Ppt About Iron Making Process

The Midrex process uses a shaft furnace to convert iron oxide pellets or lumps into direct reduced iron (DRI) through the removal of oxygen using a reducing gas composed of hydrogen and carbon monoxide produced from natural gas. Natural gas and recycled offgas are converted to hydrogen and carbon monoxide in a reformer and this reducing gas is ...

FINEX process is a commercial proven alternative iron making process for the production of hot metal (HM) in addition to the blast furnace (BF) process route, consisting of BF, sinter plant, and coke oven. This process is based on the direct use of non-coking coal. The FINEX process can directly use iron ore fines without any kind of agglomeration.

Recrystallization is a process where deformed grains in a material are replaced by a new set of undeformed grains that form and grow until the original grains are completely replaced. This process typically reduces the material's strength and hardness while increasing its ductility. ... IRON AND STEEL MAKING - Download as a PDF or view online ...

12. 2.5 BASIC OXYGEN FURNACE (BOF) The pig iron is added and the limestone also added to reduce the impurities and to form the slags. Steel making process by dumping recycled steel scrap into the Basic Oxygen Furnace(BOF) and adding hot iron sparks, the high purity oxygen to blown oxygen furnace into the mix at supersonic speeds and then …

The Production of Iron First the ore is graded and crushed and the fine particles sintered. Sintering is the process of converting fine particles into a continuous mass Iron ore powder is compacted and then heated to a temperature below …

It consists of a reduction shaft and a melter-gasifier that work in countercurrent to reduce iron ore to hot metal. The Corex process offers advantages over traditional blast furnaces such as using coal and lump ore without sintering, producing hot metal with suitable quality for all steel applications, and having outstanding environmental ...

3. Decision Making Process • According to Baker.. "efficient decision-making involves a series of steps that require the input of information at different stages of the process, as well as a process for feedback". • In Psychology.. decision-making is regarded as the cognitive process resulting in the selection of a belief or a course of action among several alternative …

3. Introduction To conserve the fines it has become essential to agglomerate the fines to a desired size which can be charged in the blast furnace. Many types of agglomerating processes are available where sintering is techno - economically viable. Resulted in installation of sinter plants. Sintering can be defined as agglomeration of fines into a porous mass by …

4. CHARGING PROCESS In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls …

The document describes the process of forming iron and steel using a blast furnace. It involves the following key steps: 1. Sinter is added to the top of the blast furnace. Air is blasted into the bottom to fuel reactions that melt the iron out of the sinter. 2. Molten iron collects at the bottom of the furnace and is tapped out periodically.

The process description. The most innovative feature of the Corex process is the separation of the iron reduction and smelting operations into two separate reactors, namely reduction shaft and melter-gasifier. In the two-stage …
