Title: The Innovative Contributions of Jean C Werquin
Introduction
Jean C Werquin, an esteemed inventor based in Ronchin, France, has made notable advancements in the field of metallurgy, particularly related to rolling mill technology. With a total of two patents to his name, his inventions aim to enhance the performance and durability of rolling machines used in industrial applications.
Latest Patents
One of Werquin's latest inventions is titled "Rolling mill roll for a hot train of rolls." This invention seeks to address the challenges encountered during the process of hot rolling by improving the performance of rolls in roughing and finishing stands of a hot strip mill. Specifically, the invention aims to mitigate the banding phenomenon, which involves the incrustation of hard oxides or scales formed at conventional rolling temperatures. The roll is engineered from chrome steel in the working region, with a chromium-to-carbon content ratio maintained between 7 and 12%, and an equivalent carbon content ranging from 1.5% to 1.7%.
In addition to this, his second patent, "Cast cold rolling roll," involves a composite bimetallic roll for cold rolling obtained through casting. This innovative design features a heart metal made from nodular or lamellar cast iron, combined with a case metal characterized by a chromium content of 8% to 16% and a carbon content of 0.65% to 0.95%. The chromium-to-carbon ratio in this instance is maintained between 11 and 16, ensuring a martensitic structure with less than 10% residual austenite in the case metal.
