製鋼工程の容器における熱損失低減技術

摘要

During steelmaking process, high temperature melt is processed through several facilities and containers, therefore the heat loss through steelmaking process is large. Progress of refractories and insulators have reduced the adverse influences by heat-insulation. The amount of heat loss through steelmaking process was estimated. Heat insulation with optimal design was attempted in molten iron and steel containers, heat loss through the steel shell was reduced by 25-45%.%製鋼工程は高温の溶銑•溶鋼を多段階のプロセスで扱うため，熱損失が大きい。近年，断熱材と耐火物の進歩により，断熱の設備容量や耐火物寿命への悪影響が軽微となり，熱損失低減が容易となった。今回，製鋼工程における熱損失を評価するとともにその低減方法を検討し，熱損失の大きい溶銑溶鋼輸送容器について断熱による低減を図った。その結果，鉄皮からの熱損失が25〜45%低減した。
