Shandong Zhengxiang Industrial and Mining Equipment Co., Ltd. is a perfect non-ferrous metal casting and processing manufacturer, has been committed to the casting and processing of non-ferrous metals for many years. Make full use of the advantages, actively adopt the perfect production process, now to develop into a perfect non-ferrous metal casting factory, our company centrifugal casting production of Marine crane copper jacket.

Marine crane is a ship's own equipment and machinery for loading and unloading cargo, mainly including derrick equipment, deck crane and other loading and unloading machinery. Marine crane is a kind of special crane for carrying out transportation operations in the water environment. It is mainly used for the transportation and transfer of cargo between ships, replenishment at sea, dropping and recovering of underwater operation equipment and other important tasks. The special Marine application environment brings great challenge to the control of Marine crane.

The working characteristic of Marine crane is intermittent movement, and the machinery is always in the starting, braking and positive and negative running state. Although its running speed is not high, but often bear heavy load; And long-term continuous work in dust or seawater wet corrosion and other harsh environment, the equipment must have the characteristics of high efficiency, continuity, stability, reliability, easy maintenance and long life, the corresponding supporting bearing put forward the requirements of low speed, heavy load, high reliability and long life.

The material of Marine crane copper sleeve produced by our company is aluminum bronze 9-4-4-2, casting method is centrifugal casting. CuAl9Fe4Ni4Mn2 cast copper alloy has high mechanical properties, excellent corrosion resistance in the atmosphere, fresh water and sea water have high corrosion fatigue strength, castability is good, good wear resistance, has heat resistance below 400℃, can be heat treatment, good welding performance, not easy to braze. ZCuAl9Fe4Ni4Mn2 casting copper alloy is used for important castings requiring high strength and good corrosion resistance, and is one of the main materials for manufacturing ship propellers.
