Application of Box type Atmosphere Annealing Furnace in the Metal Industry

Box type atmosphere annealing furnaces are widely and crucially used in the metal industry. The following will elaborate on different metal materials and specific application scenarios:

1. Application of different metal materials
ferrous material
Annealing treatment: Box type atmosphere annealing furnace can be used for annealing treatment of steel materials, such as quenching and tempering treatment of valve springs for automotive engines. Heating the valve spring to 850 ℃ -880 ℃ and quickly quenching it in oil, followed by tempering it in a box type atmosphere furnace at 450 ℃ -500 ℃, can achieve high strength and elastic limit of the valve spring, meet the performance requirements of the engine for valve spring during high-speed operation, and improve the reliability and durability of the engine.
Stress relief annealing: For some steel materials or workpieces that have been cast, forged, welded, or cut, they can be slowly heated to a certain temperature through a box atmosphere annealing furnace, held for a period of time, and cooled at an appropriate speed to eliminate residual stress and improve plasticity and toughness.
non-ferrous metal
Aluminum alloy: In the research of metal materials, researchers can use a box type atmosphere furnace to accurately control the heating temperature and insulation time when studying the aging strengthening characteristics of new aluminum alloys. If the new aluminum alloy samples are kept in a box atmosphere furnace at 180 ℃ -200 ℃ for different periods of time and then taken out, the influence of aging temperature and time on the microstructure and properties of the aluminum alloy can be analyzed through hardness testing, metallographic observation, and mechanical property testing, providing theoretical basis and technical support for the development and application of new aluminum alloys.
Copper alloy: can be used for annealing treatment of copper alloys to improve their conductivity and ductility, such as in the fields of wires and cables, electronic connectors, etc.
High-temperature alloy
Aircraft engine blade treatment: High temperature alloy blades of aircraft engines are one of the key components, and their performance directly affects the performance and reliability of the engine. The use of a box type atmosphere furnace for solid solution treatment and aging treatment of high-temperature alloy blades, such as solution treatment in a box type atmosphere furnace at 1050 ℃ -1100 ℃, and aging treatment at 750 ℃ -850 ℃, can achieve good high-temperature strength, fatigue resistance, and oxidation resistance of the blades, meeting the requirements of aircraft engines in harsh working conditions such as high temperature, high pressure, and high speed.
die steel
Spheroidization annealing treatment: Mold steel needs to be pre treated before manufacturing molds to improve its processing performance and microstructure properties. Box type atmosphere furnace can be used for spheroidizing annealing treatment of mold steel, such as heating Cr12MoV mold steel to 780 ℃ -800 ℃, holding for 2h -4h, and then slowly cooling it to below 500 ℃ in the furnace and air cooling it out of the furnace. This can spheroidize carbides in the mold steel, reduce hardness, improve cutting performance, prepare the structure for subsequent processing and final heat treatment, and ultimately improve the accuracy and service life of the mold.

2. Specific application scenarios
Automotive parts manufacturing
In addition to the treatment of valve springs mentioned above, it can also be used for annealing treatment of other metal parts in automobiles to improve their performance and quality, and extend their service life.
aerospace field
In addition to the treatment of high-temperature alloy blades, it can also be used for heat treatment of other special metal materials in the aerospace field, ensuring the stability of material performance in extreme environments.
Electronic component manufacturing
Annealing treatment is performed on metal sheets used for manufacturing electronic components to eliminate stress generated during processing, improve material flexibility and conductivity.
