From liquid steel to the finished component, our measuring systems always accompany you through your processes. Benefit from great savings potentials by improving your quality, increasing your production output, and selecting your process parameters more closely in order to conserve energy and valuable resources.
Slag detection in the liquid stage Our slag detection at the electric arc furnace, converter (TSD), and the ladles (ESD) reduces the slag which could be brought into the product through all process steps, and at the same time, increases the output by reducing the amount of residual steel. AMEPA Slag Detection Systems, therefore, make a significant contribution to the economic efficiency of the entire process. Steel has been considered a high-tech product for a long time, and the demands for precise material characteristics and properties, and repeatable quality continue to increase. Precise slag detection enables you to reduce slag discharge, increase your quality, and fulfill your customers’ requirements. Surface area parameters for sheet metal Regardless of whether this refers to aluminum or steel, surface area characteristics are becoming more and more process-relevant, and customer requirements are more and more product-specific. With our measuring systems for roughness (SRM), waviness (WMS), and oil layers (OFM and OFIS), you always have your quality in view at all times. Even the smallest imperfections on the metal strip can mean a large scrap level for the customer. In car bodywork and chassis construction, with today’s design requirements and modern thin-layer paints, the smallest defects on sheet metal are immediately visible on the end product. You can detect and eliminate deviations in the production process or during inspection and deliver the highest quality to the customer.
The ESD Electromagnetic Slag Detection on the outlet of the ladle generates an alarm as soon as slag flows through it. Automatic closing of the slide-gate enables the slag flowing through to be reduced by up to 90 %. The steel output is increased, and its quality is enhanced. Longer sequences and fewer interruptions contribute to high efficiency.
AMEPA’s optical slag detection system utilizes a thermographic technology in order to detect the flow of slag when transferring from an oxygen steel converter or electric furnace to the ladle. The measuring system, which comprises an infra-red camera, an evaluation computer, and a display device, supports the user to reliably end each tapping process at the optimum time. This minimizes slag transfer onto the next process step and prevents time-consuming slag removal operations.
The surface roughness is a relevant parameter for the process control of texturing sheet material and is critical for additional processing and product shaping. Typical applications for this measurement are located in rolling mills for the continuous inspection of coils and in press shops for controlled inspection of blanks for products in the automotive industry.
Punctual detection of ripple values outside specified tolerances enables optimal process control, short response times, and increases dynamics. Wsa measurements are possible on strip speeds up to 180 m/minute with a measuring range of 0.1 to 1 µm and a resolution of 0.001 µm.
OFM Oil Film Measurement can be utilized in steel, aluminum, and automotive production processes. Users in the rolling mill and the press shop can utilize the measurement results for optimizing their processes. Timely detection of oiling errors with immediate online warning can reduce the number of customer complaints and faulty production quantities.
Specifically designed for industrial use, measurement with the Portable Oil Film Measuring Device is possible directly at the production location. The OFIS enables the reliable detection of dry streaks and incorrect oiling, with an immediate warning in the event of deviations in oiling, and provides long-term archiving of quality data for TQM.
