Improving the Mechanism for Emergency Extraction of the Leveling Rod in the Coke Ejection System at Ural Steel

In the coke ejection system serving the ovens in coke batteries 1, 3, 4, and 6 in the coke shop at Ural Steel, a manual winch mounted beside the main drive is used to remove the leveling rod from the coke oven in the event of drive failure. Two workers cannot complete this task in less than an hour. Replacement of the manual winch by an electromechanical winch is proposed to automate and speed up the extraction of the rod in the coke ejection system and to improve the reliability of the emergency rod-extraction mechanism. Modernization of the emergency extraction mechanism reduces unplanned downtime and the cost of coke; increases the profitability and coke output; and eliminates manual labor. The capital investment may be quickly earned back.
