[Single Quench]
For transfer quenching, starting and ending point of heating and cooling overlaps leading to cracks or reduced hardness.
With Fuji Electronic all around single shot quenching, a complete uniformed quenching layer can be produced even a slewing ring size of diameter of 1.8m and module of 15. Also, comparing to transfer quenching, improved productivity, 1/5 work speed, and 1/2 ~ 1/3 electricity consumption.

[Carburizing]
Once the heating process has completed, by simultaneously dipping the product into the cooling water and blasting water current through jackets, helps to prevent from entering while forming a uniformed quenched layer.
In addition, by controlling quenching water temperature and stir speed, an effect layer can be controlled precisely.

[Inner and Outer Diameter Simultaneously Heating]
By having two electrical switches on both sides, the inner and outer layer can be quenched simultaneously with low distortion.
