On November 4th, the world's first 5G remote-controlled bulldozer SD52-5E delivery ceremony was held in the Jiangmen Group's Chengmenshan Copper Mine. Mr. Zhang Min, Party Secretary and General Manager of Shantui Co., Ltd. attended the ceremony.
Zhang Min pointed out in his speech that the SD52-5E jointly developed by Shantui and Jiangtong Copper Group is the first application of the world's first 5G remote-controlled bulldozer in mining production, and escorts Jiangtong “Smart Mineâ€. We will do 100% of our efforts to ensure high equipment attendance and low failure rate, and implement the core values ​​of “Customer Satisfaction is our aimâ€.
It is reported that Shantui’s first equipment has been stationed in Jiangtong Group since 2003. In the past 16 years, many equipments have been served in the various copper mines. Shantui equipment has been working together with the mountains, and it is hard work. . In particular, in recent years, the SD52 high-powered bulldozers have successively entered the two major mines of the Jiangxi Copper Group, which has opened a new chapter in cooperation between the two sides.
Shantui SD52 high-powered bulldozer has reliable performance and excellent quality. It can be said to be specially developed for the mine. After the blessing of 5G technology, it is believed that it will add a “construction tool†to the operation project.
After the meeting, Zhang Minyi visited the construction site of Jiangtong Copper. The two sides discussed and exchanged in-depth discussions on integrated construction, which laid the foundation for the follow-up strategic cooperation between the two sides. (This article is from Shantui)
New magnetic materials to meet the material in different service environment applications. Phase MAX is A kind of nano-layered transition metal compound with hexagonal lattice structure, the molecular formula is Mn+1AXn, (where M is generally A pre-transition metal, A is mainly A 13-15 main group element, X is carbon or/and nitrogen, and N takes the value of 1-3), 1.
From the bonding characteristics of the MAX phase lattice, the electron cloud overlap between M and X atoms determines the strong ionic bond and covalent bond, while the electron cloud overlap between M and A atoms is weak, which is helpful to reflect the physical and chemical properties of A element. Therefore, if magnetic elements are introduced into the A position of MAX phase, it is expected to be used as functional materials in spintronic devices with unique nano-layered structure, high stability and adjustable anisotropy. However, previous studies have generally believed that post-transition metal elements such as Fe, Co, Ni and Mn with 3D electrons should exist in the M atomic lattice site of MAX phase materials. It is considered to be A great challenge to synthesize magnetic elements to occupy the A site of two-dimensional monatomic layer in MAX phase.
