LINESKJØT
KONSTRUKSJON
Skjøten består av et hovedrør i aluminium belagt med eksplosiver.
For feral-liner benyttes i tillegg et stålrør over stålkjernen, som i de fleste tilfeller er belagt med et utfyllingsrør med diameter tilsvarende linediameteren. Stål-liner skjøtes med et enkelt stålrør belagt med eksplosiv.
HOT PRESSING
We have a 500 t press for forging aluminum AA 6000 leg and high-strength AA 7000 leg. With up to 450 N / mm2 in tensile strength, as well as brass alloys and copper. We design and build hot press tools ourselves, or in collaboration with our partners.
HOW IT IS DONE
AAutomatic cutting of bolt
The bolt is heated to:
*Al from 480 – 540 °C depending on alloy and product.
*Ms from 720 - 800 °C
*Copper from 800 - 850 °C
Hot pressing
Cooling
Grading in the press, possible machining, surface treatment and / or shavings winding / drumming.
BENFITS
Great freedom in the products shape
Surface finish – no machining needed
Good product grain structure
High fatigue strength
High material utilization
VP Metall AS has both hot pressing and machining. We therefore have high process adaptability competence.
