What is belt slip? Why? Measures?

When the blank is thick and soft, and the reduction is large, it is easy to slip and scratch the strip steel, which is called belt slip.

Second, the belt slip reason:

1, broken belt. After the belt is broken, it is easy to slip and stick due to the change of tension.

2. Rolling steel strip material. Strip steel with teeth in the middle or back is usually soft. Under the same pressure, the thinning amount will increase and the biting angle will increase. The friction between the steel strip and the roller increases, which makes the deformation unstable.

3. The tension is too great, and it is not adjusted according to the material of the strip. Excessive tension will not only cause belt breakage, but also reduce rolling pressure. When the reduction is the same, the reduction will inevitably increase.

4. Poor lubrication. Poor lubrication during rolling will increase the friction between the roller and the strip and increase the biting angle.

And the instability of the strip is improved.

Third, the solution:

1. If there is too much water in the running materials or the site environment is wet, the construction personnel should try their best to ensure that the running site is as dry as possible, and drain and dehumidify the construction environment to increase the dryness of the belt running environment.

2. If the friction between the belt and the drum is not enough or the belt load is too large, the construction personnel should try to increase the friction between the belt and the drum to enhance the bearing strength of the drum and ensure the high-strength operation of materials.

Preventive measures for belt slippage:

1. After the belt is installed and operated for a period of time, the belt will become loose, so the belt tensioner should be adjusted to a suitable position.

2. Always adjust the position of the scraper to keep the gap between the scraper and the belt between1-1.5mm. ..

3. Observe the dryness and wetness of the soil discharged by the screw machine and adjust the water flow.

4. After each push, all the soil on the belt conveyor should be discharged into the soil box, and the belt conveyor should be started with no load.
