R6M three strands full arc square and round steel billet continuous
casting machine/CCM
CCM is mainly composed of ladle, tundish, mould (primary cooling),
mould oscillating unit, secondary cooling and casting billet guide
device, withdrawal and straightening unit, cutting unit, billet
discharge unit (conveying roller), etc.
Curved continuous casting process flow:
Qualified molten steel from steel refining furnace will be poured
into steel ladle, then it will be delivered to the position above
the CCM after external refining processing, and molten steel will
be poured into the tundish from ladle bottom outlet. Tundish nozzle
shall be adjusted to match with the lower mould in advance.
After opening the tundish stopper or sliding nozzle (or sizing
nozzle), molten steel will flow into forced water-cooled copper
mould. The mould has no bottom, so the drop bottom is required
before filling with molten steel, meanwhile the drop bottom play a
role in drawing out the casting billet and it is called dummy bar.
The molten steel inside the mould will be quickly cooled into
crystals; meanwhile molten steel front will be solidified together
with the head of dummy bar at the bottom of mould.
The rear end of dummy bar is clamped in the withdrawal roller of
billet withdrawing machine, and billet withdrawing machine and
mould oscillating unit will be started simultaneously when molten
steel inside the mould reach to required height and solidified
shell, at the mould lower outlet, reach to a certain thickness.
Withdrawal and straightening machine will pull out the dummy bar
(with dummy bar) from the mould at a certain speed. To prevent the
solidified shell from cracking breakout and reduce the withdrawal
resistance of the mould, mould inner wall lubrication and up-down
reciprocating movement are required.
After pulling out from the mould, the casting billet shall be
cooled by spaying water, and this is called secondary cooling,
meanwhile casting billet liquid-core will be gradually solidified
by the secondary cooling.
The casting billet is continuously pulled out and molten steel is
continuously poured into the mould, forming into the continuous
casting process.
After passing through the billet withdrawing machine and
straightening machine (straightening is not required for vertical
type and horizontal type continuous casting), the casting billet
will be removed from dummy bar.
The completely solidified straight billet will be cut into required
size by cutting equipment, and transported to subsequent process by
conveying roller.
The equipment used for continuous casting steel production is
actually the complete set of mechanical equipment in the continuous
casting production line.
In the continuous casting production, one complete set of
continuous casting equipment that share with one ladle and capable
of one strand or multiple strand casting billet production is
called one set of CCM.
One set CCM can be of multiple units or single unit, the unit at
here means the independent driving system and work system in one
set of CCM.
For each set of CCM, the total quantity of the casting billet that
is casted at the same time is called CCM strand quantity.
If one set of CCM has only one unit and is capable of one casting
billet production, it is called one unit one strand; if one set of
CCM has one unit and is capable of more than two casting billets
production at the same time, it is called one unit multiple
strands; if one set of CCM has multiple units and capable of
multiple casting billet production, called multiple units multiple
strands.
