摘要： A grid-shaped molding passage is formed in an outlet surface of the die body, and in an inlet surface on the opposite side plural independent supply passages are formed, which are opposite to intersecting portions of the molding passage and extend toward the outlet surface. A through hole is designed to communicate adjacent supply passages at a place that forms part of the partition wall between the supply passages and is in contact with the molding passage. This through hole takes the combined shape of a trapezoid with the width of the molding groove as its top side and the diameter of the supply passage as its maximum base side and a semicircle having the length of the base side as its diameter. This die may be used for molding catalysts or carriers, honeycomb-structured dry kneading agents or adsorbents, or organic fiber-containing ceramics and the like.

摘要： The die for moulding honeycomb structures has a main body with an inlet surface which is perforated by numbers of independent feed passages in matrix format to admit the raw material to be extrusion-moulded. The complimentary die mask has an outlet surface with moulding grooves corresponding to the inlet surface feed passages. The tops of throughbores which provide intercommunication for the feed passages are of semi-circular cross-section while their lower portions are cone-shaped, narrowing to the dia. of the moulding grooves.

摘要： Latticed molding grooves (2) are provided in an outlet surface (3) of a die body (7), and a plurality of independent feed passages (5), in the portions of an inlet surface (4) thereof, i.e. the surface opposite to the outlet surface (3), corresponding to the intersecting portions of the molding grooves (2) and extending toward the outlet surface (3). The adjacent feed passages (5) are communicated with one another via through bores (6) at the portions of partition walls of the feed passages (5) via which the feed passages (5) are communicated with the molding grooves (2). Each of these through bores (6) is formed of a combination of a cross-sectionally trapezoidal portion having a lower side 11-12 the length of which is equal to the width of the molding groove (2), and an upper side 13-14 the maximum length of which is equal to the diameter of a feed passage (5), and a cross-sectionally semicircular portion the diameter of which is equal to the length of the upper side 13-14.

摘要： PURPOSE:To produce porous ceramics having superior strength by mixing sinterable coarse particles with high fired particles, a pore forming agent an org. binder and by molding and sintering the resulting mixture. CONSTITUTION:20-80wt.% sinterable coarse particles (A) such as powder of potsherd are mixed with 5-80wt.% high fired particles (B) of 100-3,000mum particle size such as alumina particles, a pore forming agent (C) such as sawdust and an org. binder (D) such as PVA. The resulting mixture is molded and sintered at the sintering temp. (800-1,300 deg.C) of the component A.

摘要： PURPOSE:To eliminate generation of cracks, prevent leakage of fluid and reduce manufacturing man hours by a method wherein the element is formed by extrusion so that an extruded section obtains comb-teeth like configuration or multi-hole configuration in which polygonal holes re arrayed in one row. CONSTITUTION:Porcelain material is pulverized, mixed and spread, thereafter, is extruded by an extruder so that the extruded section obtains comb-teeth configuration of multi-hole configuration in which the polygonal holes are arrayed in one row. The element is formed by extrusion so as to arrange the comb-teeth like grooves or polygonal holes in parallel to the extruding direction thereof. The extruded form is dried at 30-120 deg.C for 6hr in the same manner as the manufacturing of normal porcelains and, subsequently, is calcined at 900-1700 deg.C to obtain a primary calcined product. During these processed, the base of the element is contracted. Thereafter, the calcined products are connected by the composition of glazing so that openings, neighboring in up-and-down direction and opened by extrusion, are intersected mutually with a given angle, then, they are calcined at 500-1700 deg.C again to obtain the intersecting elements. A low temperature inflating material, such as cordierite or spodumene, for example, or the material such as alumina, silicon carbide or the like are used in accordance with the purpose of the element to manufacture the element excellent in resistance to heat, resistance to abrasion or high heat conductivity in accordance with the usage thereof.
摘要翻译：目的：为了消除裂纹的产生，防止流体的泄漏，并通过挤压形成元件的方法减少制造人员的工作时间，使得挤压部分获得梳齿状构造或多孔构造，其中多孔被排列在一排构成：将瓷材粉碎，混合并铺展，然后通过挤出机挤出，使得挤出部分获得其中多孔形状排列成一排的多孔构造的梳齿构型。该元件通过挤出形成，以便将梳齿与凹槽或多边形孔平行于其挤压方向排列。将挤出形式以与正常陶瓷的制造相同的方式在30-120℃下干燥6小时，随后在900-1700℃下煅烧，得到初级煅烧产物。在这些处理过程中，元素的基底被收缩。此后，煅烧产物通过玻璃的组合物连接，使得沿上下方向相邻并且通过挤压打开的开口以给定的角度相互相交，然后再次在500-1700℃下煅烧以获得相交元件。根据元件的目的，使用例如堇青石或锂辉石等低温膨胀材料，或者诸如氧化铝，碳化硅等的材料来制造耐热性，耐磨性优异的元件或高导热率。
