Description

Technical Field

[0001] The utility model relates to the technical field of furnace lining thickness measurement, in particular to a furnace lining thickness measurement device. Background Art

[0002] A furnace is a type of kiln. It can be divided into flame kilns and electric kilns according to the heat source. According to the heat source facing the blank, it can be divided into open flame kilns, muffle kilns and semi-muffle kilns. In addition, there are a variety of atmosphere kilns, electric porcelain kilns, etc. Due to the special properties and high temperatures of furnaces, the structure and thermal insulation of the furnaces are required to be very good. With the progress of industry in various countries around the world, furnaces are also developing towards large-scale, high-efficiency and long-life, gradually optimizing the structure of furnaces, improving the thermal insulation effect, and increasing the service life of furnace materials. At the same time, the refractory materials used for the lining of furnaces have also undergone major changes. New, high-efficiency refractory materials with long life and better lining protection and energy-saving coatings are gradually being used. The energy efficiency and life of furnaces are gradually improving, and medium-frequency furnaces are also a type of furnace.

[0003] At present, the medium frequency furnace on the market is the main equipment for melting and pouring molten iron in the factory. In actual use, the lining of the medium frequency furnace is often damaged in various ways during use, which has a great impact on the service life of the lining of the medium frequency furnace. When the lining is seriously damaged, it will cause leakage of liquid molten metal, and it may even explode when it flows out and encounters water. Therefore, after each furnace production is completed, the thickness of the lining needs to be measured. The upper, middle and lower parts of the furnace should be measured and the minimum value of the lining should be taken to ensure the integrity of the lining. However, due to the high temperature in the furnace, there are risks of scalding and falling when measuring the thickness of the lining. Most of them will use the furnace lining measuring instrument for measurement, but when the furnace lining measuring instrument is used for a long time, the scale on the furnace lining measuring instrument is easily corroded and damaged, which causes the furnace lining measuring instrument to be replaced as a whole, thereby increasing the use cost of the furnace lining measuring instrument.
