Description
Technical field
The present invention relates to the processing technique field of Corrugator roller, specifically the processing method of a kind of Corrugator roller.
Background technology
Corrugator roller be corrugated case produce core component, be also consumable accessory, directly influence production cost and the benefit of Carbon enterprise its service life, be each Carbon enterprise maximum be also most important equipment consumption costs expenditure. Conventional Corrugator roller processing technique is: the roll body of Corrugator roller selects 48CrMo material modified, welds spindle nose and cylindrical roughing, roughly grinds tooth punching, lonneal after mid frequency induction hardening, tooth face hardness about HRC53, finishing grinding tooth, flank of tooth hard chrome plating or spray tungsten-cobalt alloy. This technics comparing is ripe, operates fairly simple, quenching infiltration layer depth; But roll flute workload strengthens, it is necessary to front and back are installed roll flute for twice and completed; If mid frequency induction hardening tooth face hardness is too high, it is easy to cracks in tooth surface occur, fall the phenomenons such as tooth, if tooth face hardness is too low, then anti-wear performance is poor, and service life shortens, and mid frequency induction hardening makes watt roller internal stress big, yielding. Again repairing hard chrome plating or spray tungsten-cobalt alloy after can only refining, tooth face hardness reduces, and the life-span significantly shortens, and so generally can only repair 12 times; The flank of tooth can be made to produce relatively deep torn grain because of liberation of hydrogen during hard chrome, occur time serious sticking up wing tooth, falling tooth phenomenon and make a watt roller destroy.
