As a high-temperature heat treatment equipment adopting double-station alternate operation, the double-platform trolley furnace features multi-zone temperature control with uniformity of ±5℃ and 30-segment program temperature control. It uses ceramic fiber for heat preservation, saving over 30% energy. Equipped with multiple safety protections and customizable furnace chambers, it is the first choice for batch heat treatment.
The double-platform trolley furnace is a high-efficiency, flexible high-temperature heat treatment device, specifically designed for high-volume, continuous production needs. Featuring a dual-station platform plus trolley structure, it enables alternating loading and unloading—greatly boosting production efficiency. It’s ideal for heat treatment processes like annealing, normalizing, quenching, tempering, and sintering of large workpieces (such as castings, forgings, and molds), standing out as a high-efficiency, energy-saving precision electric furnace.

| Heating Elements | 1800-type silicon molybdenum rods on the left and right sides of the furnace chamber |
| Furnace Shell Material | Processed by CNC machine tools, with processes including polishing, grinding, pickling, phosphating, plastic powder spraying, and high-temperature baking. It features a two-color design, novel and attractive appearance, and advantages such as oxidation resistance, acid and alkali resistance, corrosion resistance, high-temperature resistance, and easy cleaning. |
| Furnace Shell Color | RAL7035 |
| Furnace Body Structure | Air-cooled double-layer structure. Effective air-cooled guide partitions enable overall cold air circulation in the furnace shell, which finally cools the heating element conductive plates before being discharged, avoiding high-temperature oxidation of the conductive plates and ensuring a good working environment. |
| Furnace Door Opening Method | The furnace door and bottom are integrally designed, with an electric opening mechanism. A motor-driven reducer drives the loading platform in and out, equipped with limit switches. |
| Cooperation Between Furnace Mouth and Loading Platform Refractories | The furnace mouth and loading platform refractories adopt a stepped cross-sealing design, with angles on both upper and lower parts of the refractories. The opening angle of the loading platform increases, and gradually decreases as the platform closes. |
| Loading Platform Capacity | 1000kg |
| Loading Platform Movement | Electric mechanical |
| Refractory Materials | The furnace lining uses vacuum-formed high-purity alumina fiber lightweight plates. Positions prone to collision during material handling (furnace mouth, furnace bottom) use lightweight hollow spherical alumina plates, featuring high operating temperature, low heat storage, resistance to rapid heating/cooling, no cracking, no slag dropping, and good thermal insulation performance (energy-saving effect is over 80% compared to old-fashioned electric furnaces). |
| Insulation Materials | Three-layer insulation: high-alumina cotton, alumina blanket, and alumina fiberboard, with an energy-saving effect over 80% compared to old-fashioned electric furnaces. |
| Furnace Body Surface Temperature | ≤45℃ during long-term continuous operation |
| Protection | Adopts an integrated module control unit with accurate control precision, designed with dual-loop control and dual-loop protection, featuring overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start protection. |
| Control | 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 of the voltage regulator is limited within the rated range to ensure normal operation of the output and regulator. The voltage loop also participates in regulation to maintain stable output current and voltage within the rated range, thus protecting heating elements from excessive current/voltage impact and ensuring safe, reliable control and precision.

| Temperature Curve Setting | Uses an intelligent temperature controller with multiple regulation modes (standard PID, artificial intelligence adjustment APID, MPT, etc.), featuring self-tuning and self-learning functions, no overshoot/undershoot, and 30-segment program control. It supports arbitrary slope heating/cooling control, with programmable commands (jump/cycle, run, pause, stop) and allows in-operation program modification. Adopts an AI adjustment algorithm with curve fitting function for smooth curve control. (See electric furnace video for details) |
