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 ferrous materials.
Iron is extracted from iron ore in (i) blast furnace as pig iron and (ii) DRI / Sponge iron produced by solid state reduction of iron ore. ... Fig 1. Tapping Molten Steel from Induction Furnace. The popular process routes for manufacturing alloy steel : ... Double slag process is practiced for removing P2O5 and CaS from slag.
Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals. The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process .
Steel - Steel - Electric-arc steelmaking: About one-quarter of the world's steel is produced by the electric-arc method, which uses high-current electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
composition is adjusted to meet product specifications; and slag removal and molding the molten metal. 12.10.2.2.1 Furnace Operations - The 3 most common furnaces used in the iron foundry industry are cupolas, electric arc, and electric induction furnaces. The cupola is the major type of furnace used in the iron foundry industry.

Electroslag remelting (ESR), also known as electro-flux remelting, is a process of remelting and refining steel and other alloys for mission-critical applications in aircraft, thermal power stations, nuclear power plants, military technology, etc.. The electroslag remelting (ESR) process is used to remelt and refine steels and various super-alloys, resulting in high-quality ingots.
The process involves skimming the slag, removing it through a door and dumping into a bucket as well as manipulating the scrap in the furnace to complete the melt process. These operations were done manually with the operator standing next to the open furnace door utilizing a long handle ladle.
The induction process thereby places particular requirements on the refractory lining, which are fulfilled by spinel forming dry masses on MgO and Al 2O 3 basis. The induction furnace compared to the electric arc furnace Table 1 compares the main features of electric arc and induction furnaces for melting steel in mini-mills. Accord -

Nowadays slag is considered an essential component in iron and steelmaking processes, due to its direct contact with the metal baths, refractories and the environment of the equipment.
x and slag is produced compared to the oxygen process [5]. The relative, absolute growth in ... the direct reduction process, in which prepared iron ore pellets are reduced from oxygen in their solid state by a heat ... frequency induction furnace for steelmaking met with little or no success [10].
Process for melting cast iron borings comprising continuously charging dried borings into a coreless induction furnace operated within controlled metal levels to achieve adequate stirring of the molten metal in the furnace, drawing incoming borings beneath the meniscus of the molten metal surface, controlling the dissolved oxygen content of the molten metal to ensure formation of carbon oxide ...
melting furnaces, pressure pour furnaces and magnesium treatment vessels with minimal to no adverse effects on refractory linings. Slag Formation: The formation of slag in the melting of ferrous metals in the foundry is inevitable. The composition of slag varies with the type of melting process used and the type of iron or steel being melted.
Control of Slag and Insoluble Build-up in Melting Furnaces ... Up in a Coreless Induction Furnace The areas of slag deposits are at a much lower temperature than the center of the furnace walls. ... and in the using flow-through process. Slag buildup in ductile iron treatment ladles is a very common problem at ductile iron foundries.
Sep 29, 2009· Not yet.I am not sure whether induction furnace slag can be used or not for making slag wool. I have seen that many of the Indian the induction furnace operators have not even bothered to get the chemical analysis of the slag. They are spending money to .

0.2 to 0.4 tons of slag, and 2.5 to 3.5 tons of blast furnace gas containing up to 100 pounds (lb) of dust. The molten iron and slag are removed, or cast, from the furnace periodically. The casting process begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of the hearth.
3.2 Copper induction melting furnace. Induction copper melting furnace is mainly divided into (line-frequence cored induction furnace and medium frequency induction furnace). The line-frequence cored induction furnace can melt and heat the metal, the heating is evenly with no loss, which is convenient for adjusting the molten metal composition .
