AUTOMATIC CONTROL OF TEMPERATURE AND POWER CONDITIONS DURING ROUGH GRINDING OF SLABS

The production of high-quality rolled products (slabs), the formation its surface phase-structural composition, texture, stress state during rough grinding depends on temperature in area contact between wheel and slab. During processing, due to geometric errors surface, as well local changes hardness, periodic fluctuations instantaneous depth cut occur, which can be determined indirectly by controlling one technological parameters, for example, power spent grinding, with subsequent recalculation it online values. is described a control object form an aperiodic link. Computer simulation has confirmed efficiency system maintaining specified slab under various operating conditions that simulate situations real production.
