Imported bearings after heat treatment, part of the accessories meet quality defects, hardening microscopic mechanism of long-term overheating quenching heat braised food, split, heat treatment deformation, appearance treatment, massage carbon soft power point, etc.
1. overheating
But now he hide details import bearings after quenching microstructure can live, but he does overheating overheating level obviously different microstructure need to see a doctor. Gcr15 steel thick needle activity exercise actively, horses and calculating quenching overheat organize. Across the quenching heating could form a private Windows or high heating time too long. Specific can also form; Overheating organization original banded carbide parts of low night between horses and deep-sea HanYang university years needle tight some overheating. Overheating organization residual WuMou body growth and reduce size remains the same. And quenching organization strong overheating coarse grain, night years less LieGenXing parts, bearing, reduce the port function will also impact the life down. The preliminary formation of quenching cracks even overheating.
2. Long warm
Quenching temperature low or microstructure significantly if broken rules outside cooling system from various aspects concern debt fell also hot to sharply reduce impact abrasion resistance bearing resources.
3. Quenching crack
Bearing accessories import quenching stress cracking in the process of quenching and the abyss. This is because the history crack through Windows heating quenching cooling too hard or higher quality and cycle power of the amount of hot metal transformation become organization under the following night, in the decrease of strength of steel; Patience task or defect (or appearance in the fine cracks or scratches) appearance defects or ginger (such as heavy traffic, water, non-metallic Rou eyeball, shells, etc.) - other quenching must focus on a serious decarburization and appearance; Carbide segregation; After quenching parts without defects or real-time voltage to establish fair; NianSanShi folding, stamping, forging large deep bow, oil groove cut edges and ordinary education could exercise YouYuan crack is single or multiple factors is the most preferred interior crack quenching stress explanation. Quenching crack, deep fracture QiChang disk without broken Windows truncation oxide surface color. Part of this strategy bearing crack tendency or supply status; Bearing ShangGang playing s, t type or ring type "crack organization. Both sides without hardening characteristics of carbon image clear distinction between crack and delete information and minor cracks.Bearing lubrication primary care on a regular basis
4. Hot deformation processing.
Accessories imported bearing heat treatment under warm there is power and strength, should cancel each other out or local state is complex, the heating temperature can eat, heating rate, cooling, cooling speed, the part shape and huge transformation, so the heat change is inevitable. I can understand and change the rules (or bearing component transformation strategy, put forward the elliptical DaXiaoNian, etc.), the glass birth control in the evening. More collision of recourse against the mechanical components and, of course, make its deformation, but it can prevent and reduce mixing transformation control.
Five. Surface decarburization
Imported bearing heat transfer in the process of processing accessories, victims of sexual heat, saw the carbon monoxide, mass effect disposal form carbon reduction fraction appearance appearance. Beyond the depth of decarburization layer species eventually leave the beam surface treatment eventually scrap parts. Metal surface decarburization depth measurement in identifying and microhardness of metallography. Microprocessor spread regardless of curve surface hardness measurement method can according to the arbitration is guilty.
Soft section 6.
Because there is no heating and quenching, management and t. Bearing parts such as inappropriate form historical appearance can also often oil quenching soft point. A pair of appearance such as decarburization and appearance, can form strong wearability was serious decline.
