ALARC-Jet  [ Return towards  ACI Tools  ]

ALARC-Jet is a specially designed supersonic nozzle generating a focused stream of oxygen that maintains its supersonic velocity for more that 2 meters without using a flame shroud.

ALARC-Jet provides a supersonic stream – typically Mach 2 to Mach 2.5 velocity – capable of cutting, melting and refining from a distance of up to 2 meters from the bath

This allows to generate the benefits of conventional sidewall flame-shrouded injectors without the need for gaseous fuel, thus reducing the operational cost of EAF operations where predominate flat bath conditions eliminate the need for a burner function.
The ALARC-Jet nozzle is best adapted for Flat Bath operations such as:

* Large Proportion of DRI/HBI
* Continuous Charged Furnaces
* High Proportion of Hot Metal

ALARC-Jet is mounted in a water cooled copper panel that is equipped with a carbon injector located close to the slag line to provide superior carbon injection efficiency. 

Process control solutions include PLC and HMI programming for fully automated injection of oxygen and carbon
