Preheating is burned by mixing with the gas from the EAF. This enables to eliminate an airpollution after dust collector.

By provision of preheating fan, existing fume treatment plant can employ the scrap pre‐heater without modification.

As the system is fully automatically operated, this system does not require additionalworker.EAF operation will not be interrupted even though the preheating system run into atrouble.

Recycling method of preheating system can be controlled separately from dust collectorsystem.

Proper adjustment of the preheating temperature prevents the scrap bucket from beingdeformed.
