一种钢球法回收高炉渣余热的接渣槽
By designing a slag receiving trough structure with hydraulic rods and movable top rods, the problem of slag ball mixture sticking to the slag receiving trough and being difficult to pour out during the steel ball method for recovering waste heat from blast furnace slag was solved. This enabled the smooth pouring out of slag balls and convenient use of the slag receiving trough, thereby improving the efficiency of waste heat recovery.

AI Technical Summary
When steel balls are mixed with molten blast furnace slag, the slag receiving troughs stick together, making it difficult to pour out. This sticking together makes it difficult to pour out the slag, affecting subsequent crushing and waste heat recovery.
A slag receiving trough for recovering waste heat from blast furnace slag using the steel ball method is designed. By setting up hydraulic rods and movable top rods, the solidified slag ball mixture is prevented from sticking to the slag receiving trough. Electric push rods and supports are used for positioning, and a stepper motor is used to control the tilting to ensure that the slag ball mixture is poured out smoothly.
This allows for the smooth discharge of the slag-ball mixture, improving the ease of use and efficiency of the slag receiving trough, preventing slag receiving trough shaking, and ensuring the smooth progress of subsequent crushing and waste heat recovery.
