本发明涉及轧钢技术领域，特别涉及一种热轧H型钢弯曲控制方法。本发明将H型钢轧制终轧道次做为平整道次，对成品轧件进行高温热矫成型，轧制道次中万能粗轧机、轧边机为空过机架，不参与轧制，万能精轧机的立辊压下率在3％‑5％之间，平辊压下率在2％‑5％之间，平辊轧制负荷为2000‑2500KN之间，立辊轧制负荷在2000‑3000KN之间，轧制速度为3‑8m/s之间。采用本发明生产的产品，有效消除了产品的弯曲缺陷问题，而且由于压下率的重新分配，间接提高了产品的机械性能，工艺实现简单，生产效率高,性能稳定，外形优良，尺寸精度高，产品质量提升效果显著。

The invention relates to the technical field of steel rolling, in particular to a bending control method for hot-rolled H-shaped steel. The H-shaped steel rolling last pass serves as temper pass, high-temperature heat correcting forming is conducted on a finished rolled piece, a universal rouging mill and an edging roll in the rolling pass are suspension racks and do not participate in rolling, the reduction rate of a vertical roller of a universal finishing mill ranges from 3% to 5%, the reduction rate of a flat roller of the universal finishing mill ranges from 2% to 5%, the rolling load of the flat roller ranges from 2,000 KN to 2,500 KN, the rolling load of the vertical roller ranges from 2,000 KN to 3,000 KN, and the rolling speed ranges from 3 m/s to 8 m/s. According to a product produced through the method, the problem about the bending defect of the product is effectively solved; meanwhile, due to reassignment of the reduction rate, the mechanical performance of the product is indirectly improved, technology achieving is easy, the production efficiency is high, and performance is stable; and the appearance is excellent, the size precision is high, and the product quality enhancing effect is obvious.
