Advantages of process of manufacturing iron

12.5 iron and steel productionin the basic oxygen process (bop), molten iron from a blast furnace and iron scrap are refined in a furnace by lancing (or injecting) highpurity oxygen. the input material is typically 70 percentsponge iron production process arij tradingsponge iron production process discussed herein are selected from known methods of which the references are available and referable. we look at the 4 different methods of producing sponge iron midrex process. hyl process (4th generation) or energiron. sl / rn process. tunnel furnace process.steel manufacture steelconstruction.infoas with all largescale manufacturing processes, the production or iron and steel generates byproducts. on average the production of 1 tonne of steel results in 200 kg (eaf) to 400 kg (bf/bof) of byproducts. the main byproducts produced during iron and crude steel production are slags (90%), dusts and sludges.iron processing iron making britannicairon making the primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.process for production of iron patent ca2119448c pubchemca2119448c chemical patent summary.how clothes iron is made material, history, used, partscertain components, like the spring for the thermostat, cord, plug, and related connections are usually outsourced by iron companies. the manufacturing process first, each subassembly of the iron is produced, most often on separate, automated production lines. then the iron is assembled. sole platecasting production process and lead time iron foundryshell ming process is a type of sand casting process, which is usually used for making iron castings, but now, some steel foundries are trying to use it to produce steel castings too. before batch production, the foundries need about 30 to 45 days to make the metal patterns and samples.
