Process Description
Wide and heavy plates, also known as heavy-section steel plates, are large-sized steel products widely used in industrial applications. These plates typically have a thickness exceeding 20 mm and can span several meters in width, making them suitable for manufacturing large structures and heavy machinery. Due to their dimensions and thickness, wide and heavy plates offer excellent load-bearing capacity and stability, making them ideal materials for large-scale engineering projects and high-load applications. Q235B wide and heavy plate is a carbon structural steel plate belonging to the Q235 series defined in the Chinese standard GB/T 700. Q235B indicates that the material has good plasticity, toughness, and weldability, as well as certain strength, and is widely used in fields such as construction engineering, bridges, shipbuilding, vehicle manufacturing, high-pressure vessels, and heavy machinery structures.

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.
