【 摘 要 】

The analysis of the negative influence of the uniform heating of billets along the length in the continuous furnaces with a mechanized hearth on the work of heating furnaces, rolling mill and the quality of metal products is given. The influence of the non-uniformity of heating on metal loss is investigated. Based on the experimental data analysis of temperatures measurements of billets surface heated in the walking-hearth furnace, a statistical analysis was carried out and the equation of regression of the temperature distribution along the length of the billet was obtained using the least squares method. It is established that an increase in the non-uniformity of surface billet heating leads to an increase in the metal loss, and this dependence has a nonlinear character.
