The paper presents the comparison of optimization-regulation algorithms applied to secondary cooling zone in continuous steel casting where semi-product withdraws most its thermal energy. In production, requirements towards obtaining defect-free semi-products are increasing day-by-day and products, which would satisfy consumers a few decades ago, now far below minimum required quality. To fulfill quality demands occurrence defects as possible, some regulation process is needed. main concept...
Nowadays, people are increasingly interested in renewable energy sources and accumulation of for its efficient use. The use non-renewable resources is progressively decreasing due to their adverse changes climate conditions high production CO2 emissions. This work deals with the problem heat by means phase change a material using Stefan problem, which serves describe temperature distribution medium determine location interface between solid liquid phase. approach used desired properties...
A micro cogeneration unit based on a three-cylinder internal combustion engine, Skoda MPI 1.0 L compressed natural gas (CNG), with an output of 25 kW at 3000 RPM is proposed in this paper. It relatively simple which already adopted by the manufacturer to operate CNG. The engine life and design correspond original purpose use vehicle. detailed dynamic model was created GT-SUITE environment implemented into energy balance that includes its heat exchangers, generator, battery storage, water...
Steelmakers focus on producing high quality steel to minimize defects, as this strategy maximizes their productivity and profit. The paper describes how create a macro model of solidification continuously cast steel. described is fully 3D, non-stationary implemented in form suitable for GPU (Graphics Processing Unit). formation blank cracks follows the continuous casting from beginning problem production some grades. various criteria that can predict occurrence defects serve optimize...
Monitoring and evaluation of temperature distribution in continuous steel casting coupled with optimal intervals providing no defects can be used for the prediction crack formation cast strand.Crack locations further specified use mechanical stress-strain model.These are strongly dependent on zero ductility (ZDT) liquid impenetrable (LIT).To avoid excessive stress strain steel, parts strand where bending unbending take place should not ZDT LIT intervals.Thus, speed water flow rates through...
Production of overall CO2 emissions has exhibited a significant reduction in almost every industry the last decades. The steelmaking is still one most producers worldwide. processes and facilities used at steel plants, such as blast furnace electric arc furnace, generate large amount waste heat, which can be recovered meaningfully used. Another way to reduce number low-quality products which, due poor final quality, need scrapped. Steel product quality strongly dependent on continuous...
