16mm-8mm 200kw 8pass copper alloy /other alloy cold rolling machine
Technical process
First, check the device to see if it works normal (including that roll wheel stands must be fill with butter per shift, the sanitary conditions of frame and each guide and so on); after ensuring the normal condition of the equipment and safety operation, turn on the power supply; wait for the console touch screen to enter into the normal working screen, then open the oil pump. After the oil pump starts working, lubricating oil flows into the 2 high motive power frame. for a moment, through the transparent oil return pipe the lubricating oil can be seen to come out from the oil return hole of the motive power frame. At this time, open the rolling mill operation ( as well as forward and reverse); and then open the emulsion pump, wait for emulsion to flow out from each cooling point of the 2 high frame and roll the copper rod; the rolling speed can not be too fast at the beginning of rolling copper rod, but it can be speed up to normal produce when copper rod comes out from rolling mill and penetrates into take-up machine and coil basket. after penetration take up and looping basket ,can increase speed. turn into normal production. When finish, turn off the rolling mill(take-up machine),emulsion pump,oil pump,main power in order.
Main component
1. Rolling mill base 2. 2-roller motive power frame(including reducer, Inverter motor) 3. Pay-off frame 4. coiling take-up system 5. Lubrication system 6. Emulsion system 7. Electronic control system 8.straightening device
1main rolling mill
The main rolling mill is the important part of the continuous cold rolling mill . It includes base, frame, reducer, motor etc. Each frame is driven by an independent motor. All the basic rolling process is finished on the main rolling mill, and the number of the frames is different according to different rolling size.
guide system
each pass has entry and exit guide, odd frame of entry guide glides to lead in, and even frame rolls glides to lead in.
Coiling take-up machine
1 This machine consists of draught gear and take-up device, meets the characteristics of taking-up enclosure and requirements of constant taking-up speed. As the rotate speed must be steplessly adjusted within certain area, the AC inverter motor is adopted, and connected with rolling motor
electrical syste
The electrical system includes the power system and the controlling system.
feeding and straightening device
The feeding and straightening device is in front of the main rolling mill, and it is used to straighten the rods so that it can feed the rod easier.

Advantages
Rollers of each rolling stand are driven by separate inverter motor. When the shape of the pass and rotating speed of each pass stand roller are changed at the same time, each stand can operate asynchronously. Processing rollers can change the shape of the pass, and the gear ratio of each stand roller can be set on the touch screen. So on the premise of meeting the stand strength, 2-roller copper rod cold rolling mill can roll different dimensions of copper rod and also roll other materials.
