流态床作为淬火介质,在常温下冷却速度介于油和空气之间而加热后,则可作为分级淬火和等温淬火的介质。在本文中,作者测定了影响特性曲线的各种参数,并叙述了一些应用的实例。前言不少文献介绍了在周期式罐状炉内以气流流化氧化铝微粒的流态床技术〔1、2〕这些文章一般都着重于流态床在单件或小批零件的加热应用,而本文的重点则是流态床在淬火冷却中的应用。热处理车间为获得淬火的最佳条件,提供一种适当的淬火介质是决定操作成败的关键。虽然现在常用的淬火
Fluidized bed as a quenching medium, at room temperature cooling rate between oil and air and heating, then as a classified quenching and isothermal quenching medium. In this paper, the author determines the various parameters that affect the characteristic curve and describes some examples of the application. Preface A number of references describe the fluidized bed technique of fluidizing alumina particles in a cyclic pot furnace [1, 2]. These articles generally focus on the heating application of a fluidized bed in a single or small lot of parts, The focus of this article is the application of fluidized bed quench cooling. Heat treatment workshop To obtain the best conditions for quenching, to provide a suitable quenching medium is the key to the success or failure of the operation. Although commonly used now quenching
