Factors affecting the scrap cycle of dowty retarder

It is difficult to determine the scrap period of dowty retarder scientifically. The influencing factors are as follows.

The installation position and working condition of the dowty retarder affect the service life of the dowty retarder. The same type of dowty retarder is installed in the station with great difference in temperature, humidity and other climatic and natural conditions, and the service life of these dowty retarder is also different. The critical speed grade of dowty retarder installed in different positions in the same station and the rolling times of the retarder every day are also very different.

In the use and maintenance process, the dowty retarder is not always used as a whole, and the sliding cylinder assembly can be interchanged in any shell of the same grade, so the concept of rolling times of a certain top is not very clear, so in this case, the rolling times of shell and sliding cylinder are not necessarily the same.

The quality difference of various dowty retarder also determines that their service life indexes are not the same. The production process, material and heat treatment method of various dowty retarder and the dowty retarder items produced by various manufacturers are different, which determines the scrapping cycle of dowty retarder is also different.
