Abstract
An annealing line for a steel strip, a device for use in such an annealing line and a method for annealing a steel strip. The annealing line including a connecting chamber connecting a first heating section and a second heating section, wherein one or more devices, located in the connecting chamber, are arranged on one or both sides of the steel strip for oxidising the steel strip using an oxidising gas mixture, each device having a body including an internal chamber and one or more openings to project the oxidising gas mixture onto the surface of the steel strip.

An annealing line for a steel strip comprising a connecting chamber connecting a first heating section and a second heating section,
- wherein one or more devices, located in the connecting chamber, are arranged on one or both sides of the steel strip for oxidising the steel strip using an oxidising gas mixture, each device having a body comprising an internal chamber and one or more openings to project the oxidising gas mixture onto the surface of the steel strip,
- wherein the internal chamber is divided into three or more compartments,
- wherein three said compartments of the internal chamber comprises respectively a central compartment and a first pair of outer compartments, each outer compartment is positioned adjacent to the central compartment, wherein the device comprises inlet means for providing the oxidising gas mixture, a first inlet means coupled to a first conduit for providing the oxidising gas mixture to the central compartment,
- the device further comprises a second inlet means coupled to a second conduit for providing the oxidising gas mixture to the first pair of outer compartments.
