Equipment & Maintenance
Blast Furnace No. 3 at the Zaporozhye, Ukraine integrated steel plant operated by Zaporizhstal is being modernized in 2016-2017. The Ukrainian company is targeting increased production and availability for this furnace, and this is to be achieved through the application of new technology. After careful evaluation of available technologies, Zaporizhstal awarded a contract for the furnace’s Top Charging Unit to Danieli Corus. The main focus during the development of this latest generation charging technology has been availability and maintainability of equipment. The charging chute, which has proven to offer optimum control over the distribution of raw material on the stockline, is tilted and rotated using proven, more robust solutions than traditional designs. Reliability of the chosen charging device is pivotal, as it largely determines availability of the blast furnace and exchange of e.g. gearboxes or drive motors may require long outages. This article describes the DANCU (Danieli Charging Unit) - a robust hydraulic system. This chute type charging unit has only four major moving parts, none of which is complex or vulnerable. It also describes main project challenges - the use of hot sinter and the short project schedule.
