Description
УНИВЕРСАЛЬНАЯ ОГНЕУПОРНАЯ КРЕПЕЖНАЯ ШПИЛЬКА UNIVERSAL FIRE-RESISTANT FASTING PIN
Область техники Technical field
Изобретение относится к области машиностроения, а именно - к крепежным средствам, например, болтам, шпилькам, винтам и другим стержневым крепежным элементам. The invention relates to the field of mechanical engineering, namely, to fastening means, for example, bolts, studs, screws and other rod fasteners.

Известен ряд крепежных огнеупорных шпилек (анкеров) производства английской фирмы Nelson ("Nelson® ",Bolzenschweiss- Technik Gmbh & Со.КО(Германия), http://nelsonua.com/component , выполняемых из специальных сталей с кольцом, привариваемым к шпильке специальным сварочным прибором в процессе монтажа футеровки (огнеупорные анкера "Nelson", каталог, с. 3-9, http://steeltradeteam.com/). A number of fastening refractory studs (anchors) are known produced by the English company Nelson ("Nelson®", Bolzenschweiss-Technik Gmbh & Co. Co. (Germany), http://nelsonua.com/component, made of special steels with a ring welded to the stud a special welding tool during the installation of the lining (Nelson fireproof anchors, catalog, p. 3-9, http://steeltradeteam.com/).
Недостатками данного изобретения являются жесткое сварное соединение шпильки с кольцом, что ведет к ослаблению крепежного соединения вследствие большего теплового расширения металла шпильки по сравнению с тепловым расширением керамики футеровки, разрушение жесткой футеровки, вызванное большей прочностью металла шпильки, чем прочностью керамической футеровки. При этом углубление металлической шпильки в материал футеровки и наличие металла ведет к образованию теплового шунта с потерей энергии во внешнюю среду. The disadvantages of this invention are a rigid welded connection of the stud with the ring, which leads to a weakening of the fastening due to the greater thermal expansion of the metal of the stud compared with the thermal expansion of the ceramic lining, the destruction of the hard lining caused by the greater strength of the metal of the stud than the strength of the ceramic lining. In this case, the deepening of the metal stud into the lining material and the presence of metal leads to the formation of a thermal shunt with a loss of energy into the external environment.

Раскрытие изобретения Disclosure of invention
Задача изобретения - создание конструкции универсальной огнеупорной крепежной шпильки для соединения внутренней поверхности футеровки печи с внешним каркасом, способной демпфировать тепловое расширение жестких и мягких материалов футеровок для печей различного вида нагрева. The objective of the invention is the creation of a universal refractory fastening stud for connecting the inner surface of the lining of the furnace with an external frame that can dampen the thermal expansion of hard and soft lining materials for furnaces of various types of heating.
Технический результат - повышение прочности универсальной огнеупорной крепежной шпильки и соединения внутренней поверхности футеровки печи с внешним каркасом. EFFECT: increased strength of a universal refractory fastening pin and connection of the inner surface of the furnace lining with the external frame.
Универсальная огнеупорная крепежная шпилька выполнена составной - керамическая часть шпильки выполнена из огнеупорного фосфатного бетона в виде цилиндра с полусферической головкой. Металлическая часть выполнена в виде резьбовой шпильки, залитой в керамическую часть в процессе изготовления. На металлической части расположена тарельчатая пружина с гайкой - «барашек» для крепления шпильки к несущему каркасу печи. The universal refractory mounting pin is made integral - the ceramic part of the pin is made of refractory phosphate concrete in the form of a cylinder with a hemispherical head. The metal part is made in the form of a threaded rod, poured into the ceramic part during the manufacturing process. On the metal part there is a disk spring with a nut - a “lamb” for fastening the studs to the supporting frame of the furnace.
Фиг. 1 - универсальная огнеупорная крепежная шпилька. FIG. 1 - universal refractory mounting pin.
Фиг.2 - крепление универсальной огнеупорной крепежной шпильки, разрез. Figure 2 - mount universal refractory mounting studs, section.
