The material of marine flat bulb steel is usually structural steel, and common materials include carbon steel and alloy steel. The main process of manufacturing marine flat bulb steel includes the following steps:
1. Raw material preparation: Select appropriate structural steel materials, usually supplied in the form of plates or billets.
2. Cutting and processing: Cut raw materials into required sizes according to design specifications and requirements. Cutting can be done using shears, cutting flames and other equipment.
3. Heat treatment: Heat treatment is performed on the cut material, usually including annealing, normalizing, quenching and other processes to improve the strength and hardness of the material and eliminate internal stress.
4. Forming and cold working: After heat treatment, the material is formed into a flat ball shape. This may involve processing methods such as forging, extrusion or rolling.
5. Surface treatment: Surface treatment is carried out on the formed marine flat bulb steel, such as spray painting, anti-corrosion treatment, etc., to improve its weather resistance and corrosion resistance.
6. Inspection and quality control: Inspection of completed marine flat bulb steel, including dimensional inspection, chemical composition analysis, mechanical property testing, etc., to ensure that the product meets specifications and quality requirements.
7. Delivery and transportation: After completing the quality inspection, the marine bulb flat steel is packed and marked, and delivered and shipped as per customer requirements.
The specific process for manufacturing marine flat bulb steel may vary depending on the manufacturer and product specification, and the above steps are for general reference only.
