A few days ago, the stainless steel hot-rolled products produced by SXTG Advanced Materials Technology Group have been successfully applied to the liquid nitrogen thermostat storage tank project of China’s first extremely deep underground laboratory expansion project.
SXTG Dedicated to R&D and manufacturing of high-performance stainless steel,copper clad stainless steel composite plate and stainless steel extrusion parts…
After participate in the “ITER Project”, it successfully assisted the construction of major scientific research projects again.
China’s extremely deep underground experiment is 2,400 meters deep, which is the world’s deepest underground laboratory and belongs to China’s major scientific and technological infrastructure projects. Its completion signifies that China has a world-class clean low-radiation research platform that can independently carry out international cutting-edge basic research topics such as particle physics, astrophysics, cosmology, and dark matter detection.
As one of the important equipment, the liquid nitrogen thermostat storage tank can provide a low temperature working environment and shield radiation for the detectors placed in the underground laboratory.
In 2018, ZGZJ Group successfully won the bid for this project, relying on its brand awareness in the cryogenic equipment industry. As a strategic partner, SXTG fully assists ZGZJ Group to complete the material supply of liquid nitrogen thermostat storage tanks. The biggest technical difficulty of the project is to solve the impact of the underground limit air humidity environment on the quality of the storage tank. It has extremely high purity of stainless steel products, corrosion resistance under low temperature conditions, weldability under low temperature wet and cold environments, and low temperature mechanical properties. Claim. Through many field surveys and communication, the technical personnel of both parties formulated measures to adjust the composition, improve the purity of the smelting, and control the precise process based on the current stainless steel hot-rolled coil (plate) production process to ensure the reliability of the supply of materials. After many experiments by production technicians and repeated adjustments to the process, the task of supplying this batch of products was successfully completed.
Beginning in 2007, SXTG has successively provided a series of products such as completely austenitic stainless steel cold-rolled plates, medium-thick plates, composite plates, profiled materials, forgings, steel pipes, etc., for the international major scientific and technological project “ITER”, most of which are applied to poles. It is a cutting-edge product that can withstand complex mechanical and electromagnetic forces under low temperature and strong magnetic fields. Today, SXTG stainless steel hot-rolled products are once again used in the construction of China’s first extremely deep underground laboratory. They have withstood the extremely high test of 2,400 meters underground in the cold and humid environment, which is the fruit of SXTG’s continuous promotion of high-quality transformation and development.
