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.

In the second step, we first understand the pre-loading process of China used pipe mills.

1. First check whether the appearance size of the strip coil meets the requirements of the production process card. If there is a problem, report to the leader of the class in time. When checking the quality of the strip coil, people should stand on the side of the strip coil to prevent the strip coil from falling down or unhooking. people.

2. After selecting the steel belt, instruct the crane operator to drop the hoisted steel belt vertically onto the loading trolley and adjust it. When hoisting the steel belt, use both gestures and spoken language. The hook must be hung firmly to prevent bumps and squeezing. Wait for the accident to happen.

3. After the strip coil is aligned, open the two cone heads evenly, leaving a certain size of steel coil between the two cone heads.

4. Start the loading trolley and move forward, and stop it when the center of the steel belt placed is in a straight line with the centers of the two cones.

5. Start the hydraulic lifting device so that the center of the steel coil and the center of the cone are approximately on the same horizontal line and on the midline of the rolling.

6. Evenly retract the two cone heads, so that the inner coil of the steel coil is close to the two cone head slopes.

7. After the cone head supports the steel coil, put down the hydraulic device, and at the same time exit the loading trolley, proceed to the lower coil and the material.

8. For the rolling mill without loading trolley, instruct the crane operator to safely put the strip steel into the tightening equipment of the decoiler.

After learning the pre-loading process, you can carry out the actual operation principle of strip steel of China used pipe mills according to the pre-loading process.
