On January 21, 2021, China`s leading manufacturer of wide-width stainless steel strips, ZJYJ Metal Materials Technology Group and Nanjing University of Science and Technology jointly completed the "Ultra-wide and ultra-thin precision bright stainless steel strip key technology and industrialization" project won the province of 2020 First prize for science and technology.
After more than ten years of long-term research, the project has broken through the key technical bottleneck of the bright surface and ultra-wide and ultra-thin stainless steel belt from the basic principles of oxidation-reduction, deformation and phase change. The equipment has realized large-scale production and formed a major original breakthrough from basic theory, key technology, core equipment to industrialization.
Precision stainless steel belts are widely used in aerospace, electronics, construction and decoration, petrochemicals, environmental protection equipment, precision instruments and other fields. They are indispensable key materials for economic construction and national defense. Stainless steel has many types of alloy elements, high content, large deformation resistance, difficult rolling, and the shape and control of the width, thickness, surface quality and structural properties of the strip are mutually restricted and difficult to coordinate. Precision stainless steel strips have long been dependent on imports. As the company overcomes the key technology of ultra-wide and ultra-thin precision bright stainless steel belts and realizes industrialization, this is of great significance to scientific and technological progress, social development and national security.
