CNC Slitting Line
The slitting line for steel coils is a crucial production line that employs a meticulous array of rolls and cutters to divide large steel coils into smaller, more manageable coils of various widths and thicknesses. This line typically encompasses an uncoiler, entry guide rolls, a slitting head, scrap winder, tension reel, and a recoiler, each component playing a pivotal role in the precision cutting process. The versatility of the slitting line allows for the production of steel coils tailored to specific applications, ranging from automotive components to construction materials and beyond.

iTOKO’s slitting machines are crafted with a focus on automation, top-tier quality, energy efficiency, productivity, and operational stability. The design and manufacture of these machines are optimized to ensure maximum performance and long-term reliability. The slitting line can be categorized based on winding type, driving mechanism, and winding tension control, providing a comprehensive range of solutions to meet the unique requirements of various industries.

Cut to Length Line

Cut-to-length (CTL) lines are commonly used for processing steel coils. These lines use a uncoiler to unwind the coil, a feeder to control the rate of the coil's unwinding, and a leveler to reduce the coil's shape imperfections before the line shears it into the desired lengths. The line can also include other equipment such as a straightener, brush cleaner or degreaser, punching unit, or treatment line.

iTOKO's Cut-to-Length line is crafted with a focus on automation, high-quality materials, energy efficiency, productivity, and operational stability. Our commitment to continuous innovation ensures that our CTL lines are equipped with the latest technological advancements, delivering consistent, reliable performance.

Cold Rolling Mill
TOKO design purpose for "Four-high two-stand cold rolling mill" is to achieve high-precision and efficient rolling of metal sheets. It utilizes four rollers in each stand to provide stability and control during the rolling process, ensuring accurate thickness and surface quality of the rolled product. The two-stand configuration allows for multiple passes and progressive reduction in thickness, enhancing the overall rolling efficiency. This design is tailored for industrial production, aiming to meet the demands for high-quality metal sheets in various applications.

Automatic Gauge Control"AGC", is a system used in cold rolling mills to continuously monitor and adjust the thickness of the metal being rolled. This system employs sensors and feedback mechanisms to measure the thickness of the metal in real-time and make adjustments to the rolling process to maintain a consistent thickness. AGC systems can improve product quality, reduce waste, and increase production efficiency by ensuring accurate thickness control. view more details at Cold Rolling Mill

Tube & Pipe Mill
A tube/pipe making mill is a facility dedicated to the production of tubular products, such as pipes and tubes. These products are used in a wide range of applications, including but not limited to plumbing, construction, oil and gas drilling, and transportation.

Tube/pipe making mills are equipped with advanced technologies and machines to ensure efficient production, high product quality, and consistency. Quality control measures are also strictly implemented to meet industry standards and customer requirements. The resulting tubular products are then inspected, tested, and packed for shipment to various industries and applications.
 
General process is stated same as below:

1. Decoiling Unrolling the winded skelp.
2. Butt welding Connecting the both ends of skelp for the continuous production.
3. Accumulator Stacking the connected skelp to decrease the material preparation time.
4. Forming Passing skelp through the roll forming tool.
5. Welding Welding process by electric resistance.
6. Cooling Air and water cooling to uniformalize the heated organization after high frequency heat treatment process.
7. Sizing To accurate the out diameter of pipe.
8. Cut-Off Cutting to ordered dimension.
9. Straightening Passing through the correction gap for the straightness.
10. End facing Chamfering & beveling the cut side according customer’s order.
11. Hydrostatic testing Checking the water leak and crack.
12. Packing Packing by ordered.
iTOKO is committed to adhering to mill-stand's principles when manufacturing not only the main parts, but also the front and rear components. We strive to achieve the highest quality standard by maintaining consistent process standards and precision.
