A 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 کاملHybrid Intelligent Control for Optimal Operation of Shaft Furnace Process
The extensively used shaft furnace in the ore concentration industry is an important facility that turns the weak-magnetic low-grade hematite ore into strong-magnetic one. During the operation of the shaft furnace roasting process, the optimal control objective is to control the technique indices, namely the magnetic tube recovery ratio (MTRR) that represents the quality, the efficiency, and th...
متن کاملNeural Modeling as a Tool to Support Blast Furnace Ironmaking
This paper describes the development of a hybrid model based on artificial neural network and its industrial application to the ironmaking at Companhia Siderúrgica Nacional (CSN -Volta Redonda/Brazil). The Iron Blast Furnace is highly complex process subject to oscillations in raw material characteristics. A precise model is essential to adjust © 2002 charging and blow conditions to match produ...
متن کاملParallel Simulation of an Ash Melting Furnace
We determine the distribution of heat uxes of a furnace for burning ash via a simulation of a heat transfer problem. With paralleliza-tion of the problem this task can be done faster. Within the volume of the furnace, heat transfer is dominated by radiation, where heat conduction through the walls is important. Our mathematical model leads to a system of polynomials and the problem is reduced t...
