ROLLING The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control
Skinpass rolling mill Leveler. After the surfaces of the base metal are cleaned, the coils are immersed in a molten zinc bath to provide the zinc coating. The coating mass is adjusted by a gas wiping system immediately after the hot-dip galvanizing. DURGRIP is subjected to lubricating film-coated treatment or chromate-free treatment as required.

The study of power quality (PQ) has gained relevance over the years due to the increase in non-linear loads connected to the grid. Therefore, it is important to study the propagation of power quality disturbances (PQDs) to determine the propagation points in the grid, and their source of generation. Some papers in the state of the art perform the analysis of …
The rolling elements transmit loads from one bearing ring to the other in the direction of the contact lines. The contact angle is the angle formed by the contact lines and the radial plane of the bearing. 0 refers to the nominal contact angle, i.e. …

cooling, yet still hot, malleable shapes from casting to the rolling mill. A billet or slab crane is usually an Electric Overhead Traveling (EOT) crane that is very maneuverable. It needs to travel the long distance between the melt shop and the rolling area. It can move the hot, soft metal from the casting area into storage if needed.

In cold rolling of a seamless metallic tube with a cold pilger mill, when a reduction ratio of an outside diameter becomes excessive in comparison to a reduction ratio of a wall thickness, strain in a circumferential direction on flange regions becomes excessive. As a result, compressive stress in a circumferential direction becomes excessive, so that wrinkle imperfections are …
