Experimental control of a cupola furnace [PDF]
Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998 We present some final results from a research project focused on introducing automatic control to the operation of cupola iron furnaces. The main aim of this research is to improve the operational efficiency and performance of the cupola furnace. Experimental data are used to calibrate the model, which is taken as a first-order multivariable system ...

Archives of Metallurgy and Materials, 2018 Blast furnace and cupola furnace are furnace aggregates used for pig iron and cast iron production. Both furnace aggregates work on very similar principles: they use coke as the fuel, charge goes from the top to down, the gases flow against it, etc. Their construction is very similar (cupola furnace is usually much smaller) and the structures of pig ...

Mathematical model for the combustion phenomena in a cupola furnace
Revista Facultad de Ingeniería Universidad de Antioquia, 2006 Se presenta un modelo matemático que describe los fenómenos de combustión en un horno de cubilote. La construcción del modelo se realizó con base en las reacciones heterogéneas coque-gas más importantes; es decir, la reacción de combustión, la gasificación por CO2 y la gasificación por vapor de agua.

Final report on process modeling of cupola furnaces [PDF]
, 1990 This report describes the first phase of the AFS/DOE program on mathematical modeling of cupola behavior, covering the period May 19, 1989 to July 19, 1990. The objective of the program is to develop a comprehensive mathematical model of the cupola furnace for on-line and off-line process control and optimization.

Cupola Furnace Design and Fabrication for Industrial Development [PDF]
International Journal Of Scientific Advances, 2021 The Cupola Furnace Capacity of 450 kilograms per hour was designed and fabricated using locally sourced raw materials which include pig irons, crop ends and foundry shop returns, and ferroalloys for the production of quality cast iron which depends on the customer’s demand.

Optimal choice of cupola furnace nominal operating point [PDF]
Proceedings of Thirtieth Southeastern Symposium on System Theory, 2002 One of the main goals in the operation of a cupola furnace is to keep the molten iron properties within prescribed bounds while maintaining the most economical operation for the cupola. We present a procedure to obtain the nominal values for the manipulated process variables.

Fine and Ultrafine Emission Dynamics from a Ferrous Foundry Cupola Furnace [PDF]
Journal of the Air & Waste Management Association, 2010 Aerosol size distributions from ferrous foundry cupola furnaces vary depending on semicontinuous process dynamics, time along the tap-to-tap cycle, dilution ratio, and the physical and chemical nature of the charge and fuel. All of these factors result in a highly time-dependent emission of particulate matter (PM) 2.5 pm or less in aerodynamic diameter

Numerical Analysis of Reactions in a Cupola Melting Furnace
ISIJ International, 2004 Composition variations of metal and slag in a cupola melting process were investigated by a reaction model for gas/liquid iron/coke and slag/liquid iron systems. A significant amount of alloy elements is lost due to the gas oxidation in furnace shaft. Carbon in metals is determined by gas oxidation and carbon pickup from coke in the shaft.

The Impact of Iron Casting in Cupola Furnaces on the Environment
MM 2023The production of iron castings in cupola furnaces is a significant industrial process that has a notable impact on the environment. This paper examines and describes the environmental impact of this process, specifically focusing on the generation, characterization, and utilization of waste materials through data analysis and collection. Approximately

Application of Computer Support for Design of Shaft Furnaces – Cupolas
Journal of Casting & Materials Engineering, 2017 Designing a machine’s constructions and an object’s structures is one of the areas of technology design. The complexity of the structure is defined by the technology for which it is used. Following the theory of construction and mechanisms, the full characteristics of a machine or device is defined by its shape and operating parameters.
