热矫形是矫正钢梁变形的常用方法,但它引起的残余应力会对钢梁的承载能力产生不利影响,甚至造成恶性事故。本文就此问题展开了讨论,并对热矫形温度的控制、热矫形后的钢梁加载使用问题提出了建议。
Hot orthopedic is a common method to correct the deformation of steel beam. However, the residual stress caused by it will adversely affect the carrying capacity of the steel beam and even cause a serious accident. This article discusses this issue, and puts forward suggestions on the control of hot orthodontic temperature and the loading and unloading of hot-rolled steel beam.
