Detail

In the production of China used pipe mills, it is necessary to know the production process regulations of each equipment in order to operate the Chinese used welded pipe mills according to the production process regulations.

 

China used pipe mills

 

The third step we first understand the shear butt welding process of China used pipe mills.

1. Start the hydraulic switch of the tensioning device to tension the inner coil of the strip steel.

2. Put down the pressure roller and remove the reel packaging tape with a clipping tool. At the same time, open the shovel head to the level, and then start the uncoiler motor to turn the head to the plane of the shovel head.

3. Rotate the uncoiler motor in the designated direction, so that the lead will continue to move forward on the plane of the shovel head until the leveling machine.

 

4. Turn on the leveler motor to drive the strip to move forward until the hydraulic shears, and at the same time turn off the decoiler motor.

5. Turn on the hydraulic shears, cut off the lead under the principle of no missing ruler and no waste (turn on the hydraulic shears), and then lift the hydraulic shears.

6. Restart the leveling pinch motor to feed the strip into the welding part.

7. After trimming the tail of the last coil, send it into the welding area together with the head of the new strip, adjust the welding parameters (including welding current, arc voltage, carbon dioxide flow), and weld the strip.

 

8. After gas shielded welding, the belt mouth shall be flat, free of slag, strong and firm, and the remaining height of the weld shall not exceed 1mm.

9. After welding the joint, lift up the pressing device, and then start the feed pinch roller motor to flush the connected steel belt into the horizontal spiral looper.

 

After learning the shearing butt welding process, you can carry out the actual operation principle of strip steel of China used pipe mills according to the shearing butt welding process.

The essence of adjusting the diagonals of the used square pipe mill is to adjust the square of the square tube. In theory, if the two diagonals of the square tube are equal, the square tube is square. But not necessarily for the rectangular tube in physical form.
