一、小波幅的用途:小波幅的应用,可以消除热处理加热炉在保温期间炉温波动较大的现象。这种现象反映在记录纸上的曲线近于正弦曲线。其波动的大小(波峰和波谷的大小),主要决定于测温元件(热电偶)的热惰性,而这种惰性与热电偶保护管的厚度及热电偶的测温位置(与热源相对位置)有关。就是保护管越厚,热电偶距热源越远,其惰性越大,记录曲线的波动越大,炉內的温度波动也
First, the use of small amplitude: the application of small amplitude, heat treatment furnace can eliminate the furnace temperature fluctuations during the larger phenomenon. This phenomenon is reflected on the recording paper curve near the sinusoidal curve. The size of the ripple (crests and troughs) depends mainly on the thermal inertia of the temperature sensing element (thermocouple), and the thickness of the inerting and thermocouple protection tube and the temperature measurement position of the thermocouple (relative to the heat source) related. Is the thicker the protection tube, the farther the thermocouple is from the heat source, the greater its inertia, the greater the fluctuation of the recording curve, the temperature fluctuation in the furnace
