本文介绍的是一种用于铜合金管材热处理的新型辊底室式炉。由于要在这种炉子中处理管料的材质及尺寸的多样性,因而有必要开发出这样一种炉型,以便即使在工作温度范围很宽及相应的冷却梯度很大的情况下,仍能保证热处理过程的合理性。为此,我们设计了一种强对流冷却室,同时又是出料真空室。室内既可以用普通的 DX 保护气工作,又可以用纯氢工作,为此所必要的安全保障功能是由过程控制装置中的信息系统来实现的.这里还将简单介绍这种炉子的工作过程.
This article describes a new type of roller hearth furnace for heat treatment of copper alloy pipes. Due to the variety of materials and sizes to be managed in such furnaces, it is necessary to develop such a furnace type that, even with a wide operating temperature range and a correspondingly large cooling gradient Ensure the heat treatment process is reasonable. For this reason, we designed a strong convection cooling chamber, while discharging the vacuum chamber. Indoors, you can work with ordinary DX gas, but also can work with pure hydrogen, for which the necessary security features are achieved by the information system of the process control device. Here will also be a brief description of the work process of this furnace .
