The Segment family of continuous casting machine (CCM) components plays a pivotal role in shaping, guiding, and cooling semi-finished steel products as they solidify and travel through the casting line. Haijie Machinery’s Segment line combines precision-engineered rollers and modular frame structures to ensure consistent strand geometry, superior surface quality, and minimal downtime. Within this category, four specialized segment types—Bender, Straightener, Bow, and Horizontal—address distinct process requirements from initial bending through final straightening.
Product DescriptionThe Bender Segment imparts the initial curved profile to the newly formed steel strand exiting the mold. By applying controlled deflection, it transitions the hot shell from a vertical to a gently arched trajectory, preventing shell cracking and ensuring smooth billet travel.
Key Features
Adjustable Deflection Radius: Motorized screw-nut adjustment allows on‑the‑fly radius changes without manual intervention.
High‑Temperature Rollers: Ceramic-coated rollers withstand temperatures up to 1,500 ℃, minimizing wear and thermal damage.
Integrated Cooling Channels: Uniform water distribution maintains roller integrity and prolongs service life.
Product DescriptionPositioned downstream of the Bow Segment, the Straightener Segment restores the strand to a straight path, correcting any residual curvature. Using multiple roller rows with variable gaps, it achieves precise alignment for downstream processing such as cutting or coiling.
Key Features
Multi‑Zone Roller Banks: Segmented into entry, middle, and exit zones to fine‑tune straightening force.
Dynamic Gap Control: Hydraulic actuators adjust roller spacing in milliseconds to accommodate varying billet sizes (80–160 mm).
Stress‑Relief Design: Minimizes induced tensile stresses, reducing microcracks in the shell.
Product DescriptionThe Bow Segment is an intermediate module that imparts a controlled, convex bend opposite to the Bender Segment, counteracting torsional stresses accumulated during the initial curve. It helps maintain shell integrity by balancing mechanical loads.
Key Features
Opposing Curvature: Precisely engineered geometry to neutralize over‑bending without manual recalibration.
Low‑Friction Bearings: Sealed roller bearings reduce maintenance frequency and prevent ingress of scale.
Modular Frame: Quick‑release clamps enable rapid segment replacement during scheduled shutdowns.
Product DescriptionThe Horizontal Segment provides a stable, level conveyance platform once the strand is fully solidified. It ensures consistent cooling and supports the weight of heavy billets prior to cutting or stacking.
Key Features
High‑Load Capacity: Steel‑fabricated frames rated for loads up to 50 t per segment.
Shock‑Absorbing Mounts: Vibration dampers protect rollers and adjacent equipment from dynamic impacts.
Inline Cooling Sprays: Integrated nozzles deliver uniform quench water to finalize the strand’s metallurgical structure.
Unmatched Reliability: Engineered for 24/7 operation, our segments boast an average service life of over 200,000 hours with minimal unplanned downtime.
Precision Control: Servo‑driven adjustments and real‑time monitoring ensure process repeatability within ±1 mm of strand profile.
Energy Efficiency: Optimized roller bearings and low‑pressure water circuits reduce operational costs by up to 10%.
Modular Scalability: Standardized mounting interfaces allow easy expansion or reconfiguration of casting lines.
Rapid Maintenance: Tool‑free access panels and quick‑disconnect couplings enable segment swaps in under 4 hours.
Billet & Bloom Production: Casting of carbon steel billets (100 × 100 mm to 160 × 160 mm) and ingots.
Alloy & Stainless Steel Lines: Specialized coatings and materials accommodate corrosive or high‑alloy melts.
Automotive-Grade Steel: Precision strand control supports downstream cold rolling for automotive sheet applications.
Long Product Casting: Adapts seamlessly to beam blank and bloom casting operations for structural sections.
What is the standard delivery lead time for a complete segment set?
Typical lead time is 14–18 weeks after order confirmation, depending on segment complexity and customization.
Can Haijie segments be retrofitted to existing CCMs from other OEMs?
Yes. Our modular design and adjustable mounting brackets support integration with most major continuous casting platforms.
How is roller wear monitored and managed?
Optional laser‑based gap sensors and inline temperature probes provide real‑time data; predictive maintenance schedules can be configured via SCADA.
Is on‑site commissioning and operator training provided?
We offer turnkey services, including installation supervision, mechanical and electrical commissioning, plus operator & maintenance training.
