Iimpawu ze-welding zentsimbi engenasiseko i-austetitic: uxinzelelo lwe-elastic kunye neplastiki kunye noxinzelelo lwenkqubo ye-welding inkulu kakhulu, kodwa kunqabile ukuba kusetyenziswe izifuba ezibandayo. Akukho ndawo yokuhamba nzima i-quench yokuqinisa kunye nengqolowa ebalekayo kumdibaniso we-Weldied, ngoko ke amandla e-sunser of Weld iphezulu.
Ezona ngxaki ziphambili ze-austitic yensimbi ye-welding yensimbi yentsimbi: Ngenxa yemida yobukumkani bokuzibhokoxa kunye neemvakalelo zokungcola okuthile (s, p), kulula ukuvelisa imifuno eshushu.
Iingxaki ezintlanu eziphambili ze-welding kunye namanyathelo onyango lwensimbi ye-austetitic
1. Ukuqulunqwa kwe-Chromium Carbide kunciphisa amandla okudibanisa amachiza okumelana nokungabikho komntu.
I-Trasion yoThengiso phakathi: Ngokomlomo we-chromium, i-chromium ye-chromium ye-chromium kwimida yobushushu ye-450-850 ℃, oko kungonelanga ukuxhathisa ukhuphelo.
.
Ukunciphisa umxholo wekhabhoni wensimbi yesiseko kunye ne-welds, yongeza izinto zokuzinzisa i-TI, i-NB kunye nezinye izinto kwinsimbi yesiseko ukunqanda ukwenziwa kwe-MC23C6.
b. Yenza ukuba i-WALD YAMNQOQOSHO KAKHULU KWI-AUSTENITE kunye nexabiso elincinci le-FERRIT. Xa kukho inani elithile lezinto ezifudumeleyo kwi-WRERT, iingqolowa zinokuhlaziywa, indawo yengqolowa inganyuswa, kunye nokuchama kwe-chromium carbide yendawo nganye ?? I-chromium inyibilikiswe kakhulu kwi-FRET. I-CRR23C6 ikhethekile ngokunyaniseka ngaphandle kokuzibhokoxa kwemida yokudla okuziinkozo eziza kupheliswa kwiChromium; Ukusasazeka phakathi kwama-Austedites kunokuthintela ukohlwaya umda kumda wokudla okuziinkozo kwilizwe langaphakathi.
c. Lawula ixesha lokuhlala kuluhlu lobushushu bemvakalelo. Adjust the welding thermal cycle, shorten the residence time of 600～1000℃ as much as possible, choose a welding method with high energy density (such as plasma argon arc welding), select a smaller welding heat input, and pass argon on the back of the weld or use a copper pad Increase the cooling rate of the welded joint, reduce the arc starting and ending times to avoid repeated heating, and the contact surface Ngomgangatho ophakathi ngexesha le-weldiayer ye-Multilayer kufuneka idlwengule njengoko kunokwenzeka.
d. Emva kokwenza i-welding, yenza uzinzo lwesisombululo okanye ukuzinza kwenziwe (850 ~ 900 ℃) kunye nomoya ukupholisa ukwenza i-carbides ihlawule kwaye ikhawuleze i-chromium).
. Ngesi sizathu, la manyathelo athile othintelo anokuthathwa:
Ngenxa yokukwazi ukwenza ikhabhoni eqinileyo, iyakuqala kumda wokudla okuziinkozo ukwenza imeko eqingqiweyo, ngelixa i-TI kunye ne-NB kunye ne-Tystal yamandla okukrelekrele. Xa i-Weldied Jikelele ishushu kwakhona kuluhlu lobushushu lwemvakalelo, ikharbon egqithisileyo iya kuthi ifumaneke ngohlobo lweCR23C6 phakathi kweekristali.
a. Ukunciphisa umxholo wekhabhoni. Kwinsimbi engenasibala equkethe izinto ezizinzileyo, umxholo wekhabhoni akufuneki ungadlula kwi-0.06%.
b. Sebenzisa inkqubo ye-welding ye-welding. Khetha igalelo elincinci le-welding le-welding lokunciphisa ixesha lokuhlala lendawo ephezulu kwiqondo lokushisa eliphezulu, kwaye unikele ingqalelo ekuthinteleni imvakalelo yokuthintela ' Xa ilokhwe enamacala amabini, i-weld inxibelelana ne-Corrosing kunye ne-Coulting Medium kufuneka ibe yeyokuthatha i-wels yokugqibela (Esi sisizathu sokuba imibhobho yangaphakathi ye-WelDeter yenziwa emva kwedls yangaphandle). Ukuba ayinakuphunyezwa, ukucaciswa kwe-welding kunye nemilo ye-weld kufuneka kulungiswe ukuphepha indawo egqithileyo ekunxibelelaneni ne-corrossive kunye nengqondo.
c. Unyango lwasemva kwe-Weld. Yenza isisombululo okanye unyango oluzinzileyo emva kwe-welding.
