Major crucible melting furnaces are of steel fabricated construction using plate and rolled sections. The furnace is lined with high temperature rated refractory, backed with calcium silicate insulating board.
Standard temperature control is achieved by sensing flue gas temperature which is shown on a digital display.
Bath Temperature Control (Optional)
An immersion thermocouple in a protective sheath can be used to sense actual melt temperature. This optional extra is supplied with an LED display of set and operating temperature.

Main isolating switch
In case of accidental spill of metal or failure of crucible within the furnace an emergency plug fitted in the base would automatically dislodge, thus allowing molten metal to escape from within.
The two stage packaged type burner is complete with built in fan, flame safety controls and electric ignition. The burner, when not operating, is protected against radiant heat from refractory by a thermostat activating the fan to maintain burner internals within acceptable temperature limits.
Electric Resistance Heating
Banks of electric elements of nickel chrome alloy held in ceramic supports surround the crucible providing the necessary energy to melt the charge.
