The apparatus for rapidly heating cold-rolled strip steel (10) comprises a heating zone, a soaking zone, and a cooling zone, and the heating zone is sequentially divided into a first heating section (1), a second heating section (2), a third heating section (3), and a fourth heating section (4) along a moving direction of the strip steel (10) to be heated, the first heating section (1) and the fourth heating section (4) being radiant heating sections, and the second heating section (2) and the third heating section (3) being inductive heating sections. The method for rapidly heating cold-rolled strip steel (10) uses the apparatus for rapidly heating cold-rolled strip steel (10) to heat the strip steel (10).

The present disclosure provides a method for controlling a power of an electromagnetic cooking appliance and an electromagnetic cooking appliance. The electromagnetic cooking appliance includes a first coil disk and a second coil disk. Each of the first coil disk and the second coil disk corresponds to an independent resonance circuit.

A sensor for measurements of thermophysical properties having an electrically conductive heating element provided in a circular shape on a base. The electrically conductive heating element is provided on the base in a pattern that is designed to better approximate a perfect circle so that the sensor better represents a circular solid disk source as described in the thermal equations used for measuring thermophysical properties, and thus requires a smaller empirical correction, improving the accuracy and certainty of measurements. The pattern of the electrically conductive heating element on the base is designed to optimize uniformity of heat distribution, thereby avoiding hot spots and, where hot spots are unable to be avoided, evenly distributes such hot spots.
