[0002] In the prebaked anode production process, the last process is baking process.The main production equipment of this process is open loop baking furnace, and the open loop baking furnace uses natural gas as heat source, and the whole furnace body is built by refractory bricks and refractory mud.As shown in Figures Figure 10 、 Figure 12 and Figure 13 , the baking furnace 8 has several furnace chambers, and the adjacent furnace chambers are separated by furnace wall 81, and each furnace chamber has several material boxes 82, and the adjacent material boxes 82 are separated by flue wall 83, and the flue wall is vertically separated by partition wall 831, so that the flame and heat are transmitted in S shape in the flue wall 83.
[0003] During baking, the prebaked anode semi-finished product is placed in the material box of the baking furnace, and the heat generated by the combustion of natural gas in the flue wall is transmitted to the prebaked anode through the wall, and the baking is completed. In this process, the flame does not contact the prebaked anode, which is a type of heat exchange. Because the combustion of natural gas in the flue will produce high temperature, which will cause the deformation of the furnace wall and the flue wall of the baking furnace, and this deformation will cause the following problems:
[0004] First, the material box changes from a regular cuboid to an irregular shape, thereby affecting the loading and lifting of the prebaked anode.
[0005] Second, due to the deformation of the flue wall, cracks will occur in the wall, which will cause the flame to directly contact the prebaked anode, which will have a fatal impact on the quality of the anode.
[0006] Third, the deformation of the flue wall will cause great safety hazards to the entire baking furnace, and will easily cause gas leakage and wall collapse problems.
[0007] However, the current detection of the deformation of the flue wall of the baking furnace mainly relies on visual observation, which can only be observed directly and cannot make accurate judgments. UTILITY MODEL CONTENTS
