Coreless induction furnaces have been used in the ferrous industry for over 50 years and are now one of the most popular means of melting and holding
Developments of Steelmaking Processes. The earliest known production of steel are pieces of ironware excavated from an archaeological site in Anatolia and are nearly 4,000 years old, dating from 1800 BCE (before common era). Horace identified steel weapons like the falcata in the Iberian Peninsula, while Noric steel was used by the Roman army. The reputation of ‘Seric iron’ of South India
If the strong magnetic field is applied to the crushed slag, precipitated calcium-phosphate solution phase can be separated from Fe t O matrix phase due to the large difference of each magnetic property. It has also been indicated by the Waste Input-Output model that the phosphorus recovery from steelmaking slag by the new process proposed in

Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar
May 26, 2018· In the iron manufacturing process, the content of phosphorus (P) in the raw materials is relatively low but is concentrated into molten iron and then removed nearly completely into steelmaking slag. Hence, steelmaking can be viewed as a P enrichment process and generates slag which has a potential to serve as a secondary resource of P. The

Abstract. To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to stone size distribution of magnetic iron (M-Fe) in the slag. Enhancement of Iron Recovery from Steelmaking Slag Fines
In the absence of an external source of magnetic field, the atoms get spontaneously partitioned into magnetic domains, about 10 micrometers across, such that the atoms in each domain have parallel spins, but different domains have other orientations. Thus a macroscopic piece of iron will have a nearly zero overall magnetic field.
