摘要： Disclosed is a bonding structure between a nozzle body of a continuous casting nozzle and a refractory sleeve inserted into the nozzle body, wherein the refractory sleeve contains 20 mass% or more of CaO. An adhesive including a mixture of a refractory aggregate and a binder is applied to a joint zone defined in either one of at least a portion of the outer peripheral surface of the refractory sleeve and at least a portion of the inner surface of the hollowed nozzle to which the refractory sleeve is attached, or between the inner surface of the nozzle body and the outer peripheral surface of the refractory sleeve inserted into the nozzle body. The adhesive is adjusted to have a porosity in the range of 15 to 90% after dried in the joint zone. The bonding structure has a function of relaxing a thermal stress due to exponential expansion of the refractory sleeve caused by molten steel flowing into an inner hole of the nozzle during use, so as to prevent the detachment of the refractory sleeve and adverse affects on the nozzle body due to thermal expansion of the refractory sleeve.
摘要翻译：本发明提供一种连续铸造用喷嘴的喷嘴体与插入到喷嘴体内的耐火套筒之间的接合结构，其中，耐火套筒含有20质量％以上的CaO。将包括耐火骨料和粘合剂的混合物的粘合剂施加到限定在耐火套筒的外周表面的至少一部分中的任一个中的接合区域和中空喷嘴的内表面的至少一部分，耐火套筒连接在其上，或者在喷嘴体的内表面与插入喷嘴体中的耐火套筒的外周表面之间。在接合区中干燥之后，调节粘合剂的孔隙率为15-90％。该粘结结构具有缓解由于在使用过程中钢水流入喷嘴的内孔而引起的耐火套管的指数膨胀所引起的热应力的功能，从而防止耐火套筒的脱落和对喷嘴的不利影响由于耐火套筒的热膨胀导致的物体。
