steel making process pdf
Be able to understand basic layout of blast furnace, steelmaking shop and continuous casting process. Pig iron is manufactured from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. Direct Reduction Technique 3. Vanadium recovery Before conversion into steel, vanadium is recovered from the molten iron. Engineering 11 1. producing iron from iron ore Methods in iron Making Process 1. Step 2 Steel making The steel making process is shown in Figure 2. INTRODUCTION TO STEEL DESIGN AND CONSTRUCTION 8 II. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. I. Smelting Reduction Technologies Coke-oven-Sinter-BF route used by integrated steel plants that produce steel from iron ore. Connection Design 18 4. The present study explores the steel-making process, which can improve the product quality. phenomena (heat, mass and momentum) to the process steps in Iron and Steelmaking as practiced in integrated steel plants. The process of mining low -grade iron ore, or taconite, requires massive resources. The production of steel in an EAF is a batch process. Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. Engineering Calculations 22 B. AIST has collaborated with Purdue University Northwest’s Center for Innovation Through Visualization and Simulation to create a unique, interactive experience of the steel manufacturing process. Iron And Steel Manufacturing Process. Coke-oven-Sinter-BF route 2. See also Coke Manufacturing. Secondary Member Design 17 3. Interactive Steel Manufacturing Process AIST’s Making, Shaping and Treating of Steel ® Wheel. Four steps: Iron Making Process. This is done firstly because of the value of the vanadium rich slag produced (15% vanadium as V2O5) and secondly because a high vanadium content can make the steel too hard. To develop computational and mathematical abilities to be applied for process design and control. Creating steel from low-grade iron ore requires a long process of mining, crushing, separating, concentrating, mixing, pelletizing, and shipping. Stages Advanced Bill of Material 24 2. Detailing 23 1. Detail Drawings 28 4. Other Steel Making Processes; Smelting Reduction Technologies; Coke Ovens-Sinter-BF-BOF Route; Some of the technological options for converting iron ore to steel products is schematically shown below.Hot metal and crude steel process are also inter linked … steel plants. Erection Drawings 26 3. The equipment used Main Member Design 13 2. THE STEEL PROCESS – FROM DESIGN THROUGH ERECTION 10 A. In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining.
