    Oral Presentation

    The most demanding operations in the steel industry in regard to bearing lubrication and lifetime of bearings are continuous caster strand guide rolls bearings and Hot Strip Mill Work Roll Bearings.
    They are operating in wet and hot environments causing water spray off or water washout of lubricating greases resulting in ingress of aggressive mill water. This contaminants and water cause...

    Rolling of long and flat product
    Oral Presentation

    A hot rolled steel strip that seemingly comes out as flat after the final rolling pass might potentially end up with flatness issues after it has been coiled. It is not easily understood which mechanisms in the coiling process are causing flatness issues. It is known from a material perspective that a combination of high stresses and temperatures can cause stress relaxations and creep...

  3. 295. Finite Element modelling of skid marks on steel slabs in a walking beam reheating furnace

    Rolling of long and flat product
    Oral Presentation

    Walking beam furnaces are common for reheating of steel slabs to reach temperatures for hot rolling. Inside the furnace, the slabs are carried on water-cooled skids that support and move them through the furnace. The point contact between slab and skid results in undesired cold spots on the slabs, skid marks, which persist to hot rolling of plate/strip; leading to increased deformation...

    Rolling of long and flat product
    Oral Presentation

    In manufacturing of steel products, demand for thermo-mechanical controlled processing (TMCP) is increasing steadily to satisfy various properties. However, defect of shape occurs when the temperature distribution of steel products becomes uneven during the cooling process. As a result, productivity and product yield are decreased. Predicting thermal deformation with high accuracy is essential...

  5. 408. Unbeatable product properties and performance of Danieli's K-Spooler
    Dr Maicol Cimolino

    Rolling of long and flat product
    Oral Presentation

    From the world's first in-line twistless bar winding machine in 2002 to the present, the key features in terms of maximum coiling speed, maximum coil size, and mechanical and metallurgical properties of the Danieli K-Spooler have improved tremendously.
    Achievements have been made that were unexpected at the time. Maximum coiling speed of 40 m/s for 8 and 10 mm rebar, final coil size up to 8...
