Can Hybrid Furnace be used for heat treatment experiments?

The tube furnace box type furnace integrated Hybrid Furnace can be fully used for heat treatment experiments. Its modular design and functional integration characteristics enable it to meet the heat treatment needs of various materials such as metals, ceramics, and composite materials. The specific advantages and application scenarios are as follows:

1. The core capability of Hybrid Furnace to support heat treatment experiments
Multi mode heating system
Tube furnace module: provides precise temperature control (± 1 ℃) and rapid heating, suitable for small-sized samples or heat treatment requiring atmosphere protection (such as vacuum, inert gas, reducing gas environment).
Box furnace module: equipped with a large capacity constant temperature zone, suitable for large-sized samples or batch processing, with a temperature uniformity error of ≤ 3 ℃, meeting the requirements of uniform heating.
Joint mode: The collaborative work of tube furnace and box furnace is achieved through program control. For example, after the tube furnace rapidly heats up to the target temperature, it is transferred to the box furnace for insulation or cooling, realizing complex process flow.
Flexibility in atmosphere control
Supports various atmospheres such as vacuum (with a vacuum degree of up to 10 ⁻ Pa), nitrogen, argon, hydrogen, etc., which can prevent materials from oxidizing or undergoing chemical reactions during heat treatment. For example, nitrogen gas is introduced during metal annealing to prevent surface oxidation; When deoxidizing ceramic materials, hydrogen gas is introduced for reduction.
Gradient temperature control and dynamic adjustment
The intelligent temperature control system supports multi-stage programming (such as 2 sets of 16 segments), which can achieve temperature gradient control, segmented insulation or cooling rate adjustment. For example, in the quenching process, the tube furnace rapidly heats up to the austenitizing temperature, while the box furnace controls the cooling rate to obtain the martensitic structure.

2. Typical application scenarios for heat treatment experiments
a. Heat treatment of metal materials
Annealing treatment:
Application: Relieve metal processing stress and improve plasticity.
Case: Aluminum alloy sheet is air cooled after being kept at 600 ℃ for 2 hours in a box furnace, resulting in grain refinement and a 20% increase in elongation.
Hybrid advantage: The box furnace has a large capacity and is suitable for batch processing, while the tube furnace can assist with local annealing.
Quenching and tempering:
Application: Improve metal hardness and strength.
Case: After austenitizing at 850 ℃ in a tube furnace, 45 # steel is quickly transferred to oil quenching and then tempered at 200 ℃ in a box furnace, achieving a hardness of HRC50.
Hybrid advantage: The tube furnace heats up quickly to reduce decarburization, while the box furnace precisely controls the tempering temperature.
Solution treatment:
Application: Improve the corrosion resistance of metals.
Case: Stainless steel undergoes solution treatment at 1050 ℃ in a tube furnace, followed by water cooling to dissolve carbides and improve its resistance to intergranular corrosion.
Hybrid advantage: Tube furnace atmosphere protection prevents oxidation, and box furnace can assist in subsequent aging treatment.
b. Heat treatment of ceramic materials
Stress relief annealing:
Application: Relieve ceramic processing stress and reduce the risk of cracking.
Case: Zirconia ceramics were kept at 300 ℃ for 1 hour under nitrogen protection in a tube furnace, resulting in a decrease in residual stress.
Hybrid advantage: precise temperature control at low temperatures in tube furnaces, avoiding ceramic phase transition.
Sintering auxiliary processing:
Application: Optimize ceramic density and grain structure.
Case: After hot pressing and sintering silicon nitride ceramics at 1800 ℃ in a box furnace, nitrogen gas is introduced into a tube furnace for post-treatment, resulting in improved fracture toughness.
Hybrid advantages: Box furnace high-temperature and high-pressure sintering, optimized interface for tube furnace atmosphere control.
c. Composite material heat treatment
Fiber reinforced ceramic matrix composites:
Application: Improve the interface bonding between fibers and matrix.
Case: Carbon fiber reinforced silicon carbide composite material was treated at 1200 ℃ under argon protection in a tube furnace, resulting in an increase in interfacial shear strength.
Hybrid advantage: The tube furnace has precise temperature control to prevent fiber damage, while the box furnace can assist in batch processing.
Metal ceramic gradient materials:
Application: Implement performance gradient distribution.
Case: Using the gradient temperature control system of Hybrid Furnace, a transition layer from metal to ceramic was prepared with matching thermal expansion coefficient to reduce cracking.
Hybrid advantage: Multi segment programming enables temperature gradient and supports complex process design.
