The furnace can be operated by relatively unskilled workers who charge a batch into the furnace, smelt it for a given time period (4–6 h) and tap the furnace bullion and slag. The slag utilized by most of the rotary furnaces is FeS–Na 2 S matte. Iron is added as a reducing agent along with coke and produces an oxide slag-matte combination.

Aug 27, 2020· With the induction furnace, the slag is cold and the temperature of the slag is maintained by molten steel. With the arc furnace, the slag is hot and the furnace itself keeps it hot. The arc furnace can complete the dephosphorization by the furnace slag, which also allows for sufficient expansion for the deoxidation process. This is why the ability of the arc furnace to de-phosphorize is better than the induction furnace.
The Coreless Induction Furnace is considered by many to be the most versatile melting unit available for the foundry industry. The demands placed on the refractory lining vary and are often very complex, bringing very different sets of circumstances that can affect the …
Understanding these conditions, Inductotherm Group equipment—furnaces, pouring systems, power supply units and more— are not only designed with sophisticated metallurgic controls for efficient thermal processing, but with a rugged reliability that is known the world over.
same as those of reverberatory furnaces. The induction smelting and refining process is designed to produce aluminum alloys with increased strength and hardness by blending aluminum and hardening agents in an electric induction furnace. The process steps include charging scrap, melting, adding and blending the hardening agent,
Oct 26, 2011· Steel is poured into a ladle and transferred to a secondary steelmaking station for further refining. The molten slag is carried to a slag-processing unit with ladles or slag pot carriers [1–3, 5]. In electric-arc furnaces, up to 300 tons of steel can be manufactured per cycle (a cycle takes one to three hours to complete).
Dec 11, 1991· An induction furnace for use in processing industrial wastes of metals to melt said industrial wastes as a slag on a metal bath, said induction furnace comprising: a crucible which has an internal space, a crucible center axis, and an axial symmetrical configuration with respect to said crucible center axis and which has a crucible bottom ...

The Induction Melting Furnace is advanced melting equipment for gold, silver, copper, berylliumand other nonferrous metal melting. This furnace adopts big power medium frequency inductionmelting way, fast heating speed, electromagnetic stirring function to …
Installation Modernize your melt system with custom installation and construction services from EMSCO. EMSCO works closely with automatic pouring system manufacturers for ferrous and nonferrous applications to fill in the gap between the time when you order new equipment and the time when you begin operating the new equipment.
The primary components of iron and steel slag are limestone (CaO) and silica (SiO 2). Other components of blast furnace slag include alumina (Alsub>2 O 3) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO). In the case of steelmaking slag, the slag contains metal elements (such as iron) in oxide form, however …
VIM 100 – 4000 Vacuum Induction Melting and Casting Furnaces for Charge Weights from 1 to 30 tons. In 1928 the first industrial scale vacuum induction melting and casting furnace was engineered and manufactured by ALD''s parent company and then commissioned in Hanau, Germany near today''s ALD headquarters.
Nov 26, 2018· Most of the steel mills in Bangladesh use induction furnace which produces large quantities of slags that have very little use except land filling. Therefore, feasibility of using this slag is examined in concrete with recycled aggregate, which is another waste product that is generated due to removal of old structures.
De-slagging is the process by which the slag layer above the steel is removed from the furnace. This process is important for removing impurities from the molten material. The furnace is tilted towards the slag door for slag removal. Phosphorus is transferred to the slag, during the early stage of the heating while the temperature is relatively low.

Most ESR furnaces today are started "cold" with dry prefused slag. Consarc can also provide a slag melting furnace with the ESR system that gives "hot" (liquid) slag start capability. This is most useful in situations where humidity and moisture are concerns, as well as in locations where sourcing of prefused slag is problematic.
Abstract. Nickel-base, cobalt-base and iron-base alloys melted in vacuuminduction furnaces are desulfurized to very low sulfur levels by reacting them with slag-forming mixtures comprising high purity lime and a fluxing agent, under reducing conditions, so as to form a slag no hotter than the melt.
control systems commonly used to control particulate emissions from electric arc and induction furnaces are bag filters, cyclones, and venturi scrubbers. The capture efficiencies of the collection systems are presented in Tables 12.13-1 and 12.13-2. Usually, induction furnaces are uncontrolled. Molten steel is tapped from a furnace into a ladle.

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.
developed synthetic slag is validated with experimental works in the induction furnace and empirical models and it has been discussed in subsequent section. 2.
into the Furnace either manually or from the Scrap lifted with an EOT /DRI crane. Power is put on through the power cables to induction coil which starts melting the charge. The Metallic charge melts to form liquid steel. As soon as the Liquid bath achieves a Temperature of around 1650°C, it is tapped into Steel ladle for further processing.
