Modern Metal Strip Finishing Solutions & Domestic Replacement Equipment from Xiangyang Jiade Machinery

2026-07-11 16:47:03

The global metal processing industry faces consistent production pain points: strip residual stress causing furnace breakage, poor trimming edge quality generating excessive burrs, uneven silicon steel coating leading to degraded magnetic performance, and imported spare parts with long lead times and high costs. As a wholly-owned subsidiary of Chaozhuo Aviation Technology (Stock Code: 688237), Xiangyang Jiade Machinery stands out as a professional full-chain metal strip finishing equipment manufacturer, delivering integrated leveling, shearing, coating, rolling mill spare parts and precision component solutions for carbon steel, stainless steel, aluminum alloy, silicon steel and advanced high-strength steel (AHSS) production lines.

1. Tension Leveling & Scale Breaking Units: Eliminate Strip Defects & Boost Descaling Efficiency

Tension leveling equipment is the core unit to fix edge waves, center buckles, coil set and camber by controlled plastic elongation of metal strips. Xiangyang Jiade develops a complete lineup of Tension Levelers covering multiple process scenarios:

• Steel coil tension Levelers: Two-bend one/two-level, three-bend two-level dry/wet models, processing 0.15–6.0mm carbon steel, stainless steel and titanium strips at a maximum line speed of 750m/min, widely matched to hot galvanizing lines, continuous annealing lines and color coating lines.

• Aluminum coil tension levelers: Customized for 0.2–4.0mm aluminum strips with a maximum width of 2500mm, tailored for aluminum cold rolling and Recoil lines.

• Scale breakers (descaling tension levelers): Two-bend one-level and three-bend one-level swing/vertical cassette designs for pickling lines, mechanically cracking iron oxide scales to improve pickling efficiency by over 35% while correcting strip flatness within 20–50I units.

• multi-roll tension levelers (23-roll series): Designed for ultra-thin hard-state stainless steel, titanium and copper strips (0.02–0.8mm). Adjustable lower roll crown eliminates local plate defects to achieve finished flatness of 3–5I units, ideal for precision electronic metal strip production.

• Multi-roll Straighteners: 5/7/9/11/13/17/19/23 roller Straighteners for aluminum, AHSS and general steel sheets, with customizable roll configurations for customer-specific flatness tolerance demands.

All Jiade tension leveler Roll cassettes absorb core technologies from Siemens-VAI, Danieli, SMS and Mitsubishi Hitachi, realizing full domestic replacement of imported roll box spare parts with high rigidity and waterproof sealing design to extend bearing service life.

2. Shearing System: High-Speed, Burr-Free Side Trimming & Dynamic Cut-to-Length Solutions

Unqualified trimming edges, frequent blade changes and line downtime severely restrict cold rolling line output. Jiade’s complete shearing product portfolio resolves these bottlenecks:

Turret-Type Side Trimmer & Scrap Handling System

Split into driven/pull-through single/double turret designs, the turret double-head side trimmer supports online rapid head switching within 5 minutes without full-line shutdown, drastically lifting production efficiency. Core precision indicators include:

• Blade end face runout ≤0.003mm, radial runout 0.01–0.015mm

• Trimming width accuracy ±0.2mm, cutting thickness range 0.15–6mm

• Max running speed up to 700m/min, compatible with silicon steel, coated steel and stainless steel strips

Supporting auxiliary equipment includes single/mobile/turret double scrap choppers, scrap coil rewinders and scrap conveyors, forming an integrated trimming & scrap recovery unit for high-speed pickling, galvanizing and silicon steel lines.

Drum Flying Shear (Cut-to-Length Equipment)

Applied to cold mill exit dynamic coil separation, this flying shear handles 0.3–4.0mm strips with maximum tensile strength up to 1180MPa. Controlled blade clearance adjustment ensures parallelism of upper/lower blades ≤±0.03mm, used for strip splitting, waste cutting and sampling on continuous cold rolling lines.

3. Surface Coating Machines for Galvanized & Silicon Steel Lines

Uniform functional coating is critical to anti-corrosion performance of galvanized steel and low core loss of silicon electrical steel. Jiade’s two core coating models cover mainstream post-treatment lines:

1. Galvanized line roller coater: Applies passivation and fingerprint-resistant liquid on single/double sides of galvanized strips (0.2–4.0mm thickness, line speed ≤280m/min), forming a protective film to enhance corrosion resistance and extend product service life.

2. silicon steel coating machine: Specialized for CA continuous annealing coating lines, DCL decarburization annealing lines and FCL hot leveling coating lines, processing 0.15–0.65mm silicon steel strips with consistent insulating coating thickness to stabilize magnetic permeability and reduce eddy current loss of finished silicon steel sheets.

4. Rolling Mill Spare Parts & Precision Custom Components

Beyond complete production lines, Jiade supplies full-series supporting parts for multi-high rolling mills and finishing units, realizing one-stop spare part procurement:

Rolling Mill Auxiliary Equipment

18-roll mill side roller assemblies, 20-roll mill main shaft saddles and oil removal devices. The oil removal unit eliminates residual rolling oil and emulsion on strip surfaces to avoid surface streaks and annealing defects in downstream processes.

Precision Custom Spare Parts

1. Non-standard bearings: Fracturing pump cylindrical roller bearings (NU/NUP/NJ types) replacing imported models for petroleum fracturing units; back-up rolls (24.5–260mm diameter) and rotary joints for tension levelers and scale breakers, designed for high-speed, heavy-load and waterproof working conditions.

2. Couplings: Ball cage constant velocity universal couplings (working angle 0°–75°, torque range 380–1,000,000 N·m) and drum spline couplings for low-speed high-torque narrow-space transmission scenarios.

3. Roller parts: Work Rolls (Φ9–Φ630mm, length ≤4000mm) and intermediate rolls for leveling machines, with small-diameter roll designs to avoid strip surface indentation and deliver ultra-precise flatness correction.

4. Roll cassettes: Dedicated roll boxes for tension levelers, scale breakers, multi-roll tension levelers and multi-roll straighteners, integrated with crown adjustment mechanisms for high-precision strip finishing.
