摘要
为有效利用热源驱动对轧辊进行辊形柔性调控并实现轴向温控,提出以电子温控片为内源驱动的辊形电子温控技术。建立了辊形电子温控全过程有限元模型,并在辊形电子温控实验平台上进行了验证。依托该模型,研究了辊形电子温控过程中TEC参数、TEC温控模式及组合模式对电子温控辊形的影响。结果表明,热端温控模式可提升电子温控轧辊的辊形电子温控能力;冷端温控模式可减弱电子温控过程中热量的轴向传递且能够小幅提升辊形电子温控能力。二者的调控能力能够随TEC参数的提升而增大。组合模式下,中间TEC参数对电子温控轧辊辊凸度的影响高于边部TEC参数。
To effectively use the heat source drive to carry out the flexible control of roll profile and realize the axial temperature control, the electronic temperature control technology of roll profile with thermal electric cooler(TEC) chip as the inner source driver was proposed. The finite element model of the whole process of electronic temperature control of roll profile was established and verified on the experimental platform of electronic temperature control of roll profile. Based on the model, the effects of TEC parameters, TEC temperature control mode and combination mode on the electronic temperature control of roll profile were studied. The results show that the hot end temperature control mode can improve the electronic temperature control ability of roll profile of electronic temperature control roll. The cold end temperature control mode can weaken the axial heat transfer in the electronic temperature control process and slightly improve the electronic temperature control ability of roller shape. The control ability of both can increase with the increase of TEC parameters. In combination mode, the influence of middle TEC parameters on roll crown of electronic temperature control of roll profile is higher than that of side TEC parameters.
