The efficiency of the application of high-emissivity coatings on the furnace walls in steam cracking technology can only be evaluated on the asis of a description of radiative heat transfer distinguishing between the frequency bands. To this end, a non-grey gas radiation model based on he exponential wide band model (EWBM) has been developed and applied in the context of three-dimensional CFD s...

The purpose of this study was to increase the effectiveness slag cleaning in cast iron smelting process using an induction furnace. This resulted calculation terminal velocity emerging surface furnace based on Stokes' Law approach for each that appears during process. For casting, three samples were taken fastest time very light slag, slag’s heaviest and extreme comparison. results sample are t...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

The results of the study working conditions in aluminum casting shops worksites are presented. these studies showed that there exceedance permissible limits for noise, vibration, content harmful substances environment, intensity infrared (thermal) radiation and air temperature. There is effect electromagnetic on workers during service induction furnaces. In addition, main production factors inc...

Abstract Induction furnace slag (IFS) and quarry dust (QD) were reported as good materials in making ordinary concrete. Studies not done on utilizing IFS QD constituents of high-performance-self-compacting-concrete (HPSCC). This study aims at assessing the effects induction strength durability high-performance self-compacting Strength tests including compressive, flexural, split tensile, reboun...

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...

Abstract Porosity in aluminum alloys is a great concern to the casting and automotive industry. In this publication, porosity formation air-melted vacuum induction melted (VIM) was studied compared understand its effect on microstructure mechanical properties of Al-7Si alloys. were cast at 700°C 900°C muffle furnace VIM furnace. Microstructural results show that refined eutectic silicon with sa...

Ethylene cracking furnace system is the heart of ethylene production. It can process different raw materials in the pipe group of each furnace and can produce the main chemical products like ethylene, propylene and ethane. In the real world ethylene plant, there are two operation modes in the furnace system, one has a backup furnace in the system and the other is with all the furnaces available...
