Description
Изобретение относитс к области металлургии , в частности к процессу непрерывной разливки металлов.The invention relates to the field of metallurgy, in particular to the process of continuous casting of metals.
Известны патрубки, нижний конец которых погружен в металл, выполненные из корунда.Known nozzles, the lower end of which is immersed in metal, made of corundum.
Дл повышени стойкости предлагаетс патрубки выполн ть из фритированного аморфного стекловидного кремнезема.In order to increase the durability, it is proposed that the nozzles be made of fritted amorphous vitreous silica.
Патрубки из фритированного аморфного стекловидного кремнеза получают из порошка стекловидного кремнезема. Сначала получают шликер или тестообразную эмульсию порошка в воде. Эту пасту выливают в гипсовые формы, где отстаиваетс твердый порошок , а вода проходит через поры гипса. Затем патрубок извлекают из формы, просушивают и окончательно обжигают при температуре , достаточной дл спекани , но недостаточной дл преобразовани кремни , который сохран ет стекловидное состо ние.The nozzles of fritted amorphous vitreous silica are obtained from vitreous silica powder. First, a slip or a pasty emulsion of the powder in water is obtained. This paste is poured into plaster molds, where solid powder is settled, and water passes through the pores of the gypsum. The tube is then removed from the mold, dried and finally calcined at a temperature sufficient to sinter, but not sufficient to convert silicon, which retains its vitreous state.
Эти патрубки из фритированного аморфного стекловидного кремнезема обеспечивают полную разливку, котора , например, дл разливочного ковша 40 г и четырехструйной разливки длитс около 40 мин,These nozzles of fritted amorphous vitreous silica provide complete casting, which, for example, for casting bucket 40 g and four-jet casting lasts about 40 minutes,
Предмет изобретени Subject invention
Огнеупорные патрубки дл установки непрерывной разливки, нижний конец которых погружен в ванну жидкого металла, отличающиес тем, что, с целью повышени стойкости , они выполнены из фритированного аморфного стекловидного кремнезема.Refractory pipes for the installation of continuous casting, the lower end of which is immersed in a bath of liquid metal, characterized in that, in order to increase durability, they are made of fritted amorphous vitreous silica.
