Slopping of Slag in Basic Oxygen Furnace

Slopping of Slag in Basic Oxygen Furnace Steelmaking in basic oxygen furnace (BOF) is a batch process in which steel is made from liquid iron. The concentration of elements such as carbon (C), manganese (Mn), and phosphorous (P) have an impact on the steel quality. For the steel to be cast, it needs to be …

Process Control of Technological Processes

Process Control of Technological Processes Technological processes consist of handling, working, refining, combining, and manipulating materials and fluids to profitably produce end products. These processes can be precise, demanding, and potentially hazardous processes. Small changes in a process can have a large impact on the end result. Variations in proportions, temperature, flow, turbulence, and many …

Refractory Lining of the Electric Arc Furnace

Refractory Lining of the Electric Arc Furnace Refractories are those materials which withstand high temperature without a significant change in chemical or physical properties. Refractory materials are very important to the electric arc furnace (EAF) operation as they allow the containment of the liquid steel in the furnace hearth without damaging the furnace structure. The …

Preparation and Charging of Blast Furnace Burden

Preparation and Charging of Blast Furnace Burden Blast furnace (BF), except at its hearth, is basically a passage for gases and burden particles which move in the counter-current directions in the BF. The basic requirement for stable operation of the BF is to maintain in the furnace a moving layer of burden which does not …

Understanding Ironmaking in Blast Furnace and Dissection studies in Japan

Understanding Ironmaking in Blast Furnace and Dissection studies in Japan The blast furnace (BF) ironmaking is the most viable means of producing hot metal (HM) mainly due to its well established and proven performance, flexible raw material usage, and high thermal energy conservation capability. There are no definitive dates available for the inception of BF …

Production and Processing of Armour Steel

Production and Processing of Armour Steel In the present day environment, there are accelerated efforts to deliver lightweight armour technologies which can defeat armour-piercing (AP) projectiles at reduced areal weights. While many of these efforts involve the application of lower density metals such as aluminum and titanium, the selection of steel alloys continues to be …
