Abstract
Systems, methods, and apparatuses are provided herein that track an integrated deviation of a physical property of a material that corresponds to a variation or defect in the material. In one embodiment, molten steel begins to solidify and move past an instrumented region of a mold. Sensors in the mold can detect a deviation in temperature of the instrumented region of the mold that signifies a variation or defect in the surface of the slab material as it solidifies. The systems, methods, and apparatuses track the integrated temperature deviation to more clearly visualize defects that may otherwise not be detectable by simply observing the temperatures of the mold and slab material in real time.
