铁 (Fe); 矫直 (【技】铁：元素符号 Fe, 银白色金属，在元素周期表中属 VIII 族，原子序数26。纯铁的延展性和磁性良好，易氧化，红热时容易使水分解产生氢；能溶解于稀盐酸、稀硫酸和稀硝酸，但不溶解于浓硫酸。高炉炼铁是最主要的炼铁方法，其他尚有直接还原炼铁法、熔融还原炼铁法等。铁通常分为生铁、熟铁、纯铁、海绵铁等。: During its descent in the blast furnace the iron absorbs a number of impurities from the coke, ore, and limestone, so that the pool of iron at the bottom of the furnace contains about 3 to 5 per cent carbon, about 1 per cent manganese, up to 3 per cent silicon, and usually a small amount of sulphur. 铁在高炉内下降的过程中从焦炭、矿石和石灰石中吸收了一些杂质，因此在炉底的铁水熔池中含有约3-5%的碳，约 1% 的锰和高达3%的硅，通常还含有少量的硫。) |
