The thermal shock furnace can be used for a long time at ≤1300℃, with a temperature control accuracy of ±1℃, and the furnace chamber is 200×200×300mm. Controlled by Siemens PLC, it supports switching between air cooling and water cooling, and can operate in full automatic program cycle. It is suitable for testing the thermal shock performance of materials, and is efficient and reliable.
| Parameter | Details |
| Temperature | 1400℃ |
| Model | GWDL-1400RC |
| Equipment Color | RAL 7035 |
| Specification (Furnace Chamber Size) | 200×200×300 (mm) |
| Power Supply (AC) | 380V, 15kW |
| Long-term Operating Temperature | Long-term operating temperature ≤1300℃ |
| Control Range | 500 to 1250℃ |
| Temperature Measuring Element | Thermocouple with division number S, measuring range 0-1720℃ |
| Temperature Control Precision | ±1℃ (integrated circuit control, no overshoot phenomenon) |
| Counter | Siemens PLC module |
| Insulation Timer | Siemens PLC module |
| Heating Rate | Freely adjustable, maximum heating rate 20℃/min |
| Heating Elements | Silicon carbide rods |
| Furnace Body | Processed by CNC machine tools, through polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It adopts a two-color design with a novel and beautiful appearance, and has advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Refractory Materials | The furnace lining is made of vacuum-formed high-purity alumina lightweight materials |
| Insulation Materials | Three-layer insulation: aluminosilicate fiberboard, alumina fiberboard, and alumina (polycrystalline) fiberboard. The energy-saving effect is over 80% compared with old-style electric furnaces. |
| Furnace Shell Temperature | ≤45℃ during long-term continuous operation |
| Protection | Adopts integrated module control unit with accurate control precision, designed with dual-loop control and protection, featuring overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start protection. |
| Control Method | Uses closed-loop thyristor module trigger control (phase-shift trigger mode). Output voltage, current, or power is continuously adjustable with constant voltage, current, or power characteristics. The current loop is the inner loop and the voltage loop is the outer loop. When the load is suddenly applied or exceeds the current limit, the output current is limited within the rated range to protect heating elements from excessive current/voltage impact, ensuring safe and reliable control effect and precision. |
| Display Parameters | Temperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
| Buttons | Imported buttons with a service life of over 100,000 times, equipped with LED indicators |
| Random Accessories | 1 pair of crucible tongs, 1 pair of high-temperature gloves |
| Warranty Scope and Period | The electric furnace is covered by a 1-year free warranty; heating elements are not covered under warranty |
| Configuration Classification | |
| Item | PLC + Touchscreen Automatic Control |
| Temperature Setting | Uses intelligent Yudian 708 temperature controller to communicate and read/write data with PLC and touchscreen |
| Furnace Door Opening Mode | PLC-programmed electric top opening |
| Water Cooling | PLC-programmed electric water inflow |
| Moving Mode | PLC-programmed electric movement |
| Automatic Program Flow | 1. Furnace door opens; 2. Workpiece enters; 3. Timing starts when reaching the set temperature; 4. Workpiece is pulled out; 5. Furnace door closes; 6. Starts air-cooling for rapid cooling timing, or rotates into water tank, or uses air cooling; 7. Returns to step 1 (the number of repetitions can be set) |
