Description
Изобретение относитс к стеклу дл безокислительного нагрева в нем заготовок из сталей и сплавов, подлежащих последующей обработке давлением - прессованию, штамповке .The invention relates to glass for non-oxidizing heating in it blanks from steels and alloys to be further processed by pressure - pressing, stamping.
Применение дл этих целей известных стекол , содержащих SiOs, Na20, CaO, АЬОз, MgO, ограничено вследствие того, что покрытие из стекла не выдерживает длительного нагрева за счет большого содержани щелочных окислов.The use of known glasses containing SiOs, Na20, CaO, AlO3, MgO for these purposes is limited due to the fact that the glass coating does not withstand prolonged heating due to the high content of alkali oxides.
Предлагаемое стекло лишено этих недостатков .The proposed glass is devoid of these shortcomings.
Это достигаетс тем, что указанные компоненты вз ты в следующих количествах (в вес. %):This is achieved by the fact that these components are taken in the following amounts (in wt.%):
SiO255-56SiO255-56
АЬОз20-21ABOZ20-21
СаО4-5CaO4-5
MgO4-5 и, кроме того,MgO4-5 and, in addition,
ВгОз14-15VgOz14-15
Температура варки стекла 1500°С, в зкость расплава стекла при 1250°С 10 пз. Выработку сваренного стекла производ т на воду . Полученные гранулы стекла высушивают и измельчают до 20-70 мк. Смесь дл защитного пОкрЫтИ готов т следующего составй (в вес. ч.):The glass melting temperature is 1500 ° С, the melt viscosity of glass at 1250 ° С is 10 pz. The production of welded glass is produced on water. The obtained glass granules are dried and crushed to 20-70 microns. A mixture for protective coating is prepared with the following composition (in weight parts):
Измельченное стекло100Ground Glass100
Бентонит6Bentonite6

Вода40Water40
Полученный шликер нанос т на холодную обезжиренную заготовку кистью или пульверизацией . В процессе нагрева стекло на заготовке оплавл етс и образует сплошной газонепроницаемый слой, который защищает металл от окислени . При остывании стекло легко удал етс с поверхности металла.The resulting slurry is applied to the cold, defatted billet by brush or by spraying. In the process of heating, the glass on the workpiece melts and forms a continuous gas-tight layer that protects the metal from oxidation. When cooled, glass is easily removed from the surface of the metal.
