Use of mathematical models to obtain desired structures in as-rolled carbon-steel wire rod
The demand for carbon steel wire rods with guaranteed quality makes it increasingly important to identify and control the hot rolling and controlled cooling conditions in order to obtain the strength, ductility and drawability characteristics that allow a direct use of the product without further heat treatments. This goal can be reached functionally by developing and using mathematical models that predict the evolution of the steel microstructure during the manufacturing cycle and give a reliable valuation of the final mechanical properties. A set of mutually integrated mathematical models able to give a quantitative description of the thermal and microstructure evolution during each phase of the wire rod manufacturing process (reheating, hot-rolling, controlled cooling) was therefore developed and tested on an industrial scale at ILVA wire mill in Piombino works. These models can be applied either for programming the development of optimum wire rod structures and mechanical properties or for carrying out a sensitivity analysis according to the contribution of the different process parameters.
