摘要
本研究探討連續爐之熱流場,分析不同操作條件下對爐溫、熱流場分布及NOx排放的影響,並 探討工件隨著板車從爐內低溫處送至高溫處的過程中,在爐內不同區段的溫度變化。研究結果顯示 爐內無工件的部分,爐內溫度要達成至少要有300公分持溫段(1,050oC)的需求是一大挑戰。在工件 的加熱模擬中,發現在預熱、加溫段工件受屏蔽影響其溫度分布落差大,但加熱完的工件則不受屏 蔽的影響,所有工件溫度差距10oC內,但要符合工件表面完全持溫(1,040oC)的需求仍有努力空間。

This study explores the thermal flow field of continuous furnace, and analyzes the effects of furnace temperature, heat flow field distribution and NOx emissions under different operating conditions. This research also discusses the temperature changes of the workpieces in different sections of the furnace as the workpieces are sent from the low temperature to the high temperature. The results of the study show that it is a huge challenge to reach 1,050oC in temperature soaking zone at least 300 cm when there is no any workpiece in the furnace. In the workpiece-heating simulation, it is found that the temperature distribution of the workpieces is affected significantly by shielding during the preheating and heating stages. However, the heated workpieces are not affected by the shielding. The temperature difference of all workpieces is within 10oC, but there is little improvement for work to meet the requirements which the workpieces’ surface is fully maintain temperature (1,040oC).
