摘　　要：从轧材原料、加热工艺、开坯工艺、设备因素等几个方面分析了H型钢轧制侧弯的原因。认为轧材原料和开坯工艺对H型钢轧制侧弯影响较小,加热工艺和开坯设备因素是H型钢轧制侧弯的主要原因。对轧制工艺、设备维修标准、轧材原料的质量等进行了改进。解决了H型钢轧制侧弯问题,实现了开坯轧制影响率为零的目标。It is analyzed the reason for the side bending of H sections in rolling from aspects： raw material, heating process,breakdown process,equipments. It is considered that the raw material and breakdown process have a little influence,whereas other two are the main factors. The rolling process and equipment maintenance standard are improved,and the defects are solved.
