HRC CRC Steel Slitting Machine 25 Strips 120m/min PLC Control

ZJ-(0.4～4)×1600mm full automatic high precision high speed HRC CRC steel slitting machine

Introduction:
Because thickness of coil strips is in proportion to capacity of sheet slitting lines, the bigger thickness of master coils need the bigger models of coil slitting machines. Generally, we can classify slitting lines into three groups according to thickness difference, that is, thin sheet slitting line, middle thick coil slitting machine and thick coil metal coil slitter.

This thin sheet slitting line, also called metal coil slitter, is a kind of production line to break down master coils into smaller coils of a particular width. The thin sheet slitting line is made up of coil-loading car, single mandrel uncoiling, coil-end-feeding and shoveling, double roller pinching feeding, three-roller-leveling, end-cutting, strip-aligning, disk shearing, scrap reeling, hole accumulator, pre-separator, tensioning, recoiling ,coil down car, hydraulic control, and electric control.
Thin sheet slitting line is suitable for coil strip thickness (0.2~1) mm, (0.3-2) mm, (0.3-3) mm and (0.4-4)mm; while strip width is changeable: 600mm. 1000mm, 1250mm, 1600mm, 1800mm and so on.

Advantages & Characteristics of our Coil Slitting Machine:
1. Each production line (thin sheet slitting line) is designed and made strictly according to customer requirements. Not only this, our engineers carefully think over in customer's shoes, making sure whole metal coil slitter to be compact, smooth, solid and easy to operate.
2. Thin coils differ in coil weight, when max coil weight is small, usually single mandrel (cantilever) uncoiler is adopted for the metal coil slitter; when max coil weight is up to 25Tons, it is proper to use double mandrel uncoiler for the coil slitting machine.
3. Customer usually need narrow thin strips in high slitting precision. We attend much attention to centerline control, slitting accessories precision control, recoiling precision control, etc to make sure slitting precision at thin thickness.
4. When stainless steel, galvanized steel, colored steel coils are concerned, we take delicate measures such as rubber rollers, smooth transmit plates to protect sheet perfect surface not injured.
5. We have obvious advantage in hydraulic system design and production for this the thin sheet slitting line.
6. We always choose good suppliers of hydraulic parts, motors, speed reducers, electric parts. As well, we like to purchase those parts according to customer requirements for special metal coil slitter.
7. We strictly control each link of production process, from material purchase, to welding, machining, hardening & grinding, to assembly, to painting. Therefore, we can make sure good quality metal coil slitter.
8. We can supply same quality coil slitting machine at cheaper prices because we are good at production cost management.
9. AC motor or DC motor drive, customer can freely choose. Usually we adopt DC motor and Eurotherm 590 DC driver due to its advantages of stable running and big torque.
10. Safety operation is ensured by clear indications on thin sheet slitting line, safety devices such as emergency stop, etc.
