- Scope: Engineering, Procurement and Construction
Engineering, procurement and structural/mechanical erection services for the iron oxide screening, storage and reduction furnace feed system and product conveying, storage and reclaim, and shiploading feed conveyor system at the Caribbean Ispat Limited Direct Reduction Facility III (DR3).
The oxide feed system consists of a series of conveyors which receive iron oxide from existing mobile hoppers, conveyors and a shipunloader. The oxide is then conveyed to either a stacker/reclaimer for storage or to a set of oxide screens. The screened fines are conveyed to a stockpile. The sized oxide is stored in day bins which have weigh belt feeders on the discharge of each bin.
The oxide is then conveyed to the reduction furnace. The DRI product is then conveyed from the furnace to the product storage bins. The bins are equipped with vibrating feeders which feed the DRI product to a screening station which send the screened fines to a bin for truck loadout. The overs are conveyed to either the existing meltshop, existing product storage building or the new product storage building. The product storage consists of a traveling tripper/bridge structure and reversing shuttle conveyor system.
The DRI product is automatically stored into four stockpiles within the product storage building. The DRI product is then reclaimed from the product storage building via a series of slide gates and conveyors to the dock conveyor/tripper for shiploading.
This project required the use of gas tight slide gates for the product storage bins and product reclaim storage building reclaim slide gates due to the high reactivity of the DRI.
