[Case Study of Solution through IH Heat Treatment] Hardness is not achieved.

If the material structure is not appropriate, no matter how much you harden it, the hardness will not increase!

We would like to introduce a case study from Fuji Electric Industry, which has always been committed to solving the technical challenges faced by our customers as an expert in IH heat treatment. In this case, FCD600 material is used. High-frequency quenching, which allows for processing in a short time, is characterized by being more susceptible to the effects of material, such as segregation, compared to atmosphere heat treatment like carburizing furnaces. There are instances where the quality of heat treatment is affected by the material, and especially for castings, there tends to be greater variability between lots compared to other steel materials. 【Case Overview】 ■ Material: FCD600 ■ Hardness Standard: HRC 46 or higher *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention that you saw this on "Ipros." Response hours: Monday to Friday, 9 AM to 5 PM.

[Case Study of Solutions through IH Heat Treatment] Want to improve productivity and quality.

Introducing a case where quality and productivity were improved through one-shot hardening with semi-open coils!

Traditionally, workpieces were moved and subjected to low-speed quenching, taking 360 seconds per piece to quench a single workpiece. This allowed for only 10 pieces to be processed per hour, which posed a challenge due to low productivity. Therefore, we adopted our one-shot heating immersion quenching. The heating time is significantly shorter compared to moving quenching, reducing the cycle time to 90 seconds per piece, which is one-fourth of the conventional time, achieving a substantial increase in production capacity. [Case Study] ■ Challenge: Low productivity, processing only 10 pieces per hour ■ Proposal: Adoption of one-shot heating immersion quenching ■ Result: Achieved a significant increase in production capacity *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros" as a reference.

Martensite and residual austenite

Is retained austenite a villain?

First, by heating iron above the transformation point temperature, it is converted into an austenite structure, allowing many carbon atoms to enter the iron atoms. Next, by rapidly cooling it, a very hard structure (martensite structure) is formed, in which many carbon atoms are trapped within the iron atoms in a cramped arrangement. This is called martensitic transformation, and the hardness after quenching increases with the amount of carbon. When cooling from austenite, the faster the cooling rate, the more martensite structure is formed. The temperature at which martensitic transformation occurs, known as the Ms point, decreases with an increasing amount of carbon, and the temperature at which the transformation ends, known as the Mf point, also decreases. The austenite structure that could not transform remains as "residual austenite." If left alone, residual austenite may gradually transform, potentially causing issues such as distortion or cracking. Therefore, it is necessary to forcibly transform it into martensite or stabilize the structure. However, since residual austenite has a lower hardness compared to martensite, in cases where wear resistance is required, such as on gear tooth surfaces, the sliding properties of residual austenite may also contribute positively.

[Case Study 5 on Heat Treatment Challenges] A must-see for those troubled by cracking!

"One-shot quenching" significantly reduces heating time, contributing to increased productivity!

Steel may seem very sturdy and stable, but if the heat treatment conditions or management methods are incorrect, it can easily crack. Many cracks are so small that they cannot be seen with the naked eye, and if used without noticing them, they can lead to damage starting from the cracks, potentially resulting in serious accidents. With Fuji Electronic Industry's one-shot quenching, it is possible to achieve a uniform hardened layer through overall heating/cooling with coils that follow the profile. Since the heating time is significantly reduced, the cycle time is less than half compared to conventional moving quenching, contributing to increased productivity. *For more details, please refer to the PDF materials or feel free to contact us.

High-frequency hardening and reheating equipment

At Fuji Electric Industry, high-frequency annealing is referred to as "reheat," distinguishing it from annealing using a furnace.

The target workpiece is a pipe-shaped workpiece placed horizontally in the heat treatment station at the center of the photo. This machine accommodates a wide variety of workpieces with different diameters and lengths through changeovers. Compared to passenger cars, the production volume of trucks is lower, and there are many types of the same parts, so the loading and unloading of workpieces is done manually through the central opening. The green unit above the workpiece is the heating coil, and the gold unit below the workpiece is the cooling jacket. After the workpiece is loaded, it descends with the receiving jig, is held up by center jigs on both sides, and the model identification is performed. After identification, it is moved sideways to the cooling jacket below the corresponding model's coil, where the coil descends from above, and the workpiece is rotated while heat treatment is performed. ★ For inquiries by phone, please contact us here: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 * When calling, please mention "Ipros was seen."

[Case Study of Solution through IH Heat Treatment] Out of tolerance due to distortion.

Our company is engaged in efforts and development to minimize distortion in various components.

There are various factors that cause dimensional changes, but broadly speaking, they can be categorized into two main types: "dimensional changes due to the release of residual stress" and "dimensional changes due to structural transformation (phase change)." Minimizing distortion in precision parts is extremely important, as forcing correction can lead to the risk of cracking, and the strength gained from hardening will undoubtedly decrease. Therefore, our company is engaged in efforts and development to minimize distortion in various components. In particular, when changing processes from atmospheric treatment to high-frequency hardening, significant effects can be expected. If you have concerns about distortion, please feel free to consult us. *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention that you saw us on "Ipros."
