1.Introduction
Metallurgical industry has always been an important branch of China’s heavy industry. In order to meet the needs of national economic development, the construction of large-scale metallurgical plant requires a lot of steel structure. Therefore, the requirements for the production technology of steel structure of metallurgical plant are very strict. This paper analyses the technology of steel structure manufacturing in metallurgical plant.
2.Steel Structure Manufacturing Technology
2.1 Raw Material Preparation
Steel structure manufacturing technology of metallurgical plant mainly includes raw material preparation, cutting, welding, inspection and installation.
Raw material preparation is the first step before manufacturing steel structure of metallurgical plant. In order to ensure the production process, it is necessary to choose high quality raw materials. Metal components must be marked and identified according to the drawings and the labels should be checked carefully before unpacking.
2.2 Cutting
In the cutting process, it is necessary to choose different cutting processes according to the actual situation. The commonly used cutting process includes flame cutting, plasma cutting, shearing, sawing and milling.
2.3 Welding
For steel structure of metallurgical plant, manual welding and full-automatic welding are two common welding technology. Straight welding process is adopted for flat plate and angle steel, flame welding technology is adopted for pipe material, and TIG welding is adopted for thin plate and special shape parts.
2.4 Inspection
After finished welding, the dimensions and positions of the welding parts must be inspected to keep them in compliance with the relevant technical documents. The Welding Quality System must be established and the welders qualification documents and personal working experience must be inspected.
2.5 Installation
Installation is an important link in the construction of metallurgical plant. The lifting and installation of steel structure must follow the construction drawing, safety regulations and technical requirements. The installation must be steady and reliable.
3.Conclusion
Steel structure manufacturing technology of metallurgical plant requires extremely strict control in all aspects. From the actual situation, we can see that the production technology of steel structure is complex and comprehensive. All aspects of the technology must be strictly inspected.
