Method and apparatus incorporating an infrared sensor, in the form of a two-wavelength imaging pyrometer into a metallic spray form process for providing real-time measurement of the surface temperature distribution of a steel billet thereby formed. The steel billets may be advantageously used as tools in metal forming processes, injection molding, die casting tooling and other processes that require hard tooling, such as in the automotive industry. The steel billet is formed based on a goal of uniform surface temperature distribution thereby minimizing thermal stresses induced within the steel article thereby produced.
