Recently, breakthroughs were made in the research and development of Baosteel's high-performance mechanical structural steel and its key technologies, and successfully trial-produced 100 kilograms of easy-to-weld ultra-high-strength steel Q890CFD and 120 kilograms of easily-welded ultra-high-strength steel BWELDY1100QL2. These two major steel grades have been successfully developed for the first time in China and will play a role in strengthening and lightening the domestic coal mining machinery.
In recent years, coal and metal ore mining projects have vigorously developed new types of equipment for extracting, lifting, and washing, focusing on the localization of electric traction shearers, hydraulic supports, and other equipment. The demand for high-strength steel and wear-resistant steel has continued to grow, and has grown Mining height, super support, light weight loss direction development.
In order to better serve the technological progress of China's construction machinery, coal mining machinery and port machinery, and meet the requirements of market development, Baosteel has exerted its advantages in equipment, R&D and services in recent years, and has actively developed strategic cooperation with users to form a structural design. , R & D, processing and manufacturing, service and operation of the Quartet cooperation relationship, Baosteel R & D and manufacturing capabilities have been recognized by users.
This year, in response to Shenhua’s 7-meter super large mining hydraulic support project, a research and development team consisting of the Baosteel Heavy Plate Division, Manufacturing Department, Steelmaking Plant, and Baosteel Research Institute actively intervened, and launched a trial production of 100 kilograms of easy-to-weld ultrahigh-strength steel Q890CFD. Developed the TMCP plate shape control scheme for ultra high strength steel, implemented the consistent system technology and optimization of high manganese low carbon steel continuous casting process, carried out laboratory research, and research on process design and user technology, and conducted key technologies such as alloy design and welding process Tackling the problem, the successful trial production of Q890CFD ultra-high-strength steel is easy to weld, and its performance fully meets the needs of users. It is reported that the steel application can replace the Q690CFD and it is expected that the equipment can be reduced by 15%.
In recent years, the construction machinery manufacturing industry is in urgent need of high-strength, large-scale equipment. The leading enterprises in the machinery industry such as Sany Heavy Industry, China United and XCMG proposed the idea of ​​using 120kg super-high-strength steel to enhance the performance of their products. For this reason, Baosteel has worked closely with customers to develop two specifications of 120 kilograms of easy-to-weld ultrahigh-strength steel. The performance index is comparable to similar foreign products.
