Title: Innovations of Hans U Franzen in Continuous Casting Technology

Introduction

Hans U Franzen is a notable inventor based in Duisburg, Germany. He has made significant contributions to the field of continuous casting technology, particularly in the production of thin slab ingots. With a total of 3 patents to his name, Franzen's work has advanced the efficiency and quality of steel casting processes.

Latest Patents

One of his latest patents is a "Method for continuous casting of thin slab ingots." This innovative method allows for the continuous casting of thin slab ingots with reduced thickness, utilizing a mold that is open at the bottom. The process involves roller pairs arranged along the withdrawal path, with some rollers being driven and hydraulically adjustable. This design enables precise control over the speed of the driven rollers and the pressure force of the adjustable roller pairs acting against the ingot. The invention also includes feedback control mechanisms to maintain a dynamic solidification point during the casting process.

Another significant patent is the "Method of continuous casting," which introduces a movable immersion nozzle for introducing melt into the mold. This method controls the start of the casting process based on the height of the steel surface in the mold. It also involves measuring the bath level as it ascends and adjusting the immersion nozzle's position accordingly. The desired operating position of the nozzle is determined by various factors, including the temperature of the steel melt and the quality of the steel.
