Furnace lining temperature measuring device
In the smelting process of medium frequency furnace, the lining material will gradually get thinner with the increase of furnace times. In the traditional furnace lining alarm system, stainless steel mesh is preset between the coil and the furnace lining, separated by mica paper or asbestos mesh and other materials. One end of the induction electrode is connected with the stainless steel protective mesh, and the other end is embedded in the refractory material at the bottom of the furnace. When the lining material is cracked and metal water penetrates, the current between the stainless steel mesh and the embedded electrode increases, and the alarm is triggered when the threshold is exceeded.

Introduction
In the smelting process of medium frequency furnace, the lining material will gradually get thinner with the increase of furnace times. In the traditional furnace lining alarm system, stainless steel mesh is preset between the coil and the furnace lining, separated by mica paper or asbestos mesh and other materials. One end of the induction electrode is connected with the stainless steel protective mesh, and the other end is embedded in the refractory material at the bottom of the furnace. When the lining material is cracked and metal water penetrates, the current between the stainless steel mesh and the embedded electrode increases, and the alarm is triggered when the threshold is exceeded.
Equipment Features
In the smelting process of medium frequency furnace, the lining material will gradually get thinner with the increase of furnace times. In the traditional furnace lining alarm system, stainless steel mesh is preset between the coil and the furnace lining, separated by mica paper or asbestos mesh and other materials. One end of the induction electrode is connected with the stainless steel protective mesh, and the other end is embedded in the refractory material at the bottom of the furnace. When the lining material is cracked and metal water penetrates, the current between the stainless steel mesh and the embedded electrode increases, and the alarm is triggered when the threshold is exceeded.
In the traditional alarm mode, there is a false alarm issue, the furnace lining is not completely dried or the induction electrode is short-circuited, which will cause false alarms. On the other hand, when the traditional alarm device alarms, most of the furnace lining has burned through, there is a safety risk. And every time the lining is re-sinteried, the alarm system needs to be reset, and the service life is determined by the life of the lining.
The optical fiber temperature measurement can monitor temperature change in real time. Real-time monitoring and recording of the whole furnace lining.
Overtemperature or abnormal temperature can be alarmed. The optical fiber is embedded in the coil cement. Under the allowable temperature, there is no furnace penetration or fuse.The optical fiber can be used for a long time.
