Ductile Iron Rainwater Manhole Cover B125 A15 Drainage Manhole Cover

Ductile Iron Rainwater Drainage Manhole Cover For Municipal Use

Production Process Overview

Raw Material Preparation

Main material: Pig iron, scrap steel, and recycled materials (unqualified products recovered in production)
Auxiliary materials: Alloy elements (silicon, manganese, copper), spheroidizing agents (magnesium, rare earth), and inoculants (ferrosilicon)
Inspection: Factory testing of raw materials to ensure proper element composition

Smelting Process

Charging: Proportional loading of materials into smelting furnace (cupola/electric furnace)
Temperature control: 1450-1550℃ melting temperature for uniform composition
Composition adjustment: Continuous monitoring and adjustment of carbon, silicon and other elements

Spheroidization and Inoculation

Spheroidization: Adding 1-2% spheroidizing agent to transform graphite structure
Inoculation: Adding 0.3-0.8% inoculant to refine graphite balls

Casting and Molding

Mold preparation: Sand molds with good air permeability
Temperature control: 1350-1450℃ pouring temperature with moderate speed
Riser chill: For solidification shrinkage compensation

Cooling Process

Natural cooling in mold (hours to days depending on size)
Controlled cooling speed to optimize material properties

Post-Processing

Sand cleaning: Mechanical or manual removal of impurities
Cutting/grinding: Surface finishing for smoothness
Heat treatment: Annealing, normalizing, quenching for improved properties
Anti-corrosion: Asphalt paint, galvanizing, or thermal spraying

Quality Inspection

Appearance: Checking for cracks, pores, and dimensional accuracy
Performance: Mechanical testing per EN124 standards
Spheroidization rate: ≥80% graphite spheroidization required

Packaging and Storage

Plastic film or carton packaging for protection
Organized storage by specifications awaiting shipment
