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 کاملA System for Recycling Rock Mineral Wool Process Residues Back through a Cupola Melting Furnace
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 a...
متن کاملMolecular dynamics study of melting of a bcc metal - vanadium I : mechanical melting
We present molecular dynamics simulations of the homogeneous (mechanical) melting transition of a bcc metal, vanadium. We study both the nominally perfect crystal as well as one that includes point defects. According to the Born criterion, a solid cannot be expanded above a critical volume, at which a ’rigidity catastrophe’ occurs. This catastrophe is caused by the vanishing of the elastic shea...
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...
متن کاملMelting Heat Transfer Analysis on Magnetohydrodynamics Buoyancy Convection in an Enclosure: A Numerical Study
The roll of melting heat transfer on magnetohydrodynamic natural convection in a square enclosure with heating of bottom wall is examined numerically in this article. The dimensionless governing partial differential equations are transformed into vorticity and stream function formulation and then solved using the finite difference method (FDM). The effects of thermal Rayleigh number (Ra</em...
