Xinjiang urumqi frequently the cause of the mysterious events bearing manufacturer

Xinjiang urumqi bearing manufacturers often causes a mysterious events, high temperature bearing the original bearing the original data is mixed, osteoporosis, brittle element segregation or carbide liquid chromatography, mesh, ribbon, not survived well partial defects such as in processing work will not be offset or improvement, will form stress concentration, weaken the ferrule fundamental strength, become the source of crack. Prevention method is to stick to supply of main channel, and try to shake robust qualities dumping of steel, increasing the incoming inspection of purchased steel, advice, bearing clearance should be from source. Second, the high temperature and the cost of the bearing and equipped with 1. Forging: if attacks burnt in the process of bearing forging, too warm, bearing inner crack into carbide network such as land ring of toughness and strength. So must have been a serious processing temperature, control loops and warm forging after scattered warm conditions ( Such as spray cooling) , such as special kind is larger ring after finish forging, the temperature is above 700 ℃, the shall not be piled up to put. 2. Warm warm disposal: the bearing disposal is a main workshop equipped with close monitoring. A record of the monitoring data. Required to restore the warm disposal with the temperature records of installation, so that the obligation to with the whole process ( Night shift key) Industrial invalid monitor, warm disposal quality have strong traceability, eradicate falsehoods and informality, at the same time supply condition to the ISO9000 quality system data. Quenching cooling conditions. To deal with soft point defects such as large type bearing ring, should determine the composition and function of quenching oil not begged to advance to change, to the rapid quenching oil replacement, to enhance quenching medium for hardening ability, improve quenching cooling conditions. Serious tempering process. For fracture is more kinds, in the ring after coarse grinding stagnation secondary tempering, it can be further shake ring organization and size, can decrease again ooze grinding stress, improve the grinding function evolution layer. Has recently on 22328/02 and 22236/02 two kinds of secondary tempering process, to after-sales tracking reflect textual research. 3. FAG bearing grinding process monitoring. Waste bearing ring grinding burn and grinding cracks do not allow exist, special inner ring is changed with the taper surface must not have burns. If ring should be stagnant all inspection after pickling, picking burns products, severe burns can't repair or repair the exam should be discarded, do not allow a grinding burn ring into the assembly process. 4. Identity management, after bearing steel storage to the front of the ferrule grinding, each working procedure must be serious management, serious distinguish GCr15 and GCr15SiMn two different material data and products. A: remember the three tricks, he no longer panic next up: for the manufacturer of bearing ring is easy to break in Lhasa Tibet you guessed it
