1. 前言回顾钢轨的生产历史,就会看出钢轨生产每一次大的进步都与炼钢技术的提高和某些重大发明密切相关.1825年史蒂文森发明蒸汽机车的同时就出现了铁路,起初铁路是用木质轨铺设的,后来用生铁和熟铁轨,十九世纪中期酸性转炉的出现,开始采用轧制法生产钢轨,钢轨的使用寿命比铸铁轨长十倍左右,托马斯转炉的出现为采用含磷的生铁炼制钢轨钢开辟了途径.从本世纪开始,
1. Preface Looking back at the history of rail production, we see that every major advance in rail production is closely linked to the advancement of steel-making technology and to some major inventions. In 1825 Stevenson invented the steam locomotive with the simultaneous appearance of railways, At first, the railway was laid with wooden rails, and later with pig iron and cooked rails, the mid-nineteenth century, the emergence of acidic converter, began to produce rail rolling method, rail life ten times longer than cast iron rail, Thomas converter appeared Using phosphorus pig iron refining rail steel has opened the way from the beginning of this century,
