Technology Research and Development of Tianjin Zhongzhong Technology Engineering Co., Ltd.

In the past ten years, the company's technical center has made great progress, accumulated a lot of design experience, emerged a group of talented people who are committed to the research of metallurgical machinery, and completed a number of leading domestic and international advanced technological achievements. In 2004, it was named Tianjin Enterprise Technology Center. The center consists of mechanical design room, hydraulic lubrication design room, electric transmission design room, process design room and new product design room. Engineering and R&D personnel 102, including 35 personnel with senior titles or above. The technology center has formed a technological innovation system of "production generation, trial production generation, research and development generation and conception generation", and formed a market-oriented technological progress mechanism integrating scientific research, development, design and production. In recent years, we have designed and manufactured many products with independent intellectual property rights on the basis of digesting and absorbing advanced technologies at home and abroad. After continuous innovation, the self-developed finishing equipment and collection area for hot rolled strip have become well-known products in domestic hot rolled strip production lines. Widely used in hot rolled strip production lines such as plain carbon steel and stainless steel.

In 2005, Zhongjing Science and Technology designed and manufactured the first domestic stainless steel 1 150 hot rolled wide strip steel production line. By using finite element analysis and computer simulation technology, the overall structure of the production line is optimized, and full hydraulic screwdown, AGC thickness control and hydraulic roll bending are realized, thus the thickness difference and shape of strip steel are reliably controlled and the quality of strip steel is improved. Some technologies have filled the domestic gap.

In 2007, the project "Development and Industrialization of Stainless Steel Hot-rolled Broadband Production Line Series" won the "2007 Tianjin Science and Technology Innovation Special Fund" award. The company has realized the serialization of strip steel design and manufacture.

In 2003, China Science and Technology developed and produced the 1070 universal H-beam production line, and the self-developed universal rolling mill with high rigidity and short stress line filled the gap in China. In 2007, our company developed the first 400×200mmH-beam production line in China, and the second-generation universal rolling mill with high rigidity and short stress line independently developed reached or exceeded the imported products, which was recognized as the leading domestic and international advanced technical level in the industry. Since then, our company has successively developed large, medium, light and ultra-light general H-beam production lines with different specifications. Our company has the ability to design and manufacture 100-900mm H-beam production line equipment with different specifications.

In 2008, Zhongjing Technology began to design and manufacture advanced precision titanium alloy plate production lines for Antai Technology and CSIC, which opened up a new field of designing and manufacturing high-end high-quality alloy steel production equipment. At present, the company is developing cold-rolled precision belt equipment with world-leading technology level, and strives to make new breakthroughs in the research and development of high-end equipment technology for cold and hot rolling.

Middle East Science and Technology has won two Tianjin Science and Technology Progress Awards and more than 20 technology patents including two invention patents. The impressive performance has attracted the attention of domestic media. Many media such as China Metallurgical News reported the successful application of China Heavy Industry's independent innovation products.

China Science and Technology has established good cooperative relations with famous universities and research institutes such as University of Science and Technology Beijing, Yanshan University and Iron and Steel Research Institute. In 2008, the company purchased SolidWorks 3D design and supporting finite element analysis software, which improved the design capability. Through computer simulation of stress analysis, stiffness analysis, motion analysis, finite element analysis, simulation prototype, etc. The risk of new product development disappears in the design stage, which greatly improves the research and development ability, shortens the research and development cycle and extends the research and development field.
