2. Furnace specification:

The furnace is cylinder shape design, which looks beautiful and elegant. The furnace shell is steel welded structure, and the high quality silicate aluminum refractory acupuncture blankets is used to form the furnace lining, double side heat preservation. This kind blanket is processed strong compression by mold, ensuring the heat preservation effect. Between the furnace lining and cover, there is heat insulation and preservation material, play a role in isolation. The heating elements adopt 0Cr25Al5 flat resistance tape, hanging on lining wall, fixed by high aluminum refractory bolt, total up and down two heating blocks. Furnace bottom adopts high strength light weight refractory brick and high alumina brick castable structure. The furnace cover is steel plate structure, furnace lining inserted. There is suspension loop on the cover, convenient for cover operation. This furnace is whole fiber structure, this kind structure is with small heat capacity, little heat lose, fast temperature rising and cooling and perfect heat insulation performance. All these heat preservation structure make the excellent furnace temperature uniformity ±5ºC. This kind furnace is very popular because of it excellent performance: high heat transferring and capacity, low power consumption, long service life and simple maintenance.

3. Furnace composition

3.1 Furnace body:

The furnace shell is 6mm steel plate welded, formed steel construction strengthening. The bottom adopts special shaped steel brick, accurate fitted with the furnace shell, extending the service life. The shell surface processes polishing and derusting treatment, printed undercoat and finishing coat.

3.2 Furnace pot:

The pot body material adopts 321stainless steel, with 8mm thickness, corrugated shape body. The bottom adopts ellipsoidal head, 12mm thickness, no oxidation corrosion and heat resistance of 1100ºC.
