A System for Recycling Rock Mineral Wool Process Residues Back through a Cupola Melting Furnace
ثبت نشده
چکیده
The production process for rock mineral wool insulation products generates a number of residue streams with different physical characteristics. Together these add up to a significant proportion of the raw materials input to the process. Previously, recycling of the residue had not been viable because of the abrasive nature of the different materials streams and specific processing constraints and it had been disposed of to landfill. Much of the material is low density, bulky and costly to send to landfill.

Intelligent Control of Cupola Melting
The cupola is a furnace used for melting steel scrap, cast iron scrap, and ferroalloys to produce cast iron. Its main energy source is coal coke. It is one of the oldest methods of producing cast iron, and it remains the dominate method because of its simplicity and low fuel cost. Cupolas range in size from 18 inches to 13 feet in diameter, and can produce up to 100 tons per hour of cast iron. ...
متن کاملPreparation of Slag Wool by Integrated Waste-Heat Recovery and Resource Recycling of Molten Blast Furnace Slags: From Fundamental to Industrial Application
The present paper investigated the process of the slag wool fabrication using high temperature blast furnace (BF) slag modified by coal ash (CA). The liquidus temperature and viscosity of the slag system with different mass ratios of BF slag and CA were measured through an inner cylinder rotation method. The approximate mass ratio used to fabricate the slag wool was therefore determined and sla...

This paper deals with a novel interactive approach of Artificial Neural Network (ANN) as an optimization tool for optimizing process parameters of rotary furnace. This approach solves a very challenging problem in the area of rotary furnace i. e. selection of optimal process parameters for producing homogenous quality castings. Rotary furnace involves several critical parameters like flame temp...
متن کاملThermodynamic simulation on mineralogical composition of CaO–SiO2–Al2O3–MgO quaternary slag system
It is necessary to elucidate the crystallization thermodynamic of mineralogical phases during the cooling process of the molten BFS with different chemical composition, because the high-melting point mineral phase maybe crystallized during the fiber forming and thereafter cooling process. Thermodynamic calculation software FactSage6.4 and the hot remelting experiments were performed to explore ...
متن کاملA Study on Physical Factors Stimulating the Semicircular Canals Receptors (Cupola)
SUMMARY Although sciences and techniques have been significantly developed, many patients are still suffering from diagnostic and therapeutic problems of vestibular system, specially vertigo. Perhaps, these problems are not solved yet mostly because the neurophysiology of vestibular system and the stimulation mechanisms of the receptors are not known. This difficulty, intum, causes some a mbig...
