Connection geometry
The chain-to-dummy-head interface must close securely, carry load correctly, and release as intended during the start sequence.
Continuous casting
The first controlled link in the casting sequence
A starter bar chain has to guide the dummy head into position, withstand the first strand pull, and release into the casting route without damaging the caster or interrupting the start. The useful question is not only whether the chain is strong, but whether every connection, pin, pocket, and machined face matches the actual line.
- Designed around the caster layout, starter bar length, bend radius, and dummy head connection
- Machined interfaces for repeatable fit between chain elements, pins, locking points, and the dummy head
- Wear-zone planning for surfaces exposed to sliding contact, impact, heat, and repeated start cycles
- Inspection and documentation support for plants that need traceable replacement components
System fit
What must be right before the first heat
Articulation
Link movement, pin condition, clearances, and bend behaviour matter where the starter bar travels through guides and curved sections.
Contact surfaces
Sliding and impact areas can be machined, protected, or reconditioned according to the line's wear pattern.
Replacement certainty
When drawings are incomplete, worn parts, photos, and measurements can help rebuild the geometry for a controlled replacement.
Production route
From existing chain to replacement set
Identify line data
Confirm caster type, starter bar path, connection style, chain length, working environment, and known failure history.
Measure interfaces
Check critical dimensions at pins, pockets, faces, holes, dummy head connection points, and worn contact zones.
Manufacture or repair
Machine replacement elements, restore worn areas, apply surface protection where useful, and control fit across the assembly.
Release with records
Verify dimensions, material route, hardness or surface requirements, and final assembly details before shipment.
Inquiry data
What helps BRUVAL evaluate starter bar chains
- Photos of the full starter bar chain, dummy head connection, pins, locking areas, and worn zones
- Overall chain length, link quantity, key dimensions, approximate weight, and available drawings
- Caster type, strand format, bend radius or route information, and start-up sequence constraints
- Known material, hardness, coatings, or surface protection requirements
- Current problem: excessive wear, cracked links, pin damage, fit loss, difficult release, or repeated start-up failure
- Required quantity, shutdown window, inspection requirements, and whether BRUVAL should reproduce or improve the existing design
