China Iron and Steel Research Institute Group Co., Ltd. joins hands with Powder Metallurgy Industry Technology Innovation Strategic Alliance (CPMA)

On July 19, 2024, in Qingdao, Shandong, China Iron and Steel Research Institute Co., Ltd. and the Powder Metallurgy Industry Technology Innovation Strategic Alliance (CPMA) jointly hosted the "Hot Isostatic Pressing Technology Innovation Forum" hosted by Iron and Steel Research Haopu Technology Co., Ltd. The forum aims to showcase the latest research and development achievements of China Iron and Steel Research Institute in the field of hot isostatic pressing technology, promote in-depth exchanges and cooperation between experts and scholars at home and abroad, and jointly promote the innovation and application expansion of hot isostatic pressing technology.

The "Fourth Chemical Heat Treatment Forum" was held in Zhengzhou

From June 26 to 28, 2024, the "Fourth Chemical Heat Treatment Forum" was held in Zhengzhou. Researcher Chen Guomin, former chief engineer of Zhengzhou Machinery Research Institute Co., Ltd., Researcher Tong Xiaodong of Beijing Institute of Aeronautical Materials, Senior Engineer Zhu Baizhi, Director of NGC Industry Association, School of Materials Science and Engineering of Tongji University, and Doctoral Supervisor Gao Yukui, Deputy Director of Shanghai Key Laboratory of Metal Functional Materials Development and Application, and 28 other experts and scholars discussed in depth and gave suggestions and opinions on chemical heat treatment technologies such as carburizing, nitriding, and boriding and technical difficulties in actual work. Our group sent General Manager Zhu Jinkai of the group, Director Shen of Shanghai Pengtai Company, and Engineer Zhang of Wuxi Xinchangtai to attend the meeting and study.

Heat treatment process, laser hardening has the following characteristics

The heating speed is extremely fast, the cooling speed is high, and the deformation of the workpiece is extremely small. Because the laser has a very high power density, the laser beam can make the surface temperature rise at a rate of 104~1060C/s when scanning the surface of the material. The material can be heated to the phase change zone in a very short time, and the cooling rate of the material can reach 105 9C/s. The action time of the laser is also very short, so the modified area is limited to the surface of the workpiece, and it is not easy to cause thermal deformation of the whole workpiece.

The 3rd (Suzhou) Commercial Heat Treatment, Hot Isostatic Pressing, Powder Metallurgy and 3D Printing User Conference was successfully held at Suzhou Zhiyin Wyndham Grand Hotel

On March 28-29, 2024, the 3rd (Suzhou) Commercial Heat Treatment, Hot Isostatic Pressing, Powder Metallurgy and 3D Printing User Conference was successfully held at the Suzhou Zhiyin Wyndham Grand Hotel. A total of more than 230 companies and more than 470 representatives attended the conference, including 65 exhibitors. Our group's laser branch successfully participated in the exhibition, and General Manager Dai Xianzhu won the "Heat Treatment Industry Individual Contribution Award"!

Specializing in laser 3D printing and laser surface treatment

Laser cladding, also known as laser coating or laser melting, refers to adding selected coating materials to the surface of the substrate in different filler forms, using a high-energy density (104~10°W/cm2) laser beam to melt it simultaneously with the extremely thin layer on the surface of the substrate, and quickly solidify to form a surface coating with extremely low dilution and metallurgical bonding with the substrate, thereby improving the wear resistance, corrosion resistance, heat resistance, and oxidation resistance of the base surface. Special power construction means that every link from feasibility study, design to construction will be closely centered on the construction and development needs of the port area, which means more meticulous and thoughtful construction and service. At the beginning of 2013, after nearly five years of hard work, the 110 kV Qixing power transmission and transformation project entered the construction stage. Faced with such a rapidly developing island, protecting the environment and saving resources have become the work that Ningbo Electric Power Bureau has tried every means to do well.
