The 120-MT problem.
What has to be true — in crane lift, melt capacity and moulding floor — before a single-piece 120-ton pour is even physically possible.
A 120-tonne single-piece pour is not a scaled-up version of a 20-tonne one. It is a different problem, and most of it is decided before any metal is melted.
Three hard constraints
Crane lift. Melt-shop cranes of 80 and 60 MT are the physical precondition — without them the ladles cannot reach the mould in the time the metal allows.
Melt capacity. A 120-tonne casting is a three-ladle pour, sequenced so the last ladle arrives before the first has begun to skin.
Moulding floor. Six thousand square metres of moulding area exist so that a casting of this size can be built, poured and cooled without displacing the rest of the schedule.
Everything after that — heat treatment, stress relief, machining — is a matter of discipline. Getting the metal into the mould is a matter of physics.
