一、概述目前,我国以角钢为主要产品的轧钢厂,为将冷床尾部的角钢成组地送给剪切机进行剪切,有的厂把剪切辊道面安装得低于冷床面,中间用坡道过渡,用斜面拨爪小车把一组角钢沿坡道推到剪切辊道上;有的厂把剪切辊道面与冷床面安装在同一水平面上,用平面推爪小车把一组角钢沿冷床面推到剪切辊道上。我厂在改造前就属于后一种形式,如图1所示, First, an overview At present, China’s angle iron as the main product of the rolling mill, the tail of the cold bed to the tail of the angle of the shears for cutting, and some plants to install the shear roller surface is lower than the cold bed , The middle of the ramp with the ramp dial car a group of angle along the ramp pushed to the shearing roller; some plants to cut the roller surface and the cold bed surface mounted on the same level, with a flat pawl car Push a set of angles along the cooling surface onto the sheer roller. Our factory belongs to the latter form before the transformation, as shown in Figure 1,
