Continuous Cold Rolling Mill
Compared with single stand rolling mill, continuous cold rolling mill(Tandem cold rolling mill) is several mills laid out in the line. We can provide two-stand cold rolling mill,three-stand cold rolling mill,four-stand cold rolling mill and five-stand cold rolling mill,which equipped with hydraulic screw-down AGC and automatic thickness gauge,and applied with the technology of endless rolling and automatic welding.
Feature:
High efficiency:The strips pass the mills continuously by one time, it no need to stop unless when you change work roll. But the reversible CRM need to stop when change new coil.
High yield: Continuous cold rolling mill ensures the strips are rolled continuously from head to tail including welding line between coils under fully automatic thickness control system. But a dead zone exists during head or tail rolling in reversing mills which cause strip waste and lower yield compared with tandem mills rolling process.
Low power cost:Continuous tandem rolling mill does not require coiling devices which are driven by high power motors and thus electricity is saved.
Process of continuous CRM:
uncoiler → welding platform → looper → continuous rolling mill sets → frame → hydraulic shear → welder Thickness gauge → stand No.2 → stand No.3 → stnad No.4 → stnad No.5→ thickness gauge →hydraulic shear →coiler
