The recycling of waste oxides at great lakes division, national steel corporation

摘要

This paper describes the design, construction, and startup operations of a briquetteing plant to recycle the revert dust, sludges and other materials generated from the iron and steelmaking processes. The specific plant constructed for National Steel Corporation's Great Lakes Division was designed to recycle 273,000 metric tons (300, 000 net tons) of integrated steel plant revert materials, such as BOP dust, blast furnace flue dust and sludge, and mill scale. The majority of the briquette plant production, about 80 percent, will recycle through the blast furnace and the remaining 20 percent through the steelmaking furnaces. This paper discusses the criteria used for plant design, construction, and startup. The plant design and construction period was 12 months with construction during the last 33 week period. The startup of the plant proceeded extremely well with the ramping up of production rates faster than the proposed startup plan. In addition, the blast furnace production was initiated using a newly developed blast furnace binder.
