Hotface Welding

Furnace repairs at the operating temperature and without stopping production

To carry out ceramic welding during furnace operation a dry mixture (the welding material) is pumped into the furnace.

Many different lance designs and sizes are available which makes it possible to work on damaged areas in the furnace that are normally difficult to reach, such as the crown, port necks, burner arches and doghouse arches. The various welding materials available are described on our webpage under “welding materials and compositions“.
