The price of iron scrap increased aligned with the price of its upstream steel products, which include iron ore, iron ore concentrate, iron pellet, sponge iron and iron briquettes, and, of course, due to rising steel prices in the global market. As we know, access to iron scrap is somewhat difficult given the limited supply. Its price is also high.
Sep 15, 2019· The iron made in a blast furnace is an alloy containing about 90–95 percent iron, 3–4 percent carbon, and traces of other elements such as silicon, manganese, and phosphorus, depending on the ore used. Pig iron is much harder than 100 percent pure iron, but still too weak for most everyday purposes. Cast iron

Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 909 areas of 500–1600 cm2 g1. The concentrate must therefore be reground in order to prepare suitable pellet feed. High pressure grinding roll (HPGR) and ball mill are the most widely used
The temperature of the pig iron melt rises from 1250 °C to over 1600 °C. For this reason, approx. 20 % iron scrap is added for cooling in order to protect the converter lined with stones from excessive temperatures. Iron ore or sponge iron (from the direct reduced iron process) can .
Steel is simply lowcarbon iron. As such, the steel manufacturing process begins by smelting iron ore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace. This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal.
A process for recovering iron/steel from scrap mill scales and fines is disclosed. A process in accordance with embodiments of the present invention comprises mixing mill scales and fines with coke or other carbon containing fines and sealing the mixture in a container. The container is charged into a cupola or blast furnace, where the components react to form molten iron/steel.

metallic iron such as directreduced iron (DRI) or hot metal can also be used in the EAF route. The main coproducts produced during iron and crude steel production are slags (90% by mass), dusts and sludges. Process gases, for example, from the coke oven, BF or BOF are also important coproducts. However, this fact sheet will mainly focus
Apr 22, 2017· HYL process for direct reduction of iron ore was the fruition of research efforts begun by Hojalata y, (later known as Hylsa), at the beginning of the 1950s. After the initial evaluation of the concept, it was decided to install a process using a tunnel furnace and several runs were undertaken.
