Tube furnace All are new-generation, high-performance, energy-efficient electric furnaces developed using advanced technologies, available in a variety of configurations, including single-tube, double-tube, horizontal, open-type, vertical, single-zone, dual-zone, and triple-zone models. They are primarily used for laboratory experiments and small-batch production in colleges and universities, research institutes, and industrial and mining enterprises. These furnaces feature safety and reliability, simple operation, high temperature-control accuracy, excellent heat retention, a wide temperature range, superior furnace-chamber temperature uniformity, multiple heating zones, and optional atmospheres and vacuum-capable designs.
 
Optional configurations include a single setpoint controller or a 30-segment programmable controller. The energy-efficient ceramic fiber insulation and double-wall construction reduce the outer surface temperature to ambient levels. The furnace features a long uniform-temperature zone, simple operation, reliable sealing, and superior overall performance, placing it at the leading domestic level. The furnace tube can be configured with materials such as heat-resistant steel, quartz glass, or ceramic tubing.

　　Tube furnaces are all batch-operated. They are used in laboratories, industrial and mining enterprises, and research institutions for elemental analysis as well as for the quenching, annealing, and tempering of small steel parts and for heating new materials such as electronic ceramics.
　　The complete equipment package includes temperature controllers, thermocouples, compensation leads, and other components. Temperature control can be implemented via relay-based control or thyristor-based control; given that this is an intermittent-operation furnace, a 40-segment PID programmable controller is typically used to ensure precise control of the product firing process.

Characteristics of Tube-Type Electric Furnaces
1. Control accuracy: ±1°C; furnace temperature uniformity: ±1°C (depending on the size of the heating chamber).
2. The furnace tube is made of quartz glass.
3. Stainless steel metal flange seal (double rubber gasket)
4. The furnace body is coated with a high-quality, corrosion- and acid/alkali-resistant powder finish; the furnace body is thermally isolated from the combustion chamber by air cooling, keeping the furnace wall temperature close to ambient.
5. Dual-circuit protection (overtemperature, overpressure, overcurrent, phase failure, power outage, etc.)
6. Imported refractory materials with excellent thermal insulation and high temperature resistance.
7. Vacuum gauge: vacuum level from 0 to -0.1 MPa
8. The electric furnace can be purged with various gases (oxygen, nitrogen, argon, hydrogen, etc.).
9. Temperature classes: 800°C, 1000°C, and 1200°C—three options.
10. Utilizes reliable integrated circuits, ensuring a favorable operating environment with strong anti-interference capabilities; at the maximum operating temperature, the furnace shell temperature does not exceed 50°C, significantly enhancing the working conditions. Microcomputer program control allows for programming of two sets of 16-segment heating/cooling curves, enabling fully automatic heating and cooling. During operation, temperature-control parameters and programs can be modified, offering flexible, convenient, and simple operation. Temperature-control accuracy: ±1°C; constant-temperature accuracy: ±1°C. The heating rate is rapid, with a maximum heating rate of ≤5°C/min. All furnace chamber materials are made from imported Morgan fiber, providing high service temperatures, low heat storage, and excellent thermal insulation (energy-saving performance exceeds 80% compared with conventional electric furnaces). The design is rational, featuring a double-layer inner-and-outer furnace structure with air-cooling for heat dissipation, which substantially shortens the test cycle.
This product is an essential instrument for testing and evaluation in fields such as refractories, electronics, ceramics, metallurgy, machinery, building materials, specialty materials, and new-material development.
