PIG CASTING MACHINE

PIG CASTING MACHINE
No. 07-005
NAGATA ENGINEERING CO., LTD.

NAGATA’s Pig Casting Machine
We, Nagata Engineering Co., Ltd., had supplied a lot of Pig Casting
Machine to Steel Making Companies, Ferroalloy Companies and etc.
since 1956 including the era of Nagata Seisakusho Co., Ltd. Our Pig
Casting Machine is used widely to produce the pig iron or metal ingot.
We introduce to you the characteristics of this machine hereinafter.

Constitution of Pig Casting System
Specification of Equipment
Machine Body
1) Machine Head
The driving system is composed with
the set of variable speed controlled
motor, gear reducer and sprocket.
2) Machine Tail
Take-up device is provided on the tail sprocket shaft to give
appropriate tension to the link chain.
Also the Water Cooled Rail is equipped instead of the stationary rollers at
the pouring area to smooth the moulds running.

3) Stationary Roller & Link Chain
We are adopting the Stationary roller type.
This machine can obtain comparatively small power by this type, because
the link chains with the moulds run on the stationary rollers that are
fixed in regular distance.
4) Sticker Device
When the moulds reverse on the machine head, the almost of pig iron is
removed from the mould by lime coating.
In case that the pig iron remained in the mould, the pig iron is removed
by this device.

Scattered Iron Disposing Equipment
When the hot metal is poured in the mould through the casting trough, the
scattered iron occurs by the shock.
The scattered iron is received, and is pulled out from the machine by this
equipment.
Pig Cooling Water System
The pig iron in the mold is cooled by water spray or shower.
Normally, the circulating water from the pond is used as cooling water, and
the cooling zone is given for about 2/3 of machine length.

Mould Coating Equipment
In the case that the mould surface is not coated, the pig iron can not remove
from the mould.
Therefore, the mould surface is coated to remove the pig iron smoothly.
Normally, we are adopting the lime powder as coating material.
AGITATING TANK
POWDER LIME HOPPER
Spray tank
SLURRY PUMP FOR SPRAYING
Return
Slurry pump
P
Agitating tank
Mould Drying Equipment
This equipment is installed to dry the mould surface to prevent the explosion,
because the mould surface is getting wet by the lime slurry spraying.

Swing Pan Conveyor
This machine is used to carry the pig iron from the Pig Casting Machine to
the stock pile, and is very convenient device for the stock piling.
