冷轧立式连退炉W型辐射管的结构优化

Structure Improvement Of W-Type Radiant Tube of Vertical Furnace in Cold Rolling Mill

W型辐射管是冷轧带钢连续退火工艺段常用的间接加热设备,一般使用寿命仅为三年。为了延长W型辐射管的使用寿命,现将辐射管的结构形式进行优化,由下吊挂式改为上搁置式,增加了辐射管的热变形自由度,可有效防止辐射管体的下垂、损坏,延长其使用年限。

W-Type radiant tube is a kind of indirect heating equipment commonly used in the continuous annealing process of cold rolling strip,Its service life is only three years. In order to prolong the service life of W-type radiant tube, the structure of the radiation tube is optimized from hang-up to upside-place to increase the heat deformation freedom degrees of the radiation tube, which can effectively prevent the radiation tube sagging, damaging and prolong its service life.
