MUFFLE FURNACE

The GWL-XL series high-temperature furnace with a temperature range of 800-1200 degrees is shown in the figure, featuring an integrated design of the control system 

and the furnace chamber. The furnace lining is made of vacuum-formed high-purity alumina lightweight materials.

Silicon carbide rods are adopted as heating elements; It is a specialized equipment specially developed for laboratories in colleges and universities,

 research institutes and industrial and mining enterprises to conduct sintering, melting, analysis and production of ceramics, metallurgy, electronics, glass, 

chemical engineering, machinery, refractory materials, new material development, special materials, building materials, metals, non-metals and other chemical materials.

.

The furnace chamber material is all made of vacuum-formed high-purity alumina lightweight material. It features a high operating temperature,

 low heat storage capacity, resistance to sudden heating and cooling, and excellent heat preservation performance (the energy-saving effect is over 60% of 

that of the old-fashioned electric furnace). The structure is reasonable, with double-layer furnace sleeves inside and out, and air-cooled heat dissipation, 

which can greatly shorten the test period.

Model: GWL-1200Xl

Power supply: AC 380V 50Hz

Power: 80KW

Furnace chamber dimensions: Length × width × height: 1000×1000×1000 mm

Control range: 80 to 1200 degrees

Temperature measurement element: Thermocouple classification number K, temperature measurement range 0-1320 degrees

Number of temperature measurement points: 1 temperature measurement point

Number of heating zones: 1 zone for temperature control

The installation position of the heating element: Vertically installed on both sides of the furnace chamber

Temperature control accuracy: ±1 degree (no overshoot phenomenon)

Furnace temperature uniformity: ±10°C (depending on the size of the furnace chamber)

Heating rate: Adjustable. The fastest heating rate is 15 degrees per minute (15 degrees /min), and the slowest is 1 degree per hour (1 degree /h).

Heating element: Silicon carbide rod, a non-metallic high-temperature electric heating element made of high-purity A-sic as raw material

Furnace body: Processed by CNC machine tools, it has the advantages of anti-oxidation, corrosion resistance, high-temperature resistance and easy cleaning

Furnace body structure: It adopts an air-cooled double-layer furnace body structure to prevent high-temperature oxidation of the conductive sheets of the

 heating elements and ensure a good working environment
