Introduction of furnace:
1.Outer housing:
welded by profile steel and steel sheet,
thickness of steel sheet is 6mm.
the brusque adopts composite structure, light refractory brick, insulation tiles and high-quality siliceous aluminous fiber cotton.
2.Heating element: the iron chrome resistance belt, which is quick heating and long lifetime etc.
3. Inner container:
stainless steel material1Cr18Ni9Ti,
thickness s = 6mm,
corrugated shape,
formed by splicing and welding,
flange is made of s=35mm steel sheet.
Cooling groove is made of stainless steel.
4. Coil base:
s =35mm steel sheet.
Coaming deflector and loading baseboard is made of A3 material, thickness 30mm.
Sealing ring is made of thermostability silicone material.
furnace bottom is equipped with lampblack-discharged device.
5. Circulating fan:
Adopt the technology of special kind dynamo plant in Harbin,
37/11kw double-speed motor;
fan blade and motor shaft material is Cr25Ni20 heat-resisting steel,
wind leaf diameter: Φ 800mm.
6. Cold- blast air cover:
the cover is made of s = 3mm steel,
blowback cooling,
internal sprinklers match outside quick couplers of water pipe,
wind and water cooling is automatic and can meet the technological requirements.
7. Electrical control system: divided into two divided control.
The way of temperature control is PID (phase shifting) trigger, and temperature control instrument adopts intelligent programmable degree 30 section. Recording instrument is paperless. And it can supply checkable records and storage the real-time historical data and process curve scheduled time by print users. Silicon controlled module is made of imported components, and others are brand-name products. The system is controlled by alarm display and chain safeguard measures. Furnace is equipped with temperature landmark inside which can guarantee the process requirements.
