Small Automatic 1700C Elevator Lifting Furnace With Operation Platform
Features
Door opening method: Bottom opening
Control accuracy: ±1°C; furnace temperature uniformity: ±5°C (depending on heating chamber size).
Easy operation: Programmable, PID auto-tuning, automatic heating, automatic soaking, automatic cooling. Optional computer communication for furnace operation (start, stop, pause heating, set temperature profile, store profile, historical curves, etc.).
Fast heating: Heating rate adjustable from 1°C/h to 15°C/min.
Energy saving: Furnace chamber made of alumina ceramic fiber material – high temperature resistance, excellent thermal shock resistance.
Corrosion resistance: The furnace body is finely powder-coated. The furnace body is isolated from the chamber by air cooling; the shell temperature is near room temperature.
Dual-loop protection (over-temperature, over-pressure, over-current, thermocouple break, power failure, etc.).
Furnace chamber material: Premium refractory material – good insulation, high temperature resistance, excellent thermal shock resistance.
Technical Specifications
Parameter | Description |
Maximum Temperature | 1700°C |
Supply Voltage AC | 380V |
Furnace Chamber Dimensions (mm) | Diameter 350 × Height 350 |
Temperature Control Accuracy | ±1°C |
Furnace Temperature Uniformity | ±1°C (depending on heating chamber size) |
Temperature Sensor & Range | Platinum-Rhodium (Type B thermocouple), range 0–1820°C |
Heating Rate | Adjustable: maximum 15°C/min, minimum 1°C/h |
Heating Elements | U-shaped 1800°C molybdenum disilicide (MoSi₂) rods |
Heating Element Installation Position & Method | Vertically installed around the furnace chamber |
Furnace Body | CNC machined, polished, pickled, phosphated, powder-coated and baked at high temperature. Two-tone color scheme – aesthetically pleasing. Features anti-oxidation, acid/alkali resistance, corrosion resistance, high temperature resistance, and easy cleaning. |
Furnace Structure | Air-cooled double-layer structure with effective airflow guide plates to ensure full cooling circulation. Discharges hot air after cooling the heating element conductors – prevents high-temperature oxidation of conductors and ensures a good working environment. |
Furnace Outer Shell Temperature | <45°C under continuous long-term operation |
Insulation Material | Four-layer insulation: alumina fiber wool, alumina fiber board, polycrystalline alumina fiber board, vacuum-formed high-purity alumina fiber lightweight board – energy saving >80% compared to traditional furnaces. |
Protections | Integrated modular control unit with high accuracy. Dual-loop control and dual-loop protection, including protections against overshoot, over-regulation, under-regulation, broken thermocouple, phase loss, overvoltage, overcurrent, overtemperature, current feedback, soft start, etc. |
Control Method | Closed-loop SCR (thyristor) module triggering – phase-shift or zero-crossing control. Continuous adjustment of output voltage, current or power with constant voltage, constant current or constant power characteristics. Inner current loop and outer voltage loop – limits output current within rated range under sudden load or overcurrent conditions, ensuring stable operation and protecting heating elements from excessive current/voltage surges, achieving safe and reliable control and high accuracy. |
Displayed Parameters | Temperature, segment number, segment time, remaining time, output power percentage, voltage, current, etc. |
Pushbuttons | Pushbutton life >100,000 cycles, with LED indicators. |
Temperature Profile Setting | Touch screen for temperature curve setting |
Cooperation Between Furnace Opening and Loading Table Refractory | Step cross sealing is used. Both the refractory material of the furnace opening and the loading table have angled surfaces. The opening angle of the loading table is large and gradually decreases as the loading table closes. |
Loading Table Material | Alumina ceramic fiber material; moves up and down for loading/unloading |
Loading Lifting Speed | 5–30 s |
Loading Capacity | 50 kg |
Lifting Mechanism | Electric mechanical |
Cooling Structure | Double-layer furnace shell, air-cooled |
Warranty & Coverage | One-year free warranty for the furnace. Heating elements are not covered. |
Standard Accessories | Two heating elements, two sets of electrode rods, one instruction manual, one certificate of conformity, one pair of crucible tongs, one pair of high-temperature gloves |