Универсальная огнеупорная крепежная шпилька выполнена составной, с одной стороны из огнеупорного фосфатного бетона в виде цилиндра 1 (Фиг.1) с полусферической головкой 2 и с другой стороны, встроенной в нее металлической резьбовой шпилькой 3, на которую надета тарельчатая пружина 4 с гайкой - «барашек» 5 для крепления
универсальной огнеупорной крепежной шпильки к несущему каркасу 6 (Фиг.2) футеровки 7 печи. The universal refractory fastening pin is made integral, on the one hand, from refractory phosphate concrete in the form of a cylinder 1 (Fig. 1) with a hemispherical head 2 and, on the other hand, a metal threaded pin 3 embedded in it, on which a disk spring 4 with a nut is put on - “ lamb »5 for mounting universal refractory fastening studs to the supporting frame 6 (Figure 2) of the furnace lining 7.
Демпфирование различных тепловых расширений футеровки печи, керамической и металлической частей универсальной огнеупорной крепежной шпильки осуществляется следующим образом: - полусферическая головка керамической части универсальной огнеупорной крепежной шпильки требуемого диаметра позволяет осуществить плотное соединение с футеровкой, в то же время, обеспечивает универсальной огнеупорной крепежной шпильке прецессию относительно осевой линии при большем тепловом расширении материала футеровки, чем тепловое расширение керамической части универсальной огнеупорной крепежной шпильки; осевое расширение керамической и металлической частей универсальной огнеупорной крепежной шпильки демпфируется тарельчатой пружиной с требуемыми характеристиками, обеспечивая необходимую прочность и плотность всего крепежного соединения; Damping of various thermal expansions of the furnace lining, ceramic and metal parts of the universal refractory fastening pin is carried out as follows: - the hemispherical head of the ceramic part of the universal refractory fastening pin of the required diameter allows tight connection with the lining, at the same time, provides a universal axial refractory fixing pin with a precession relative to the axial lines with greater thermal expansion of the lining material than thermal expansion of ceramic part of the universal refractory fastening stud; axial expansion of the ceramic and metal parts of the universal refractory fastening pin is damped by a Belleville spring with the required characteristics, providing the necessary strength and density of the entire fastening connection;
- длина керамической части универсальной огнеупорной крепежной шпильки определяется назначением печи, ее размерами, температурой эксплуатации; - the length of the ceramic part of the universal refractory fastening pin is determined by the purpose of the furnace, its size, operating temperature;
- длина металлической части, залитой в керамическую часть универсальной огнеупорной крепежной шпильки, определяется назначением печи, ее размерами, температурой эксплуатации; - the length of the metal part cast into the ceramic part of the universal refractory fastening pin is determined by the purpose of the furnace, its dimensions, and operating temperature;
- при выполнении этих условий керамическая часть универсальной огнеупорной крепежной шпильки выполняет функцию футеровки и не выступает тепловым шунтом. - when these conditions are met, the ceramic part of the universal refractory fastening pin performs the function of a lining and does not act as a thermal shunt.
При сборке тепловых агрегатов, в том числе печей различного вида нагрева, основную трудность представляет собой крепление огнеупорной футеровки к металлическому каркасу печи, вызванную различными коэффициентами теплового расширения участвующих в
конструкции материалов. При этом жесткая керамическая футеровка (формованные кирпичи, плиты и т.п.) требуют прочных и гибких крепежных элементов, тогда как мягкая керамическая футеровка (изделия из волокнистых материалов) требует крепежные элементы с большой опорной поверхностью. When assembling thermal units, including furnaces of various types of heating, the main difficulty is the fastening of the refractory lining to the metal frame of the furnace, caused by different coefficients of thermal expansion involved in construction materials. In this case, rigid ceramic lining (molded bricks, plates, etc.) require strong and flexible fasteners, while soft ceramic lining (products from fibrous materials) require fasteners with a large supporting surface.
Созданная конструкция универсальной огнеупорной крепежной шпильки способна демпфировать тепловое расширение, как жестких материалов, так и мягких волокнистых материалов футеровок для печей различного нагрева. Она обладает простотой установки и/или замены в процессе эксплуатации и не требует специальных устройств или операций для ее применения. The created design of a universal refractory fastening pin is capable of damping the thermal expansion of both hard materials and soft fibrous lining materials for furnaces of various heating. It has ease of installation and / or replacement during operation and does not require special devices or operations for its use.