I-2. Uxinzelelo lokungasebenzi
La manyathelo alandelayo anokusetyenziselwa ukuthintela ukungabikho koxinzelelo ukucutha ukuvela kwenzeke:
a. Ngokuchanekileyo khetha kwaye ngokufanelekileyo uhlengahlengise ubume be-weld. I-chromium ephezulu ye-chromium-i-Nickel Austelitic yentsimbi, i-Silicon Chromitic Austenitic Austenitic, i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic-i-chromitic ye-chromitic inesitayile soxinzelelo. Intsimbi yesigaba sezigaba se-sterite kunye nefrrite.
b. Susa okanye unciphise uxinzelelo lwentsalela. Yenza unyango lwasemva koxinzelelo lwe-Weld-Ild
c. Uyilo lwesakhiwo esifanelekileyo. Ukuthintela uxinzelelo olukhulu.
I-3. I-Wolding Crocks (i-crystalizalizalizality kwi-wels, i-creections cracks kumda wobushushu)
Imvakalelo yokuphathwa kwe-thermal ikakhulu ixhomekeke kubume bemichiza, umbutho kunye nokusebenza kwento. I-NI kulula ukwenza imijikelezo yendawo ephantsi yokuphosa okanye i-ethectic enezinto ezingcolileyo ezifana ne-S kunye no-P. I-WOLD kulula ukwenza i-Coumbel Crystal yekristali ye-Crystal ye-corstal yesalathiso esomeleleyo, elungele ukwahlukana kokungcola okuyingozi kunye nezinto. Oku kukhuthaza ukwenziwa kwefilimu engapheliyo yefilimu kwaye iphucula ubuntununtunu bokuqhekeka kobushushu. Ukuba i-welding ayinabushushu ngendlela efanayo, kulula ukwenza uxinzelelo olukhulu kwaye lukhuthaze isizukulwane sobushushu obutshisayo.
Amanyathelo okuthintela:
a. Ngokungqongqo ulawule umxholo wokungcola okwenzakalisayo s kunye p.
b. Lungisa ubume bentsimbi ye-weld. Isakhiwo sesibini isigaba seld sinengxaki yokuqhekeka. Isigaba se-delta kwi-WORD sinokuphucula iinkolelo, sisuse ulwahlulo lwenqanaba lokungcola elinobungozi kumda wengqolowa, kwaye isigaba se-Delta singayinciphisa ifilimu yolwelo-mali.
c. Lungisa indawo yentsimbi ye-weld. Ngokufanelekileyo ukonyusa umxholo we-MN, c, kunye no-N kwintsimbi ye-austetitic yenqanaba elinye, kwaye wongeze inani elincinci le-riece, i-pickaxe, kunye ne-tenalm (enokunciphisa umda wobuchule bokuphawula ubuqhetseba.
d. Iindlela zenkqubo. Nciphisa ukugqithisa iphuli ye-molten ukunqanda ukwenziwa kweekristali zekristale. Sebenzisa igalelo elincinci lobushushu kunye necandelo elincinci le-suplds.
Umzekelo, intsimbi ye-Austetitic ye-Austetitic ixhaphakile kwii-rockings ezimnandi. Kuyenzeka ukuba ubeke umda ngokungqongqo umxholo we-infwoce kunye nobungakanani beenkozo zezinto ezisisiseko, zamkela iindlela ze-Wight Elftity ezixineneyo, igalelo elincinci lobushushu kunye nokunyusa umgangatho wokupholisa amajoyina.
I-4. Ubume bendawo yokuhlala ye-weldid
Ubushushu-amandla kufuneka uqinisekise ukuba iprimple yamalungu angama-weldied ukunqanda ukhuseleko lobushushu obuphezulu; Iqondo lokushisa eliphantsi kufuneka libe nobushushu obuphantsi kakhulu ukukhusela ubushushu obungaphantsi kobushushu obuqhetseba.
I-5. I-therting enkulu ye-welding
Ngenxa yokuphumelela okuphantsi kunye nokwandiswa okukhulu okulandelelanayo, ukungcungcutheka kwe-welding kuphakame, kwaye i-clamps ingasetyenziselwa ukuthintela ukungcungcuthekiswa.
Ukuba unayo iingxaki ezichazwe apha ngasentla, unokuyihlalutya le nto ngokujonga inkqubo ye-welding ye-pipe. Emva koko thatha amanyathelo ahambelanayo ukusombulula ingxaki ngokwemeko efanayo. Ukongeza kumxholo wezinto ezibonakalayo zezinto ezenziwayo, ukubumba kwee-arches, i-welding okwangoku, kunye nesantya se-welding seyunithi ye-weldied siya kuba nefuthe elithile kumgangatho we-welding. Njenge Umenzi wobungcali we-Weldimed Shiped Pedled Peped Izixhobo , wamkelekile ukunxibelelana I-Hingao Tech malunga neengxaki odibana nazo ekuveliseni imibhobho ye-austeditic, kwaye ujonge ukwenza inkqubela phambili kuwe.
