Steel plate Preservation line: shot blasting & Painting line

    The surface treatment system for industrial preservation lines integrates automated shot blasting, painting lines, spray booths, and in-line drying ovens to treat steel sheets, profiles, structures, and strips. Engineered for high productivity, it utilizes continuous horizontal roller conveyors to streamline material handling, reducing downtime and boosting cost-effective industrial solutions.

    Key Features of the Preservation Line
Central to the system is the roller conveyor shot blasting machine, enhanced with a sweeping system and high-pressure fan blowing system to eliminate residual blast media from surfaces. A pre-heater ensures optimal preparation of damp or cold steel parts before entering the high-performance shot turbines, which efficiently clean, descale, and texture surfaces. Post-blasting, components advance through an automated paint system for uniform dual-sided coating, improving corrosion resistance.

    Efficient Process Workflow
After coating, parts transition to heating chambers for rapid curing, followed by a gas removal system to ensure safety and finish quality. This industrial-grade preservation line prioritizes material handling efficiency, reducing manual intervention while delivering consistent, durable results for steel fabrication and metalworking industries. Ideal for high-volume production, it combines precision, speed, and eco-friendly surface treatment technology.

  • The Automatic PLC control system optimizes labor cost savings while ensuring perfect finishing consistency in surface cleaning quality.
  • Its continuous feed capability efficiently processes beams, plates, and profiles, supported by robust wheel turbines crafted from high-chrome wearing-resistant material with multi-grade projectile capacity.

FAQs

What is "steel-plate preservation line"?

A steel plate preservation line is an integrated system for cleaning, descaling, coating, and drying metal components like sheets, profiles, and structures. It uses automated processes (e.g., shot blasting, pre-heating, painting, drying ovens etc.,) to enhance corrosion resistance and durability.

Maintenance for "Plate shot blasting machine"?

Regular check for the shot abrasive using condition, wearing parts for the shot turbines (the inside protective liners), the lubrication condition for motors/reducers and dust collector filters (bags or cartridges).

What is the purpose of the pre-heater in the preservation line?

The pre-heater removes moisture and pre-warms cold or damp steel parts to optimize adhesion during shot blasting and coating, improving process reliability.

What are applications of steel sheet shot blasting machine?

1. Surface Preparation for Welding: Achieve contaminant-free, weld-ready surfaces via abrasive blasting to ensure strong, durable welds and prevent porosity/defects.
2. Pre-Painting/Coating Prep: Create uniform SA 2.5-3 surface profiles through shot blasting for superior paint adhesion and long-lasting corrosion-resistant coatings.
3. Rust & Scale Removal: Eliminate corrosion, mill scale, and oxidation via industrial metal cleaning, restoring plates to rust-free condition for reuse or CNC machining.
4. Deburring & Surface Finishing: Automate edge radiusing, micro-finishing, and custom Ra surface treatments for machined components using precision abrasive processes.
