New Coal Based Ironmaking Process

Ironmaking Process The ironmaking process in the blast furnace is a heat and mass transfer process, and the furnace can be divided into different zones according to physical and chemical state of the feed and temperature.

Hydrogen steelmaking for a lowThis process would replace coal with hydrogen for the direct reduction of iron, combined with an electric arc furnace. It would be almost completely fossil-free, and if fully deployed, Sweden could see a 10% reduction in its greenhouse gas emissions. The concept is called Hydrogen Breakthrough Ironmaking Technology, or HYBRIT for short.Advantages and Disadvantages and Its Research Advantages and Disadvantages and Its Research Direction of Present Ironmaking Processes ZHOU Yu sheng,QIAN Hui,ZHANG You ping,LI Zhao yi,FAN Jian feng Baosteel Research Institute, Baoshan Iron and Steel Co., Ltd., Shanghai 201900, ChinaNPTEL :: Metallurgy and Material Science Lecture 54: Coal Based DR Processes (continued) Download: 55: Lecture 55: Gas based DR Processes: Download: 56: Lecture 56: Gas based DR Processes (continued) Download: 57: Lecture 57: Smelting Reduction (SR) Processes: Download: 58: Lecture 58: Smelting Reduction (SR) Processes (continued) Download: 59: Lecture 59: Ironmaking

COREX Process, FINEX Process, and Coal-Based HYL Process are very promising alternative emerging ironmaking technologies because they are already commercialized, but they have very low adoption rate in the steel industry worldwide.Performance Evaluation of an Ironmaking System with In the ironmaking process, sintered ore, coke, and solvent are charged from the top of the furnace, hot air is blown in from the tuyere at the lower part of the blast furnace, and fuels such as oil, coal, or natural gas are injected. Oxygen burns with coke at high temperatures. Carbon monoxide is produced and flows upward through the blast furnace.M.N.
