Abstract
Изобретение относитс к черной металлургии , в частности, к устройствам пылеподавлени при заливке чугуна в ковш на литейных дворах доменных печей, и может быть использовано в различных отрасл х промышленности при сливе металлических расплавов в емкости. Целью изобретени вл етс повышение эффективности пылеподавлени . При сливе расплава из желоба 9 в ковш 1 через отверсти 5 и 7 коллектора 2 подаетс газ, который воспламен етс . Происходит химическое поглощение кислорода воздуха и экранирование расплава продуктами сгорани . Газ, выход щий из отверстий 5, экранирует периферийную область ковша, а из отверстий 7 - центральную область ковша. 1 ил.The invention relates to ferrous metallurgy, in particular, to dust suppression devices when casting iron into a ladle in casting yards of blast furnaces, and can be used in various industries in the discharge of metal melts in a tank. The aim of the invention is to increase the effectiveness of dust suppression. When the melt is drained from the chute 9, gas is introduced into the ladle 1 through the holes 5 and 7 of the collector 2, which is ignited. Chemical absorption of oxygen in the air and shielding of the melt by the combustion products occurs. The gas coming out of the holes 5 shields the peripheral area of the bucket, and from the holes 7 the central area of the bucket. 1 il.
Description
Изобретение относитс к черной металлургии, в частности к устройствам пылеподавлени при запивке чугуна в ковш на литейных дворах доменных печей, и может быть использовано в различных отрасл х промышленно- сти при сливе металлических расплавов в емкостиоThe invention relates to ferrous metallurgy, in particular, to dust suppression devices when zapivka iron in a ladle in the casting yards of blast furnaces, and can be used in various industries in the discharge of metal melts in the tank
Пель изобретени - повьштение эффективности пылеподавлени .Pel of the invention - increase of dust suppression efficiency.
Па чертеже показана схема устройства дл подавлени пылевыбросов при сливе расплава в ковш,, поперечное сечение.The drawing shows a diagram of a device for suppressing dust emissions when a melt is drained into a ladle, a cross section.
Устройство содержит размещенный над ковшом 1 (например, чугуновозом) газоподвод щий кольцевой коллекторThe device comprises a gas supplying ring collector placed above the bucket 1 (for example, a cast iron carrier).
2, отсто щий от кромки 3 горловины ковша 1 на {рассто ние 1, составл ющем 0,09-0,14 радиуса R горловины ковша.2, which is separated from the edge 3 of the neck of the bucket 1 by {distance 1, 0.09-0.14 radius R of the neck of the bucket.
Ниже горизонтальной оси 4 коллектора 2 вьшолнены два р да отверстий дл выхода газа. Продольные оси одного р да отверсти 5 направлены в сторону стенки 6 ковша 1 и пересе- ; каютс с ней под углом аб в диапазоне от 30° до значени угла, образованного продольными ос ми, пересекающимис с внутренней кромкой 3 ковша 1. Продольные оси отверстий 7 другого р да пересекаютс с вертикальной осью 8 ковша 1 под углом /3 в диапазоне 20-45Below the horizontal axis 4 of the collector 2 are two rows of holes for the gas outlet. The longitudinal axes of one row of holes 5 are directed toward the wall 6 of the bucket 1 and cross-; they are angled with it in the range from 30 ° to the angle formed by the longitudinal axes intersecting the inner edge 3 of the bucket 1. The longitudinal axes of the holes 7 of another row intersect with the vertical axis 8 of the bucket 1 at an angle of / 3 in the range of 20- 45
