World premiere: First commissioning of new type of mould ...
This new type of process reduces the "bulging" effect of the strand on the mould level at high speeds much more effectively than by simply controlling the mould level via the steel flow into the mould. For the first time ever, it is now possible to compensate mould level fluctuations with higher frequencies. New type of patented mould level control
Mini Steel Mills - MIGA
Mini Steel Mills Industry Description and Practices Mini steel mills normally use the electric arc furnace (EAF) to produce steel from returned steel, scrap, and direct reduced iron. EAF is a batch process with a cycle time of about two to three hours. Since the process uses scrap metal instead of molten iron, coke making or iron

Case Study: Improving Production Planning in Steel ...
planning of a flat steel plant. Pull Production, Mixed Model Production, elimination of waste, and creating flow are among the lean manufacturing principles that were applied in this case. The results show more than 40% reduction in work in process and cycle time, reduction in cycle time variability, and less chaos. This case shows that it is
Basics of Continuous Casting of Steel - Steel casting process
The whole process is controlled to ensure there is smooth flow of molten steel through tundish. Further, the impurities and slag are filtered in tundish before they move into the mold. The entrance of the mold is filled with inert gases to prevent reaction of molten steel with the gases in the environment like oxygen.
IRON AND STEEL
2. Generalized Process Flow Diagram A general flow diagram for the production of raw steel from iron ore is presented in Exhibit 2. In general, the process involves (1) beneficiation of the iron ore, (2) either direct-reduction or reduction in an iron blast furnace, (3) processing in steelmaking furnaces, and (4) casting. Ironmaking
Infrastructure - Visakhapatnam Steel Plant
Steel is made in steel melting shop in the refractory lined vessels called LD Converters by blowing oxygen through the hot metal bath. While iron making is a reduction process, steel making is an oxidation process. The oxygen reacts with impurities like carbon, silicon, phosphorous, sulphur etc. present in hot metal to produce steel.
The Hot Rolling Process - California Steel
finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".
Cold Rolling – Process Overview - Matmatch
The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900 °C, greater than its recrystallisation temperature. This allows steel sheets to be made in larger, thicker sizes, ideal for the manufacture of railway rails, large beams, or girders. Hot rolling vs. cold rolling
