    摘要： The inorganic fiber molded body of the present invention is characterized in that the molded body has an extremely light weight, and is free from problems such as scattering of fibers and particulate matters from a surface thereof and environmental pollution such as generation of harmful gases. In addition, the present invention provides an inorganic fiber molded body that is excellent in not only thermal shock resistance and mechanical shock resistance but also a high-speed wind erosion resistance, well-balanced in properties and can be used in the applications of various heat-insulating materials. The present invention relates to an inorganic fiber molded body comprising inorganic fibers and inorganic binder particles and having at least one set of a high-fiber density region and a low-fiber density region, in which a ratio of a content of the binder particles in the high-fiber density region to a content of the binder particles in the low-fiber density region as measured by a predetermined method is 0.5:1 to 5:1; and a number-average particle diameter and the number of the inorganic binder particles on an outermost surface of the molded body as measured by a predetermined method are 20 to 35 µ m and less than 15, respectively.

    摘要： Refractory coating for pipes, cooled by water or other cooling fluids, forming the structure of furnaces for heating bars, pipes or steel sheets. Said coating is made of a metallic structure (steel sheet or wire net) and an additived, prefabricated concrete, characterised by a low thermal conductivity. Said additive can be similar to that one described and claimed in the Italian patent No. 01243638. In order to further reduce the thermal coefficient, between the steel sheet and the concrete, a thin layer of ceramic fiber and/or other suitable material (e.g. insulating concreted can be inserted. Finally, the invention, in different practice examples, also solves the problem of the coating anchorage to the pipes.

    摘要： The present invention relates to a furnace for very high working temperatures, and to a method of operating such a furnace. This high temperature - above 1800°C - is achieved by using resistor elements of stabilized zirconium dioxide. An electrically heated furnace according to the invention includes an inner furnace chamber provided with resistor elements of stabilized zirconium dioxide, and an outer furnace chamber in which further resistor elements that can work at temperatures above 1800°C in an oxygen-containing atmosphere are provided. The outer resistor elements are conveniently of a molybdenum silicide type, for instance elements marketed under the designation KANTHAL Super. Those walls that delimit the inner furnace chamber are comprised of zirconium dioxide material or some other suitable material that has a low specific thermal conductivity and capable of withstanding the high working temperature and the occurrent temperature swings. The outer chamber, which completely surrounds the inner chamber, is delimited to the surroundings by conventional walls insulated, e.g., with ceramic fibres and/or high-temperature durable brick.
