Rolling mill bearing Also known as induction heating power induction heater, also known as induction heating equipment, all collectively work piece is heated both involve induction heating include: induction heating power supplies, induction heating equipment, roughness measuring instrument bearing heater, bearing induction heater, including industrial after preheating induction heating power supply piping hot, Evaporation, copper brazing used, the basic working principle is to use alternating current generates an alternating magnetic field, the alternating magnetic field which is generated inside the metal conductor eddy (eddy current), heat rapidly so that the metal of the workpiece, in general, the heating effect, there is a frequency, a current, a magnetic field joint decision.
In induction heating, the temperature rise of the workpiece to be heated is a metal part, there will be induced heat the heater itself, most of the work to be induced through the use of cooling water to cool the heated portion of the workpiece is not a non-metallic heat .
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
