The core of carbon steel plate production lies in the four key stages: "raw material smelting → billet forming → rolling processing → finishing treatment". These stages transform raw materials such as iron ore and scrap steel into plates that meet specific requirements in terms of thickness, strength, and surface quality. The fundamental principle involves utilizing the hot and cold plasticity of steel, improving grain structure through pressure processing (rolling), and simultaneously controlling chemical composition and temperature to achieve optimal performance of the plates.
