Job Description

1. Job Purpose

To oversee and control all chemical processes in the Hot-Dip Galvanizing plant, ensuring the correct preparation of steel surfaces, maintaining bath chemistry, ensuring high-quality zinc coating in accordance with international standards (ASTM A123 / BS EN ISO 1461), and supporting continuous improvement in production efficiency and product quality.

2. Key ResponsibilitiesA. Chemical Process Control

Monitor, test, and adjust chemical concentrations in all pre-treatment baths (degreasing, pickling, rinsing, fluxing). Prepare and replenish chemical solutions as per required concentration levels. Maintain zinc bath parameters such as: Zinc purity Bath temperature Dross levels Aluminium and iron content

B. Quality Control & Inspection

Inspect steel surfaces before immersion to ensure proper cleaning and preparation. Inspect galvanized products after zinc coating for: Coating thickness Surface finish Adherence Absence of defects (runs, bare spots, ash inclusions). Conduct daily coating thickness tests using magnetic gauges. Ensure production complies with

ISO 1461 / ASTM A123

requirements.

C. Safety & Environmental Compliance

Ensure all chemical handling practices meet HSE requirements. Maintain proper storage and disposal of hazardous materials. Ensure ventilation, PPE usage, bund walls, and emergency procedures are followed. Conduct regular safety audits of chemical areas.

D. Documentation & Reporting

Maintain daily chemical log sheets for: Pickling bath concentration Flux density (Baume) Acid/alkali consumption Zinc bath chemical analysis Prepare weekly and monthly reports for management. Update SDS (Safety Data Sheets) and chemical risk assessments.

E. Plant & Process Optimization

Suggest and implement improvements to reduce chemical consumption and improve product quality. Troubleshoot galvanizing defects (e.g., black spots, bare patches, excessive dross). Coordinate with maintenance team to ensure tank heaters, burners, pumps, and agitators function properly.

F. Training & Support

Train operators on chemical handling, titration, and pre-treatment procedures. Guide production staff in identifying surface defects and quality issues before galvanizing.
