| 1 | CAB Furnace Atmosphere Visualisation Using Computational Fluid Dynamics显示文摘In today’s automotive industry almost all car and truck radiators, oil coolers and air conditioning heat exchangers are manufactured using Nocolok Controlled Atmosphere Brazing (CAB). One of the most critical elements of the brazing process is the atmosphere used to protect the flux. Oxygen content is the major variable affecting the performance of the nitrogen atmosphere. Furnace design and flow rate are the major factors affecting oxygen content. Optimisation of these atmosphere parameters has a significant impact on operating cost, and on the quality and consistency of the brazed product. Computational fluid dynamics provides a tool to visualise the atmosphere conditions within the furnace and to explore the effects of changing some of the variables. Modelling the atmosphere in a typical CAB furnace has shown the importance of the integrity of the curtains in maintaining the low oxygen levels required for successful Nocolok brazing. For a given set of curtains it has shown that the only effective way of decreasing oxygen levels is to increase atmosphere gas flow. | P F Stratton A P Richardson | 2004 | 材料热处理学报2004，25，05B： | 2 |

| 16 | Modelling of high speed gas quenching显示文摘Gas quenching has been used in vacuum furnaces for many years and its characteristics for bulk quenching of components are well known. More recently the use of gas quenching applied to single or small groups of components that were heated in either vacuum or conventional atmosphere furnaces has been proposed. Gas quenching may be seen as meeting the needs of modern 'batches-of-one' processing for 'just-in-time' manufacturing. It is clean, non-toxic and leaves no residues to be removed after processing. If this process is to be possible then heat extraction rates equivalent to those obtained from a medium quench oil must be achieved uniformly at the surface of real components. There are several strategies for meeting this aim: first, conventional high pressure quenching; second, moderate velocity quenching utilising a high heat transfer coefficient gas such as helium, and third, high velocity quenching utilising a gas with lower thermal efficiency. The implementation cost for the first strategy is high as is the miming cost of the second unless high cost gas recycling equipment is considered. In the third, overall costs can be minimised by using a low cost gas such as nitrogen without the need to recycle. It is this third strategy which is the subject of this paper. Computational Fluid Dynamics (CFD) was used to determine if indeed the process could achieve the required results and then to optimise the process parameters off-line. Implementation of a feasible process will then be carried out in the field. | P F Stratton, D Ho and Saxena 1.BOC Gases, European Development Centre, Rother Valley Way, Holbrook, Sheffield S20 3RP, UK. 2.The HOC Group Technical Centre, 100 Mountain Avenue, Murray Hill, New Jersey 07974-2064, USA | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 0 |
