Description

Applications

Starrbide crucibles are particularly suitable for processes with frequently changing temperatures and high heating rates. Starrbide crucibles can be used for the holding of all non-ferrous alloys. They have a very high mechanical strength and a high refractoriness, making them especially suitable for melting heavy metal alloys. Additionally, they are resistant to chemical attack by fluxes. Starrbide crucibles are suitable for electric resistance heated and fuel-fired and induction furnaces. They perform well under difficult operating conditions.

As a consequence of user-related innovative developments, optimised Starrbide variants are available.

Starrbide HT / VO crucibles are particularly appropriate for melting copper and bronze alloys in furnaces with high power and high heating rates.

Starrbide U IND crucibles are suitable for medium frequency induction furnaces for melting and holding. They perform well under difficult operating conditions.

Starrbide HT / VO Typical Metal Casting Temperature 

800°C – 1400°C (1472°F – 2552°F).

Starrbide U / U IND Typical Metal Casting Temperature

700°C – 1000°C (1292°F – 1832°F).

Performance Characteristics

• Outstanding thermal shock resistance.
• Very good thermal conductivity.
• High oxidation resistance.
• Very high mechanical strength.
• Good resistance to chemical attack.

Identification

Starrbide crucibles are coloured black and utilise the suffix C to denote the type.

Pattern Range

Starrbide crucibles are available in a wide range of sizes and shapes. Sizes can be made available with pyrometer holes to facilitate measurement of metal temperature. A wide range of pouring lips and spouts is available.

Quality

Excel and Himelt crucibles are manufactured from premium grade raw materials under an ISO 9001:2015 quality management system.
