Scope of Work

The metal components crafted for this ferronickel project encompassed a variety of structures, prominently featuring ducts and duct supports. The materials utilized included Q355B and Q235B steel with thicknesses ranging from 4mm to 40mm. The fabrication process embraced a series of intricate procedures, such as cutting, edge milling, bending, welding, and painting. Each step was meticulously executed to ensure the final products met stringent quality standards.

Fabrication Process

The project commenced with a detailed planning phase, where the team at Openex meticulously analyzed the project requirements and devised a comprehensive strategy. Drawing decomposition, process splitting, and welding operations were intricately planned to optimize efficiency and minimize any potential bottlenecks in the production process.

Cutting-edge technology and precision machinery were employed in the fabrication process. The raw materials, Q355B and Q235B steel, were subjected to cutting processes to achieve the specified dimensions. Following this, edge milling and bending operations were carried out with utmost precision to ensure the accurate alignment and structural integrity of the components.

Welding, a critical phase in steel fabrication, was executed with the highest standards of craftsmanship. Openex's skilled welders meticulously joined the steel components, ensuring the structural integrity and durability of the final products. Post-welding, the components underwent a thorough inspection to guarantee they met the required specifications.

The final touch involved the application of protective coatings through a meticulous painting process. This not only enhanced the aesthetic appeal of the components but also served as a crucial layer of defense against corrosion, especially given the nature of the ferronickel environment.

Project Execution

The project unfolded seamlessly, with every aspect of the production process carefully monitored and managed. Drawing on their extensive expertise, the Openex team adeptly decomposed the intricate project drawings, streamlining the subsequent processes. Process splitting, a key strategy in managing complex fabrication projects, was implemented effectively, allowing for parallel execution of tasks without compromising quality.

The welding operation, a pivotal stage in the fabrication process, was carried out with precision and efficiency. Openex's team of experienced welders ensured that every weld joint met industry standards and adhered to the project specifications. This meticulous approach not only contributed to the overall quality of the components but also played a crucial role in completing the production schedule ahead of the planned cycle.

Despite the project's complexity, Openex's commitment to excellence and efficient project management enabled the completion of key components well before the scheduled timeline. This not only showcased the company's prowess in meeting project deadlines but also demonstrated its ability to navigate challenges effectively.
