In the machinery industry, especially in the mechanical maintenance industry, many precision bearing steel balls are purchased at one time. The precision bearing steel balls play an inestimable role in the bearings, and the quality of the bearing steel balls directly affects the service life of the bearings. Then what technical indicators should be paid attention to when buying bearing steel balls.
1, unit steel ball energy consumption
2, the ball rate
3. The surface of the demanding steel ball is smooth, and the area of the pouring riser accounts for a small total surface area of the steel ball, which can reduce the ineffective wear of the steel ball at the pouring riser, and also helps to reduce energy consumption and enhance production output. This is one of the key criteria for identifying the level of forging balance that manufacturers have.
Because of the development of China's machinery industry in these years, the market capacity of precision bearing steel balls has also expanded at the same time. Each company and investors are bearing the bearing of the steel ball market. So what are the prerequisites for investment bearing steel ball production companies?
The first one: the leading forging process equipment is the primary premise, using the international leading water-free production process, that is, using completely dry resin sand on the metal film, completely removing the pores, slag inclusions, etc. caused by the moisture of the water glass. Forging problems, the quality of the product has a quality Pentium; and improved the iron-carbon ratio, try to adapt to the quenching needs.
On the other hand: the post-procedure of precision bearing steel ball production, namely automatic cleaning of steel balls, automatic appearance inspection (automatic removal of non-standard items), automatic rust prevention, counting and packaging, are all the key factors affecting the quality of steel balls. The appearance inspection of the bearing steel ball is a process of indispensable ammonia in the process of steel ball processing. The bearing steel ball appearance inspection should include the detection of surface scratches, rust, surface spots and the like.www.wxjnsteelball.com
