Description
54) ВАННА ДЛЯ НАНЕСЕНИЯ ПОКРЫТИЙ 54) BATHTUB FOR APPLYING COATINGS
1one
Изобретение относитс к металлургии и может быть использовано при изготовлении ванн дл нанесени покрыти из расплавов, например, дл цинковани или алюминировани изделий .The invention relates to metallurgy and can be used in the manufacture of molten baths, for example, for galvanizing or aluminizing products.
Известна ванна дп нанесени покрытий из расплавов, содержаща футерованный изнутри графитом металлический кожух, заполненный расплавом дл алюминировани .1.The famous melt coating dp bath containing graphite-lined metal casing filled with melt for aluminization. 1.
Однако часть графитовой футеровки известной ванны, не соприкасающа с с расплавом, не имеет достаточной стойкости при повышенных температурах и разрушаетс при контакте с кислородом воздуха.However, a portion of the graphite lining of the known bath, which is not in contact with the melt, does not have sufficient resistance at elevated temperatures and collapses upon contact with atmospheric oxygen.
-Целью изобретени вл етс повышение срока службы футеровки.The object of the invention is to increase the life of the lining.
Поставленна цель достигаетс тем, что металлический кожух в верхней части выполнен с .желобом по всему- периметру, заполненным герметизирующим жаростойким составом, а. верхний край ванны по всему периметру заключен в керамический элемент Г-образного поперечного сечени , погруженный одним концом в герметизирующий жаростойкий:состав желоба, а рругим концом - в расплав ванны. ИЗ РАСПЛАВОВThe goal is achieved by the fact that the metal casing in the upper part is made with a groove around the perimeter, filled with a sealing heat-resistant composition, and. The upper edge of the bath around the perimeter is enclosed in a ceramic element of an L-shaped cross section, immersed at one end in a sealing heat-resistant: the composition of the trough, and the other end - in the bath melt. FROM MELTS
Кроме того, герметизируюпщм жаростойким составом может быть свинец, солевой расплав или керамический пос рошок.In addition, the heat-resistant composition can be sealed with lead, molten salt, or ceramic powder.
На чертеже показана схема ванны.The drawing shows a bath diagram.
Ванна содержит металлический кожух 1 с графитовой ИЛИ графитосодержащей Футеровкой 2. В верхней части .« кожух 1 с наружной его стороны по всему периметру выполнен с желобом 3, заполненным герметизируювдам жаростойким составом 4. Верхний край ванны по всему периметру заключен в керамический элемент 5 Г-образного поперечного сечени . Стенка 6 керамического элемента 5 погружена в состав 4, а стенка 7 - в расплав 8.The bath contains a metal casing 1 with graphite OR graphite-containing lining 2. In the upper part. shaped cross section. The wall 6 of the ceramic element 5 is immersed in part 4, and the wall 7 is in the melt 8.
Указанное выполнение и расположение керамического элемента исключает The specified execution and location of the ceramic element excludes
20 контакт футеровки с кислородом воздуха , что исключает ее газовую коррозию и разрушение и продлевает срок службы до года и более.20 contact of the lining with air oxygen, which eliminates its gas corrosion and destruction and extends the service life to a year or more.
