Electric Furnace For Heat Treatment

1.Eliminating Internal Stress
Internal stresses generated during forming and cold working processes are released by holding the material at an appropriate temperature for an extended period.

2.Softening the Material
The material's plasticity is increased, facilitating subsequent processing (such as cold bending, stamping, and drawing).

3.Adjusting Grain Structure
Through heating, isothermal holding, and slow cooling, the grain size is increased or refined to obtain the desired microstructure (such as pearlite, ferrite, etc.).

4.Improving Electrical and Magnetic Properties
Annealing, especially of electrical steel and magnetic materials, has a significant impact on properties such as magnetic permeability and loss.

1.Steel and non-ferrous metal processing industry

electric annealing furnaces are applied to the annealing of steel plates, strips, wires, tubes, as well as aluminum and copper materials. The annealing process reduces material hardness, relieves internal stresses generated during cold working, and improves ductility and formability, making the materials suitable for subsequent rolling, drawing, bending, or stamping operations.

2.Machinery manufacturing and bearing industry

annealing furnaces are commonly used for heat treatment of bearing rings, rolling elements, gear blanks, and other mechanical components. Annealing improves microstructural uniformity, enhances machinability, and provides a stable metallurgical structure for subsequent quenching or tempering processes.

3.Hardware and metal stamping industry

electric annealing furnaces are used for annealing springs, fasteners, connectors, and stamped parts. The annealing process increases plasticity, reduces the risk of cracking during forming, and improves dimensional stability and service life of finished products.

4.Electrical steel and magnetic materials industry

annealing furnaces are applied to the heat treatment of electrical steel sheets, silicon steel, and magnetic alloys. Precise temperature and atmosphere control significantly improve magnetic permeability and reduce core losses, contributing to higher efficiency in motors, transformers, and other electrical equipment.

5.Automotive, aerospace, and high-end equipment manufacturing industries

electric annealing furnaces are used for heat treatment of high-strength alloy steels, stainless steels, and special alloys. Due to their high temperature accuracy, process repeatability, and clean heating characteristics, they meet stringent requirements for material performance consistency, reliability, and quality control.

1. What are the core advantages of CHTEE's heat treatment furnaces in terms of structural design?
We utilize a modular furnace body structure design, combined with finite element thermal simulation (Thermal FEM) to optimize the furnace lining thickness, heating zone distribution, and airflow path. This significantly improves temperature uniformity and reduces energy consumption while ensuring structural strength.

2. How does the equipment meet the requirements for temperature gradient and heating rate for different processes?
Through a multi-zone independent temperature control system (Multi-zone PID Control), differentiated heating, holding, and cooling curves can be set for different process stages. Temperature control accuracy can be stably maintained within ±3℃ (depending on the furnace type).

3. In terms of atmosphere furnaces, how does CHTEE ensure the stability of the furnace atmosphere?
We integrate a high-precision gas mass flow control system (MFC) and combine it with an online oxygen probe or dew point analyzer to achieve real-time closed-loop control of carbon potential, oxygen potential, or dew point, effectively preventing decarburization, oxidation, or uneven carburization.

4. How does the equipment maintain process consistency during long-term continuous operation?
Answer: Through an automatic process parameter compensation algorithm, the system can automatically correct control parameters based on furnace temperature drift, furnace lining aging, and changes in furnace load, ensuring long-term batch stability.
