Bearing steel ball is a very important basic components, bearing in the use of the more important part of the bearing, this product is also the most widely used in the rolling bearing industry. Precision bearing steel ball plays an important role in people's economic development, because the quality of bearing steel ball directly affects bearing quality. The popularization and application of bearing steel balls not only promoted the development of ball manufacturing industry, but also promoted the development of artistry and the continuous development of science and technology in the relevant industries.
What are the quality indexes of bearing steel balls?
1. Bit cement ball consumption is low
2. ball rate
3. The surface of the steel ball is smooth, the area of the sprue riser accounts for the total surface area of the steel ball, which can reduce the invalid wear of the steel ball at the sprue riser, which also helps to reduce the energy consumption and enhance the production yield. This is one of the key criteria for identifying the level of forging balance that manufacturers have.
Bearing steel ball in the process，the main use of leading forging process equipment is the first premise, the use of the world's leading anhydrous production process, that is, the use of completely dry resin sand deposited on the metal film, completely get rid of glass water may Caused by stomatal, slag and other forging problems, so that product quality has a good Pentium; and improved iron-carbon ratio, try to adapt to the needs of quenching.
After the ball bearing production process that ball automatic cleaning, automatic appearance inspection (automatic removal of non-standard products), automatic rust-proof, counting packaging, all are the focus of the ball quality. Ball bearing ball bearing outer surface inspection process is indispensable ammonia support process. Bearing steel ball test should include the appearance of scratches, rust, surface spots and other aspects of testing.
