The metal is melted to about 12501310C in the cupola and is then conveyed to the induction furnace. Hot gases present are sucked by pressure. Coke balls are used to fill the furnace with the metal. Secondary melting and maintaining composition: This process is carried on using a Channel type press pour furnace. 12

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,

The limitation of core type induction furnace can be eliminated by use of vertical type furnace called Ajax-wyatt Furnace. The furnace is narrow V-shaped. V – shaped tendency of the molten metal is to get itself accumulated at the bottom and this helps at least a small amount of charge to be present for the secondary circuit to be completed.

The development of Induction Furnaces starts as far back as Michael Faraday, who discovered the principle of electromagnetic induction. However it was not until the late 1870's when De Ferranti, in Europe began experiments on Induction furnaces. In 1890,Edward Allen Colby patented an induction furnace for melting metals.

Refining in Induction Furnace is not as intensive or effective as in Electric Arc Furnace (EAF). 2. Life of Refractory lining is low as compared to EAF. 3. Removal of S & P is limited, so selection of charges with less impurity is required. Induction Furnaces are classified generally into two categories:

Induction Generator. Just like a DC Machine, a same induction machine can be used as an induction motor as well as an induction generator, without any internal modifications. Induction generators are also called as asynchronous generators. In an induction motor, the rotor rotates because of slip (i.e. relative velocity between the rotating magnetic field and the rotor).

Furnaces are batch process tools with the ability to process more than 100 wafers at a time. Figure 2.14(a) gives the schematics of a vertical furnace, and Fig. 2.14(b) shows a horizontal furnace. Due to a smaller footprint and better contamination control, only vertical furnaces are used in advanced 200- and 300-mm IC fabs.

The induction heating process can be completed on the manufacturing floor, next to the cold or hot forming machine, instead of sending batches of parts to a remote furnace area or subcontractor. For example, a brazing or soldering process which previously required a time-consuming, off-line batch heating approach can now be replaced with a ...

A. PVD in an induction furnace Physical vapor deposition (PVD) was performed in a quartz tube (30 cm length, 4 cm in diameter) vertically inserted into an induction coil. The elemental tellurium powder (0.05 g) was placed at the bottom of the quartz tube, on a graphite rod. Heating of the tellurium source

• The furnace can be equipped on both sides with 4 up to 8 burner ports (per side) depending on furnace size. • The profile of heating (fuel distribution among the burners located along the sidewalls) determines location and size of the hot spot area (primary fining zone) in the glass melt.

Casting furnaces. 1. CASTING FURNACES Melting is an equally important parameter for obtaining a quality castings. A number of furnaces can be used for melting the metal, to be used, to make a metal casting. The choice of furnace depends on the type of metal to be melted. 2.

A typical prior pit furnace apparatus is shown and described in U.S. Pat. No. 2,264,740, issued to Brown on Dec. 2, 1941 for a Melting and Holding Furnace. With the intrusion of the crucible into the melting chamber, the volume of the melting chamber is reduced, thus requiring a larger furnace for a given volume of melt, with a

Induction heating is based on electromagnetic laws. The overall system can be approximated by an electric transformer, where the primary is the copper coil into the induction cooker and the secondary the bottom layer of the pot (see Figure 4 and Figure 5). The heat generated is
