Salamander Crucibles - Original

APPLICATIONS
SALAMANDER SUPER crucibles are used to provide consistent performance in fuel-fired furnaces and medium / high frequency induction furnaces.
The smaller sizes are typically used to melt precious metals, while larger sizes can be used for some ferrous alloys such as grey iron as well as to melt non-ferrous alloys.

TYPICAL METAL CASTING TEMPERATURE
850 - 1600°C (1562 - 2912°F)

Lining Clay Crucibles

--------------------

Clay crucibles need to be treated before use for extended life. Fill about 25% of the crucible with a mix of 50% borax and boric acid. Heat the crucible gradually until the mixture melts. Carefully tilt the crucible so as to coat the entire inner surface.

Than pour the excess away and allow the crucible to cool to room temperature.

PERFORMANCE CHARACTERISTICS
• Clean melting
• Good thermal conductivity
• Good resistance to chemical corrosion
• High refractorines

PREHEATING / FIRST USE
FUEL-FIRED FURNACES: A new crucible should be pre-heated empty in order to minimise the temperature gradient across the crucible wall.

If the furnace refractories have been repaired or if
there is a risk of the crucible having absorbed some moisture,
then the furnace should initially be heated slowly up to circa 200ºC and held at this temperature until all moisture has been driven off.
