一、炉温分布和炉温变化 温度是影响热处理质量的重要因素。热处理工艺规程对温度有着严格的规定。但是,在实际工艺过程中,测温仪表所反映出来的温度与工件温度不可能完全一致。其原因,除了测温仪表有误差外,还有炉温差和炉温波动问题。所以,要保证热处理温度准确,除了测温仪表必须准确外,还应了解热处理电炉的炉温状况。 炉温状况是指电炉工作区域里(放置零件处)温度的分布,以及在保温时温度的变化状况。为了描述炉
First, the temperature distribution and temperature changes Temperature is an important factor affecting the quality of heat treatment. Heat treatment process rules have strict rules on temperature. However, in the actual process, the temperature reflected by the temperature measuring instrument can not be exactly the same as the temperature of the workpiece. The reason, in addition to errors in the thermometer, there are furnace temperature and temperature fluctuations. Therefore, to ensure that the heat treatment temperature is accurate, in addition to temperature measurement instruments must be accurate, but also should understand the heat treatment of furnace temperature. Furnace temperature condition refers to the electric furnace work area (placed parts) temperature distribution, and temperature changes in the insulation conditions. To describe the furnace
