我厂生产的桥梁I形、T形杆件,由于焊接变形,平直度差5～15毫米。过去靠人工校正,效率低、质量差、劳动强度大,满足不了铁路桥梁发展的需要。尤其是我厂承担的援外产品,根据设计要求制造的I形杆件,用原来的老办法根本无法校正调直。面对这种形势,钢梁车间立即组成了“三结合”革新小组,力争在援外桥梁投产之前攻破这道难关,做出大型钢结构I形、T形杆件校正机。“三结合”革新小组在“鞍钢宪法”光辉旗帜的指引下,奋发图强、自力更生,以顽强的革命精神克服了技术、设备上的困难,自行设计、制造成功大型结构钢I形、T形杆件
I plant the bridge I-shaped, T-bar, due to welding deformation, the straightness difference of 5 to 15 mm. In the past by manual correction, low efficiency, poor quality, labor-intensive, can not meet the needs of the development of railway bridges. In particular, I plant foreign aid products, according to the design requirements of the I-shaped rod, with the original old method simply can not be corrected. Faced with this situation, steel beam workshop immediately formed a “triple combination” innovation team, and strive to break the barrier before the commissioning of foreign aid bridge to make large-scale steel I-shaped, T-beam correction machine. Under the guidance of the glorious banner of “Anshan Iron and Steel” Constitution, the “Three-in-One” Innovation Team has made every effort to overcome difficulties in technology and equipment with a tenacious revolutionary spirit and designed and manufactured the successful large structural steel I-shaped and T-shaped bars
