China’s first self-designed and manufactured export nuclear power ring crane passed the acceptance test

The Dalian Heavy Industry and Crane Group independently designed the independently manufactured circular crane for the second phase of the Chashma Nuclear Power Plant in Pakistan to formally pass the factory acceptance on May 16. It is understood that this is China's first self-designed and manufactured export nuclear power ring crane, which indicates that China's equipment manufacturing industry has become one of the important equipment component markets for international nuclear power engineering.
Pakistan's Chashma 30-watt kilowatt nuclear power plant is a key project for cooperation between China and Pakistan and is known as a model of "South-South cooperation." In 1996, Dalian Heavy Industry·Guangzhou Group and German PHB Company jointly designed and independently manufactured and exported the first 300,000 KW nuclear power ring crane to the first phase of Chashma Nuclear Power Plant. The technical level and quality were well received by users. Signed a contract for the re-manufacturing of a 300,000-kilowatt nuclear power ring crane for the second phase of the project. Today, the factory acceptance is the 250/100+10T nuclear power ring crane for the second phase project independently designed and manufactured by Heavy Industry and Crane Group. The hanging track has a diameter of 33.6 meters, a lifting weight of 250,000 kilograms, and a lifting height of 33 meters. The ring crane is located at the top end of the nuclear reactor building and is used for the lifting service of equipment maintenance in the reactor building during the installation and operation of the power station equipment. The requirements for technical level, quality and precision are very strict.

Galvalume Steel Coil

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC. The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.From the point of view of the degree of coating, the Galvanized Steel Coil is mainly the zinc plated on the coating, while the coating of the galvalume Steel Coil not only has zinc, but also has an extra part of aluminum.Galvalume steel sheet (coil) has better atmospheric corrosion resistance.

Galvalume Steel Sheet has excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Steel Sheet; the surface has beautiful spangles, which can be used as building exterior panels.

The corrosion resistance of "Galvalume Steel Coil" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
