The furnace controls temperature within 50-1000℃, with an adjustable heating rate of 1-15℃/min. It features a 316L stainless steel inner liner and alumina materials, achieving over 80% energy savings. The outer shell temperature is ≤55℃, equipped with dual-loop protection, making it suitable for high-temperature processing in various scenarios. It is a dedicated high-temperature equipment for laboratories and industrial and mining enterprises.
The heating element of this equipment is a high-temperature alloy resistance strip, which is used to generate heat. This equipment is a dedicated device developed for laboratories in institutions of higher learning, scientific research institutes, and industrial and mining enterprises. It can be used to perform operations such as sintering, melting, analyzing, and producing materials in various fields, including ceramics, metallurgy, electronics, glass, chemical engineering, machinery, refractory materials, new material development, special materials, building materials, metals, non-metals, and other compounds.
The furnace lining material is made entirely of a high-purity alumina lightweight material formed by vacuum molding. This material can withstand high temperatures, has a low heat storage capacity, is resistant to rapid heating and cooling, does not crack or shed slag, and has excellent heat insulation performance. The energy-saving effect is more than 60% higher than that of old-fashioned electric furnaces. The equipment has a reasonable structure, with an inner and outer double-layer furnace jacket and air-cooled heat dissipation, which can significantly shorten the test cycle.

The upper and lower parts can be separated. |
| Inner Liner | Sealed, made of 316L stainless steel (provided by the customer) |
| Refractory Materials | The furnace lining is made of vacuum-formed high-purity alumina lightweight materials. 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 | High-alumina fiber folding blocks, with an energy-saving effect over 80% compared to old-fashioned electric furnaces |
| Furnace Body Surface Temperature | ≤55℃ during long-term continuous operation |
| Protection (provided by customer) | 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 (provided by customer) | Uses closed-loop thyristor module trigger control (phase-shift trigger or zero-crossing 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.
