Casting ladle gate valves of the type which are designed to be installed and removed from the ladle as a unit, are rebuilt in a work area which includes a disassembly station, a first assembly line including a revolving table for renewing the movable slide parts and a second assembly line including a revolving table for renewing the slide housings, and reassembling the slide parts, slide housings and clamping lids into renewed gate valve units. By preference, the disassembly station, both revolving tables and a conveyor for carrying the units to the work area from the foundry or steel work, and back are served by a slewing crane.

Process and apparatus for renewing sliding gate valve units for casting

A gate-type sliding valve for the outlet of a casting ladle is provided with support arms on which can be pivotably mounted operating means in the form of a hydraulically actuated piston and cylinder and maintained in their operating position by a torque force created by an unbalanced disposition of the weight of the cylinder and piston relative to their pivot mount.

Valve operating means for a molten metal container

A protective nozzle for the outlet passage of a casting ladle includes a body having a conical shape and a through bore with the exterior side surfaces of the body having projections or ridges which aid in the retention and establishing of a mortar joint between the wall of the outlet of the casting ladle and the exterior surface of the nozzle so as to prevent the possibility of the mortar material being washed out of the joint between the nozzle and the walls of the outlet passage of the casting ladle during a casting operation.
