当前,我国轧钢加热炉的实际负载率较低,不仅带来了生产中的大量燃料浪费,也使炉子本身制造的一次投入以及投产后的维修管理费用增加,这在一定程度上与加热炉的设计能力以及辅助设施的出力设计得偏大有关。本文以合理确定轧钢加热炉设计能力为纽带,把轧钢工艺特点与火焰加热炉的热工特性以及炉子供热系统的电能利用特性有机地联系起来。给出了确定轧钢加热炉额定生产能力和最大生产能力的计算公式.提出了它们应分别作为炉体结构参数和炉子供热及供料系统的设计依据的结论。 相似文献

An i mportant reason of brick lining failure inblast furnace or other metallurgical furnaces is theunevenness of erosion[1],sothe gunning repair tech-nique has been developed in the last twenty yearsand used widely in blast furnace repairing, whichshows great advantages in ti me saving and cost re-duction[2 ,3]. Gunning repair technique can be classi-fied into wet gunning and dry gunning. Comparedwith dry gunning, wet gunning is characterized bysmall dust and rebound loss . But due to high wat… 相似文献

The role of refractory metals in high temperature applications is discussed in the context of structural intermetallic compounds. The use of refractory metals in the elemental form as well as its use as alloying additions is first discussed. A catalogue of refractory metal based structural intermetallics is then itemised. Two examples, a niobium-based structural intermetallic compound and the role of the refractory metal W in improving the thermal stability of TiAl-based intermetallics are then discussed. 相似文献

Bauxite is widely used for refractory production owing to its high alumina content and high melting point. Brazil is one of the world's biggest producers of bauxite for refractory applications, and Santa Catarina State can be highlighted as one of the biggest reservoirs of bauxite ore. In spite of this fact, its chemical and mineralogical characteristics are not well known as well as its high temperature properties. The studied ore was completely characterized [chemical (X-ray fluroscence), thermal (differential thermal analysis), mineralogical (X-ray diffraction), and microscopic (optical microscopy and scanning electron microscopy) analyses] and the results showed that the bauxite ore is suitable to be used as a raw material for refractory applications. 相似文献
