    • A process for firing ceramic honeycomb structural bodies at a certain temperature in a given atmosphere is disclosed. The ceramic honeycomb structural bodies are fired, while a gas having a temperature equal to that of an atomsphere surrounding the exterior of the ceramic honeycomb structural bodies is forcedly passed through holes of the ceramic honeycomb structural bodies. By this firing process, a pore-forming agent and/or a shaping aid admixed in the ceramic honeycomb structural bodies can effectively be burnt away and the entire honeycomb structural bodies can uniformly be fired. Thus, fired ceramic honeycomb structural body having desired dimensions can be obtained in a shortened firing time.
    • 公开了一种在给定气氛中在一定温度下焙烧陶瓷蜂窝结构体的方法。 陶瓷蜂窝结构体被烧制,而具有与陶瓷蜂窝结构体外部的原子层相同的温度的气体被强制地通过陶瓷蜂窝结构体的孔。 通过该烧成工序,能够有效地将陶瓷蜂窝结构体中的成孔剂和/或成形助剂混合,能够均匀地烧结蜂窝结构体整体。 因此,可以在缩短的烧制时间内获得具有所需尺寸的烧制陶瓷蜂窝结构体。

    • A method for firing a ceramic honeycomb structure by a single furnace at a predetermined temperature in a predetermined atmosphere, while controlling combustion of a burner means for heating the ceramic honeycomb structure from the outside thereof. To this end, temperatures at the inside and outside portions of the ceramic honeycomb structure are detected, and the outside temperature thereof is regulated relative to the inside temperature thereof, based on the detected temperatures. The method ensures stable firing to produce a high-quality ceramic honeycomb structure, in which a pore-forming agent is uniformly burnt throughout the inside and outside of the product and the difference in the diameter of fine holes between those inside and those outside thereof is minimized so as to eliminate occurrence of cracks within and at end portions of the ceramic honeycomb structure.
    • 一种在预定的气氛中,在预定温度下通过单个炉烧制陶瓷蜂窝结构体的方法,同时控制用于从其外部加热陶瓷蜂窝结构体的燃烧器装置的燃烧。 为此,基于检测到的温度,检测陶瓷蜂窝结构体的内部和外部的温度,并且其外部温度相对于其内部温度被调节。 该方法确保稳定的焙烧以产生高品质的陶瓷蜂窝结构,其中造孔剂在产品的内部和外部均匀地燃烧,并且内部和外部之间的细孔的直径差为 最小化以消除陶瓷蜂窝结构体内部和端部的裂纹的发生。
