The low thermal inertia designed solder pot furnace
enables rapid initial heat up to 330 C and quick cool down from the maximum temperature, thus minimizing time wasted in temperature adjustments.
Here, a silicon carbide crucible rests inside a gas-fired, 100 lb capacity "pot furnace
But due to the high cost of running the old pot furnaces
and replacing them, coupled with the cost of labour, many of the larger local companies have been forced into closure or, like Royal Doulton, restructured.
Larger or special sizes and tilting crucible and pot furnaces
as well as alternate-energy models for melting brass, gold or silver can be built to order.
The direct reduction process deploys a range of equipment, including pot furnaces
, reverberatory furnaces, regenerative furnaces, shaft furnaces, retort furnaces, stationary or rotary kilns, etc.
