Famous Hrc Slitting Line Supplier & Factory

Q: What coil processing equipment does Wuxi Jianfa manufacture?

We manufacture complete coil processing lines: slitting lines (rotary shear lines), cut to length lines, flying shear production lines, leveling machines, straightening machines and galvanizing production lines. Equipment can be supplied as a complete line or as individual machines to upgrade an existing line.

Q: Which materials can your slitting and cut to length lines process?

Our lines process hot-rolled, cold-rolled, galvanized, stainless steel and aluminum coils, including high-strength grades. Each line is configured around your thickness range, coil width, yield strength and surface-quality requirements.

Q: How do I choose between a slitting line, a cut to length line and a flying shear line?

Choose a slitting line when you need narrow strips recoiled for tube mills, roll forming or stamping. Choose a cut to length line when you need flat, stacked sheets or plates. Choose a flying shear line when you need high-volume sheet output, because the shear cuts while the strip keeps moving. Combined slitting and cut to length lines are also available.

Q: What information should I send to receive an accurate technical proposal?

Please share the material grade and yield strength, coil thickness and width range, maximum coil weight and inner/outer diameter, required output (strip widths and count, or sheet length range), tolerance and flatness requirements, target line speed and the power supply at your plant.

Q: Do you support installation, commissioning and operator training overseas?

Yes. Our after-sales team supports installation, commissioning and operator training, and continues with remote technical support and spare parts supply after start-up.

Q: Can I visit the factory and inspect my equipment before delivery?

Yes. Buyers are welcome to visit our 40,000 m² facility in Wuxi, Jiangsu, within easy reach of Shanghai by high-speed rail, to review production and inspect their equipment before delivery.

Industrial White Paper & Mechanical Rigor

Engineering Anatomy of Advanced HRC Slitting Systems

Processing Hot Rolled Coils (HRC) up to 25mm thickness demands superior structural rigidity, high-yield torque absorption, and thermal-stress resilience far exceeding light-gauge lines.

Arbor Rigidity & Double-Eccentric Clearance

HRC slitting subjects cutter arbors to massive radial loads. Wuxi Jianfa lines integrate 42CrMo forged arbors, hardened and tempered to HRC 55-58, paired with double-eccentric worm gear adjustment. This eliminates arbor deflection down to ≤0.005mm, preventing edge tearing, burr escalation, and premature tool chipping even on 800 MPa yield materials.

Closed-Loop Constant Tension Recoiling

Variable strip thickness across the hot-rolled master coil creates uneven winding tightness. Our multi-stage tension stands incorporate pneumatically controlled felt-pad friction plates, hydraulic belt-bridles, and digital load cells to deliver precise, localized back-tension. The result is uniformly packed slit coils free of telescoping or center sag.

Dynamic Scrap Balling vs. Rotary Choppers

Side edge trimming on thick HRC creates dangerous, stiff salvage bands. We supply dual oscillating helical scrap cutters with carbide inserts or heavy-duty horizontal scrap winders with hydraulic push-off plates. This guarantees zero scrap jam-ups at processing velocities up to 120 m/min.

Strategic Procurement Q&A

Frequently Asked Questions on HRC Slitting Systems

Essential guidance covering technical requirements, machine sizing, tooling lifecycles, and factory visit inspections.

What coil processing equipment does Wuxi Jianfa manufacture?

We engineer and build complete coil processing systems: heavy and medium gauge Hot Rolled Coil (HRC) slitting lines (rotary shear lines), precision cut-to-length (CTL) lines, flying shear high-speed production lines, 4-Hi and 6-Hi leveling machines, plate straightening units, and continuous galvanizing lines. Lines can be delivered turnkey or as modular drop-in retrofit units.

Which materials can your slitting and cut to length lines process?

Our lines are engineered for hot-rolled carbon steel, cold-rolled steel, galvanized coils, silicon steel, stainless steel (200, 300, 400 series), titanium alloys, and aluminum. Each configuration is tailored around specific client yield strengths (ranging from 235 N/mm² up to 1200 N/mm² AHSS grades), surface sensitivity requirements, and coil dimensions.

How do I choose between a slitting line, a cut to length line and a flying shear line?

Choose a Slitting Line when wide master coils must be converted into multiple tightly wound narrow strips to feed tube welding mills, stamping presses, or cold roll formers. Choose a Cut to Length Line when flat, stacked rectangular sheets or plates are required. Opt for a Flying Shear Line when ultra-high sheet production throughput is mandatory, as the cutting blade tracks the strip continuously without start-stop cycle delays.

What information should I send to receive an accurate technical proposal?

Please provide: (1) Material grade & yield strength (N/mm² or MPa); (2) Coil thickness range (min–max mm); (3) Coil width range (min–max mm); (4) Maximum coil weight (Tons) and inner/outer diameter (ID/OD); (5) Slit output targets (number of cuts, min strip width) or sheet lengths; (6) Flatness & edge burr tolerance thresholds; and (7) Local factory electrical supply specs.

Do you support installation, commissioning and operator training overseas?

Yes. Our dedicated field service team supervises foundation bolt layout, oversees mechanical alignment, integrates electrical power wiring, conducts cold and hot test cutting, and trains your local operators in knife setup, HMI parameters, and routine preventive maintenance.

Can I visit the factory and inspect my equipment before delivery?

Absolutely. We welcome factory visits to our 40,000 m² base in Wuxi, Jiangsu province (35 minutes from Shanghai via high-speed rail). Buyers or designated third-party inspection firms (SGS, TÜV, Bureau Veritas) can witness dry cycling, precision tolerance verification, and load trials prior to sea-freight release.
