The LD-converter is named after place names Linz and Donawitz in the Austria where the process was first used successfully. The LD converter is a refined version of the Bessemer converter where blowing of air is replaced with blowing oxygen. In this process, high-pressure oxygen is blown at the molten pig iron using a water-cooled lance.

Modeling and control of a four

In heavy plate rolling, the heated plates are plastically deformed by rolling mills. For this task, reversing four-high mill stands consisting of two work-rolls and two backup-rolls are often used. The plate is deformed between the two work-rolls in several rolling passes. The high rolling forces during the deformation cause the work-rolls to

Rolling Mills

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold
