TO 32 Bar and profile
Jernkontoret's technical area 32, Bar and profile, is where collaboration takes place between companies, research institutes and higher education institutions interested in research into the rolling of bars and sections, often called long products.
Hot rolling of bars, roughing train.
The rolling process to make bars (billets) and profile products starts conventionally with the reheating of steel slabs in furnaces. It continues with hot rolling of these steel slabs, via repeated area reductions, first reversibly and then continuously through passes between grooved rolls in a number of roughing stands into bars or profiles.
The products are subsequently air cooled on a cooling bed; there then takes place finishing, such as straightening and turning. The interaction between the heating, rolling and cooling creates the product’s final external and internal properties. Rolling mills are long and are divided up into the roughing stand, intermediate stand and finishing train.
Rolling mills are often designated according to the products they make; rod and bar mill, section rolling mill, small section mill, wire rod mill etc. The products are often used as structural elements in buildings (universal beams, structural columns), for bridges, ships and for use in different vehicles.
Committee meetings are arranged 2-3 times per year, frequently on the premises of member companies.

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
