Common Forms of Fracture

Thaum lub sij hawm coiling, txias-draw caij nplooj ntoos hlav steel hlau tawg feem ntau nyob rau hauv ob hom:

Cov pob txha tawg: Cov pob txha tawg yog tiaj tus thiab crystalline, tsis muaj qhov pom tseeb ntawm cov yas deformation ua ntej tawg.

Ductile tawg

Cov theem ntawm Fracture tshwm sim

Nyob rau theem pib ntawm coiling: Cov hlau tuaj yeem tawg vim muaj qhov tsis xws luag xws li cov kab nrib pleb los yog cov khoom siv sab hauv uas tsis tuaj yeem tiv taus qhov kev ntxhov siab thaum coiling.

Thaum lub sij hawm coiling txheej txheem: Raws li coiling zuj zus, khoov kev nyuaj siab, torsional kev nyuaj siab, thiab lwm yam, tsub zuj zuj nyob rau hauv cov hlau, thiab pob txha tawg tshwm sim thaum qhov kev ntxhov siab tshaj nws cov kabmob muaj peev xwm.

· Thaum lub sij hawm ua tom ntej los yog siv tom qab coiling

Khoom tsis zoo

· 

Internal Defects: Aggregation ntawm nitrides nyob rau hauv cov qauv 破坏 (destroys) cov khoom txuas ntxiv, tsim cov cheeb tsam uas tsis muaj zog uas yuav ua rau tawg nyob rau hauv sab nraud rog. · 

Kev Ua Haujlwm Tsis Zoo: Cov khoom siv ntau dhau lub zog txo nws cov npoo yas. · 

Cov Teeb Meem Technology

:

· Lub vojvoog me me dhau thaum lub coiling ua rau lub zog tensile ntau dhau ntawm sab nraud ntawm cov hlau, ua rau tawg thaum muaj kev ntxhov siab tshaj nws lub zog tensile.

· Khoom siv thiab tuag teeb meem:

· Qhov tseeb thiab ruaj khov ntawm cov khoom siv coiling cuam tshuam rau cov hlau zoo.

· Kev tsim thiab tsim khoom zoo ntawm cov tuag kuj tseem ceeb heev.

· Lubrication tsis txaus thiab txias:

· Lub lubrication zoo thaum coiling txo kev sib txhuam ntawm cov hlau thiab cov tuag, txo qhov kev puas tsuaj ntawm qhov chaw.

· Cov cua txias tsis txaus kuj ua rau cov hlau kub ntau dhau thaum coiling, cuam tshuam rau nws cov microstructure thiab cov khoom, thiab ua rau muaj kev pheej hmoo tawg.

Environmental Factors

· Kub thiab av noo:

· Tsis tshua muaj kub ambient txo cov hlau lub toughness thiab tsub kom brittleness, ua rau nws yooj yim rau tawg thaum coiling.

· high humidity ua rau nto xeb ntawm cov hlau;

· Corrosive Media:

· Yog hais tias lub caij nplooj ntoos hlav txias txias steel hlau yog coiled nyob rau hauv ib puag ncig nrog corrosive media (piv txwv li, acidic los yog alkaline daws), tshuaj lom neeg tshwm sim ntawm cov hlau nto, ua rau corrosion.

Kev Tiv Thaiv Kev Tiv Thaiv Kev Txhaum Cai

Kev Tswj Xyuas Khoom Zoo

Thaum muas lub caij nplooj ntoos hlav caij nplooj ntoos hlav steel hlau, ua kev soj ntsuam nruj ntawm cov khoom siv raw, suav nrog tshuaj lom neeg tshuaj ntsuam xyuas, ntsuas cov cuab yeej cuab tam, kuaj cov qauv metallographic, thiab tshuaj xyuas qhov zoo. · Kev soj ntsuam nruj raw khoom:

Xaiv lub caij nplooj ntoos hlav caij nplooj ntoos hlav steel hlau tsim nyog raws li lub caij nplooj ntoos hlav daim ntawv thov thiab ib puag ncig ua haujlwm.

· Tsim nyog kho Coiling Parameters:

· Tswj thiab txhim kho cov cuab yeej thiab tuag:

· Txhim kho Lubrication thiab txias tswj:

Txhim kho Environmental Conditions

Txhim kho qhov kub thiab av noo tswj cov cuab yeej hauv lub rhiav kom muaj qhov sib txawv.

· Zam Corrosive Ib puag ncig:

Xaus

Kev tawg ntawm lub caij nplooj ntoo hlav steel hlau thaum lub sij hawm coiling yog ib qho teeb meem nyuaj uas cuam tshuam nrog cov khoom tsis xws luag, teeb meem kev siv tshuab, thiab ib puag ncig.
