The smelting, forging, rolling and drawing parameters are determined this study. By using nitrogen oxygen analyzer, direct reading spectrometer, OEM, electronic probe universal material testing machine, chemical composition, gas content, inclusions, internal microstructure, m...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

New method of observation and diagnosis of inverter-fed induction motor drives is developed and tested. Unsymmetrical conditions concerning the machine impedances or valves operation are reflected in the spectrum of the current space-phasor. The spectrum of the space-phasor was estimated with the help of the Wigner-Ville distribution (WVD) and its time-frequency representation with excellent ti...

In this research (using induction furnace process) nodular iron with three different percentages of copper (residual, 0.5% and 1,2%) was obtained. Chemical analysis was performed by mass spectrometry and microstructures were characterized by Optical Microscopy (ASTM E3) and Scanning Electron Microscopy (SEM). The study of mechanical behavior was carried out in a mechanical test machine (ASTM E8...

BaIrIn2 was synthesized from the elements in a sealed tantalum tube in an induction furnace. The indide was investigated by powder and single crystal X-ray data: Cmcm, a = 443.3(1), b = 1151.3(2), c = 806.0(1) pm, wR2 = 0.0471, 352 F2 values, and 16 variable parameters. The iridium and indium atoms build up two-dimensional [IrIn2]2− polyanions (279 – 281 pm Ir–In and 310 — 314 pm In–In) which a...

An end-point temperature prediction model based on RBF neural network is developed to reduce the measuring cost and improve the measuring accuracy in a vacuum induction furnace. It can give reliable predictions of tapping time and temperature of molten steel in the first-round prediction. And the prediction accuracy can be improved by the error correction in the secondround prediction. 120 set ...

Ferrochrome is the major chromium source for stainless steel production, and submerged-arc furnaces (SAF) are most commonly utilised to smelt chromite ores into ferrochrome by using suitable carbonaceous reductants such as coke. Because of the complexity of feed structure and electrical-thermal-chemical interactions, there exist large gradients and wide distributions of temperature, mineralogy ...

Ni-Al-Mo based alloys can be used as materials for high temperature applications. They prepared by various techniques such an electron beam zone melting, which allows us to obtain the with a directionally solidified structure and unique properties. A plasma-melted Ni-Mo master alloy was preparation of experimental alloys. were melted in induction furnace then cast centrifugally form bars. These...
