Abstract:
The disclosure relates to a lance tube (1) having a central through-hole extending along a longitudinal axis (A). The lance tube has a double-layered end portion (2) having an annular outer layer (4) of a high temperature corrosion resistant first alloy and an annular inner layer (5) of a second alloy, wherein the inner layer and the outer layer are mechanically interlocked, and wherein a metallic bond has been formed between the inner layer and the outer layer by means of hot working, and a mono-layered main portion (3) of the second alloy. The lance tube is suitable for use in a lime kiln.
