Description
Известны газовые вагранки с холостой огнеупорной колошой, в которых нижн часть шахты заполнена огнеупорной насадкой.Gas cupolas with a single refractory ear are known, in which the lower part of the shaft is filled with a refractory nozzle.
Предлагаемый горн доменной печи выполнен с наполнителем - огнеупорной насадкой. Это исключает контакт жидкого металла с коксом, что может уменьшить содержание углерода и серы в чугуне.The proposed horn of a blast furnace is made with a filler - a refractory nozzle. This eliminates the contact of the liquid metal with coke, which can reduce the carbon and sulfur content in the iron.
На фиг. 1 изображен описываемый горн с насадкой пр моугольной формы; на фиг. 2 - горн с насадкой овальной формы.FIG. 1 shows the described horn with a rectangular nozzle; in fig. 2 - horn with an oval-shaped nozzle.
Материалом насадки может быть углеродистый , графитовый, цирконовый кирпичи. Насадка может быть пр моугольной, овальнойThe material of the nozzle can be carbon, graphite, zircon bricks. Nozzle can be rectangular, oval
или другой формы, обеспечивающей достаточный дренаж горна. Стенки горна с насадкой могут быть вертикальными или коническими с )асширеинем к низу или к верху насадки. Свободный объем насадки составл ет около 2/0 объема горна и не подвергаетс давлению столба шихты. Всплывапие кирпичей насадки предотврашаетс наличием столба шихты.or another form that provides adequate drainage of the forge. The walls of the hearth with the nozzle can be vertical or conical c) with the extension to the bottom or to the top of the nozzle. The free volume of the nozzle is about 2/0 the volume of the hearth and is not subjected to the pressure of the charge column. The pop-up of the nozzle bricks is prevented by the presence of a charge column.
