Product Description
Manufactured within our specialized heavy equipment facility in Jingjiang, our Steel Billet Turntable is a heavy-duty material-handling unit engineered to rotate hot steel billets, blooms, and ingots 90 or 180 degrees between rolling passes in hot breakdown and roughing mills. Drawing upon 26 years of heavy fabrication experience and serving premier steel groups such as Baowu, Nangang, and POSCO, we construct each Steel Billet Turntable with heavy-duty slewing bearings, reinforced welded structural carousels, and motorized or hydraulic indexing drives engineered to endure severe mechanical shock and thermal radiation. By automating ingot orientation before the piece enters primary blooming mills or breakdown roll passes, this reliable Steel Billet Turntable eliminates manual handling delays and prevents mill misalignments, providing continuous hot-rolling operations with a durable, shock-resistant material positioning asset.
Applications
Billet & Bloom Breakdown Mills: Rotating cast ingots and square billets 90° or 180° for multi-pass breakdown rolling.
Reheating Furnace Feed & Exit Lines: Turning hot billets discharged from furnaces to align with mill approach roller tables.
Continuous Casting Run-Out Sections: Indexing cut blooms and billets between cooling beds, storage yards, and direct-charging routes.
Heavy Forging Manipulator Lines: Orienting large hot ingots prior to open-die forging and cogging operations.

Customization Capabilities
Drive Mechanism Tailoring: Electric slewing ring drive or hydraulic cylinder linkage configurations sized to match your mill layout and cycle times.
Integrated Roller Conveyor Bed: The turntable surface can incorporate motor-driven rollers to receive, turn, and discharge billets on a single footprint.
Thermal Heat Shielding: Under-table water-cooled heat shields and ceramic thermal barriers to protect slewing rings and drive motors from direct ingot radiation.
Precise Hydraulic Centering: Automatic hydraulic clamps and optical sensors to center billets before rotation, preventing off-center rotation loads.
Zero MOQ Restriction: Custom-designed for single blooming mill modernizations or supplied as part of multi-stand greenfield mill lines.
Quality Control
Manufacturing Accreditations: ISO 9001:2015, ISO 14001:2015, and ISO 3834-2 welding quality management.
Full Process QR Code Traceability: Slewing rings, drive shafts, structural frames, and hydraulic cylinders carry individual QR codes linked to mill test reports and inspection logs.
Non-Destructive Testing: 100% Ultrasonic Testing (UT) on heavy turntable structural weldments; Magnetic Particle Testing (MT) on drive pinions and splines.
Shop Load & Rotation Testing: Full factory dry-cycling and indexing accuracy checks under simulated unbalanced loads to verify torque and limit-switch precision.
Heavy Ocean Packaging: Sturdy steel shipping bases, greased gear teeth, vapor-phase corrosion inhibitors, and heavy weatherproof packaging.
FAQ
Q: How does the turntable protect its slewing bearing from the heat of 1,000°C steel ingots?
A: We incorporate heavy heat-deflector aprons, high-temperature thermal insulation tiles beneath the roller deck, and optional water-cooling jackets around the slewing ring housing, combined with high-temperature synthetic grease.
Q: What is the typical fabrication lead time for a billet turntable?
A: Production typically requires 3 to 4 months from technical drawing approval to final factory testing.
Q: What warranty coverage do you provide?
A: We provide an 18-month warranty from site arrival or 12 months from commercial operation (whichever occurs first).
Q: What payment terms are accepted?
A: Standard commercial terms are 30% advance deposit, 40% manufacturing milestone payment, and 30% balance prior to export shipment, payable in USD, EUR, or RMB.
