The embodiments relate to a method for the production of a refractory metal component by casting. The method includes providing a slip that contains a powder including at least one refractory metal or a compound thereof, in addition to at least one binding agent. The method further includes processing the slip by casting, (e.g., film casting or slip casting), to form at least one slip coating, the slip being devoid of a metal binding agent. A component was produced by this method. The embodiments may be used, in particular, on X-ray tubes, accelerator targets, or fusion reactors, such as for a surface of an X-ray anode, or a wall of a fusion reactor.

Method and system for decorating a base ceramic article (CB) having a surface to be decorated. The decoration system comprises: a first printing assembly for applying a first layer of adhesive material on at least part of the surface; a digital depositing assembly for depositing a second layer comprising granular material or enamel atomized particles on the first layer to form an at least partially relief pattern on the surface; a detection assembly of such at least partially relief pattern; a second printing assembly, operable based on the data detected by the detection assembly, to form a defined image on the at least partially relief pattern; a dryer configured to dry the base ceramic article (CB) and arranged between the digital depositing assembly and the second printing assembly; and a firing kiln.

A machine for dry decoration of ceramic slabs or tiles, comprising: a support element (10), provided with a plurality of cavities (11) with a pre-established shape; a dispensing device (20), configured to deposit a pre-fixed amount of powder material inside one or more pre-established cavities (11); an unloading device (30), configured to move the cavities (11) from a loading position, in which they can receive the powder material from the dispensing device (20), to an unloading position, in which they can unload the powder material.

A slurry feed apparatus for depositing a slurry upon a moving forming web having a direction of travel, including: a headbox mounted transverse to the direction of travel of the moving web, having a back wall, sidewalls, a concave transverse front wall, an open top, and an open bottom for directing slurry onto the forming web; a moveable dam releasably attached to the back wall, a seal attached to a bottom wall of the dam; and a headbox support system extending from opposed the sidewalls. Also disclosed is a continuous process for depositing a uniform layer of a cementitious slurry containing reinforcing fibers from the headbox onto a traveling web.

The present invention relates to processes and apparatuses for producing fiber cement sheets as well as fiber cement sheets obtainable therewith. The processes according to the present invention at least comprise the steps of: (a) providing a cementitious slurry comprising fibers, (b) continuously discharging the slurry on an endless water-permeable transport belt, and (c) removing excess of water from the slurry through the water-permeable transport belt to form a fiber cement sheet with a predetermined thickness. By using a water-permeable transport belt for removing the excess of water from the fiber cement sheet, both the thickness and the density of the sheet can be accurately tuned, without resulting in a spring-back of the thickness of the sheet at the end of the production process. The present invention further relates to various uses of the fiber cement sheets obtainable by the processes of the invention in the building industry.

The invention relates to a conveyor line for the continuous production of drywall boards as well as a slurry distributing device which is used in this conveyor line. The distributing device is used for the uniform and low-speed flow distribution of slurries.

An apparatus for production of a gypsum product is provided which comprises a conveyer comprising a conveyer belt and means for rotating the conveyer belt; means for forming a gypsum product; and at least one laser scanner positioned over the conveyer belt at the location where the scanner scans at least one edge of the gypsum product which is at least partially set; and the laser scanner is in communication with a processor. Methods for forming a gypsum product with the apparatus are provided as well.

An apparatus including a first dispensing device configured to supply a first material to a conveyor belt of the main conveyor device in response to control by the computer processor, and a second dispensing device configured to supply a second material on top of the first material, while the first material is on the conveyor belt to form a combination comprised of at least the first and second materials, in response to control by the computer processor. The combination may be compressed by a first compression device in response to control by the computer processor. The compressed combination may be stirred by a first stirring device in response to control by the computer processor to form a first modified combination. The first modified combination may be compressed by a second compression device in response to control by the computer processor to form a compressed first modified combination.

A method for manufacturing ceramic articles is described comprising a step of feeding, during which at least two different ceramic powders are fed so as to obtain a strip of ceramic powders having at least a first zone and at least a second zone having a given shape; a step of compacting, during which the strip of ceramic powders is compacted so as to obtain a compacted layer of ceramic powders, which is expanded relative to the strip of ceramic powders; a step of determination, during which expansion of the layer of powders is determined; and a step of printing, during which a decoration having a modified shape based on the given expansion is applied on the surface of the compacted layer of ceramic powders.

[Object] To provide a building material manufacturing apparatus that is suitable for suppressing clogging of a screen that screens a building raw material. [Solution] A building material manufacturing apparatus X1 includes at least a screen part 10 and a cleaning mechanism part 40. The screen part 10 includes at least one screen sheet 12 that has an inclination and that has a screen mesh. The cleaning mechanism part 40 includes a scraping part 40a. When the apparatus operates in a building material manufacturing mode in which a building raw material M is supplied to the screen sheet 12 and the screen sheet 12 is performing a wave motion, the scraping part 40a is separated from the screen sheet 12, and, when the apparatus operates in a cleaning mode in which the building raw material M is not supplied to the screen sheet 12 and the screen sheet 12 is not performing a wave motion, the scraping part 40a rotates in contact with the screen sheet 12.
