Cov hauv qab no yog cov txheej txheem rau kev kho cov txheej txheem kev kho cua sov ntawm CCS A420 steel hauv ntau daim ntawv thov lossis kev lag luam:

Shipbuilding thiab Marine Engineering

 

Kho cov txheej txheem quenching thiab tempering: Rau CCS A420 steel siv nyob rau hauv kev tsim cov txheej txheem tseem ceeb ntawm lub nkoj hulls, xws li nkoj daim hlau thiab keels, quenching thiab tempering tshav kub kho tau txais yuav. Lub quenching kub yog feem ntau ntawm 900 degree thiab 950 degree. Lub sijhawm tuav yog txiav txim siab raws li lub thickness ntawm lub workpiece. Feem ntau, nws yog tuav li 1 teev rau txhua txhua 25 hli thickness, thiab ces roj quenching yog siv. Qhov kub thiab txias yog nyob nruab nrab ntawm 600 degree thiab 650 degree, nrog lub sijhawm tuav ntawm 2 - 3 teev, thiab cua txias tuaj yeem siv tau. Nyob rau hauv txoj kev no, cov hlau tuaj yeem tau txais cov khoom zoo txhua yam, txhim kho nws lub zog thiab tawv, thiab ua tau raws li qhov yuav tsum tau siv rau hauv qhov hnyav marine ib puag ncig.

 

Kev lag luam kev tsim kho

 

Kev kho mob Annealing: Yog tias CCS A420 steel siv rau cov hlau loj loj hauv kev tsim kho, xws li choj girders thiab txhua kab ntawm cov tsev siab, kev kho annealing tuaj yeem nqa tawm ua ntej ua haujlwm. Qhov kub annealing feem ntau yog nyob nruab nrab ntawm 780 degree thiab 820 degree, nrog lub sijhawm tuav ntawm 3 - 4 teev, thiab tom qab ntawd nws maj mam txias hauv qhov cub rau hauv chav sov. Annealing tuaj yeem txo qhov hardness ntawm cov hlau, txhim kho nws cov kev ua tau zoo, thiab ib txhij tshem tawm cov kev ntxhov siab nyob hauv cov hlau, txo qhov kev pheej hmoo ntawm deformation thaum lub sij hawm ua tom qab thiab siv.

Machinery Manufacturing Kev Lag Luam

 

Nto quenching: Thaum CCS A420 steel siv los tsim cov khoom siv kho tshuab, xws li lub zog thiab cov ncej, thiab nws yog qhov tsim nyog los txhim kho qhov tawv tawv thiab hnav tsis kam, cov txheej txheem deg quenching tuaj yeem siv tau. Piv txwv li, induction cua sov saum npoo quenching tuaj yeem siv los ua kom sov ntawm qhov chaw ntawm qhov kub ntawm 900 degree thiab 950 degree, thiab tom qab ntawd cov tshuaj tsuag txias yog nqa tawm los ua txheej txheej tawv. Tom qab ntawd, qhov kub thiab txias tempering yog nqa tawm. Lub tempering kub yog nyob nruab nrab ntawm 180 degree thiab 220 degree, nrog lub sijhawm tuav ntawm 1 - 2 teev, uas tuaj yeem txhim kho qhov tawv tawv, hnav tsis kam thiab qaug zog, thaum lub hauv paus tseem ceeb ntawm cov khoom tseem muaj zog zoo.

Carburizing thiab quenching: Rau qee qhov chaw uas yuav tsum tau muaj qhov tawv tawv tawv, hnav tsis kam thiab qaug zog ua haujlwm zoo, xws li lub zog hauv kev xa tsheb, cov txheej txheem carburizing thiab quenching tuaj yeem siv tau. CCS A420 steel yog tuav nyob rau hauv ib qho chaw carburizing ntawm qhov kub ntawm 920 degree thiab 950 degree rau ib lub sij hawm ntawm lub sij hawm kom cia carbon atoms nkag mus rau hauv lub nto ntawm ib feem thiab tsim ib tug tej yam tob ntawm carburized txheej. Tom qab ntawd quenching thiab low-temperature tempering yog nqa tawm. Qhov tob ntawm carburized txheej yog feem ntau ntawm 0.8 hli thiab 1.2 hli. Lub quenching kub yog nruab nrab ntawm 880 degree thiab 920 degree, nrog roj quenching, thiab tempering kub yog nyob nruab nrab ntawm 180 degree thiab 220 degree.
