Lean non-oriented electrical steel grades

 · In a Steckel mill the final rolling from about 30 mm to the final strip thickness of about 2.5 mm is carried out in one reversing stand with coil furnaces at each side. Compared to the tandem mill the final passes takes much longer time and are carried out at a fairly constant temperature.

Roughing Mill

Finishing mill rolling of reheated slab: The finishing mill usually has five to seven finishing roll stands, which reduce the thickness of the transfer bar down to the gauge required. The rolling speed is set to allow the last stand to perform the final reduction at the finishing temperature, to achieve certain mechanical properties in the hot rolled strip.

Grade 250 can be produced on either the Plate Mill in flat plate form (AS/NZS 3678 - 250 XLERPLATE®*), or the Hot Strip Mill in coil form (AS/NZS 1594 - HA250 XLERCOIL®). The different production routes can lead to differences in the properties and performance of the two grades, and these differences can be important in certain applications.

A short study on sheet steel specification syntax, Part I

To account for the different mill processing and output properties, ambient-temperature coated products and elevated-temperature coated products typically have different specification requirements. While ASTM A1008/A1008M is used for uncoated low-carbon steels, ASTM A653/A653M is used for hot-dipped galvanized low-carbon steels.
