Centralized ladle preheating system. Final report, March 1982-February 1984
Ladle preheating in metals production is an energy-intensive process and is usually done inefficiently. A successful ladle preheating system for large-scale applications (ladle of 50 to 500 tons capacity) has been developed. This system uses a heat exchanger and sealed heating thus minimizing losses. Because of equipment costs, identical systems cannot be economically scaled down for ladles under 50 tons. However it is possible to centralize some functions of a multiple heating station thus reducing capital costs. A single heat exchanger, combustion air blower, and control subsystem can be shared by several heaters. The scope of this project is to produce such a design. The development of this technology will allow foundries and small-scale steel mills to reduce their energy cost for ladle preheating. It may also convince operators to implement an energy saving gas fired system where no heating was previously being used.
