This production line is a heating equipment combining technologies of thermal engineering, mechanism, auto-control, hydraumatic, photoelectricity and thermometry. It forms an indispensable part of the aluminum extrusion lines together with the extrusion press. It consumes oil, coal or gas (natural gas, liquefied gas, city gas and generator gas) as the heating fuel. Hot shearing, hot saw and stripping machine can be chosen as the supporting facility for this production.
