Note the use of rolling a wheel, rolling machine accuracy, vibration, does not operate under normal service; 2, rolling die on the bit error, is the occurrence of axial displacement of the rolling element rolling wheels wholesale, tooth pattern subjected to shear Both stress and extrusion; 3, is uneven rolling green silk thread size, the surface is not clean rolling wheels with wheel foam, scale and filth; 4, uneven hardness is rolled pieces ( 8.8 bolts should be at 27 ~ 30HRC; 10.9 level applications in 35 ~ 37HRC), sometimes because of mismanagement will prevent without tempering high hardness (50 ~ 55HRC) quenching and tempering pieces blend into pieces, and its hardness and roll wire wheel tooth pattern edge hardness similar, leading to chipping. 5, did not join when rolling lubricant, causing friction, so cusp rapid temperature rises above rolling cycle of fire temperature MassMutual rolling wheel, excessive temper softened tooth pattern, the occurrence of back teeth, tooth stack failure; the first six, rolling round the factory must be fully demagnetized, leaving residual magnetism, work fine iron absorption due to tooth pattern foam will accelerate wear failure. Rolling wheels rolling wire wheel bore within the high-frequency induction hardening and tempering using spiral inductors bore quenching, with intermittent electricity ways to make the hole about 0.5mm depth is heated to about 1050 ℃, air cooling rolling wheel Manufacturers and 480-500 ℃ X2h tempering hardness after heat treatment ≥45HRC, narrow bore 0.03-0.05mm, after grinding to achieve the pattern size requirements. Quenching and tempering the hole before rolling wheels arranged in cone quenching.
