150m/Min 2 Heads Tandem Cold Mill Black Hot Rolled Steel Coil Rolling Mill

2 Heads Tandem Cold Rolling Mill For Black HR Steel Coil

Plain carbon steel coil processing plant witness tandem cold rolling mill who continuously reduce steel plate thickness at hundreds of meters per minute, the tandem rolling mill can give multiple production.

The competition of the tandem mill is continuous rolling: one way from uncoiling to coiling and working without stop, so, automatic shear and welding machine, strip accumulator and double recoilers are on the rolling line.

Automatic shear & welding and spiral accumulator keep uncoiling and strip feeding continuous, double coilers are good way to keep continuous coiling. These characters of tandem rolling machine make automation and production go to huge scale.

For non pickled black Hot Rolled mild steel strip cold rolling, two heads tandem mill is popular, because it reduces thickness two passes continuously to reach the required 50 -60% gauge reduction. 

The rolling process includes uncoiler, shear welder, accumulator, two heads mill and recoiler. hydraulic system, electric control system, lubricating system are the indispensible conditions for the tandem cold mill smooth running.

Composition and Parameters:

Tandem cold mill is a high technology equipment, it requires:

• Huge power supply and consumption, high efficiency cold mill can save power and control rolling process cost.
• Emulsified water for rolling process cooling needs a big pool with filtering system to keep enough clean coolant.
• Electrc control cabinets and panels are high precision programming and reaction system to ensure high speed precision rolling.
• Tension cell synchronize the rolling speed and tension between two mills.
• Operator must be skilled to run the mill
• Thickness gauges are necessary to control sheet gauge.
• Thin oil lubricating system for gearboxes of mill and recoiler.
