The main use of the crucibles and furnaces covers (also called lids) is to maintain the temperature of liquid metal. For this reason, we can find them in all the different fields in which aluminum, lead, tin, zinc and magnesium alloys are applied.
The use of an insulated crucibles and furnaces covers significantly reduce energy consumption. Ditta Musto researches the right materials that ensure lead insulation, generally supported by a metal frame.
In the case of magnesium, by regulating gas, the cover allows for bath inerting in order to protect it. The lids can be handled manually or are controlled by a pneumatic ram. The design of these furnaces and crucibles covers (also known as lids) can be adapted to any type of furnace or to customised dimensions.
