Product Definition
The Low Temperature Annealing Furnace is a precision heat treatment furnace designed for annealing processes carried out at relatively low temperatures, typically used to relieve internal stress, improve ductility, stabilize material structure, and enhance processing performance without significantly changing the metal's hardness or mechanical strength.
Working Principle
The working principle of a low-temperature annealing furnace is based on the theories of solution treatment and precipitation hardening in metal heat treatment. By controlling the heating temperature and heating duration, the furnace causes phase transformations within the metal structure, thereby changing the mechanical properties of the material.
For most metal materials, the internal structure gradually changes as the heating temperature increases. When the temperature reaches a certain level, the isotropy of the crystal system begins to diminish, the crystal grains grow larger, and the atomic spacing increases, resulting in reduced thermal stability of the material.
At this stage, the material gradually softens, and the internal stresses are progressively relieved.
Features
Preserves original material properties
Low-temperature annealing operates at relatively low heating temperatures and shorter processing times, without altering the shape of the workpiece, while retaining the original properties of the material.
Improves corrosion resistance
After treatment, the workpiece surface becomes smoother and more uniform, making it easier to form a dense oxide film and effectively enhancing corrosion resistance.
Optimizes overall mechanical properties
The process refines grain boundaries and improves grain structure uniformity, thereby enhancing mechanical properties such as hardness, strength, and toughness.
Applications
Low temperature annealing furnaces are widely used in industries such as machinery manufacturing, electronics, chemical engineering, aviation, and aerospace.
In the machinery manufacturing industry, low-temperature annealing furnaces are mainly used for annealing metal components that have undergone severe deformation.
In the electronics industry, they are commonly used in the manufacturing of semiconductor chips.
In the aviation and aerospace sectors, low-temperature annealing furnaces are primarily used to improve the brittleness and fatigue performance of metal materials, thereby enhancing material durability and service life.
