Background
The hot rolling production is a production method for carrying out pressure processing on metal at the high temperature of 850-1250 ℃, but in the stage of a hot output roller way, the amount of cooling water has a strong correlation with the speed of temperature drop of strip steel and the strength of the strip steel. The water requirement of the hot output roller table is mainly related to the thickness of the strip steel and the width of the strip steel.
At present, two methods of shielding the edge part by a laminar flow cooling header and using an internal piston type water plugging nozzle are generally adopted for the water spraying amount of the header of the thermal output roller way. The former can change the width of water spraying, but the driving pair of the driving device is simple and crude, is easy to be blocked and is difficult to operate; the latter can adjust the water quantity, but because the fault point is more, the field is generally not used, and also can not adjust the cooling width.
