Fives’ New High-Flux Magnetic Induction Technology
05/25/2015 - Fives, a global industrial engineering group that designs and supplies process technologies to various industries, has developed a new generation of reheating furnace inductors with reduced operational costs and minimized NOx emissions.
An induction heating process that provides very rapid heating and allows heat to be generated inside the object itself is a very attractive solution for steel producers. Such a heating solution mostly applies to high capacity hot-rolling mills that require high power and density.
A high-flux inductor should be installed at the furnace discharge outlet to enable the furnace to operate at a lower temperature while the billet is being quickly reheated at the constant temperature before it is delivered to the mill. Therefore, the residence time at high temperature is drastically diminished; and the scale quantity is reduced.
Fives has developed a new high-flux magnetic induction technology CELES CELINE with high-intensity magnetic fields being generated by multilayer coiling. The power is injected into the product up to 4 to 6 MW/m2, which is 6 times more than the capability of conventional inductors.
This technology has been developed for long products – CELES CELINE LP, and flat products – CELES CELINE FP, and is mainly used for continuous casting lines before roughing mills or finishing mill stands, or at reheating furnaces or in thermal profile correction machinery at rolling lines.
CELES CELINE LP technology eliminates the temperature difference between a head and a tail of the billet and reduces skid marks thus improving production quality. Due to lower operating temperature of the furnace, the technology allows for the reduction of maintenance costs, i.e. extended lifetime of refractory and unloading rolls.
The combination of CELES CELINE LP and a gas reheating furnace for a standard 360,000 t/y mill provides the following advantages:
- Metal loss: 66% less
- Production cost: 40% less
- NOx emissions: 42% less.
Most significantly, this induction heating technology drastically cuts electricity costs as the electric efficiency is measured at 85% above the Curie point in comparison to the standard 65%. CELES CELINE LP has a very compact footprint so it can easily be integrated into existing lines. The equipment generates virtually no magnetic field in the environment close to the inductor, which has emissions ratings consistently below European standards.
As a sustainable solution, CELES CELINE technology increases metallurgical properties of the steel grade and reduces greenhouse gas emissions while meeting quality and performance criteria of steel makers.
Fives provides highly efficient technical solutions for the steel industry in the carbon, stainless and silicon sectors. Fives' global offer includes thermal, mechanical, induction equipment, surface treatment, rolling and strip processing for flat, tube & pipe and long products. Fives also offers a wide range of expert services, including metallurgical assistance, auditing, technical consulting, downstream client support, upgrade and retrofit capabilities. Fives’ technologies achieve ultimate product quality, enhanced flexibility, reduced OPEX and minimized environmental impact.
