Hot extrusion offers substantial advantages in comparison with hot rolling, forging or machining.See all results for this questionsp.info How is hot steel shaped in a structural mill?In a structural mill there are multiple stands each containing specially shaped rolls where the full set of rolls gradually shape the hot steel in successive passes through separate roll gaps. The product passes through each roll gap only once.See all results for this question

How are flat products supported on hot steel?


How are flat products supported on hot steel?

For flat products, two horizontal rolls are set one above the other in an open housing. These work rolls that contact the hot steel are often supported by larger diameter rolls to prevent them bending under the rolling loads to ensure a uniform thickness product.See all results for this questionsp.info When to use hot rolled or cold formed steel?In thick- nesses available (usually 0.060 to ½ in), hot-rolled steel usually costs less to use. Cold-rolled steel is used in the thinner gages or where the surface fin- ish, mechanical properties, or more uniform thick- ness resulting from cold reducing are desired.See all results for this questionsp.info HOT EXTRUDED SPECIAL STEEL PROFILESHot extruding During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, is pushed through a forming die into a profile bar using a ram with an extrusion force of 2,200 t.
