Principles of Optimal Selection and Operation of Bearing Steel
The operational properties of mobile units of equipment depend to a large extent on the accuracy, durability and reliability of bearings.
Bearing steels produce balls, rollers, bearing rings, stop valves, pushers and other parts requiring high hardness, wear resistance and contact strength.
When choosing the steel grade required for use, its microstructure, the presence and nature of non-metallic inclusions, the depth of hardness and decarburization are taken into account. These parameters are controlled exclusively for the steel carrier.
Decarburization of finished bearings is not allowed. If the surface of the ball is decarburized, friction in the bearing increases due to crushing of the ball surface under load, the bearings heat up and collapse. Hot-rolled steel is commonly used in the production of bearing rings.
The structure of the incoming billet significantly affects the quality of the finished bearings. The billet should have a uniform globular pearlite structure. When the bearing steel is heated to 800 ° C, fine grains dissolve, and coarse grains remain. With further slow cooling large carbides grow. As a result, the steel structure looks like a heterogeneous coarse-grained perlite. Rough carbides affect the quality of the hardened ball. The continuity of the bearing steel can be increased by adding 0.40… 0.65% silicon and 0.9… 1.2% manganese. Carbide net or its residues sharply reduce the viscosity of hardened balls, which causes fracture under impact load.
