from the startup to recent operation of the system are reported below.« less
