depending on the raw material basis. Essentially all FeCr is produced in submerged arc furnaces‚ while the role of competitive technologies like DC is limited. In all furnaces fluxes are used to optimize the slag composition. Vital characteristics are smelting point‚ electric conductivity and viscosity. The main components of FeCr slag are SiO2‚ Al2O3 and MgO. Additionally it consists of Cr-‚ Fe-oxides and CaO. Granulated slag and/or classified slag products are produced depending on the production process

Process chart of TSL‚ INDIA was first addressed. So‚ it all starts with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained

Iron Making Technology A thousand years before the age of empires in Rome and Greece‚ the Iron Age was ushered into the world with the clank and clatter of the blacksmith’s anvil. The transition from the Bronze Age occurred at different times in different spots on the globe‚ but when and where it did‚ the distinctive dark metal brought with it significant changes to daily life in ancient society‚ from the way people grew crops to the way they fought wars. Iron has remained an essential element

these societies‚ it remains an extremely expensive metal‚ although it is anything but rare‚ why? It is impossible to know for sure why iron is so valuable‚ but many scholars believe that early iron production was not intentional‚ but a byproduct of smelting other metals (Forbes 1958:9). There is evidence that the Egyptians obtained gold dust which was rich in magnetite sand. While not as dense as gold‚ magnetite is considerably denser than other common sand minerals‚ and is often found with gold.

here. I understand the practical viewpoint of this move but this scenario seems to limit the capability of the country to produce from its own resources. Nonetheless‚ I admire the company’s vision to address this concern by merging with the Calaca smelting plant. I believe that Philippines can also produce our own steel from iron ores. The automation is the plant is impressive but I recommend that the operators’ level of education match their current

How A Steel Mill Works The principal consumables employed in steel production are iron ore‚ coal‚ scrap metal and electrical energy. The importance of each of these consumables depends upon the technological processes adopted at each mill. In a classic integrated mill‚ coal and iron ore are the main consumables. In semi-integrated mills‚ scrap iron is the mainstay. An integrated mill comprises four basic operations – reduction‚ refining‚ solidification‚ and rolling – to convert iron ore
