Under cooling off, hot rolling laminar flow spouts quick calibration device in collector position

The utility model provides an under cooling off, hot rolling laminar flow spouts quick calibration device in collector position, belongs to black strip equipment technical field for mark fast spouting the collector position under the hot rolling layer cold. Its technical scheme is: it has 8 demarcation posts and the bottom plate is perpendicular is connected, and 8 two on demarcation posts are a set of, and post along the length direction series arrangement of bottom plate marks in four groups, and the distances between adjacent two sets of demarcation posts equal with adjacent two distances of spouting down between the collector that post horizontal dislocation installation on the bottom plate is markd by each group. The utility model discloses multiunit on the bottom plate is markd the post and has been injectd many positions of spouting the spray pipe on the collector down, guarantees each spray pipe that spouts the collector down and realizes that uniformly cross arranges to make belted steel obtain comparatively even tissue, the performance is even, can reduce effectively that number of times that appearance goes on reviewing is reviewed to getting of causing because of the performance is inhomogeneous and because of the performance does not conform to the quality objection number that produces, and simultaneously, uneven to produce the wooden dipper bent because of cooling off can also to avoid thick specification belted steel, improves belted steel plate -type quality.
