1、发展概况初轧机的历史比较悠久,第一台初轧机于1866年建成,迄今已有将近110年的历史。在1866～1945年期间所建的初轧机,轧辊直径都在1米以下,其中有不少是小型的三辊式轧机,轧制2～10吨的钢锭,每台轧机的年产量为百万吨左右,全部人工操作,属于初轧机发展阶段中的初期,也有人称为“第一代初轧机”。 1945～1960年属于初轧机发展阶段的中期,这个期间所建的初轧机称“第二代初轧
1, the development of the history of the first mill has a long history, the first mill completed in 1866, so far, nearly 110 years of history. During the period from 1866 to 1945, the initial mill was built with roll diameters of less than 1 meter, many of them small three-roll mills that rolled 2 to 10 tons of steel ingots each with an annual production of 1 million Ton, all the manual operation, belonging to the initial stage of the early stage of rolling mill, also known as “the first generation of early rolling mill.” 1945 to 1960 belonged to the middle stage of the development stage of the early rolling mill, the initial rolling mill built during this period called "the second generation of early rolling
