Steel obtained after heating the ingots or billets and leaving them at a temperature higher than that of austenization, by passing the casting product between two rolls or cylinders rotating at the same speed and in the opposite direction, to reduce their thickness by the pressure exerted . The rolled product guarantees a medium dimensional…
DetailsThey are cylinders that rotate in the opposite direction to reduce a section of a product during hot or cold rolling. They must be of a material of great hardness, resistance to wear and undeformability, having to maintain those properties at high temperatures in the case of the rolling mills used in hot rolling.
DetailsThis is the degree of roundness of the straight segment where several faces meet.
DetailsIron oxide generated on the surface of the steel produced by the reaction of oxygen with the metal at high temperatures. Depending on the temperature at which oxidation occurs, the scale may be composed of ferric oxide or ferrous oxide. It is called the primary scale the one coming from the semiproduct before being rolled…
DetailsScraps of waste metal, mainly iron. The scrap used in the steel melting comes mainly from demolition scrap or short ends, chip and rejects from other steel manufacturing processes. The scrap used in the steel plant is classified, in composition and density for the control of the chemical composition of the steel as well as…
DetailsTube that is obtained from a solid piece with cylindrical shape which is heated in a furnace prior to be extruded. It is then deformed with rolls and then the hole is made. It is perfect to contain the pressure due to its homogeneity in all its directions.
DetailsIt is a surface cleaning treatment technique by impact. A correct finish and surface finish can be achieved. It consists of the projection of abrasive particles (shot) at high speed (65 – 110 m / s) which, when impacting with the treated piece, produces the removal of contaminants from the surface.
