We present the analysis of the designs of furnace rollers for various temperatures of the furnace and the main defects acquired in the process of operation. As the main cause of replacements of the rollers, we can mention their inadmissible residual deflections. On the basis of the comparative analysis of the strength of furnace rollers, it is shown that the conventional yield strength at the operating temperature plays the role of strength criterion for the material of their barrels. It is shown that the application of uncooled furnace rollers made of heat-resistant steels enables us to decrease metal consumption and reduce operating costs.

降低轧机辊道金属消耗量和运行成本

介绍了针对不同炉温的炉辊设计分析，以及在运行过程中发现的主要缺陷。作为更换辊子的主要原因，我们可以提到它们不允许的残余挠度。通过对炉辊强度的对比分析，表明工作温度下的常规屈服强度对其筒体材料起到了强度判据的作用。结果表明，应用由耐热钢制成的非冷却炉辊使我们能够减少金属消耗并降低运营成本。
