在过去五十年中制造的许多大型型钢轧机采用传统的轧机形式,即1架辊身长度不超过2700mm的粗轧机;3～5架横列式布置的二辊成型轧机。传统的用于生产工字钢、槽钢、钢轨、钢板桩、角钢、方钢等的轧机机组,生产能力约为40×14~4t,其布置如图1所示。 Many of the large section mills that have been manufactured in the last 50 years are in the traditional mill form, namely a roughing mill with a barrel length of up to 2,700 mm; and a 3 to 5 two-roll mill with a horizontal row. The traditional mill for the production of I-beam, channel steel, rail, sheet pile, angle steel, square steel, the production capacity of about 40 × 14 ~ 4t, the layout shown in Figure 1.
