摘要
结合棒材生产线设备布置情况，制定了大规格高精度热轧圆钢开发方案，通过严格控制加热炉各段温度和开轧温度，应用高压水除鳞技术，精确设计孔型系统，采用硬质合金轧辊和防划伤传送专用导槽等，张钢开发出Q235、45#、20#、弹簧圆钢等钢种Φ45～Φ60 mm热轧高精度圆钢，产品迅速批量生产，几何尺寸及力学性能均满足GB/T 702-2008标准要求。
Combining with the facility layout status of the bar production line, the development plan of large size and high precision hot rolled rounds was laid down. By strictly controlling furnace temperature of each section and start rolling temperature, applying high-pressure water descaling technology, precisely designing the pass system and adopting carbide rolls and special anti-scratch transfer guide grooves, Zhangdian Steel developed Φ45-Φ60 mm high precision hot rolled rounds of many steel grades such as Q235, 45 grade, 20 grade and spring steel. The products rapidly made batch production. The physical dimension and mechanical properties meet the needs of the Standard GB/T 702-2008.
