| 5 | Control zone | 1 zone, independent control |
| 6 | effective working size | 1200×1200×1200mm(L×W×H) |
| 7 | Heating element connection | Y |
| 8 | temperature uniformity | ±8℃ |
| | temperature mesaurement accuracy | ±1℃ |
| 10 | Empty furnace power consumption | ≤18% |
| 11 | Temperature control method | SCR, PID regulator Shimaden Japan programmable temperature controller with 485 communication interface work with 10.1 inch touch screen. The touch screen can record historical data, store processes, export USB flash drives, take screenshots, and other functions, with an over temperature alarm. |
| 12 | furnace surface temperature rise | ＜45℃ |
| 13 | Heating element | 0Cr25AL25 (strip) |
| 14 | Bogie face plate | CrMnN, 30mm thickness |
| 15 | Loading method | Manual or forklift loading into the furnace |
| 16 | Axial flow fan | The hot air circulation system of this equipment mainly consists of 1 set 2.2KW water-cooled axial flow fans. The heat emitted by the heating element is evenly blown into the effective working area by the circulating fan. The material of the fan and shaft is Cr25Ni20. In order to ensure the normal use of the bearings, the cooling method is water cooling. |
| 17 | Furnace door opening method | Manual side opening, spiral compression |
| 18 | Furnace lining | high temperature refractory fiber structure |
3.Structural Introduction
The JRX3-90-9 box type heat treat furnace is mainly comprised of furnace body, lining, furnace door
and door compression system, heating element and fixed device, and temperature control system.
3.1 furnace body, 1 set
3.2 lining
3.3 furnace door and compression system
3.4 load-bearing furnace bottom
The load-bearing electric heat treatment furnace bottom is comprised of
refractory bricklaying body and heat resistant face plate CrMnN.
bricklaying body: The bogie is built with a heavy combination of high alumina refractory bricks,
light refractory bricks, and heat preservation bricks. The impacted parts and weight bearing area
are bricked especially with heavy type high aluminum refractory bricks. There is also free space
left for the refractory lining expansion when heated.
The bogie face plate is made of CrMnN with total thickness of 30mm. The maximum
temperature is ≤ 950 ℃, which can be used for a long time without deformation and cracking.
3.5 heating element
heating element: The 0Cr25AL5 resistance spiral-shape alloy resistance strips are mounted
in 2 side walls, back wall, furnace door and bogie bottom.
3.6 electrical control system, 1 set
