| Abstract: | In the paper,a mathematical model for the rises of temperature caused by the deformation and friction of web flange of the H-beam is established by using calculus of variation. At the same, time the drops of temperature caused by contacting and shuttle are also accounted. The formula calculating the universal rolling temperature of the H-beam is derived. The results tested on line show that all calculation method and computer program used are correct and practical. |
