EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Natural gas burners are prevailing tools for a wide range of metallurgical operations. The field of usage is extensive and includes, i.e., melting of scrap in EAF, heating of slabs in pre-heating furnaces or post combustion in off-gas treatment plants. Since the invention of the Bunsen burner in 1857 the design of natural gas burners have changed substantially. Modern day burner designs like...

The Surface Roughness Meter (SRM), developed by CRM and commercialised by Amepa, has been enhanced by additional waviness measurement. SRM, deployed nowadays at more than 40 installations around the world, is used in several industrial lines and interest is more and more increasing from automotive and high quality surface products manufacturers and users. These applications, including...

3rd generation advanced high-strength steel (AHSS) grades are complex materials with special chemical compositions and multiphase microstructures. The annealing and galvanizing process of these grades is different and places new demands on the plant technology. One of them is the prevention of surface faults. Bare spots can occur due to a higher content of alloying elements like silicon or...

CRM has developed a very precise method to measure the shape and vibrations just above the wipers on galvanising lines. Based on mirror-principle, this method allows to reach 0.1mm precision in position and 50Hz in vibrations and is adjustable to a wide range of wipers. The measurements done can be used to control the shape and vibrations of strip leading so to a better coating homogeneity and...
