Second, the furnace structure:

The furnace body is designed in a cylindrical shape, and the outer casing is welded by 5 PCT A3 steel plate. The internal thermal insulation material of the main body is made of ceramic fiber insulation board, heat exchanger, lightweight insulation brick, high alumina refractory brick and silicon carbide crucible. The flaming cast and the bottom of the furnace are made of refractory castable.

Third, the combustion system:

High-pressure fans, electronic control valves, mixing mechanisms, solenoid valves, proportional valves, pressure reducing valves, pressure gauges, gas control parts and other necessary combustion systems are combined in separate bodies.

Fourth, the temperature adjustment method

1. Temperature regulation of aluminum soup

A set of CA TYPE thermocouples is set in the , for easy temperature measurement. According to the need to set the temperature, the burner proportional combustion for automatic temperature control.

2. Temperature regulator and thermocouple

The temperature regulator is digital display (proportional balance type), thermocouple stainless steel protection tube is used Ф20 *L500mm
