Material and Manufacturing

● Cast Iron Main Body: Usually, HT200 gray cast iron is adopted. It has excellent casting properties, enabling the formation of complex T - shaped structures. It features good shock absorption, effectively absorbing the vibrations generated when a ship is moored. It also has certain wear resistance, capable of withstanding the friction of mooring ropes and the erosion of the external environment. Additionally, HT200 is relatively low - cost, allowing for cost control while ensuring performance.

● Anchor Bolts and Connectors: Anchor bolts generally use high - strength steel such as Q345 to ensure a stable connection with the cast - iron main body and reliably transfer the external forces received by the bollard to the foundation structure. Nuts and washers can be made of ordinary carbon steel or stainless steel. Ordinary carbon steel is used in general environments due to its low cost, while stainless steel is used in highly corrosive environments for its good corrosion resistance.

● Auxiliary Materials: Materials such as asphalt and fibers are often used as core fillers. They play a sealing role, preventing water and impurities from entering the interior of the bollard, which could lead to problems such as rusting. They can also act as a buffer when mooring a ship, reducing the friction between the mooring rope and the bollard, thus protecting both the rope and the bollard.

● Melting: The selected cast - iron materials are put into a furnace, such as a cupola furnace or an electric furnace, for melting. During the melting process, parameters such as temperature and chemical composition must be strictly controlled to ensure that the quality of the molten iron meets the casting requirements. The properties of the cast iron are adjusted by adding corresponding alloying elements and inoculants.

● Pouring: When the molten iron reaches the specified temperature and composition after melting, it is poured into the pre - prepared mold. During the pouring process, the pouring speed and quantity should be well - controlled to avoid defects such as misruns, gas pores, and slag inclusions.

● Surface Treatment: Shot blasting is commonly used to remove rust, molding sand, and impurities on the surface by the impact of projectiles, increasing surface adhesion. For painting treatment, anti - rust paint can be selected to form a protective film and prevent the cast iron from rusting. Galvanizing treatment can also be carried out to improve corrosion resistance, especially suitable for humid coastal environments.

1. High - strength Material: High - quality cast iron is selected, featuring excellent compressive and tensile resistance. It can withstand the huge pulling force during ship mooring and is not easily deformed or damaged even in harsh sea conditions.

2. Unique T - shaped Design: The structure conforms to the principles of mechanics, which is convenient for crew members to tie ropes quickly. Moreover, it can evenly distribute the stress of the ropes, reduce rope wear, and extend its service life.

3. Good Corrosion Resistance: Through special anti - rust treatment, combined with the anti - corrosion characteristics of cast iron itself, it can effectively resist the erosion of seawater and sea breeze and work stably in high - salinity environments for a long time.

4. Precise Dimensional Specifications: The production process is strictly controlled, resulting in high - precision dimensions. It is suitable for different specifications of ship ropes, ensuring safe and reliable mooring.

5. Simple Installation Method: The design is concise, and the installation process is not complicated. It does not require large - scale professional equipment, reduces installation costs and construction difficulties, and can be put into use quickly.

Application Scenarios:

1. Large Freight Ports: Container ships and bulk carriers frequently enter and exit. The T-shaped cast iron mooring bollards can withstand the huge pulling forces generated when ships berth and during cargo loading and unloading, ensuring the efficient operation of cargo transportation.

2. Fishery Wharves: A large number of fishing boats dock here. The mooring bollards are sturdy and durable, capable of meeting the needs of frequent mooring and unmooring of fishing boats. Moreover, they are easy to install, enabling fishermen to quickly secure the boats and carry out fishing operations.

3. Construction Sites of Cross-sea Bridges: Engineering vessels need to dock stably for bridge construction and other operations. The mooring bollards can fix the vessels in complex water currents and strong wind environments, providing safety guarantees for bridge construction.

4. Marine Rescue and Salvage Bases: When rescue vessels and salvage ships are operating, the T-shaped cast iron mooring bollards can help the vessels dock quickly, ensuring that operations can be carried out promptly in case of emergencies or salvage tasks and completing the tasks in a timely manner.

5. Marine Tourist Resort Wharves: Sightseeing boats and yachts dock frequently. These mooring bollards are not only practical but also aesthetically pleasing, meeting the functional and aesthetic requirements of the resort for wharf facilities and enhancing the tourist experience.
