Camshaft induction cua sov thiab quenching txheej txheem

Tom qab cov qauv ntawm lub tshuab quenching yog txiav txim siab, 8 cam induction cua sov quenching txheej txheem txheej txheem yog txiav txim. Cov txheej txheem no yog tias lub workpiece nkag mus rau hauv inductor, thiab lub workpiece yog energized rau cua sov ib zaug. Tom qab lub workpiece tawm ntawm inductor, nws raug xa mus rau qhov nruab nrab quenching, thiab cov kua immersion yog txias thiab quenched. . Cov txheej txheem tsis siv hauv quenching yog qhia hauv Table 2 .
Table 2 Camshaft induction cua sov thiab quenching txheej txheem tsis

Hluav taws xob tsis							Lub sij hawm parameter /s		Quenching nruab nrab
DC voltage / V	DC tam sim no / A	Intermediate zaus voltage / V	Lub zog muaj zog / kW	Peev xwm /uF	Transformer tig ratio	IF zaus / kHz	cua kub	Ua ntej txias	Concentration (%)	Kub / ℃	Stirring twj tso kua mis qhov hluav taws xob siab / MPa
380	800	620	350	180	18 / 1	3.7	13	2	11	10-40	0.4

Yuav tsum muaj qee qhov hluav taws xob seem thaum lub quenched workpiece raug rau cov kua nto, yog li ntawd cov residual cua sov yuav siv tau rau tempering kom tshem tawm cov quenching kev nyuaj siab. Muaj ob txoj hauv kev los tswj qhov kub ntawm lub workpiece. Ib qho yog los kho lub sijhawm nyob ntawm qhov chaw ua haujlwm hauv qhov nruab nrab quenching, uas tuaj yeem ua tiav los ntawm kev hloov qhov ntev ntawm lub sijhawm txav mus los ntawm lub conveyor 6. Lwm txoj kev yog hloov qhov concentration ntawm quenching nruab nrab. Tus neeg sawv cev quenching peb siv yog 8-20 dej-soluble quenching tus neeg saib xyuas, thiab nws lub peev xwm txias yuav txo qis thaum cov concentration nce.
