人类社会的发展在经历了石器时代、铜—青铜时代之后,大约在公元前1000年进入了铁器时代。现代大规模炼钢方法出现于19世纪中叶。英国人亨利·贝塞麦于1856年获得可以使生产钢的成本减少到原来的七分之一的空气转炉炼钢法专利,以及稍后利用带蓄热室的火焰炉生产钢水的平炉炼钢法的问世,标志着炼钢工业大生产的开端和从“铁时代”向“钢时代”的过渡。 钢铁具有强度高、硬度大、易于进行塑性加工、磁性好、耐腐蚀以及便于回收从而有利于节约资源和生态环境等诸多优良性能,兼之
The development of human society, after going through the Stone Age, the Bronze Age, entered the Iron Age about 1000 BC. Modern large-scale steelmaking methods appeared in the mid-19th century. The British Henry Betsey was granted an air-conditioner steelmaking patent in 1856 that reduced the cost of producing steel by a factor of seven, and later flat-rolled it to produce molten steel using a furnace with a regenerator The advent of the law marks the beginning of mass production in the steelmaking industry and the transition from the “iron age” to the “steel age.” Iron and steel with high strength, hardness, easy plastic processing, magnetic, corrosion-resistant and easy recycling so as to save resources and ecological environment, and many other good performance, both
