Nexelia - Iron melting by supersonic oxygen injection into shaft furnaces for the metal industry

A digital energy and resources saving optimisation tool for iron melting by supersonic oxygen injection into shaft furnaces.

The Nexelia for metal melting solution is dedicated to the metals industry and especially foundries, where so called shaft furnaces are used to melt metallic scraps together with coke to produce cast iron. Shaft furnaces are often using oxygen injection to enhance the melting performances and increase capacity. BoostAL Digital technology consists of an oxygen injection system coupled with an advanced control system to operate shaft furnaces more efficiently. Especially by increasing operating flexibility of the furnace, improving temperature homogeneity inside the furnace and finally by reducing maintenance/control operations linked to oxygen lances.
