HONEYCOMB STRUCTURE AND HONEYCOMB STRUCTURE PRODUCTION METHOD
To provide a honeycomb structure provided with an electrode layer excellent in the uniformity of a thickness.SOLUTION: A honeycomb structure production method according to an embodiment in this invention has: a molding step of extrusion-molding a molding material containing a ceramic raw material to obtain a honeycomb molded body; and a firing step of firing a honeycomb dried body obtained by drying the honeycomb molded body to obtain a honeycomb structure. The molding step includes supporting an outer circumferential face along an extending direction of cells of the cylindrical honeycomb molded body obtained by the extrusion molding by a pedestal so as to be conveyed. The pedestal has: a body part having a groove part along the extending direction of the cells; and a contact part arranged at the groove part of the body part and having an arc-shaped curved face contacted with the lower half of the honeycomb molded body. The contact part is composed of a material having a hardness of 74 N or less, and a difference between a diameter of the arc-shaped contact part and a diameter of a mold in the extrusion molding is 0.6 mm or less.SELECTED DRAWING: Figure 5A
【課題】厚みの均一性に優れた電極層を備えるハニカム構造体を提供すること。【解決手段】本発明の実施形態によるハニカム構造体の製造方法は、セラミック原料を含む成形材料を押出し成形してハニカム成形体を得る成形工程と、前記ハニカム成形体を乾燥させたハニカム乾燥体を焼成してハニカム構造体を得る焼成工程と、を有し、前記成形工程は、前記押出し成形によって得られる円筒状のハニカム成形体のセルが延びる方向に沿う外周面を受台で支持して搬送することを含み、前記受台は、前記セルが延びる方向に沿う溝部を有する本体部と、前記本体部の前記溝部に配置され前記ハニカム成形体の下半分に当接する円弧状の湾曲面を有する当接部と、を有し、前記当接部は、硬度７４Ｎ以下の材質で構成され、前記円弧状の当接部の径と前記押出し成形の金型の径との差は０．６ｍｍ以下である。【選択図】図５Ａ
