Induction heating furnaces are employed for vacuum distillation process to recover and consolidate heavy metals after electrorefining operation. Induction heating furnaces of suitable heating rates are required to be developed for this purpose. Hence it is planned to set up a mock-up induction furnace which will simulate the conditions to be realized in actual induction heated vacuum distillati...

Powderous crystalline materials of the composition Fe3−xMnxC have been prepared by first synthesizing Fe3C via mechanical alloying in a planetary mill followed by the addition of elemental manganese and arc-plasma melting or via the classic ceramic route in an electric furnace. The milling time for the synthesis of Fe3C was significantly reduced through adjusting the parameters of the planetary...

Recently, titanium-tantalum alloys have been studied as implant materials for dental and orthopedic surgery. However, titanium and tantalum are difficult to mix by common arc melting and induction melting, because of their high melting point and the marked difference between their densities (Ti: 1,680 degrees C, 4.5 g/cm3, Ta: 2,990 degrees C, 16.6 g/cm3). Thus, the Cold Crucible Levitation Mel...

The new silicide NbPdSi was prepared by melting the elements in an arc-furnace. Well-shaped single crystals were obtained by annealing the sample in an induction furnace. The structure of NbPdSi has been studied by X-ray powder and single crystal diffractometer data: TiNiSi type, Pnma, Z = 4, a= 643.0(1), b= 376.7(1), c= 744.4(2) pm, wR2= 0.0330, 346 F2 values, and 20 variables. The palladium a...

State-of-the-art melting of tantalum and tantalum alloys has relied on electron beam (EB) or vacuum arc remelting (VAR) for commercial ingot production. Plasma arc melting (PAM) provides an alternative for melting tantalum that contains very high levels of interstitials where other melting techniques can not be applied. Previous work in this area centered on plasma arc melt quality and final in...

The following issues are considered: the role of hot heel in scrap melting by electric arcs in the furnace freeboard; advantages and disadvantages of furnaces with a single charging and those with a telescoping shell; Specifics of furnace scrap hampering its heating by burners. The possibilities of using different types of burners for scrap heating are analyzed including stationary burners and ...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

The melting temperatures have been determined for a wide range of substances as a function of pressure. In the present work, Teflon (polytetrafluoroethylene) was investigated up to 30 kb and the decomposition temperatures, and the melting temperatures of silver chloride and iodine were determined up to 30 kb and 20 kb, respectively. General Technique. -The pressure was generated with a piston-c...
