Beijing TET will
supply precious multi-roll leveler (four high/ six high) which
will be used in strip finishing process after cold rolling in
order to eliminate all kinds of bugs in strip surface and tension
differences between lengthwise and transverse to promote the
property of deep-drawing.

Special Mill Features:
The high process
precision and flatness
Six high multi-roll
leveler will be able to supply better flatness than four high.
