Description
Carbon steel wide and heavy plates are primarily composed of iron and carbon, with small amounts of other alloying elements possibly added depending on the required mechanical properties. These plates exhibit high strength, good toughness, and weldability, making them widely used in construction engineering, bridge building, shipbuilding, heavy machinery manufacturing, and large-scale infrastructure projects. Due to their thickness and dimensions, they are particularly suitable for structural components subjected to extreme pressure and heavy loads. The production process of wide and heavy plates includes billet preheating, roughing rolling, finishing rolling, cooling, and leveling, covering energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process. The dataset is formed by merging data from multiple sources.

Process Description
Heavy plate, also known as heavy-duty steel plate, is a large-sized steel product widely used in industrial applications. These plates typically have a thickness exceeding 20 millimeters and widths reaching several meters, making them suitable for manufacturing large structures and heavy machinery. Due to their dimensions and thickness, heavy plates offer excellent load-bearing capacity and stability, making them ideal materials for large-scale engineering projects and high-load applications. Carbon steel heavy plates are primarily composed of iron and carbon, and may include small amounts of other alloying elements depending on the desired mechanical properties.

Technology comment
The wide and heavy plate hot rolling process is a high-temperature processing method that transforms large-sized steel billets into wide and heavy plates. The raw steel billet is heated in a reheating furnace to an appropriate rolling temperature, then enters the roughing mill for initial rolling, during which the billet is pressed into a thicker semifinished product. After roughing, the billet enters the finishing mill stand where it is further rolled to achieve more precise thickness and width dimensions.
