Abstract. Technological knowledge of the use metals is inseparable from human in processing pyrotechnics fire as a power high temperature processes for producing objects. The used smelting and casting melting furnaces. Metal furnace heat production device, which to purify metal, this case iron. This paper aims determine development ferrous metal technology Indonesia with library research method...

Introduction: Protecting the vital organs in radiation therapy is one of the most important issues. Cerrobend alloy, the most common material used as the shield, is melted several times and used for different patients. In this study changes in attenuation coefficient of cerrobend due to melting was investigated.   Materials and Methods: In melting furnace, ...

The manufacture of optical fibers typically involves taking a solid glass cylinder (a blank or preform), heating it up to melting temperature by feeding it through a cylindrical furnace (the drawing tower), and drawing the molten blank from the other end of the furnace at high speed (tens of meters per second). Since the drawing speed is much faster than the feeding speed (by a factor of at lea...

The nickeland iron-aluminide alloys are an important class of materials because of their unique resistance to oxidizing, carburizing, and sulfidizing environments at high temperatures. They also provide an interesting combination of high-temperature strength and wear resistance. Many applications have been identified for these materials including: furnace fixtures, heating elements, pumps, hydr...

On the basis of formulated mathematical model for study electromagnetic processes in a two-phase (two-inductor) induction channel furnace, electrical losses metal frameworks furnace were calculated vari-ous options their sectioning. The influence phase angle between voltages feeding inductors fur-nace on distribution specific and integral frames is determined. Practical recommendations re-ducin...
