Converter bearing role to be reckoned with in rotary joints - bearing knowledge

Converter rotating joint is not as popular as other rotary joint, installed in a steel plant of converter trunnion part of help converter connecting pathways the connected piping, transfer the required cooling, bottom blowing and basic medium, guarantee in the process of production, uninterrupted water aeration to realize to the converter trunnion, for cooling, in areas such as the furnace cap for the converter bottom blowing argon/nitrogen, also to air cooling of bosh, because the main function on the converter, so called converter rotating joint, is an important part of a guarantee for safety in production of converter.     Bearing support in the converter rotating joint and the effect of rotating and ensure concentricity, joint bearing is good or bad will directly affect the performance and the use of life; Inferior bearing surface rough, uneven chamfer, work when there is a noise, bearing inner and outer ring of the curvature ratio is out, resulting in the insufficient concentricity; Rotary joint sound bearing internal impurities, when bearing rotate faster work a long time will be stuck, the inside of the joint ball broken cause bearing does not spin, if the rotor of the rotating joint weight is too big, poor quality of the bearing is easy to be bad rotor gravity pressure, rotary joint wouldn't turn at this time, one more thing, bearing impact concentricity of fitting clearance will increase at the same time, the greatest manifestation is swinging, abnormal directly do not change the rotary joint, can observe more, may change as long as a parts can.     Converter rotating joint work environment is relatively poor, poor bearing easy to rust, high temperature environment bearing is easy to deformation, a price a points goods, good bearing prices relatively high, so don't care about save a little money to buy, may delay event.
