Lub tog zaum tso lub tog zaum yog kho cua sov nrog ib qho induction hardening tshuab. Qhov tshwm sim yog dab tsi?

Cov khoom siv ntawm lub rooj zaum tso tawm feem ntau yog No.45 steel, uas yuav tsum tiv taus kev sib txhuam loj thaum ua haujlwm. Yog li ntawd, qhov yuav tsum tau ua rau nws hauv kev tsim khoom thiab lub neej yog qhov siab, xav kom nws muaj qhov nyuaj, ua haujlwm hnyav thiab ua haujlwm ntev. Vim li no, ntau lub tuam txhab siv cov tshuab ua kom tawv tawv rau kev kho cua sov. Hnub no, kuv yuav qhia koj tias cov txiaj ntsig kev kho cua sov zoo li cas.

(1) High-frequency rapid heating of temperature changes will change the critical point temperature in the steel, which will increase the Ac3 line. Under normal circumstances, the high-frequency quenching temperature of No. 45 steel is 890-930℃, and water quenching and oil cooling are used. When circulating water is used as a cooling medium, in order to prevent cracks, the quenching heating temperature must be lowered. The recommended value is 820-860℃.

(2) The change of heating time When high-frequency hardening machine is used for heat treatment, increase the output power, reduce the heating time and the size of the inductor gap, and the depth of the hardened layer that meets the technical requirements can also be obtained.

(3) Tus qauv qub yuav tsum tau siv cua sov kom nrawm nrawm kom ua rau cov tshuaj austenite tsis sib xws, thiab cov qauv qub muaj feem cuam tshuam rau homogenization ntawm austenite. Yog li ntawd, lub rooj sib cais sib cais lub rooj yuav tsum tau ua kom zoo ua ntej tso zis ntau zaus txhawm rau Ua kom zoo ib yam thiab faib cov carbides zoo yuav pab ua homogenize austenite thaum cua sov nrawm, yog li zam kev tawg.

(4) Multi-turn inductor Cov cua sov ua tau zoo tuaj yeem txhim kho los ntawm kev siv ntau qhov tig inductor.
