Refined pig iron

中文百科

生铁 Pig iron

(重定向自Refined pig iron)

生铁是碳的质量分数超过2%,并且其他元素的含量不超过表1中所规定的极限值的铁-碳合金。

a 含量比该极限值高的材料是铁合金。

b 凡规定有最低含量或者含量超过表2注中段落4)所规定的下限值的元素,按表2注重段落3)和4)的规定,均为“其他合金元素”(C、Si、Mn、P、Cr除外)。

b 对该含量范围再进行细化,通常可将该类生铁产品进一步分成不同的等级。

c 根据冶炼生铁所使用的原料不同,生铁冢可能会含有不属于第(4)至第(8)栏所表示的其他元素,对这些元素未规定限定值。这些元素的质量分数有可能达到0.5%,供需双方可协商其限定值,但这些元素不用于对生铁的分类。

Pig iron 生铁

(重定向自Refined pig iron)
Pig iron of a type used to make ductile iron, stored in a bin
Casting pig iron, Iroquois smelter, Chicago, between 1890 and 1901.

Pig iron is the intermediate product of smelting iron ore. It is the molten iron from the blast furnace, which is a large and cylinder-shaped furnace charged with iron ore, coke, and limestone. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content, typically 3.5–4.5%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.
