摘要

在有隔热衬里的风口风道内注入天然气的方式会影响衬里内热应力的分布和大小。对通过法兰孔注入天然气的风口构件的热应力状态进行了计算分析，结果表明：内衬端采用减小内径的法兰保护时热应力最大，内衬端采用环保护时热应力最小。

Methods of reducing the thermal stresses in the heat-insulation lining of blast-furnace tuyere with natural gas supplied through flange holes

The method of injecting natural gas into the air passage of a tuyere with a heat-insulation lining influences the distribution and magnitude of thermal stresses within the lining. A computational analysis of the thermal stress state of tuyere components with natural gas injected through the flange holes revealed that the thermal stresses are maximum when the lining end is protected by a flange with inner diameter reduced on the lining side, whereas they are minimum when the lining end is protected by a ring.
