TO 31 Strip and plate

Jernkontoret's technical area 31, Strip and plate, is where collaboration takes place between companies, research institutes, higher education institutions interested in research into the rolling of flat products.

Rolling of wide strip. 

The rolling process for production of strip or plate – often called flat products – normally starts with the reheating of steel slabs in furnaces. The steel slabs are then hot rolled into strip or plates, via repeated thickness reductions, both reversible and continuous, using a number of roll pairs. 

The products are then water-cooled in a cooling area or undergo hardening. The interaction between the heating, rolling and cooling creates the product’s final external and internal properties. For some of the products, cold rolling and annealing is carried out while otherwise finishing takes place e.g. cutting into sheet.

There are a large number of different rolling mills for hot and cold rolling. Examples include the wide strip mill, plate mill, reversible finishing mill, tandem mill, sizing mill, cluster rolling mill, etc.

The products, both of carbon steel and stainless steel, are found in a large number of applications. These typically include cars, commercial vehicles, heavy transport vehicles, ships, cranes, buildings, white goods, kitchen utensils etc. 

Committee meetings are arranged 2-3 times per year, at Jernkontoret and at member companies alternately.

Purpose and general orientation 

  • To seek financing for, to plan and initiate own projects, as well as externally co-funded projects or major research programmes, via co-ordinated contacts between companies, researchers and donors
  • To run this process-focused research, with an input of joint research efforts from companies, institutes and higher education institutions
  • To foster contacts within the industry, facilitate the sharing of experiences, to make the best use of specialist knowledge and monitor the latest technology and processes
  • To strengthen the Nordic steel industry’s competitive position within this area through applying the research results obtained
