Strip steel temperature control method and device

The invention discloses a strip steel temperature control method, and relates to the technical field of metallurgy. The strip steel temperature control method comprises the steps that width-to-thickness ratio information of strip steel is obtained; whether the width-thickness ratio information of the strip steel is less than 4000 or not is judged; if the width-thickness ratio information of the strip steel is less than 4000, the strip steel temperature is set according to a Hot stop on control mode; and if the width-thickness ratio information of the strip steel is greater than or equal to 4000, the strip steel temperature is set according to a Hot stop off control mode. The technical problems that thin strip steel buckling is prevented due to the fact that an OA section adopts the mannerof cooling and temperature rising in sequence, the production preparation time is too long, and the heating rate of an overaging section cannot be adjusted according to the strip steel specification are solved.
