Rotary drilling, tying irrigation worry-free, lower steel cage, concrete pouring...... The construction of Xiongshang high-speed railway XSZQ-02 section by the 14th Bureau of China Railway is in full swing. The contractor carefully controls the material quality and construction process, and specially selects Xinda brand rebar with good flexibility, high strength, corrosion resistance, low temperature performance and strong seismic performance to participate in the project construction.

The Xiongshang high-speed railway involved in this project is an important component of Beijing-Hong Kong (Taiwan) passage of the "Eight vertical and eight horizontal" high-speed railway of China's high-speed railway network. It is an important infrastructure that supports and leads the in-depth development of the three major strategies of "The Belt and Road", "the coordinated development of Beijing, Tianjin and Hebei" and "the Yangtze River Economic Belt", helps build the millennium plan of "Xiongan New Area" and promotes the social and economic development of the regions along the line.
Xiongshang high-speed Railway is located between the Beijing-Shanghai high-speed railway and the Beijing-Guangzhou passenger line, basically along the existing Beijing-Kowloon Passage, starting from the Beijing-Xiong Intercity Xiongan Station in the north, passing through Xiongan New District of Hebei Province, Cangzhou City, Hengshui City, Xingtai City and Liaocheng City of Shandong Province in the south, crossing the Yellow River in Taiqian County of Puyang City in Henan Province, and then passing through Jining City, Heze City of Shandong Province, Shangqiu City of Henan Province to Shangqiu Station of Shanghehang Railway. The total length of the line is 551.97 kilometers, passing through 3 provinces, 9 cities and 25 counties (districts).

Innovative brand to expand market space

Struggle, is our lasting power; Innovation is our unremitting pursuit. Xinda always regards independent innovation as the strategic support of enterprise development, and takes research and development as the inexhaustible driving force to build the brand of Xinda. Xinda has stepped out of a road of brand strength relying on innovation to reach the peak. HRB400(E), HRB500(E) and other high-strength high-seismic steel bars for building flexion ratio are mainly produced by the new alloy nitriding precipitation strengthening process and grain refining strengthening process in Xinda rebar.

In recent years, Xinda has made new breakthroughs in a number of independent research and development achievements and technology, high-strength seismic steel HRB500Eφ40mm test rolling success, the product performance indicators are in line with the requirements of the national standard, the product to implement no tension control rolling, to ensure high quality precision; The rough, middle and finishing mill groups are all short stress line mills without arch, horizontal frame hydraulic transverse movement, vertical frame hydraulic lifting; Hydraulic motor regulating roll seam, computer two-stage model control. By adopting various key technologies, the surface quality, dimensional tolerance, mechanical properties and other indexes of building steel products are all stable up to national standards.

In Hebei Province, it takes the lead to produce high-strength HRB500E by microalloying + controlled rolling and cooling technology. At the same time in Tangshan iron and steel enterprises, take the lead in the new national standard production of reinforced concrete with hot rolled ribbed bar, for the whole industry's high quality development has played a demonstration role. The control process of post-rolling cooling was developed in cooperation with Northeastern University to ensure that the microstructure of high-strength bar steel is ferritic and pearlite, and there is no harmful microstructure and tempered martensite.

Quality brand enabling boutique strategy

Quality is the life of an enterprise and the foundation of its survival and development. Hebei Xinda Group has always been adhering to the strategy of "brand strong enterprise", taking stable, good and excellent product quality as the cornerstone to establish a foothold in the market, winning high recognition in the industry, and establishing a reputation at home and abroad as the "golden sign".

High quality products behind a huge set of quality management system support, Xinda brand rebar has obtained the "National Industrial product production license" and passed the ISO10144 quality system certification, national metallurgical products MC certification, Korea KS certification, the establishment of a complete quality management system and the national CNAS recognized quality testing center, To control the whole life cycle of products strictly in accordance with national and industry standards, Won the construction steel quality brand Demonstration Base, China Excellent steel enterprise brand, National Quality inspection trustworthy products, China Quality Inspection Association group member units, National steel industry quality leading brand, national quality inspection stable qualified products, national quality inspection integrity enterprise, national quality integrity Benchmarking enterprise, private enterprise construction steel Top Ten quality brand enterprises, etc.

At present, Xinda brand rebar products are mainly placed in East China, North China, northwest markets, Jiangsu and Zhejiang areas; South China market, Guangdong, Fujian area, widely used in Beijing Daxing International Airport, Tianjin National Convention and Exhibition Center, Tsinghua University Park, Changchun makeshift Hospital, Ningbo Metro and other key projects.

Quality is a kind of consciousness, a kind of quality and a kind of responsibility. Hebei Xinda Group will continue to improve the quality management system of full participation, full business coverage and whole-process tracking, further improve the quality of operation and development, support the industry first-class with product excellence, forge the industry first-class with brand excellence, lead the industry first-class with innovation, and consolidate the industry first-class with modern governance. To build Xinda into a first-class modern large steel group with strong core competitiveness, innovative resilience, enterprise cohesion, social influence and sustainable development!
