The effectiveness of rotary degassing on the defect formation and mechanical properties final casting aluminium alloy EN AC 46000 was investigated, along with its impact energy consumption in furnace. In melt preparation prior to casting, molten metal is usually transported from melting furnace as a cleaning procedure. Under conditions this specific study, negligible degradation observed cast c...

This paper deals with high energy consuming induction holding furnace. The improved version of coil design along additional electrical interlocks and alarm, modified hydraulic controls, strengthening mechanical structures saving proposals at furnace fume extraction system ensures trouble free operation hence continuity production all the planned plant operational days. project involves in purch...

The environmental resistance of pure iron was evaluated by an oxygen and hydrogen sensor installed after oxidation furnace. amount introduced precisely controlled the pump at front stage furnace, reaction with analyzed. Thus, when supplied, a between occurred; however, supplied not sufficient, hydrogen-vapor environment created, accelerated. Conversely, excessive, became oxygen–steam environmen...

This paper presents an experimental investigation of the fabrication Cu–multi-walled carbon nanotube (MWCNT) nanocomposites prepared via electroless chemical deposition technique followed by powder metallurgy (PM) method. To enhance dispersion and wettability MWCNTs with a Cu matrix, were given coating Ag nanoparticles. 0.4, 0.8, 1.2 wt.% first coated 5 nanoparticles, then mechanically milled n...

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...

In this work, the effects of scale on thermal behavior of the slab in a walking-beam type reheating furnace is studied by considering scale formation and growth in a furnace environment. Also, mathematical heat transfer model to predict the thermal radiation in a complex shaped reheating furnace with slab and skid buttons is developed with combined nongray WSGGM and blocked-off solution procedu...
