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. Rolling Mill - Reheat Furnace Enrichment Oxygen is injected into the furnace to increase productivity,
