Kinds of Pig Iron: casting pig iron Z14－Z34, steel-making
pig iron L08, nodular cast iron Q10－Q16.
 Beigang's pig iron enjoys
a great reputation with its long history. One trait of Beigan's ore,
low impurities content, with the ore, the highly pure pig iro in the
world can be produced. Beigan's casting pig iron and nodular pig iron
are the superior raw materials for producing casting iron pieces,
because of its low impurities content, fine flow of molten iron and
great spherodizing , our pig iron was called "Ginseng Iron"
which are widely marketed in Japan, Thailand, Indian and Hongkong,
Our pig iron are widely used in fields of auto manufacture, casting
for industry and civil use, precision casting, steel-making, weapon
and spaceflight etc.
Properties of Beigang's casting pig iron and nodular pig
iron:
Our casting pig iron and nodular pig iron under the name of "Beitai"
are the quality raw materials of complicated and superior casting
iron pieces. Low sulphur content, low phosphor centent, low content
of microelecments, ST=0.0675％, little spheroidization interference
effect, high mineral carbon spheroidization rate, fine toughness
are all its characteriscs. Our pig iron can met the production needs
of think wall of iron casting pieces, Comparing our pig iron with
other pig iron, the qualification rate is 5% up, some pig iron for
family use can increase 20%.
According to Beijing Iron & Steel Academy, Beigan's
pig iron has following traits:
1 Because the synthetic action coefficient of spheroidization pig
iron K1 is very small, the mineral carbon spheroidization rate is
as high as 85%.
2 The microelement content of pig iron is very low and stable, the
pearlite effect coefficient is low, which is avail to form ferrite
organization.
3 The iron pieces from beigang's pig iron characterized by its excellent
universal properties, especially toughness and plasticity (impact
value ak＝109.5j/cm2, extensibility d＝20.7％). undoutedly, our pig
iron is the superior raw materials for nodular casting iron.
4 The iron pieces from Beigang's pig iron is stable and has no distortion.
