SPETHERM exothermic powder and covering fluxesCharacteristics: Under the designation SPETHERM, we offer a range of compounds, from insulating to highly exothermic, for most alloys.
The individual grades are adapted to the special requirements in G-GX, GJL, GJS, light and heavy metal casting.
The shelf life, if stored in dry conditions, is 6 months.
Heating compounds particularly recommended for heavy metal casting:
- SPETHERM AHZ
- SPETHERM AHZ- 4
- SPETHERM AH 5
- SPETHERM AP 39
Other SPETHERM compounds available on request.
Special slag binder for GJL, GJS, G-GX and heavy metalCharacteristics: High-quality granular material for reliable binding and collection of liquid, viscous and dry slags. The slag crust in casting and transfer ladles and in induction furnaces is prevented and thus slag inclusions in castings are avoided.
SPEDOX makes it easier to remove the slag from the bath surface before casting or improved and reliable holding back of the slags during casting.
SPEDOX is neutral with regard to the molten metal and is also free from constituents harmful to health and is thus also not subject to mandatory labelling.
SPEDOX is suitable for grey cast iron, ductile cast iron, heavy metal casting and similar high melting point alloys.
