| چکیده | ||
| The tinplate quenching process at Mobarakeh Steel Company was analyzed for the first time using computational fluid dynamics to reduce the defect in the quench spot on the tinplate’s surface. The volume of a fluid model was used to simulate the process. The effect of nozzle angle equal to 15, 30, and 45 degrees, nozzle jet velocities of about 10 and 8 m/s, tinplated velocities of 244, 200, and 160 m/min, and cooling fluid temperature of 30, 40, and 55 °C on the tinplate temperature field was investigated. Results show that the tinplate temperature field is relatively uniform at a 45° nozzle angle. In addition, a more uniform temperature field was obtained by increasing the nozzle jet velocity from 8 m/s to 10 m/s and decreasing the tinplate velocity from 244 m/min down to 160 m/min. | ||

| چکیده [English] | ||
| فرآیند کوئنچ ورق قلع در شرکت فولاد مبارکه برای اولین بار با استفاده از شبیهسازی دینامیک سیالات محاسباتی برای کاهش نقص لکه کوئنچ در سطح ورق قلعاندود مورد تجزیه و تحلیل قرار گرفت. در این شبیهسازی از مدل حجم سیال استفاده شد. در این شبیهسازی، اثر زوایای مختلف نازل برابر با 15، 30 و 45 درجه، سرعتهای جت نازل در حدود m/s 10 و 8 ، سرعت های قلع کاری m/min 244، 200 و 160 و دمای سیال خنک کننده °C 30، 40 و 55 بر توزیع دمای ورق قلعاندود مورد بررسی قرار گرفت. نتایج نشان داد که توزیع دما در ورق قلعاندود در زاویه نازل 45 درجه نسبتاً یکنواخت است. علاوه بر این، با افزایش سرعت جت نازل از m/s 8 به m/s 10 و کاهش سرعت قلع اندود از m/min 244 به m/min 160، توزیع دمایی یکنواختتری به دست آمد. | ||
