JFE Steel Corporation has developed an "endless hot rolling process" which makes continuous hot rolling possible at the No.3 Hot Strip Mill in East Japan Works (Chiba). This enables us to manufacture ultra thin-hot rolled steel sheet in coil under 1.2mm in thickness, which was formally able to produce only via the cold rolling process.

A gradual recovery in consumption is reported, in Denmark, supporting a modest price increase for hot rolled coil, in October. In Sweden, the trend in demand varies by sector, with sales to manufacturers of pumping equipment and forklift trucks falling very little during this year's difficulties.

Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.

Over the years we have gained a good reputation for products suitable for applications when fatigue strength, toughness and wear resistance are critical. As well as meeting specif

Mar 29, 2020· Hot-rolled steel features. The hot-rolling process occurs at temperatures above 900°C. Since the metal heats up, it is much easier to give it the necessary shape. Hot-rolled mill products are usually cheaper than the cold-rolled due to the fact that hot-rolled steel does not require re-heating (as in the case of cold rolling).

MILL LIMITS Hot Rolled Steels are available in thicknesses of 0.071 – 0.525 in. (1.80 – 13.34 mm) and widths of 30 – 80 in. (1016 – 2032 mm), depending on dimension and product quality. For sizes outside of these limits, please contact your AK Steel sales representative.

Slabs are the feed material for hot strip mills or plate mills and blooms are rolled to billets in a billet mill or large sections in a structural mill. The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators.

The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a …

Hot-rolled metals generally have little directionality in their mechanical properties and deformation induced residual stresses.However, in certain instances non-metallic inclusions will impart some directionality and workpieces less than 20 mm (0.79 in) thick often have some directional properties. Also, non-uniform cooling will induce a lot of residual stresses, which usually occurs in ...
