3 V. Brief introduction ZJX-4X1600mm steel coil slitting line is used for slitting the carbon steel coils and hot dip galvanized coils to prepare for the next process. 1. Hydraulic entry coil car The car can move levelly and vertically, which is convenient for putting the steel coils into the de-coiler. It is driven vertically by φ200mm hydraulic cylinder with 4 guide pillars The level movement is driven by XWD cycloid motor Capacity: 15T Function: It is used to lift up and down, move forward and back to make it easy to load the coils on decoiler. Hydraulic controls lifting, motor drives moving. The car is controlled on the auxiliary control panel. Its moving speed is 6-7m/min. When the coils on decoiler, the car will return back to the start position. It can also carry back the unfinished coils from decoiler. 2. Hydraulic decoiler 15KW motor drives the decoiler running and the hydraulic drives it expand and shrink. Expanding model: oblique slider is driven by hydraulic oil cylinder. Max loading weight: 15T Mandrel: 45# steel processed by heat treatment and the diameter is φ219mm. It is home-made by our company. It is designed with the supporting stand which is driven by hydraulic to ensure the heavy weight of coils can be loading. It is designed with the press arm, the roller is made by rubber, this design is used to prevent the coils from loosing. 3. Straightener machine It is equipped with the press and pinch device at the entry which is driven by hydraulic. It is composed of 17 leveling rollers, 2 groups of supporting rollers,driving device and 2 pinch rollers and frame. Both sides of each rolling wheel is transmitted by needle pins all are the main force rollers. the total quantity of the rollers is 19, the diameter is 85 and the distance between the rollers is 90mm, with supporting rollers. All the rollers are plating leather to protect the stainless steel plate surface is not wear. The function of the supporting roller is to balance the leveling rollers force and reduce the friction to the rollers. The working rollers can be adjusted the gap electrically which is controlled by 2 hand wheel to ensure the leveling quality. Driving model: all the independent rollers and gear box are driven by 45Kw frequency control motor 4.Hydraulic cutting machine Adopt two columns structures, a press device, can cut the 4mmX1600 steel plates ; The up and down blades which are alloy material 9CrSi can adjust their gap; The machine is used for the steel shear and to make the plate easy to slitting machine.

5. Hydraulic lifting table The length of plates can range from 200-3000mm( which can be customized) The width can be ranged from 500 to 1600mm. 6.

Function : it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, the hydraulic cylinder lift the bridges to pass the steel sheets.

There is equipped with the photoelectricity devices to adjust the high or low speed to make sure the certain store quantity in pit. 7.

The width range is 500-1600mm. Function : it is used to prevent the sheet running to the wrong way.

4 5. Hydraulic lifting table The length of plates can range from mm( which can be customized) The width can be ranged from 500 to 1600mm. 6. Looper Ⅰ The pit is equipped with 2 groups of magic eyes to control the speed buffer between decoiler and slitter Magic eye is controlled by PLC. The pit size: 4500mmX2000mmX3000mm. Function : it is used to eliminate the different speed and make the plates which in wrong rail to back the right way. At first, the hydraulic cylinder lift the bridges to pass the steel sheets. when working, the bridges will lift down, the steel will be stored in the pit. There is equipped with the photoelectricity devices to adjust the high or low speed to make sure the certain store quantity in pit. 7. Side guide device It uses the vertical rollers of both sides to guide the plates into the slitting machine correctly. The guide rollers are adjusted by the rods on both sides. The width range is mm. Function : it is used to prevent the sheet running to the wrong way. On both sides of the plates width way, the stand rolling are fixed on their own position and can adjust the width manually to match the different width plates. There are 4 rollers (quenching HRC55-58) which divided into 2 rollers on each side. 8. Slitter (75KW DC ) Knife pivot specification: φ220x1600mm, material: 40Cr, heat treatment HB Host machine: This is composed of bottom-stand, fixed bracket, big slide, knife pivot(φ220mm, 2pcs), movable bracket, slide, the front and back adjustable device of bracket, knife pivot lifting and pressing down adjustment device. Power part: 75KW DC motor with JZQ 650 decelerator and universal coupling as well as gear distributing case, coupler, spindle, connectingcover, etc. Knife pivot press down device adopts the motor to lift up and down. It change the blades through moving out the bracket hydraulically and is very convenient and fast. 9. Scrap winder (5.5KW ) It consists of base, the shaft and plate for scrap material, friction wheel, supporting wheel chain, chain, decelerator and 5.5Kw motor,etc. 10. Looper Ⅱ The roller-table lift up and down by hydraulic. All the rollers on the table is chromed and between the rollers, it is designed with the Bakelite plate (Function: can prevent the sheets from scratching) At the exit part of the roller table, it is designed with the pre-dividing device. The size of the pit: 4000mm(L)x2000mm(W)x6000mm(D)

One hydraulic block device and two roller device. The press rollers as well as the two-roller device at the exit part are equipped with the air cylinder to control the lifting.

5 11. Tension stand It is composed of the base,pre-dividing device, tension press device and so on.
