Description
本实用新型涉及冷轧退火炉工艺设备技术领域，具体涉及带钢连续退火炉的隔热防护装置。The utility model relates to the technical field of cold rolling annealing furnace process equipment, in particular to a heat insulation protection device for a continuous annealing furnace for strip steel.
当前热处理炉（特别是硅钢生产冷轧退火炉领域）采用炉内辊道输送带钢，炉辊位于炉内，两端安装在炉墙上：先要在炉墙内的耐材上设计开孔，再在炉墙开孔处焊接安装板，用于安装炉辊轴承座；高温铝砖与炉辊之间的间隙的最小处为10mm；在靠近炉墙处的高温铝砖与炉辊之间还设有一道高温防火圈。其中高温铝砖与防火圈分别形成第一道隔温（阻挡绝大部分热气流）与第二道隔温（进一步缩小热流间隙）。这种设计，高温铝砖与炉辊之间的间隙仍较大，炉内的高温气体容易沿着炉辊砖与炉辊之间的间隙向轴承座扩散，轴承座和轴承温度较高，容易老化，且温度透过炉砖和炉辊之间的缝隙蔓延而出，不仅影响退火炉内的温度保持，且影响炉辊下方工人的工作。Current heat treatment furnaces (especially in the field of cold-rolling annealing furnaces for silicon steel production) use roller conveyor belts in the furnace.
