controlled atmosphere furnace with N2 muffle furnace, 1200 1400 1700 degree muffle electric digital programmable vacuum atmosphere furnace for firing ceramics
HIQ series atmosphere furnace is a special furnace designed for products that require atmosphere protection. The furnace chamber can be filled with inert gas, nitrogen, also can be pumped out with vacuum, so that the workpiece will not produce oxidative decarburization. It is suitable for atmosphere protection sintering and atmosphere reduction in industrial and mining enterprises. The atmosphere furnace is equipped with various valves, flow meters, pressure gauges, etc. as required. The furnace body has good airtightness, the vacuum degree can reach -0.1MPa, the operation is simple, and the loading and unloading is convenient.

Heating Elements |
· 6 sets of Mo coils heating elements are built in, and replaceable · The heating element of Mo coil is consumable parts which should be ordered separately if extra sets are required. · Heating element can be replaced by MsSi2 to run furnace under oxygen and air up to 1700°C. · Warning: Mo heating element can not be used under air or oxygen at the temperature > 300°C |
||
|
Temperature Control |
· Temperature controller is included. · Proportional-integral-derivative control (PID control) and auto-tune function · 40 segments programmed with ramping, cooling and dwelling steps · Built-in over-temperature alarm and thermocouple failure alarm · +/- 1 ºC temperature control accuracy · Default DB9 PC communication port |
||
|
Gas Flow Control and Vacuum Valve |
· Two large flow meters (N2: 0~3.5L/min, H2: 0~3.5L/min) are installed on the front panel of the furnace. · One for purging Inert gas prior to introducing H2 gas · One for controlling H2 gas flow · One heavy duty vacuum pump built in bottom furnace. |
||
|
H2 Gas Burning Control System |
· An ignition device already installed to incinerate flowing gas and detect burner temperature to ensure H2 burner is in working condition. If H2 does not burn properly, the controller will shut down the H2 gas delivery valve immediately. |
||
|
Water Cooling |
A 16L/min recirculating water chiller is installed in bottom of furnace for cooling furnace sealing flange. |
||
|
Application Notes |
· Please EXERCISE EXTREME CAUTION. H2 gas is highly flammable and explosive. H2 ignites at a temperature of 400°C, an explosion could occur when the hydrogen content reaches 4.0%-74. 2% in the air, please strictly follow the rules below to for safety operation. · Inert gas MUST be used to purge the furnace chamber to eliminate all the air before introducing the H2 gas. · The pressure inside the chamber should ALWAYS be controlled at 0.01-0.02 Mpa above the standard atmospheric pressure during the entire heating process, otherwise, the oxygen in the air may backflow into the furnace chamber and cause the explosion in the worst case scenario. · Pressure over 0.02Mpa or below -0.05Mpa (Relative Pressure) is strictly prohibited. · ALWAYS place the furnace in a room with a fume hood and a hydrogen detector installed. · Good ventilation is necessary for the room in which place the furnace · Exhausting Hydrogen gas in the room is forbidden. · Must be used under inert gas or hydrogen gas environment · For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 10 °C /min. · Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating. |
