Estimating the term…
The invention relates to the iron and steel industry, more specifically, to continuous slab casting using a submerged nozzle. The inventive submerged nozzle comprises a bottom, lateral channels and a skirt which is secured to the lower part of the nozzle above the output lateral channels and is formed by two parallel flat surfaces which are gradually conjugated on the ends thereof by means of cylindrical surfaces. The nozzle is arranged in the center of the skirt and has two similar oppositely positioned lateral channels having a common longitudinal axis which forms together with the parallel flat surfaces of the skirt an acute angle ranging from 20 to 45°.
A submerged nozzle comprising a bottom, side channels and a skirt fixed to the lower part of the nozzle above the outlet side channels, in the lower part characterized in that the skirt is formed by two parallel flat surfaces which are smoothly mated with the edges by means of cylindrical surfaces, besides the nozzle is located in the center of the skirt and has two opposite identical side channels with a common longitudinal axis making a sharp angle with the parallel flat surfaces of the skirt.
