Surface depression of continous casting slab or billet
Continuous cast slab or billet surface shows irregular pits, which are mostly lateral pits, as well as vertical pits. Depression and more in austenitic stainless steel (Cr18Ni9 type) and a low-carbon steel (carbon 0.10 to 0.15%) of the slab surface. Depression is easy to produce in the lateral su...Read more -
Spiral steel pipe temperature control and installation process
Spiral steel pipe temperature control Spiral steel pipe welding temperature is mainly affected by the high-frequency eddy thermal power, high-frequency eddy current heating power is mainly affected by the frequency, power and thermal eddy current excitation frequency is proportional to the square...Read more -
Seamless steel pipe piercing
Piercing is the first step of hot-rolled seamless steel pipe deformation, and its role is to solid hollow tube billet dressed as capillary. Due to wear a capillary surface defects or eccentric (uneven thickness) is difficult to eliminate or reduce the deformation process, therefore, the quality o...Read more
