In-line control of plate microstructure to achieve near-net mechanical properties requires a combination of the correct time temperature strain path during rolling and accelerated cooling strategy to control the grain size and final material phases. This paper firstly reviews the process routes available to produce thermo-mechanically control rolled steel products using the combination of...

This work examines how edge masking and non‑uniform initial temperature profiles influence steel strip deformation during rapid cooling in endless production. The aim is to support industrial optimization of cooling sections by providing reliable data and validated numerical models. Material properties required for thermo‑mechanical simulations were measured experimentally over a wide...

The control of recrystallization in ferritic stainless steels is critical for tailoring grain size and optimizing toughness, specially for high thickness grades. While the role of niobium (Nb) in delaying recrystallization is well established in austenitic systems, primarily for carbon steels which are usually hot rolled in austenite, its effect in ferritic stainless steels, which can be...

Abstract

The production of high-toughness jumbo structural sections remains a significant challenge in heavy section mills due to low reduction ratios, heterogeneous microstructure, and inconsistent mechanical properties across thick flange regions. These challenges are particularly critical for offshore grades (JR, J0, J2), which require strict toughness compliance according to... -

A very fine ferritic structure is important for achieving the required mechanical properties for high-strength pipe steels during hot strip rolling. Pipe steels are usually produced by thermomechanical rolling with low rolling temperatures during finishing. This rolling practice is demanding on capacity and equipment.

To overcome this problem, an advanced rolling strategy for high-strength... -

Carburised gears have been widely used in various mechanical transmission engineering fields. However, the carburising process is prone to mixed grain defects constraints on the carburising temperature further increase. Uneven distribution of grain will seriously damage the hardness, impact toughness and fatigue strength of gears and other key mechanical properties. The development of new...

Using laser ultrasonic (LUS) measurements, the microstructure of metal can be determined directly in situ. The measurement is non-contact and nondestructive, meaning it can be used for hot and moving samples, meaning microstructure can be determined in many parts of the steelmaking process where other techniques are not viable. The feasibility of inline LUS grain size measurements [1] as well...

Within the present investigation, instrumented drop-weight tear tests were carried out on industrially produced heavy plate material that was thermomechanically rolled using two different strategies. In one case, the material was air-cooled from the final rolling temperature and in the other case it underwent accelerated cooling from above the austenite to ferrite transformation. Both rolling...

Austenite grain size is an important parameter for controlling the mechanical properties of microalloyed steels during hot strip rolling. With the installation of a laser-ultrasonic (LUS) measurement gauge at SSAB’s hot strip mill in Borlänge, a sensitive, non-contact inline method is available that allows the grain structure to be measured immediately after the final finishing stand.
