Continuous Casting Equipment Category Overview
Continuous Casting Equipment (CCE) represents the heart of modern steel and non‐ferrous metal production, transforming molten metal into semi‐finished billets, blooms, slabs, or beam blanks with high precision and efficiency. Haijie Machinery’s CCE portfolio encompasses the full spectrum of casting systems—from tundish and mould assemblies to secondary cooling and cutting units—engineered to deliver uniform internal structure, superior surface quality, and maximum line uptime.
Haijie’s Continuous Casting Equipment integrates key modules that work in concert to convert liquid steel into solidified strands:
Tundish & Flow Control: Multi‐strand tundishes with electromagnetic or slide‐gate nozzles provide independent flow regulation, ensuring equal metal distribution and minimizing nozzle clogging.
Mould Assembly: Copper or Cu–Cr–Zr alloy moulds with precise taper and oscillation systems maintain consistent shell thickness; mould flux feeding and lubrication systems optimize heat transfer and surface finish.
Secondary Cooling Zone: A sequenced roller table with segmented spray headers applies controlled quench water flow, achieving target shell growth rates and metallurgical properties.
Straightening & Cutting: Integrated straightener segments and high‐precision hydraulic or plasma cutters deliver clean, square ends for downstream processing.
Run‐Out Table & Withdrawal: Heavy‐duty rollers and driven pullers extract and carry the strand at speeds up to 6 m/min, seamlessly interfacing with shear, bundling, or rolling lines.
Multi‑Strand Flexibility
Configurations from single‐strand up to six‐strand lines with individual casting widths from 80 mm billets to 1,600 mm slabs.
Advanced Thermal Control
Customized secondary cooling zones with zoned nozzle banks, enabling independent water flow rates (up to 150 L/min per nozzle) for precise shell solidification.
Oscillation & Roll Gap Precision
Servo‑controlled mould oscillation with adjustable stroke (5–12 mm) and frequency (0.5–1.2 Hz), coupled with gap monitoring for consistent strand thickness within ±0.2 mm.
Intelligent Automation
Integrated PLC/SCADA platform with recipe management, real‑time temperature and flow monitoring, and automated defect detection via infrared cameras and eddy‑current sensors.
Rapid Changeover Design
Quick‑release tundish and mould units, plus modular spray headers, permit strand size changes in under 4 hours, minimizing production loss during grade switches.
High Throughput & Yield
Capable of melting rates up to 10,000 t/day on six‐strand slab casters, with scrap rates below 1.2 % thanks to optimized fluid flow and thermal profiles.
Enhanced Product Quality
Tight control over thermal gradients yields fine equiaxed grain structures and surface roughness Ra ≤ 1.6 μm, suitable for high‑strength and critical‐application steels.
Energy Efficiency & Sustainability
Recuperative flow lines recover up to 15 % of heat from off‑gas; low‐pressure cooling circuits cut total water consumption by 20 %.
Modular Scalability
Standardized module interfaces allow incremental expansion—adding strands or upgrading cooling capacity—without major civil works.
Minimal Downtime
Predictive maintenance package uses vibration, temperature, and flow analytics to schedule service interventions, achieving availability > 95 %.
Slab Casting for Plate Mills
Producing slabs (1,100–1,600 mm wide, 150–300 mm thick) for downstream hot‐rolling into heavy plates and structural sections.
Billet & Bloom Casting
Manufacturing smaller sections (80–160 mm square) destined for bar, wire rod, and section rolling mills in automotive and construction sectors.
Beam Blank Casting
Casting wide‐flange and H‑beam blanks (350–600 mm square) for large structural steel applications.
Non‑Ferrous Casting Lines
Adaptable to copper, aluminum, and specialty alloys with tailored flux, mould, and cooling designs.
Flexible Strand Addition
“Plug‑and‑play” ports in tundish platforms accommodate the future commissioning of extra strands.
Alloy & Inclusion Control Modules
On‑line electromagnetic stirring, argon bubble injection, and inclusion flotation sinks improve internal cleanliness.
Advanced Safety Packages
Infrared hot‐spot detectors, redundant brake systems on run‑out tables, and gas‐fired emergency tundish preheater.
Digital Twin & Simulation
Pre‑commissioning flow and thermal modeling via CFD/FEA; virtual commissioning reduces ramp‑up times by 30 %.
What casting speeds can Haijie CCE achieve?
Up to 6 m/min for billets/blooms and 3 m/min for slab strands, depending on section size and alloy grade.
How long does a strand size changeover take?
Standard quick‑release modules allow tundish and mould swap in under 4 hours, with full line re‑balancing in 6–8 hours.
Can the system handle high‑alloy or stainless steel?
Yes. Specialized mould materials, enhanced flux feeders, and cooled launder systems accommodate alloy grades up to 30 Cr or duplex stainless steels.
What water quality is required for secondary cooling?
Deionized or filtered make‑up water with conductivity < 10 μS/cm is recommended to prevent nozzle clogging and scale formation.
Do you provide turnkey installation and commissioning?
Haijie offers full EPC services: foundation works, equipment supply, erection, commissioning (FAT/SAT), and operator training for a true “green‑field” delivery.
