Protection, degasing tubes and stalk – proper use instructions:

  • Store in dry atmosphere before use
  • Preheat before heating the cold furnace
  • Gradually heat up/ cool down material – avoid abrupt cooling and heating
  • Handle with care
  • Keep under regular maintenance in order to enhance lifetime

CERAL offers a whole range of technologies & designs upon specific demand, and provides relevant usage instructions.

Protection tubes, degasing stalk for the foundry industry

Protection tube

protection tube B

Main applications

CERAL silicon nitride ceramic has the best thermal conductivity when used for aluminium melting applications. Even though there can be a temperature difference between the tube and the aluminium solution in some harsh environments, the heater protection tube will work stably. Regarding its lifetime, it can be used for many years with the correct operation environment and regular maintenance.

Stalk for low pressure die casting

Protection tube for low pressure die casting

Main applications

Low pressure die casting protection tube

CERAL silicon nitride ceramic stalk has an excellent corrosion resistance for LPDC applications. It has remarkable heat-retaining properties so that the heat loss is reduced to a minimum.

The stalk can be used for many years if kept under regular maintenance.

Stopper pipe

stopper pipe

Main applications

stopper pipe low pressure die casting

CERAL silicon nitride ceramic has high density and abrasion resistance; it is the most suitable material for low-pressure die-casting.

The stopper pipe has the most favorable properties: toughness, non-wetting with excellent design precision

The stopper pipe can be used for many years if kept under regular maintenance.

Non-wetting property is very important when used in low-pressure die casting applications.

Degassing pipe and rotor

Main applications

degassing tube manufacturer die casting

CERAL silicon nitride ceramic has high density and abrasion resistance, it is the most suitable material used for degassing pipe and rotor shaft.

CERAL silicon nitride rotor shaft shows an exceptional corrosion and oxidation resistance compared with other products. It ensures high hydrogen removal efficiency.

The rotor shaft can be used for many years if kept under regular maintenance.

The efficiency of degassing varies according to the rotor shape and other conditions.

We sell the most suitable rotor according to one’s environment.
