    Abstract: A honeycomb extrusion die assembly (10) comprising a honeycomb extrusion die (701) and a forming plate (800) to block batch flow to at least a portion of a skin forming region. The honeycomb extrusion die (701) comprising a step cut discharge surface (758, 760) in the skin forming region and at least some slots (722) each with a divot (312) spaced toward a discharge surface (710) from a feedhole-slot intersection and a wide portion at the discharge surface (710) extending into the die body to the divot (312) to strengthen a peripheral region of a honeycomb extrudate in a reinforcement region, and a bulk nominal section corresponding to a bulk region of the honeycomb body.

    Abstract: Methods of firing a cordierite green body to form a fired cordierite body. The green body comprises cordierite-forming raw materials and organic material, the body having a core portion and a skin portion. The green body is pre-heated to a pre-heat temperature that is less than a thermal decomposition temperature of the organic material. The green body is maintained at the pre-heat temperature for a period of time sufficient to minimize a temperature differential between the core portion and the skin portion. The green body is heated to a low firing temperature in a firing atmosphere sufficient to reduce a content of the organic material and to substantially remove chemically bound water from hydrous alumina. The green body is heated to a high firing temperature in a firing atmosphere sufficient to reduce the content of the organic material prior to a substantial removal of chemically bound water from clay.

    Abstract translation: 焙烧堇青石生坯以形成烧堇青石体的方法。 生坯包括堇青石成形原料和有机材料，主体具有芯部分和皮肤部分。 将坯体预加热至低于有机材料的热分解温度的预热温度。 将生坯体保持在预热温度下足以使芯部分和皮肤部分之间的温度差最小化的时间。 在烧制气氛中将生坯体加热到低烧成温度，足以降低有机材料的含量并从水合氧化铝基本上除去化学结合的水。 在大量从粘土中除去化学结合水之前，将生坯在烧制气氛中加热至高烧成温度，足以降低有机材料的含量。
