Смеси готов т следующим образом.Mixtures are prepared as follows.
Исходные компоненты загружают.в смеситель и перемешивают в течение 3 мин, затем добавл ют воду до получени тестообразной смеси, которую перемешивают 15 мин.The initial components are loaded into the mixer and stirred for 3 minutes, then water is added until the dough mixture is obtained, which is stirred for 15 minutes.
По мере подсыхани смеси добавл ют воду дл поддержани тестообраэ-, ного состо ни при перемешивании в течение 30 мин с начала загрузки. Полученную тестообразную смесьAs the mixture dries, water is added to maintain the dough-like state with stirring for 30 minutes from the start of loading. The resulting pasty mixture
нанос т на корпус термопары слоем 15-25 мм и высушивают при температуре 280с в течение 4 ч.put on the thermocouple case with a layer of 15-25 mm and dried at a temperature of 280 s for 4 hours.
Термопары с нанесенным защитным покрытием с трем вышеуказанными составами использовались дл замера температуры жидкой.стали в электродуговой печи и в разливочном ковше в течение 12 рабочих смен. При этом защитное покрытие термопар выдержал каждое соответственно 30, 22 и 18 погружений.Thermocouples with a protective coating with the above three compositions were used to measure the temperature of the liquid steel in an electric arc furnace and in a pouring ladle for 12 work shifts. In this case, the protective coating of the thermocouple held 30, 22 and 18 dives, respectively.
Результаты испытаний сведены . В таблицу. :.The test results are summarized. In the table. :.
Предлагаемый состав позвол ет повысить стойкость з.ащитного покрыти в 2,5 раза по сравнению с известным.The proposed composition makes it possible to increase the resistance of the protective coating by a factor of 2.5 compared with the known one.
