Steam is a byproduct of the steelmaking process. It is a critical form of energy used in many industrial and commercial applications, widely utilized for heating, electricity generation, and cleaning purposes. High-quality steam is essential to ensure process efficiency, equipment performance, and operational safety. The pressure, temperature, and purity of steam are key indicators determining its suitability and efficiency. This dataset was formed by merging data from multiple sources. The dataset describes a scrap steel input of approximately 0.42 kg/kg steel in electric arc furnace steelmaking.
