Ruzhou Qingyuan Industrial Co., Ltd. Was established on May 1, 2012, located in the middle section of Industrial Avenue, Ruzhou Industrial Agglomeration Zone, with a registered capital of 13 million yuan. The company initiated the "Yufa Gai Investment [2010] No. 530" project at the Provincial Development and Reform Commission in 2012, designing a steel wire production line with an annual output of 36000 tons for prestressed concrete. In May 2013, it was granted a production license by the General Administration of Quality Supervision, Inspection and Quarantine and successfully put into operation; In 2019, the project was approved by the National Development and Reform Commission with approval number 2019-410482-33-064032 for an annual production of 4000 tons of precision special-shaped steel wire. It was put into operation in 2021 and passed the acceptance inspection. Ruzhou Qingyuan Industrial Co., Ltd. Is a production-oriented enterprise specializing in the production of metal products. Since 2016, it has been cooperating with Zhengzhou Metal Products Research Institute of China Steel Group. Currently, it is the production base of elastic materials for Zhengzhou Metal Products Research Institute of China Steel Group, forming a strategic partnership.

Leading products:

1. Steel wire for prestressed concrete.

This product complies with national standards (GB/T5223-2014) and corresponding standards of other countries. Its main application scope includes railway cement sleepers, prestressed concrete poles, large high-pressure water conservancy pipelines and seismic pipes, prestressed concrete hollow floor slabs, etc. It is a national energy conservation and emission reduction project in the 13th Five Year Plan. This product has excellent performance, greatly improving the performance of cement products while saving a lot of steel for the country.

2. Oil quenched and tempered spring steel wire.

We mainly produce steel wires with fine specifications (diameter 0.5-2.0mm). Oil quenching tempering treatment, also known as quenching and tempering heat treatment, is the process of quenching and tempering steel wire that has been cold drawn to a specified size. The steel wire has a tempered martensite structure, good strength and toughness, high fatigue limit, and good thermal stability, which are significantly better than traditional cold drawn spring steel wire. It is an ideal material for manufacturing automotive valve springs and suspension springs, and is the main product that replaces imported from Japan in China.

3. Carbon spring steel wire for important purposes.

This product is mainly produced in cooperation with the Elastic Material Branch of China Steel Institute, using 65MN, 82B, 70 # as raw materials for steel wire products. The product is characterized by good plasticity and strong elasticity, and is widely used in various automotive cushions, machinery manufacturing, torsion springs, tension springs, electrical equipment, and sports equipment industries.

4. High quality carbon structural steel wire.

Mainly produced from raw materials such as 10 #, 20 #, 25 #, 45 #, etc., used for automotive seat frames and other structural components.

5. Precision special-shaped spring steel wire for internal combustion engines.

With the development of the domestic automotive industry, agricultural machinery, and large construction vehicles, the original cast sealing rings are too outdated, and the price of imported sealing rings is too high. This product is widely used in engine piston rings, steel rings, valve wire springs, etc. It has the advantages of light weight, small size, uniform elasticity, and low friction coefficient, completely replacing the original casting sealing rings and imported products.
