Description
This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.
Activity Description
The production process of heavy plate includes stages such as billet preheating, rough rolling, finish rolling, cooling, and leveling, covering energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process.
Process Description
Medium and heavy plates are commonly used steel products, characterized by high strength, good toughness, and excellent weldability. There are various types of medium and heavy plates, including carbon steel plates, low-alloy steel plates, and stainless steel plates. They are typically manufactured through hot rolling, a process that ensures uniform thickness and a smooth surface. Medium and heavy plates can also undergo heat treatment and surface treatment according to different application requirements to enhance their corrosion resistance and wear resistance. Q235B carbon steel plate is a widely used low-carbon steel material, primarily composed of iron, carbon, and small amounts of elements such as silicon, manganese, phosphorus, and sulfur. Q235B carbon steel medium and heavy plates are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, and other fields.

Technology comment
The hot rolling process of heavy plate is a key procedure to transform the pre-processed steel billet into heavy plate. The raw steel billet is first heated in a reheating furnace to an appropriate rolling temperature, then fed into a roughing mill for initial rolling, where the billet is compressed into a thicker intermediate billet. After roughing, the slab enters a finishing mill stand for further rolling to achieve more precise thickness and width.
