FIELD: process engineering.
SUBSTANCE: invention relates to control over state (S1, S2, S3) of rolled material (G, GX), in particular, rough strip. Said state is defined by indications of wedging or camber of rolled material (G, GX). For this, rolled material (G, GX) is changed from initial state (S1) by rolling at roughing stand 1 and introducing strain (σ) to said material by means of extra machining means 7, 8, into intermediate state (S2). Note here that rolled material (G) is changed from intermediate state (S2) by means of, at least, one machining unit (A1, A2, A3,…AN) into final state (S3). Note here that, at this stage, defined is if rolled material (G, GX) is to be fed into said machining unit (A1, A2, A3,…, AN) intermediate state of which requires wedging or camber other than zero to ensure preset final state (S3'). This condition dully allowed for, duly intermediate state (S2) is set by control and/or adjustment of stand 1 and/or machining means 7, 8.
EFFECT: higher reliability and efficiency.
