High-precision hot-rolled U-shaped steel
The invention discloses high-precision hot-rolled U-shaped steel, and belongs to the technical field of hot-rolled U-shaped steel. The high-precision hot-rolled U-shaped steel is formed by rolling heated steel at the temperature higher than the recrystallization temperature and specifically comprises a bottom plate and leg edges, and the leg edges are fixedly arranged on the two sides of the bottom plate; grooves are formed in the top ends of the leg edges on the two sides through planing and milling, and truncated edges are reserved on the sides, not provided with the grooves, of the leg edges in the thickness direction. The U-shaped steel manufactured through the method has the advantages of being high in manufacturing precision, standard in specification, small in error size, easy to achieve small deformation, tight in connection and the like. The cutting procedure in a steel structure processing factory is reduced, the material loss is reduced, the processing material and labor input cost is reduced, and the processing environment pollution is reduced.
本发明公开了一种高精度热轧U型钢，属于热轧U型钢技术领域。本发明所提出的一种高精度热轧U型钢，由钢材通过加热后在再结晶温度以上轧制而成，具体包括有底板和腿部边，所述腿部边固设在底板两侧；两侧所述腿部边的顶端通过刨铣加工开设有坡口，所述腿部边沿厚度方向未开所述坡口一侧留设有钝边。本发明制作的U型钢具有制作精度高、规格标准化、误差尺寸小、容易实现小变形、紧密连接等优点。减少了在钢结构加工厂的切割工序，减少了材料损耗量，降低加工材料与人工投入成本，减少加工环境污染。
