FIELD: devices for highly efficient process of continuous casting of blocks. SUBSTANCE: highly efficient continuous casting of blocks is ensured by making the surface of nozzle outlet according to the law Y=0.5 Xm with m= 2,3,4. In addition, angle β of axis of nozzle outlet relative to the surface of inclined face equals 2-10 deg and angle b of inclination of the axis downward to horizontal equals 5-10 deg. Nozzle outlets are parallel to inclined face at angle g to the surface. To improve mixing of metal inside the nozzle, its bottom part is made spherical with radius R=(1.5-6.0)b with the interval between the inner edges of slot holes in nozzle bottom part c=(1-10)b, where b is width of nozzle outlet. EFFECT: higher efficiency. 3 cl, 5 dwg
