On the morning of October 13, 2019 Zhengzhou International Marathon gave opening shoots in the Ruyi Lake, CBD, Zhengdong New District. This event was the “Running China” series of activities for the 70th anniversary of the Fouding of the People's Republic of China. There were 26000 participants ZQS700L cold forming automobile structure steel from 32 countries and regions including China, the United States, Italy, Russia, Spain, Ethiopia, and Kenya to witness the vicissitudes of "International Zhegnzhou". In the fierce competition, the Africa players once again showed their super strength and won the men’s and women’s full marathon championships.

The smelting of ZQS700L cold forming automobile structure steel, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to have high purity. The content of sulfur, phosphorus, oxygen and nitrogen should be low, and the uniformity and stability of steel should be good. The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, spring steel must also have some characteristics.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with ZQS700L cold forming automobile structure steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
