我厂为莱钢总厂炼钢厂制造的长轴,是连铸车间钢坯移送机的重要组成部件之一。其结构特点是轴长、立板高、焊缝不对称(如图所示),因此,悍接过程中易产生两种情况的变形:一是φ351mm管子的弯曲变形;二是φ351mm管子与δ=40mm立板之间的角度变形。为保证φ351管子的直线度及其与立板的垂直度,在制造过程中我们采取下列防变形措施,取得了满意的效果。
I plant for the steel plant in Laiwu Steel Plant long axis, continuous casting shop is one of the important components of billet transfer machine. Its structure is characterized by axial length, vertical plate, weld asymmetry (as shown), therefore, easy to produce during the two-way deformation met: First, φ351mm pipe bending deformation; Second φ351mm pipe and δ = 40mm angle between the deformation plate. In order to ensure the straightness of φ351 pipe and its verticality with the vertical plate, we take the following anti-deformation measures in the manufacturing process and achieved satisfactory results.
