Description
Предметом изобретени в.шетс состав сол ной ванны, примен емый 3 качестве теплоносител и обеспечивающий рабочую температуру в интервале 400-600.The subject matter of the invention is a salt bath composition, used as heat carrier 3 and providing an operating temperature in the range of 400-600.
Обычно в качестве теплоносителей в термическом производстве примен ютс смеси азотнокислых или хлористых .солей. Недостатком этих смесей вл етс их нестабильность (разложение при температуре выше 500°) и взрывоопасность (в случае применеш ванн с азотнокислыми сол ми), а также сравнительно высока температура плавлени хлористых солей и известна агрессивность расплава их дл оборудовани .Usually mixtures of nitric acid or chloride salts are used as heat carriers in thermal production. The disadvantage of these mixtures is their instability (decomposition at temperatures above 500 °) and explosiveness (in the case of baths with nitric acid salts), as well as the relatively high melting point of chloride salts and their aggressiveness to melt their equipment.
Насто щим изобретением предлагаетс в качестве теплоносител примен ть расплавленные смеси сульфатов натри , цинка и кали , обладающие высокой термической стойкостью, низкой .тетучестью п сравнительно невысокой коррозийной активностью по отношению к металлу оборудовани .The present invention proposes to use molten mixtures of sodium, zinc and potassium sulfates as a heat carrier, which have high thermal stability, low volatility and relatively low corrosive activity with respect to the metal of the equipment.
(ДЮЙ TaKiix смесей вл етс . например, эвтектическа , содержаща сернокислый цинк - 41.2%. сернокислый натрий-25.) ii сор;:Слис.-1ыи - 33% ) имеlonuiH тсмпер; туру плавлени 384°.(DUK TaKiix mixtures are. For example, eutectic, containing zinc sulphate - 41.2%. Sodium sulphate-25.) Ii sor; melting point 384 °.
Возможно испо.тьзование не только смесей чистых сульфатов мета .п.чов, по и с небольшими добавками других солей.It is possible to use not only mixtures of pure sulphates of meta-grade, but also with small additions of other salts.
Предмет изобретени Subject invention
.1. Состав сол ной ванны, примен емый в качестве теплоносител и обеспечивающий рабочую температуру в интервале 400-600°, отличающийс тем, что, с целью обеспечени высокой термической стойкости при низкой коррозионной активности, он состоит из смеси, основными колшоиентами которой вл ютс сульфаты натри , цинка и кали ..one. The composition of the salt bath, used as a heat carrier and providing a working temperature in the range of 400-600 °, is characterized in that, in order to ensure high thermal stability at low corrosivity, it consists of a mixture, the main components of which are sodium sulfates, zinc and potassium.
2. Состав по п. 2, отличающийс тем, что он содержит сернокислого цинка 41,2%, сернокислого натри 25,8% и сернокислого кали 33%.2. The composition according to claim 2, characterized in that it contains zinc sulfate 41.2%, sodium sulfate 25.8% and potassium sulfate 33%.
