Application breakdown
High-temperature Cement Board L23
Used in the potroom in strip form between pot covers and cathode frames and in pad or plate forms between the anode support, the control gear and the superstructure.
Firefly FF700
Firefly FF700 millboard is a popular choice for many sealing requirements including syphon tube gaskets in molten metal transfer equipment.
Firefly FF700 millboard provides the insulating layer between the crucible and its hot face refractory lining, reducing heat losses and thereby maintaining melt temperature longer. It is also used underneath the pots. FF700 possesses the necessary strength to be used as a permanent former when casting concrete.
Inside the electrolysis pot, Firefly FF700 millboard shields the anodes in order to exclude alumina whilst gas heating takes place during start-up. Once the operating temperature is reached the millboard becomes a sacrificial component in the pot.
RF1000
RF1000 grade products are used as the insulation in crucibles, transport ladles and launder systems ensuring cost-effective maintenance of liquid metal temperature for long periods of time.
CS1150 pouring nozzles
CS1150 pouring nozzles have replaced conventional calcium silicate and cast iron tubes for flow control of liquid aluminium.
Nitrasil
Nitrasil greatly extends the working life of graphite shafts used in rotary degassing equipment.
Nitrasil can be easily formed into extrusion nozzles.
Nitrasil thermocouple sheaths offer alternatives to Syalon and silicon carbide.
Nitrasil is hard and wear-resistant. Its use as seats and pistons in valving operations ensures trouble-free performance.
Materials
Cement Boards
Tenmat’s high-temperature cement board grades are designed to operate at elevated temperatures offering, primarily, thermal insulation performance, but also outstanding electrical properties.
Nitrasil engineering ceramics
Nitrasil is an engineering ceramic with superb inert properties that allow applications in numerous high-temperature and non-ferrous molten metal environments
