| Extrusion Press - Rapidfire™
heating |
| |
|
This oxy-fuel technology using direct flame impingement is
ideal for the rapid heating of billets prior to extruding.
Heating rates greater than 100°C/min (or 200°C/min
for highly conductive metals such as copper) are typical on
100mm diameter, non-ferrous metal billets. This proprietary
technique yields fuel savings, higher productivity and improved
surface quality.
Extrusion Press - Reheat Furnace Enrichment
|
| |
|
Oxygen is injected into the furnace to increase productivity,
reduce flue gas volume and allow a more stable flame. The
cost of oxygen is offset against fuel savings.
Extrusion Press - Die Cooling / Inerting
|
| |
|
Injecting gaseous or liquid nitrogen into the die tooling
area can minimise oxide formation by displacing the oxygen-laden
air. Additionally, heat generated by the extrusion process
is removed. The resultant decrease in oxide build-up on the
die bearing surface allows productivity increases as high
as 30%, while the nitrogen used typically pays for itself
with productivity gains of as little as 2%. The inerting effect
also acts on the product to enhance final part quality and
decrease reject rates. More financial benefits are possible
from extended die life.
Rolling Mill - Rapidfire™ heating
|
| |
|
This oxy-fuel technology using direct flame impingement is
ideal for the rapid heating of billets and slabs prior to
rolling. Heating rates greater than 100°C/min (or 200°C/min
for highly conductive metals such as copper) are typical on
100mm diameter, non-ferrous metal billets. This proprietary
technique yields fuel savings, higher productivity and improved
surface quality.
