What kind of alloy casting ball is suitable for cement industry Release time:2020-10-21     Views
Alloy casting balls are widely used in powder preparation and ultra-fine deep processing of cement building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coatings, light industry papermaking, magnetic materials and other industries.

  The following is the alloy casting ball related content, let's have a look!

  What kind of alloy should be used in ball casting industry?

  Alloy casting balls are widely used in powder preparation and ultra-fine deep processing of cement building materials, metal mines, coal slurry thermal power, chemical engineering, ceramic coatings, light industry papermaking, magnetic materials and other industries. The product has high hardness, low abrasion, good toughness and less crushing. In the process of use, the surface hardness of the ball will be further improved, and the wear resistance will be enhanced. At the same time, the production capacity of the mill can be improved, and the specific surface area of cement and the recovery rate of concentrate can be improved.

  What kind of alloy casting ball is used in the construction industry?

  In terms of chemical composition, there are dozens of different materials from low chromium to high chromium. In order to standardize the industry standard and let people have a clear understanding of chromium alloy casting ball, the national standard GB / t17445-2009 stipulates that the content of low chromium ball chromium is 1% - 3%, and the hardness is HRC ≥ 45; the content of multiple alloy ball chromium is 4% - 6%, and the hardness is HRC ≥ 47; the content of medium chromium alloy ball chromium is 7% - 10%, and the hardness is HRC ≥ 48; the content of high chromium alloy ball chromium is ≥ 10% - 14%, and the hardness is HRC ≥ 58; The chromium content of special high chromium ball is more than 14%, and the hardness is HRC ≥ 58.

  High chromium alloy casting balls are not only environmentally friendly but also wear-resistant

  At present, high chromium ball is the main grinding medium used in cement industry in China. With the continuous development of cement grinding technology, the requirements of specific surface area and fineness of cement are higher, so it is very important for cement enterprises to select the right grinding materials. The abrasive body with high wear resistance can not only improve the grinding efficiency, reduce the time and times of ball repair and start-up and stop times, but also prolong the cleaning cycle and reduce the labor intensity of workers. At the same time, it is of great significance to improve the mill output per hour, ensure the abrasive quality, and reduce the power consumption and grinding body consumption. The chromium based alloy casting ball products are developed in combination with different industries and working conditions. The forging hardness of high chromium ball for cement mill reaches above 62Hrc (impact value ≥ 4.0j/cm2). In many large-scale cement enterprises in China, the unit consumption per ton of cement in a single bin is only about 13g. Compared with the same period of the same period, the wear resistance of the cement mill is lower, and the chromium ball is increased by more than five times, which creates super value economic benefits for the cement enterprises. It can be described as the real environmental protection grinding ball and green grinding ball.
