[0001] The utility model relates to the technical field of iron and steel metallurgy, in particular to a device for judging the position of material flow. Background Art

[0002] In the iron and steel metallurgical process, the materials in the blast furnace ore trough and coke trough are transported to the blast furnace receiving trough through the main feeding belt after being weighed and screened, and then distributed into the furnace at the specified distribution angle through the feeding tank and the unloading tank. Generally speaking, ore and coke enter the furnace separately, but ore and coke share a main belt and a material tank. In order to improve operating efficiency and shorten material transportation time, it is required to quickly close the material tank valve after the ore is loaded into the material tank, and distribute the material into the furnace, and open the material tank valve before the coke arrives. Under normal circumstances, the feeding belt does not have the function of judging the position of the material flow, and it is easy to have material overflow due to inaccurate material position judgment.
