The hot rolling machine, as the core equipment in metal processing, has the following applications and characteristics:
1. Main application fields
Steel industry
Used for producing steel plates, steel strips, and profiles, widely applied in construction (steel structures, bridges), automotive manufacturing (chassis, body parts), shipbuilding and mechanical manufacturing (gears, shaft parts), etc.
Non-ferrous metal processing
Designed specifically for copper, aluminum, and aluminum alloys, suitable for the rolling of high-strength and difficult-to-deform metals, commonly found in precision fields such as aerospace and electronic components.
Special material production
Including weather-resistant steel (container, building structure), stainless steel (chemical equipment, medical devices), and high-pressure vessel steel, etc.
2. Core features
Process advantages
Efficient and energy-saving: Rolling above the metal's recrystallization temperature, reducing deformation resistance and energy consumption.
Large-scale production: Using large ingots and large reduction ratios for rolling, with fast rhythm and high output.
Material performance improvement
Transforming the as-cast structure into the processed structure, significantly improving the material's plasticity.
The rolled plates have anisotropy, with significant differences in properties along the longitudinal and transverse directions.
Equipment characteristics
Equipment such as two-roll hot rolling machines support dual-mode processing (hot rolling/cold rolling interchangeable), equipped with hydraulic and electrical control systems to achieve precise parameter adjustment.
Single-frame double-coil hot rolling machines have both rough and fine rolling functions, requiring comprehensive consideration of the selection of working rolls and rolling thickness.
3. Market trends With the growth in demand for infrastructure and the automotive industry, the application of hot-rolled plates has continued to expand in areas such as building structural components and automotive parts. Its high cost-effectiveness and forming advantages have driven the development of the market.
