A Continuous Casting Segment Frame is the primary structural element that defines roller position and preserves the geometric reference of the casting line. Installed between mold exit and straightening sections, segment frames maintain strand path stability and provide the datum structure for roller alignment throughout the caster.

From a system perspective, the segment frame is a datum-controlled structure, not only a welded fabrication. Engineers focus on flatness and parallelism of mounting faces, positional accuracy of roller mounting holes, and long-term deformation under thermal and mechanical load. Any drift in these references leads to cumulative misalignment, uneven roller wear, and repeated on-line adjustment.

For acceptance, attention is typically placed on datum definition, mounting face flatness, hole pattern position tolerance, and documented dimensional reports tied to the drawing revision. At RFQ stage, providing segment location, interface drawings, datum scheme, and maintenance method allows machining and inspection plans to be defined to support interchangeability and predictable installation.
