NTN bearing cooling medium choice :                                                             

NTN bearing parts of the chemical composition, shape, size, and design requirements of the mechanical function of the different, a different method of quenching can be used, each NTN Bearing steel fixed C curve, the cooling medium to determine the microstructure after quenching and mechanical function, so the necessary key consideration and detailed analysis of, in fact, many NTN bearing parts of the heat-treated defect generated have a direct relationship with the choice of cooling NTN Bearing medium, also related to the detailed manipulation process.
After the workpiece in the heat treatment furnace is heated to a fully austenitic, to obtain a desired tissue and function, the need for the quenching treatment. After cooling of the workpiece to obtain martensite, the cooling rate must be greater than the critical cooling rate, cold excessive speed so that the volume shrinkage of the workpiece and organizational changes violently, causing great stress. Therefore, in obtain martensite premise should the cooling rate is as low as possible.
Select a suitable quenching medium display is particularly important, it is the decision of the the NTN bearing parts after quenching the organization and function, the quenching medium usually three kinds of solid, liquid and gas, NTN Bearing quenching medium of state changes into fat biological state changes biological and non-state change classes.
