Cooling jacket for an ingot mold for the continuous casting of metal and

Abstract

A cooling jacket for an ingot mold for the continuous casting of metal comprises a tubular element and a grid of stiffening ribs projecting from the outer surface of the tubular element, in which the grid is provided at the intersection of the stiffening ribs with openings or bores which pass also through the tubular element for the passage of fastening elements in form of tie rods therethrough by which an inner tube for the passage of the metal to be cast can be fastened to the cooling jacket with radial clearance. The upright ingot mold in which the cooling jacket is used and which is especially employed for the casting of steel, includes, besides the cooling jacket and the inner tube, an outer shell surrounding the cooling jacket with considerable clearance. The outer shell is closed by plates at opposite ends to which opposite ends of the inner tube are respectively fastened and these plates are provided with openings aligned with the opposite open ends of the inner tube. The space between the tubular element of the cooling jacket and the outer shell is divided by a transverse wall in a lower chamber with which the open lower end of the tubular element of the cooling jacket communicates and a longer upper chamber with which the open upper end of the tubular element communicates. A cooling water inlet communicates with the lower chamber adjacent the separating wall and a cooling water outlet communicates with the upper compartment at the other side and adjacent to the separating wall. A polyphase magnetic inductor is located in the upper compartment around the cooling jacket.
