Ferroalloys first introduced sensing devices

摘要

The present invention relates to cyclic binary alloy of iron In the formula degassing equipment device for degassing and inclusion reduction of molten steel in a secondary refining facility for teaching purity and value-added increase in the steelmaking process, in more detail the degassing treatment of molten steel as the foreign matter to the inlet of the input hopper jamming it relates to the influx of external air alloy of iron with incidental vacuum tank improved, to prevent a large quality accident in advance by preventing the alloy from being introduced into the iron the initial inlet sensing device.; The subject innovation is an alloy of iron storage hopper and the input hopper and in the degasification plant having a vacuum chamber and the like, by putting an alloy steel in a vacuum tank refining the molten steel Second, the alloy input line between the input hopper and the vacuum chamber is equipped with a sensor for detecting the flow of the iron, the sensor as is the power is cut off, if that is the rotary valve of the input hopper operation, when the rotary valve of the input hopper motion stopped, the power to be supplied is connected to the controller, wherein sensor provides a ferroalloy first inlet sensing device for transmitting an electrical signal to lock an on-off valve of the steam inlet pipe when the iron alloy flowing into the input line.
