Ceramic furnaces are used with zinc bath temperatures of up to 620 °C. The ceramic kettle ensures an almost unlimited service life without interruption.
Long-term damage to the kettle by diffusing zinc is prevented by special shaped bricks. These are installed in such a way as to create a system of cool air channels.
A sheet metal clad sectional steel construction protects the masonry by absorbing the hydrostatic pressure of the liquid zinc and also protects the ceramic material (bricks) from crackin.
The heat energy is supplied to the zinc bath either by means of a heating hood through the bath surface or via direct contact to the hot zinc with immersion burners.
