Device to discharge liquid steel from a container to a crystallizer with rollers

摘要

Device (10) to discharge liquid steel from a container (12) to a crystallizer (11) with rollers (31, 32), formed by a discharge element (13) arranged between the container (12) and the rollers (31, 32), wherein the discharge element (13) is shaped so as to define a main tank (15) provided with vertical intermediate walls (16, 18) which define a central compartment (19) into which the liquid steel is able to be cast from the container (12). Lateral walls (20, 21) define two lateral compartments (22, 23) communicating with the central compartment (19) by means of apertures (25) made in the lower part of the vertical intermediate walls (16, 18). On the bottom wall (27) of the discharge element (13), between the intermediate walls (16, 18) and the lateral walls (20, 21), discharge apertures (29) are provided through which the cast steel is able to flow downwards. Moreover guide elements (30) are provided at the sides of the discharge apertures (29).
