Business Introduction
ゴーホグカジノcal Steel Strip Products
ゴーホグカジノcal steel strip to become a global brand. Meeting the needs for high efficiency and compactness.
The need for more efficient and smaller iron cores using electrical steel strips is increasing in the electric power, renewable energy, industrial equipment and motor fields.
NIPPON KINZOKU group is the only supplier of ゴーホグカジノcal steel strip with a thickness of less than 0.1 mm in Japan, based on rolling technology cultivated over many years in order to meet these needs.
We also have more than 50 years’ experience in the production and sales of electrical steel strips, and our track record of integrated production, from materials to products such as reactors, has earned the high trust of our customers both in Japan and abroad.
Features of NIPPON KINZOKU’s ゴーホグカジノcal steel products
- Low iron loss
- Thinner plate thicknesses enable eddy current losses to be reduced and iron losses to be lowered.
- Downsizing
- ゴーホグカジノcal steel strips have a higher magnetic flux density than other materials, therefore contributing to the miniaturisation of the iron core.
- Optimal usage range
- The high flux density compared to other materials at usage frequencies of 400 Hz to 40 kHz enables downsizing of reactors, motors, etc.
- Insulation coating
- ゴーホグカジノcal steel strips have excellent insulation resistance and make the most of their material properties.They have a high heat resistance temperature and are able to maintain a stable film even at high temperatures (up to 850℃).
- Raw material
- ゴーホグカジノcal steel strips are made from Fe-3% Si steel (raw material from Nippon Steel).
Low iron loss
TThinner plate thicknesses enable eddy current losses to be reduced and iron losses to be lowered.
Example of low iron loss effect with thinner thickness
■ In the case of magnetic flux density 1.0T and frequency 20kHz
Grain oriented ゴーホグカジノcal steel strips: GT050
t0.23mm → t0.05mm: Iron loss reduced by 75%!
Non-Grain oriented ゴーホグカジノcal steel strips: ST050
t0.15mm → t0.05mm: Core loss reduced by 40%!
Downsizing
ゴーホグカジノcal steel strips have a higher magnetic flux density than other materials, therefore contributing to the miniaturisation of the iron core.
Cross-sectional area comparison with constant magnetic flux
■ Cross-sectional area comparison with constant magnetic flux
Ferrite (Mn-Zn based) →Ultla-thin electrical steel strip: 85% downsizing!
High-silicon steel plate → Ultla-thin electrical steel strip: 30% downsizing!
Optimal usage range
The high flux density compared to other materials at usage frequencies of 400 Hz to 40 kHz enables downsizing of reactors, motors, etc.
Insulation coating
ゴーホグカジノcal steel strips have excellent insulation resistance and make the most of their material properties.They have a high heat resistance temperature and are able to maintain a stable film even at high temperatures (up to 850℃).
Raw material
Relations between Si content, formability and magnetic properties of electrical steel strips
Our ゴーホグカジノcal steel strips are made from Fe-3% Si steel (Raw material from Nippon Steel Corporation).
