Our Advantages in Processing 熱間圧延鋼板
High Temperature Processing
Rolling steel at temperatures above 1700°F enables optimal malleability and formability, allowing for efficient shaping of large plates while maintaining consistent material properties throughout the entire piece. This high-temperature process reduces the energy required for deformation.
Efficient Single-Pass Formation
Hot rolling allows for significant size reduction in a single pass, making it possible to process large steel sections quickly and efficiently. This results in higher production rates and lower manufacturing costs compared to cold rolling processes.
Enhanced Material Strength
The hot rolling process refines the steel's grain structure during recrystallization, leading to improved mechanical properties and uniform strength distribution across the plate. This results in better structural integrity for heavy-duty applications.
