Description

порошок, представл ющий co6ofi А120з-5102. Температура его плавлени  2089°К. Силлиманиту свойственно небольшое изменение объема только при температуре пор дка 1718°К,powder representing co6ofi A1203-5102. Its melting point is 2089 ° K. Sillimanite is characterized by a small change in volume only at temperatures of about 1718 ° K,

прп низких температурах никаких объемных изменений не наблюдаетс .There is no volumetric change in low temperatures.

Claims (2)

Наибольшую прочность имеют стержни, изготовленные из состава 1, асж 1350-10 н/м. Стержни из составов 2 и 3 с граничными значени ми ингредиентов имеют прочность ниже, чем стержни из состава 1 (со средним значением ингредиентов), примерно в 1,2-1,8 раза , а стержни из состава 6 (прототип) имеют прочность в 2,3-2,4 раза меньше, чем стержни из предлагаемой смеси. Чистота поверхности стержней, полученных из предлагаемого состава, соответствует 6-7 классу ГОСТа 2789-73. Формула изобретени  Смесь дл  изготовлени  литейных водорастворимых стержней, включающа  нитраты кали  и натри  и огнеупорный наполнитель - дистен-силлиманит, отличающа с  тем, что, с целью увеличени  прочности стержней и улучшени  качества поверхности отливок, ингредиенты вз ты при следующем соотношении , вес. %: Нитрат натри 30-38 Нитрат кали 35-45 Огнеупорный наполнитель - дистен-силлиманитОстальное Нсточники информации, прин тые во внимание при экспертизе 1.Совершенствование литейного производства в турбостроении, М., Информт жмаш, 1969, с. 15. Rods made of 1, asg 1350-10 n / m have the greatest strength. The rods from compounds 2 and 3 with the boundary values of the ingredients have a strength lower than the rods from composition 1 (with an average value of ingredients), about 1.2-1.8 times, and the rods from composition 6 (prototype) have a strength of 2 , 3-2.4 times less than the rods of the proposed mixture. The surface finish of the rods, obtained from the proposed composition, corresponds to 6-7 class GOST 2789-73. Claims An inventive mixture for making water-soluble cores, including potassium and sodium nitrates and a refractory filler — kyanene-sillimanite, characterized in that, in order to increase the strength of the cores and improve the quality of the surface of the castings, the ingredients are taken in the following ratio, wt. %: Sodium nitrate 30-38 Potassium nitrate 35-45 Refractory filler - kyanite-sillimanite Other Information sources taken into account during the examination 1.
