Various steps of centrifugal casting
1. Melting Rawmaterial, being scrap and alloying elements is melted in an induction furnace with a maximum capacity of about 850 kg molten weight per charge. Before casting, test samples of each charge are taken and checked in the foundrys own spectrometer to safeguard that the chemical analysis corresponds to the specification and the customers requirements.
2. Sanding the ingot mould Whilst the melting process continues the ingot moulds are prepared.

3. The melt The molten steel is poured into a ladle for onward transport to the ingot moulds.

4. Test specimen A test specimen is taken from each charge and sent to a lab for strength- and other testing thereby controlling that the material corresponds to the strength values applicable to the ruling standard.

5. Ingot mould Via a funnel and a hole in the center of the gable the molten steel is poured into the rotating ingot mould. Due to the rotation the melt is pressed against the moulds wall and a tubular blank is formed.

6. Rotation During solidification the mould rotates with such a speed that a pressure of 70 to 100 G against the moulds wall is generated, resulting in a solid tubular steel blank, free from pores and other inclusions.

Machining Machining is performed in modern premises and with appropriate machines. With our extensive equipment, both big and small, and mainly computer controlled, we can offer the customer the most cost efficient solution. We do rough- and/or final machining of components according to customers requirements thereby sharing our knowledge and competence with them.
