Here is a detailed analysis of the core processing techniques for the Outdoor Portable Weathering Steel Fire Bowl Garden Corten Steel Fire Pit, integrating material properties and product functional requirements, covering key steps from raw materials to finished products:

1. Raw Material Preparation

Corten Steel Selection

Use ASTM A588/A242 standard weathering steel coils or plates with a thickness of typically 2–4mm to balance strength and portability.

The material must have excellent thermal formability and weldability to ensure no cracking during subsequent processing.

Surface Pretreatment (Optional)

Hot-Rolled Mill Scale Treatment:
Oxide skin (mill scale) forms on the surface during hot rolling. To accelerate later weathering, the mill scale layer can be retained; to reduce early rust contamination, it can be removed by pickling or shot blasting.

Laser Cutting/Plasma Cutting:
High-precision equipment cuts the plates according to design dimensions to form the fire bowl body, base, handles, and other components.

 

 

 

 

 

 

 

2. Forming Processes

Stamping/Rolling Forming

Fire Bowl Body:
Use stamping dies or rolling machines to process flat plates into arc-shaped bowl structures, ensuring smooth inner walls and uniform curvature for easy wood combustion and heat distribution.

Base and Support Structures:
Weld ring supports or three/four-legged supports, typically using triangular stability structures to ensure the fire pit remains balanced when placed.

Some portable models feature foldable supports connected by hinges or snaps for easy disassembly and storage.

Ventilation Design and Hole Opening

Process circular/bar-shaped ventilation holes on the bottom or side walls of the fire bowl. Precise hole opening is achieved via CNC drilling or laser cutting, with hole diameters typically 10–20mm, evenly spaced to optimize air circulation, improve combustion efficiency, and reduce smoke.
