Description

Обычно изготовление карборундовых огнеупоров производитс  обжигом предварительно сформованного сырца из смеси карборундовых зерен различной крупности и огнеупорной пластичной глины.Typically, the manufacture of carborundum refractories is carried out by burning a preformed raw material from a mixture of carborundum grains of various sizes and refractory plastic clay.

Получаемые таким способом издели  отличаютс  невысокой температурой начала разм гчени  под нагрузкой , не превосход щей 1500°.The products obtained in this way are characterized by a low temperature for the onset of softening under a load not exceeding 1500 °.

Предложены способы повышени  температуры начала разм гчени  путем добавки к карборунду глины и кварца.Methods have been proposed for raising the temperature of the onset of softening by adding clay and quartz to carborundum.

Однако, по имеющимс  в литературе данным, подобным способом хот  и достигаетс  некоторое повышение температуры начала разм гчени , но при этом  вл етс  необходимым производить обжиг изделий при температуре , близкой к 1500.However, according to the data available in the literature, in a similar way, although some increase in the softening onset temperature is achieved, it is also necessary to bake the products at a temperature close to 1500.

/Автором установлено, что можно производить изготовление карборундовых огнеупорных изделий не на глинистой или кварцеглинистой св зке, а на кварцеизвестковой, ввод  в карборундовую шихту тонко дисперсную смесь кварца и окиси кальци . Применив подобную шихту, автор (по проведенным им работам) получил/ The author has found that it is possible to manufacture carborundum refractory products not on a clay or quartz – clay bond, but on a quartz-limestone product, introducing a finely dispersed mixture of quartz and calcium oxide into the carborundum mixture. Applying a similar charge, the author (for his work) received

Дл  придани  прочности сухому сырцу необходима добавка к шихте какого-либо в жущего, как например, сульфитного щелока, декстрина, мелассы и т. п.In order to give strength to the dry raw, an additive to the batch of some kind of binder, such as sulfite liquor, dextrin, molasses, etc., is necessary.

Качество полученных карборундовых изделий, как видно из приведенных выше показателей, высокое. При работе по предлагаемому способу в виде кварцевой составл ющей могут быть применены соответствующего качества кварциты, кварцевые пески, жильный кварц, песчаники и т. п.The quality of the obtained carborundum products, as can be seen from the above indicators, is high. When working on the proposed method in the form of a quartz component, quartzites, quartz sand, vein quartz, sandstone, etc. can be used with appropriate quality.
