Waa maxay Deminta Soo noqnoqoshada Sare?

Deminta soo noqnoqoshada sarewaxaa inta badan loo isticmaalaa deminta dusha sare ee qaybaha biraha warshadaha.Waa nooc ka mid ah habka daawaynta kulaylka birta ah taas oo ka dhigaysa dusha workpiece inay soo saarto hadda la kiciyay, si dhakhso ah u kululeeya dusha qaybaha, ka dibna si dhakhso ah u demi. qalabka.

Mabda'a kuleyliyaha induction: Qalabka shaqada waxaa lagu dhejiyaa dabaysha oo leh tuubo naxaas ah oo bannaan oo dareere ah, ka dib markii la helo soo noqnoqoshada dhexdhexaadka ah ama soo noqnoqda sare ee hadda jira (ac), oo lagu sameeyay dusha sare oo leh inta jeer ee hadda la soo kiciyay, dusha shaqada ama kulaylka degdega ah ee maxaliga ah (dhowr ilbiriqsi ilaa heerkul ah 800 ~ 1000 ℃, xudunta udubdhexaadku wali waxay ku dhowdahay heerkulka qolka) isla markiiba dhowr ilbiriqsi ka dib si deg deg ah u buufi (maquufin) qaboojinta biyaha (ama buufin qaboojinta saliidda qubeyska) dhamaystir shaqada dabka immersion, Samee dusha workpiece ama maxaliga ah si loo gaaro shuruudaha qalafsanaan u dhiganta.

Marka la barbardhigo kuleyliyaha caadiga ah, waxay leedahay:

1. Xawaaraha kuleylku waa mid aad u dhakhso badan, kaas oo ballaarin kara kala duwanaanta heerkulka kala-guurka jirka oo soo gaabiyo wakhtiga kala-guurka.

2. Martensite aad u fiican oo loo yaqaan 'cryptocrystalline martensite' ayaa laga heli karaa dusha sare ee shaqada ka dib marka la demiyo, iyo adkaanta wax yar ayaa ka sarreeya (2 ~ 3HRC) .Jajabka hooseeya iyo xoogga daalka sare.

3. workpiece ee lagu daaweeyaa habka ma fududa in oxidize iyo decarbonize, iyo xataa qaar ka mid ah workpiece si toos ah la isugu ururin karaa oo loo isticmaalo ka dib markii processing.

4, lakabka adkaanta waa qoto dheer, fududahay in la xakameeyo hawlgalka, fududahay in la ogaado makaanikada, otomatiga.

5, daminta dabka oogada ololka

Deminta soo noqnoqoshada sare ayaa lagu dabaqaa qalabka shaqada kaas oo u baahan inuu qaado ficilka culeyska beddelka ah sida torsion iyo foorarsi.Waxay u baahan tahay lakabka dusha sare si uu u qaado cadaadis sare ama xirto iska caabin ka badan xudunta, iyo dusha sare ee shaqada ayaa u baahan in la xoojiyo.Waxay ku habboon tahay birta leh kaarboonka We = 0.40 ~ 0.50%.
