750 Four Stands Tandem Cold Rolling Mill Line for Carbon Steel

750 Four Stands tandem cold rolling mill continuously reduce steel plate thickness at up to 280m/min from 2-4mm to 0.6-1.5mm.

The competition of the tandem mill is continuous one way from uncoiling to coiling without stop, so, automatic shear and welding machine, strip accumulator keep the continous process while changing coil, double recoilers are good option to improve production.

Layout process:
Hydraulic coil loading car, uncoiler, Five-roller straightening machine, Welding and cutting, horizontal spiral accumulator, input processing platform, four stands 4 roller rolling Mill, output processing platform, Re coiler, coil discharging car.

Parameters:

Tandem cold mill is high productivity, requiring:

• 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.

Two Coilers Option:

strip head comes to one coiler, belt wrapper holds the head and wraps it onto coiling mandrel, the steel strip start coiling up on the mandrel, speed up the coiling speed until maximum stable speed, when the coil tail welding seam comes close to the coiler, slow down the mill line, cut off the strip after tail welding seam.

We are metal coil sheet processing machine manufacturer and supplier, we dedicate to supply of good quality machines and provision of complete services.

We work in the coil processing machine field for over 20years, we design and make each machine customized. From machine parts materials selection, each part machining and treatment, whole machine assembly and surface painting, we carefully note each detail of whole production process to achieve good quality machine result.

Rich Experiences:

Our people witness the developing process of sheet processing machines and develop ourselves with market, thus able to supply customers good machines at competitive prices.

Efficient Responses:

Investment of metallurgical equipment is a system engineering, which requires comprehensive plan and successive execution. The efficient responses of the equipment suppliers are very important. We did well in this and cooperate with customers for long time.

Senses of Mission:

Nothing proceeds smoothly without any problem, the important is to face and solve the problem. We put problem solution in priority, never escape responsibilities. Supply of good machines creating profit for customers is our mission, the most profitable equipment is the best. Customer is the King, we must provide him the most suitable machine to return his trust.

After-sale Services:

We can send engineers to customer plant to do machine installation and commissioning; we provide hydraulic schematic drawing, electric principle diagrams, mechanic spare parts drawings, civil works drawing; We always listen and give consultation.
