These are a range of high quality carbon-bonded silicon carbide crucibles manufactured using the latest roller-forming technique and are designed to cater for an array of non-ferrous melting applications.
Please turn over for detailed range of shapes & sizes.
These crucibles are used for melting, holding& melt/holding of aluminium alloys in electric resistance & gas fired furnaces.
620 C - 900 C
These come in green color. Product model numbers are suffixed with letter E. E.g. BX401E
Extremely high oxidation resistance resulting in superior energy efficiency
These are Morgan’s premium quality crucibles developed for applications in fuel(oil,gas,coal) fired melting of aluminium, copper, z inc oxide & their a l loys. Himelt crucibles provide enhanced performance in those applications wheremore arduous service conditions exist.
Excel crucibles are colored dark red & utilize the code X. eg. AX 800

Each time the crucible is heated up after a cooling down phase, it should be heated following the procedure laid down for the firstinstallation. However, the drying time of 2 hours can be omitted. Should the Silicon Carbide or Clay Graphite crucible not be used for a long period, it will be necessary to eliminate moisture, which may have been absorbed from slag. In this case, the crucible should be heated up to a temperature of 200°C (392°F). After reaching this temperature, further heating should be continued as per the first installation.
The above recommendations refer to the use of new crucibles in existing furnaces. When installing a new Silicon Carbide crucible into a new furnace, the heating and drying instructions of the furnace manufacturer should be followed. If the furnace manufacturer prescribes a longer heating cycle (or curve), this procedure should be carried out without the crucible. It is essential that the crucible is installed in an absolutely dry furnace.
Note:
Pre-heating cycle
The crucible after installation in the furnace should be heated up slowly to a temperature of 200°C (392°F) over a period of 2 hours, to eliminate any moisture that may be present.
Next, these crucibles should be heated up to a temperature of 950°C (1742°F) on full power, if possible.
Silicon Carbide crucibles used in a melting operation can be continuously heated up on full power until working temperature is reached. The crucible is then ready to be charged with care.
When using Silicon Carbide crucibles for holding, the temperature of 950°C (1742°F) should be reached and held for approximately one hour. This ensures even melting of the glaze with the additional antioxidation coating, which is essential to achieve the maximum possible crucible life.
For holding crucibles this procedure should be carried out periodically, but always before starting up again after a prolonged cool down period. This helps to compensate for the negative effects of low holding temperatures.
The following practices should be observed in order to achieve the maximum possible crucible life. If any further advice or information is required please contact our sales or technical staff.
