Why is the weathering steel curtain wall damaged more seriously

Many weathering steel curtain wall products are used in the manufacturing industry. If the weathering steel curtain wall is damaged due to incorrect practical operation, what are the actual benefits of damaging the weathering steel curtain wall? If there is a problem, we must master the problem and solve the difficulty. In this way, we can use weather-resistant steel curtain walls for longer during proper operation.
1. Harm of grindability index
If the grindability index is too small, the grindability will become worse, which will increase the damage to the weathering steel curtain wall of the wet ball mill.
2. The design scheme is not scientific, which is harmful to the installation quality.

The anchor bolt hole of the weather-resistant steel curtain wall of a fixed wet ball mill is square, which creates stress at this point and is prone to cracking at this position. The installation quality of weathering steel curtain wall is particularly important for the safe operation of wet ball mill.

3. The interaction between the weathering steel curtain wall and the bearing steel ball is destroyed
The weather-resistant steel curtain wall and bearing steel ball of the wet ball mill are the spare parts of the wet ball mill. When the ball mill is running, the weathering steel curtain wall will be damaged by the impact of the bearing steel ball and raw materials, and will also be damaged by the resistance of the bearing steel ball. In addition, the aging resistance of weather-resistant steel curtain wall increases with the increase of raw material strength. In addition, because the bearing steel ball and the weathering steel curtain wall are a pair of friction, the strength of one of them is increased, and the damage of the other is accelerated. Therefore, when the weathering steel curtain wall and bearing steel ball are properly selected to work together, the bearing steel ball can be weather-resistant, and at least the weathering steel curtain wall can be damaged.
4. Weathering steel curtain wall materials and heat treatment methods do not meet the requirements
High manganese weathering steel curtain wall The tensile strength of high quality weathering steel curtain wall is low, and it is easy to produce plastic deformation under the collision and grinding of the bearing steel ball and coal during the working process of the ball mill. Even because of this, the square anchor bolt of the wet ball mill is subjected to considerable shear stress, resulting in frequent breakage of the anchor bolt used to fix the weathering steel curtain wall.

5. Hazards of work load
The mill's lack of immediate adjustment of the coal feed rate of the wet ball mill will result in less coal during the operation of the wet ball mill. Some bearing steel balls will immediately rub and collide with the weathering steel curtain wall, and the impact force will be much larger than normal, which will damage the weathering steel curtain wall. It aggravates and immediately damages the service life of the weathering steel curtain wall.
6. Shortcomings cannot be eliminated immediately
Once the weathering steel curtain wall of the wet ball mill is broken or the anchor bolt is broken, if it is found that it is not removed immediately, it will damage other weathering steel curtain walls, or cause the head to deform more seriously when it is deformed.
