烘芯底板由于长期受热和冷却,极易断裂。笔者在某乡镇企业协助工作时,核企业原烘芯底板如图1所示。这种烘芯底板只烘芯2～3次即发生断裂。参考有关资料,我们设计了具有弹性筋的烘芯底板,结构如图2所示。烘芯底板加强筋的高度按附表数据选取。这种结构的烘芯底板,自1987年12月制成后,已进出窑烘芯近百次,未发现断裂现象,烘 Dry core floor due to long-term heating and cooling, easily broken. The author in a township enterprises to assist work, nuclear enterprises original bake floor shown in Figure 1. This drying core floor only baking core 2 to 3 times that is broken. Reference to the relevant information, we have designed a bake core floor with elastic ribs, the structure shown in Figure 2. Drying core floor stiffener height according to the schedule data selected. This structure of the core drying floor, made since December 1987, has been out of kiln baking core nearly a hundred times, did not find the phenomenon of fracture, drying
