20Crmnmo alloy steel phiaj yog ib hom qis dua cov khoom siv tseem ceeb xws li cov qauv siv tshuab hluav taws xob tseem ceeb, muaj zog, muaj zog, thiab hnav tsis kam. Hauv qab no yog cov ncauj lus kom ntxaws ntawm lawv cov yam ntxwv tseem ceeb, kev siv, kev txiav txim siab, thiab cov ntaub ntawv muaj feem xyuam:

 

 

Cov Kev Siv Raug Raug

Vim nws lub zog siab, lub zog zoo, thiab hnav tsis kam tom qab kev kho cua sov, 20crmnmo alloy steel phiaj tau siv nyob rau hauv:

 

Kev Lag Luam Automotive: Gearboxes, drive shafts, differential gears, and other load-bearing transmission parts.

Machinery raug: High {{{{{}} Lub zog lub zog, thiab hnyav - Dos dej I.

Aerospace thiab engineering machinery: Cov txheej txheem uas yuav tsum tau ua rau cuam tshuam rau kev cuam tshuam thiab kev qaug zog.

 

 

 

 

 

 

Ua Kev Saib Xyuas

A. txiav ua

Tuam Xaiv: Siv high - ceev steel (hss}}}}}}}} cov hlau lub zog thiab hnav tsis kam.

Txiav tej yam tsis yog:

Txiav ceev: 60-100 m / min rau cov cuab yeej carbide; 30-50 m / min rau cov cuab yeej hss.

Tus nqi pub: 0.1-0.25 mm / r; Txiav qhov tob: 2-4 hli (zam kev quab yuam ntau dhau los tiv thaiv cuab tam).

Cua txias thiab lubrication: Siv cov roj siab heev txiav roj lossis emulsion (muaj cov txiv neej thiab tshuaj txhuam hniav ntxiv) kom txo kev sib txhuam thiab cua sov, tiv thaiv kev ua haujlwm overheating thiab cuab tam.

Kev Tswj Xyuas Kev Ruaj Ntseg: Ua kom ntseeg tau cov cuab yeej clamping (piv txwv li, cov cuab yeej siv hydraulic kom tsis txhob co roughness (phiaj ra tsawg dua lossis sib npaug rau 1.6 μm).

 

 

B. Vuam Ua

Vuam Txoj Kev: Xav arc vuam cov txheej txheem xws li smaw (phau ntawv arc vuam), gtaw (tsov), lossis GMAW (MIG). GTAW yog tsim nyog rau lub hauv paus dhau mus rau qhov hws thiab swb rau kev sib cais.

Ua ntej - weld npaj:

Ntxuav cov chaw (kev sib tsoo txhua yam) los tshem tawm cov oxides, roj, thiab xeb (huv si 20 mm ntawm ob sab ntawm 坡口).

Preheating: yuav tsum tau tiv thaiv kom tiv thaiv kev tawg txias. Preheat rau 150-250℃(kho raws li phaj tuab; thicker daim hlau xav tau kub).

Vuam cov ntaub ntawv: Siv qis - hydrogen electrodes txuam nrog lub hauv paus hlau, piv txwv li G (rau smaw) lossis ER80S-G (rau GMAW). Cov hluav taws xob qhuav ntawm 350℃rau 1 teev thiab khaws cia hauv 100-150℃tuav qhov cub.

Post -} Weld Kho:

Kev nyuaj siab txhawb nqa Annealing: cua sov txog 550-650 degree, tuav rau 2-4 teev, ces txias maj mam kom txo qis kev ntxhov siab.

Zam kev ua kom txias kom tiv thaiv brittleness; Ua tempering yog tsim nyog los rov ua kom nruj.
