At first, metallic plate P is directed under the state of guide roller 14 from the upstream side of the smoothing roll unit 20 of roll leveller 100, towards smoothing roll unit 20 transferring metal plate P, and insert it into 8 of upper straightening roll 6 and lower smoothing rolls.For example, in the situation that the throughput direction of metallic plate P is the A direction, from the left side of Fig. 1 to smoothing roll unit 20 transferring metal plate P, be the cylinder body of depressing into side and depress cylinder body 4a.
At this moment, according to the thickness of metallic plate P etc., set the needed amount of being pressed into (drafts) of depressing cylinder body 4a and 4b of aligning (aligning) of metallic plate P at control device 30, carry out the aligning of metallic plate P with the amount of being pressed into after this setting (drafts).
But, the amount of being pressed into (drafts) after the setting of depressing cylinder body (in the situation that the throughput direction of metallic plate P is the A direction for depressing cylinder body 4a) that enters side surpasses the engaging-in limit amount of being pressed into, and produces the engaging-in defective that metallic plate P does not have 8 of engaging-in upper straightening roll 6 and lower smoothing rolls.
Therefore, under these circumstances, carry out engaging-in Correction and Control based on the engaging-in correction card of Fig. 4, thereby prevent so engaging-in defective.In addition, in fact the engaging-in correction card of Fig. 4 charges to concrete numerical value.
Particularly, before 8 of the upper straightening roll 6 of the engaging-in smoothing roll of metallic plate P unit 20 and lower smoothing rolls, utilize the process controller 31 of control device 30, the engaging-in limit amount of the being pressed into δ L that divides to the setting amount of the being pressed into δ e1 that depresses cylinder body that enters side that sets according to conditions such as thicknesss of slab, with the thickness of slab corresponding to metallic plate P in the engaging-in correction card of Fig. 4 compares.And, in the situation that the setting amount of being pressed into δ e1 surpasses the engaging-in limit amount of being pressed into δ L, go to engaging-in modification model.
