Abstract
Изобретение относится к способу и устройству для управления металлургической печью (4). Способ включает стадию подачи и стадию регулирования температуры слоя (1) расплавленного металла и слоя (2) шлака в пространстве (3) металлургической печи (4). Стадия регулирования температуры включает первую стадию измерения температуры, на которой измеряют температуру шлака (Т), вторую стадию измерения температуры, на которой измеряют температуру ликвидуса шлака (Т) и стадию расчета температуры перегрева (Т) посредством вычисления разности температур между температурой шлака (Т) и температурой ликвидуса шлака (Т). В случае выхода рассчитанной температуры перегрева (Т) за пределы заданного интервала (Т) температуры перегрева способ включает стадию регулирования фактической температуры перегрева. Изобретение также относится к компьютерным программным продуктам.
