Continuous-casting mold

Abstract

A continuous-casting mold has an inner mold tube having a plurality of side walls formed with coolant passages and a plurality of profiles extending longitudinally on each of the side walls and each formed with a respective plurality of longitudinally spaced undercut grooves. An outer jacket surrounds the mold tube. Respective connectors each have a base generally complementarily fitting in a respective one of the grooves and a tubular and internally threaded body projecting outward from the respective base. Respective screws engage from outside through the jacket into the bodies.

1 . A continuous-casting mold comprising:
 an inner mold tube having a plurality of side walls formed with coolant passages;   a plurality of profiles extending longitudinally on each of the side walls and each formed with a respective plurality of longitudinally spaced undercut grooves;   an outer jacket complementarily surrounding the mold tube;   respective connectors each having a base generally complementarily fitting in a respective one of the grooves and a tubular and internally threaded body projecting outward from the respective base; and   respective screws engaged from outside through the jacket into the bodies.   
     
     
         2 . The continuous-casting mold defined in  claim 1 , wherein each of the grooves extends transversely of the respective longitudinally extending profile and the passages are defined between the profiles. 
     
     
         3 . The continuous-casting mold defined in  claim 1 , wherein the bases and the grooves are of T-section. 
     
     
         4 . The continuous-casting mold defined in  claim 1 , wherein each of the tubular bodies has a frustoconically outwardly tapered outer end. 
     
     
         5 . The continuous-casting mold defined in  claim 1 , wherein the jacket is formed by a respective side plates juxtaposed with the side walls and each formed with an array of holes aligned with the grooves and through which the screws engage and into which the respective cylindrical bodies engage. 
     
     
         6 . The continuous-casting mold defined in  claim 5 , wherein each screw has a head and a shank, each of the holes being formed with an internal restriction on which the head of the respective screw bears. 
     
     
         7 . The continuous-casting mold defined in  claim 6  wherein each of the holes is countersunk outward of the respective restriction, whereby the screw heads are countersunk beneath an outer face of the respective plate.
