燒結爐Investment Casting Furnace
All the showing products were actually designed and made by TAJUNG.
|Old Model||New Model|
|With on-off control system|
No automatic control lead not combustion air cooling the furnace
|Intelligent process temperature control system |
(manually and automatic control the ratio of wind and oil)
|The Advantage of new control system|
|a. When the shell mold goes into the furnace, the ventilation door would automatically turn big and |
the oil door will automatically turn small.
b. If the temperature raised, the ventilation door and the oil door would automatically turn big.
c. If the temperature reached, the ventilation door and the oil door would automatically turn small.
d. If over temperature, fuel would be shut down automatically.
e. When the shell mold come out from the furnace, the ventilation door would automatically turn small
and the oil door would automatically turn small or shut down.
|2. Save 10 % to 30 % efficiency.|
|3. The furnace body will prolong its lifespan because of no overheating.|
|4. Automatic public security：New Air Pressure electric insert furnace, wind wheel manual and |
automatic shock-proof ventilation door control, it can prolong the lifespan of furnace body and door.
|Waste Heat Recycle|
Waste Heat recycle into
|(1) make drinking water|
(2) heat exchange to hot wind
(3) for lost was furnace
(4) produce 5℃ ice water together with injection ice water and hot
(5) Pure condensing turbine power generating
a. supply cool air for the precise cast room
b. supply cool air for the wax –lost room of precise cast
c. supply cool air for the office
d. supply cool air for dormitory
e. cool air to produce, no need “ Freon”, reduce pollution
|Waste heat recycle into|
|a. for bathing|
b. for boiler water preheating
Waste heat recycling can reduce the heat from the chimney, the temperature of exiting gas can be reduced to 150℃, the furnace body temperature can also be reduced. And it can reduce the working environment temperature to increase the work efficiency. Waste heat can recycle the steam vapor value. Each furnace can reach to 300 to 600 kg / hr. And we can have 80% of waste heat recycle efficiency.
The shell mold preheat furnace for the sintering furnace has to undertake the special characteristics:
1. Temperature control
2. Temperature rising period
3. Heat distribution
4. Energy efficiency
5. Working environment (heat penetration)
6. Success rate of casting
7. Lifespan of furnace
8. Environment protection
9. Duration of validity for maintenance
The traditional furnace body structure was composed of combustion Chamber built of fire-resistance bricks, a set of burner and a pipe installed behind the furnace. It was operated in such a poor way that truly could not possess and bring the above capabilities and function.
|3-step Automatic Temperature Control||ON-OFF Automatic Temperature Control|
|At the first ten minutes after shell mold being placed into the furnace, the combustor will not spur oil. But heat recovery air will be provided and sent continuously to prevent from producing black fume. |
The second –step: Temperature will be set 1000℃ so that shell mold can adjust temperature difference better and avoid being over-expanded.
The temperature has to reach at 1200℃ about 10 to 15 minutes before the furnace is opened for pouring.
The temperature can be adjusted and set according to the need of real situation for each time.
|When the temperature reaches to the set temperature ,it will be automatically controlled within ±20℃. |
When two combustors reach to the set temperature, one of the combustor will be automatically turned off at anytime to avoid too much temperature difference and to get heat inside the furnace equally distributed.
