- providing at least one injection device through the inner wall of the shaft furnace and through a cooling stave, the injection device being configured to inject protective material into the shaft furnace against the cooling staves;
- and
- injecting on demand the protective material into the shaft furnace through the at least one injection device, in such a manner that the protective material builds up to form a protection wall between the interior of the shaft furnace and the cooling staves lining the furnace wall,
- wherein the hot face of the cooling stave comprises a profile with ribs and grooves, wherein the step of providing the injection device through the cooling stave comprises the step of passing the injection device through a rib or a groove of the profile of the hot face of the cooling stave.
