Xingsteel successfully developed a super pure iron DT4C wire, by a number of customers to use the report information feedback: the material is not only low residual elements, high cleanliness, cold upsetting performance is good, and coercive force standard is significantly better than the national standard requirements. DT4 belongs to…

Frontier scientific problem How to achieve low energy artificial intelligence? How to achieve maneuvering in the upper atmosphere? Can the new coincidence measurement method search for the existence of magnetic monopole and axionic dark matter? Do nonlinear effects vary with scale? What are the basic scientific issues affecting the development…

The transverse cracks on the surface of continuous casting billet are located at the trough of the vibration mark on the inner arc surface of the billet, which is usually hidden and invisible. After pickling, it can be found that the crack depth is up to 7mm and the width…

In strip steel line most popular cooling mode is laminar cooling. Pressure injection cooling is characterised by continuous jetting of water, good directionality cooling efficiency is not high, serious spattering, there is high requirements to water quality. Aerosol cooling with gas will be atomised water, its cooling capacity is very…

In production operation, some methods are useful for increasing the life of roller ring, if the operators pay attention on need to know correct To select suitable roller rings The hardness and wear resistance of the roll ring comes from tungsten carbide, while the toughness and strength depend on the…

Many cracks on the wire surface are caused by the transverse and longitudinal cracks of billets and rolling process, that can reduce the generation of cracks on wire rod surface through the control the quality of raw materials and proper rolling operation procedure. 1 Billet surface longitudinal cracks, transverse cracks…

A new type of tundish adopts a double shell inclusion and cover with vacuum insulation function, and is supplemented by anti-oxidation coating heat insulation technology and permanent layer castable with low thermal conductivity. The original intention of its research and development is to use the principle of vacuum insulation to…

Support rolls refer to the rolls that can increase the rigidity of the work rolls and directly or indirectly bear the rolling load, which is an important part to prevent the work rolls from flexural deformation and affect the quality of plate shape. Support roll body to withstand a lot…
