Crucible Furnaces

Crucible Furnace Options

• Gas-fired units offer faster melting rates than electric units and are suitable for higher melting point alloys
• Electric furnaces offer excellent metal quality and silent operation.
• Excellent SCR temperature control for high turndown ratios and simple to maintain, package burners.
• Electric furnaces use multiple elements wired in parallel to avoid shut down if one element lost.
• Suitable for Al alloys, Zn alloys, Mg alloys and lead.
• Flexible melting and holding capacities depending on metal and alloys.
• Available for Electric, Natural Gas.
• Available in stationary or tilting versions for optimum temperature control.
• Smallest installation footprint allows for close installation at the point of use.
• Flexible melting and holding capacities depending on metal and alloys.

Output Methods

Hand ladle, auto ladle, dosing/pump or direct-pour methods are available.

Lids are available in several types and styles:

– All furnaces are delivered as standard with a manual lift off lid.
– Split “Butterfly” lid:  allowing 1/2, 1/3 or 2/3 of crucible-opening access.
– Full-hinged cover/lid.
– Lift-and-swing-aside cover.
– Dome cover: allowing for ingot charging above the crucible top.

Covers are available as manual or pneumatically operated versions depending on furnace size and configuration.

Additional Considerations:

– Type of charge material and mix.
– Volume demand of molten metal every hour.
– Transfer rates and ladle size.
– Holding temperature requirements.
– Alloy to be melted, held and cast; aluminum, zinc, magnesium.
– Degassing requirements prior to casting.
– Central melt or “point-of-use” melting.
– Working hours: 8×5 days shift up to 24/7 continuous.
– Burners and power-connection-points orientation and placement.
– Emergency run-out port orientation and placement.
– Manual or pneumatically-operated functions.
