Description
Существующие экранированные сопла на доменных печах требуют дл изготовлени внутренней оболочки дефицитной жаронрочной стали, котора сравнительно быстро выходит из стро .Existing screened nozzles on blast furnaces require the manufacture of an inner shell of deficient hot-melt steel, which is relatively quickly out of order.
С целью повышени срока службы металлического сопла предлагаетс изолировать его от действи гор чего воздуха посредством огнеупорной обмазки толщиной Ю-20 мм. Обмазка составл етс из 90Vo пеношамота фракции I-2 мм и 10% периклазощнинСоТитового норошка фракции от О до 1,5 мм. Смесь этих порошков смачиваетс жидким стеклом до такого состо ни , при котором она приобретает пластичность, наноситс на поверхность и затем обжигаетс в печи до 1000.In order to increase the service life of the metal nozzle, it is proposed to isolate it from the action of hot air by means of a refractory coating with a thickness of 10-20 mm. The coating is comprised of a 90Vo penosamoth fraction of I-2 mm and 10% periclazoscinSo-titanium grain of the fraction from 0 to 1.5 mm. The mixture of these powders is wetted with liquid glass to the point where it becomes plastic, is applied to the surface and then burned in a kiln up to 1000.
Такой состав обмазки позвол ет повысить жаростойкость сопла п предохран ет его металл от перегрева.Such a composition of the coating makes it possible to increase the heat resistance of the nozzle and prevents its metal from overheating.
Таким же способодг можно предохран ть от действи гор чего воздуха и другие дета,ти металлургического оборудовани : шиберы, кольца шиберов и т. п.The same method can be protected from the action of hot air and other parts of metallurgical equipment: gate valves, gate rings, etc.
