Hot Rolling Machines
Rebar hot rolling machines are industrial equipment used in metalworking processes to deform and shape metal materials at high temperatures. These machines are crucial for producing various metal products such as sheets, plates, bars, and structural components. The hot rolling process involves passing the metal material through rollers while it is heated above its recrystallization temperature. Thus, it is easier for shaping and forming.
Ideal for high-volume production.
Produces rebar at higher speeds.
Suitable for large-scale manufacturing operations.
Cold Rolling Machines
Cold rebar rolling machines are used in metalworking processes to deform and shape metals at room temperature or slightly above. Unlike hot rolling, cold rolling machines operate at lower temperatures. Typically, it involves passing the metal material through rollers to reduce its thickness and improve its surface finish. Cold rolling is commonly used to produce sheets, strips, and foils with tighter tolerances and better surface quality.
