Crucible furnace are used for melting of metals and alloys, and also for storage of all kinds of melts. Normally, crucible furnaces are available in fixed and tipping positions. Fixed crucible furnaces are suitable for melting metal and store it in a molten state, depending on the fill in special forms. Crucible furnaces are often used to pour metal from the furnace because of its inclination around its axis.

In crucible furnaces heating is performed using coils made of fechral wire which is wound on an alumina tube, and for this purpose may be used silicon carbide. Built-in heater core in the crucible furnace provides the opportunity to achieve higher temperature conditions during metals melting.

Management of crucible furnaces can be carried out through a dedicated electronic control unit, which makes regulations and temperature control. In order to reduce the inertia of the thermocouple control channel it is necessary to install ceramic straw with open junction.

Crucible furnace with a maximum temperature of 900-1200 degrees is used for melting of tin, zinc, and their alloys. Heating in these furnaces is carried out by coils made of fechral wire.Construction of crucible furnace, in which the maximum temperature is equal to 1400 degrees, is used for smelting copper and various copper alloys. In order to heat must use the n-shaped silicon carbide heater, which is sure to set horizontally.

If you produce a high-temperature alloys using crucible furnaces special crucibles and disilicide, ie special heating elements should be applied. There is an opportunity to reload the crucible during melting without opening the lid. In comparison with other models of furnaces design of this furnace is very economical, because it uses a new high-performance lining materials made of high-temperature heaters that have heating elements with increased resource.
