on a theme: "Automatic control aftercooling of MCTP,isklyuchayuschee appearance of terschin"

The flow-chart of automatic control and management of aftercooling of MCTP, eliminating appearance of cracks is considered in the article. Influence, nascent termouprugikh tensions in neprerryvnolitoy to the round purveyance. On the preliminary stage by the mathematical model of consolidation and cooling of the continuously poured purveyance for the set size of purveyance of d and temperature-speed mode, the temperature field is certain.

On the second stage through the method known in resistance of materials, estimate the level of tensions, which corresponds the certain temperature field. We compare value in the section of purveyance with possible for this brand became, draw conclusion about possibility of appearance of cracks.

For control of accordance the calculation t surface of purveyance or at the end of sectors of ZVO set pyrometers and systems ACE TP. In the case of exceeding of possible tensions, correct cooling intensity, anew produce the calculation of the temperature field et cetera, until calculation tensions will not become less than possible. Thus for the regulators of charges of water on the sectors of ZVO the values of the proper intensity of cooling will be proposed. In the case of divergence correct a rate-of-flow until coincidences will not be attained.
