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…
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…
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…
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…
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…
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…
Yield strength of fine-rolled rebar refers to the yield limit of fine-rolled rebar when yielding phenomenon occurs, that is, the stress to resist trace plastic deformation. Greater than this limit of external force, will make the parts permanent failure, can not be recovered. The yield strength of fine-rolled rebar are…
1.The components of magnets are iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, itself has a magnetic moment Classification: permanent magnets, soft magnets. Application areas: information storage, used in engines, creative product design, levitation tables, exercise equipment, gravity-sensing concept watches, etc. 2. Spider…
Hot Resource Temperature Manner of utilization 1 Slag Canister The surface of the slag tank keeps the temperature 200℃-300℃ for a long time. Specially designed simple-walled slag tanks for the production of charred wood for wood construction and furniture. Also used for material drying. 2 Baking bag flame Horizontal overflow…
Ultra-low emission technology of flue gas for chain grate machine and rotary kiln pelletizing is one of the national green low-carbon advanced technology achievements, applicable to the flue gas treatment in the process of rotary kiln pellet production. This technology utilizes selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR)…
