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...

Technological procedure of extracting metals is being constantly modernised so that polluting of the basic life resources is reduced. Emissions of waste gases and particulate matter are still present in larger mining-metallurgical complexes. Mining-metallurgical complex Bor (RTB) exploits sulphide copper ores, thus emitting acid sulphur gases and suspended particles with high content of Cu, Zn,...

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...

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...

The estimation of metallurgical parameters of flotation process from froth visual features is the ultimate goal of a machine vision based control system. In this study, a batch flotation system was operated under different process conditions and metallurgical parameters and froth image data were determined simultaneously. Algorithms have been developed for measuring textural and physical froth ...

To attempt to optimize the anomalous phenomena that today go under the label "cold fusion" the experimentalist should be aware of the many aspects of the behavior of hydrogen in metals and of its entry into and egress from metals. This paper discusses the equilibrium characteristics of the isotopes of hydrogen in metals. The first section discusses the thermodynamics of the terminal solutions o...

Abstract This article presents the oldest iron smelting furnaces of Xiongnu Empire period in central Mongolia and argues that a significant center existed at site Baga Nariĭn Am. Five four installations were excavated, with total 26 further identified through SQUID magnetometry. In combination review data on production contemporary Mongolia, Transbaikal region, Tuva, Minusinsk Basin Altai, we a...

Metallurgical accounting in the mineral processing industry transforms accumulated process data, including flow rates and assays, into a coherent information format. This is used to rapidly provide production reporting and key performance indications. Comprehensive and coherent data must be a component of any system expected to accomplish reconciliation in the mass-balancing process. Quality is...
