Heating Technology

Continuous Hot-Dip Galvanizing lines are widely used for the production of coated steel sheets. Quality improvement measures are of great importance for this type of line. A significant proportion of production and quality losses when operating these types of lines occurs when production is transitioning from one strip gauge/thermal cycle to another. Utilizing induction heating technology, in combination with a sophisticated control system, can dramically decrease yield losses during transitions. Dynamic Transition and Production Planning Models have recently been developed for the simulation and control of the continuous hot-dip galvanizing line. The results of this work have been implemented in some galvanizing lines with production rate up to 350,000-ton annual capacity.

Laser Beam Heating

The efficiency of laser beam processes basically depends on the efficiency of the laser beam source and the efficiency of the irradiated material’s energy absorption. This absorptivity can be influenced by the surface condition. Besides coating or boundary layers, the surface topography is decisive. In this study, the effects of various time–temperature distributions on the absorptivity changes of steel sheets were investigated. For this purpose, three steels were chosen, namely, a stainless steel, a spring steel, and a hot work tool steel. Pre- and post-process characterizations of the absorptivity and surface topography were performed. Controlled heating with a laser beam was carried out using temperatures between 700 and 1200 °C and durations between 2 and 34 s. In order to compare the influences of these heating procedures on the absorptivity, a characteristic value, the temperature‑compensated time, was introduced. It is shown that the surface roughness was influenced by laser irradiation but inadequately describes the increase of absorptivity. The changes in absorptivity are attributed to oxidation, which had an influence on the topography in a sub‑micrometer range. Moreover, a saturation effect is observed for intense heatings. Furthermore, it is shown that the temperature‑compensated time is a suitable value to describe absorptivity changes caused by short‑term heating.
