Preheating

Ideal application for many strip processing lines The most requested application is for increased production. An increase of up to 30% is typical and can be achieved in a very short heating length prior to a furnace. Several thousand kilowatts can be installed in a single heating coil. Heating prior to pickling has many advantages. Operating costs can be substantially reduced due to several factors, such as: Lower acid concentration and less usage Lower vapor content in the atmosphere Lower acid concentration in the waste Lower water treatment costs Ultra rapid anneal is an application of preheating prior to a silicon steel decarburizing furnace. Heating to 770°C (1420°F) is typical and results in superior silicon steel electrical properties.
