Основные области применения горячекатаной и холоднокатаной стали
The main uses of hot rolled steel Structural steel: Mainly used in the production of steel structures, bridges, ships, and vehicles. Hot-rolled steel is widely used in large-scale building structures due to its good machinability and weldability. Weathering steel: Hot-rolled steel with special elements (such as P, Cu, C, etc.) has good corrosion resistance and […]
The Difference Between Hot Rolled Steel and Cold Rolled Steel
Formation Hot-rolled steel: slabs are used as raw materials, and after heating, they are made into strip steel by rough rolling units and finishing rolling units. Cold-rolled steel: hot-rolled steel coils are used as raw materials, and after pickling to remove the oxide scale, cold rolling is carried out, and the finished product is hard […]
Advantages and disadvantages of hot rolling and cold rolling
Hot rolling and cold rolling are the two main methods of steel processing, each with its own unique advantages and disadvantages. Advantages of hot rolling Fast forming speed and high output: The hot rolling process adopts a continuous and automated production method, which can quickly complete the forming of steel and has high production efficiency.
