Process and apparatus for treating a continuous strip material

摘要

A rinsing process and apparatus for rinsing a continuous steel strip material includes a rinse tank positioned above a collection chamber for defining a rinsing station. The rinse tank includes spray nozzles for spraying rinse liquid onto the upper and lower surfaces of the advancing strip. Pinch rollers are provided at the receiving end and discharge end of the rinse tank. Movable seals are provided in the rinse tank to engage the pinch rollers to close the gap between the pinch rollers and the rinse tank to effectively close the liquid drain outlets of the rinse tank. A detecting device is provided to detect stoppage of the forward movement of the steel strip to actuate the seals and close the drain outlets of the rinse tank. A continuous supply of rinse liquid through the nozzles quickly raises the liquid level in the rinse tank to completely immerse the steel strip when the forward movement of the steel strip stops.
