Sheet metal processing of thick plate in the use of which we can modify it
The current through in sheet metal processing
oxygen flow was added around the flame preheating; in cutting oxygen flow around
adding auxiliary oxygen flow, or the inner wall of the reasonable design of the
nozzle, improve the flow field characteristics of airflow to improve the plate
sheet metal processing in the presence of problems and difficulties.
Plate
thickness direction of oxygen purity and pressure to maintain constant, decrease
in oxygen purity also affect the quality of incision, increasing the supply gas
pressure, the flow field of the nozzle easy to the formation of the shock and
sheet metal processing in the cutting process has a lot of harm, reduce the
purity of oxygen flow, affecting the cutting quality.
Quasi steady state
combustion process and maintain more difficult, actual cutting plate process,
can cut through the plate thickness is limited and combustion process to
continue, cut the temperature at the top of the seam must achieve ignition, but
actually cannot ensure combustion process continues, the combustion process is
period of of, this will lead to temperature fluctuations in the frontiers of
sheet metal processing, cutting quality becomes poor.
Sheet metal processing
for 10mm thick plate cutting a cinch, and if to be processed more thick plate
cutting effect is obviously insufficient, also need to greater laser power
cutting machine to achieve. But more than 10mm steel processing in technology or
requirements are relatively high, the difficulties
