Ngaba uyazi ngenene malunga ne-flux?

-FLUX-

Fluxyimathiriyeli ye-granular welding.Ngexesha le-welding, inokuncibilika ukwenza i-slag kunye negesi, edlala indima yokukhusela kunye ne-metallurgical kwi-pool etyhidiweyo.

Umgaqo-siseko

I-Flux yenziwe nge-marble, i-quartz, i-fluorite kunye nezinye i-ores kunye ne-titanium dioxide, i-cellulose kunye nezinye iikhemikhali.I-Flux isetyenziselwa ukuwelda i-arc emanzini kunye ne-electroslag welding.Xa isetyenziselwa ukuwelda zonke iintlobo zentsimbi kunye neentsimbi ezingezizo, kufuneka kusetyenziswe ngokufanelekileyo kunye nocingo oluhambelanayo lwe-welding ukuze ufumane i-weld eyanelisayo.

Ukuhlelwa

Zininzi iindlela zokuhlela zokuguquguquka, ngokusetyenziswa, indlela yokuvelisa, ukwakheka kweekhemikhali, ukuwelda kunye nepropathi yentsimbi yolwahlulo, kodwa kwakhona ngokwe pH yokuguquguquka, ulwahlulo lwe-flux granularity.Kungakhathaliseki ukuba luhlobo luni lwendlela yokwahlula, bonisa kuphela iimpawu ze-flux ukusuka kwinkalo ethile, ayinakubandakanya zonke iimpawu ze-flux.Iindlela zokuhlela ezidla ngokusetyenziswa zezi:

1. Ukuhamba phakathi

I-flux engathathi hlangothi ibhekisela kwi-flux engatshintshi kakhulu ukubunjwa kweekhemikhali zetsimbi edibeneyo kunye nokwakheka kweekhemikhali zocingo lwe-welding emva kwe-welding.I-flux engathathi hlangothi isetyenziselwa i-welding ye-multi-pass welding, ngakumbi kwi-welding yesiseko sesinyithi esinobunzima obukhulu kuno-25mm.

a.I-flux ayiqulathanga i-SiO2, i-MnO, i-FeO kunye nezinye i-oxides.

b.I-Flux ayinayo impembelelo ye-oxidation kwintsimbi ye-weld ngokusisiseko.

c.Xa udibanisa isiseko sesinyithi kunye ne-oxidation enzima, iipores kunye ne-weld cracks ziya kuveliswa.

2. Ukuguquguquka okusebenzayo

I-flux esebenzayo ibhekisela ekongezweni kwexabiso elincinci le-Mn, Si deoxidizer flux.Inokuphucula ukuchasana ne-porosity kunye nokuqhekeka.I-flux esebenzayo inezi mpawu zilandelayo:

a.Ngenxa ye-deoxidizer, uMn kunye noSi kwintsimbi etyhidiweyo iya kutshintsha nge-arc voltage.Ukunyuka kweMn kunye neSi kuya kwandisa amandla esinyithi esityhidiweyo kunye nokunciphisa ukuqina kwempembelelo.Ke ngoko, i-arc voltage kufuneka ilawulwe ngokungqongqo xa i-multi-pass pass welding.

b.I-flux esebenzayo inokumelana ne-porosity eyomeleleyo.

3. I-alloy flux

I-alloy flux yongeza amacandelo amaninzi e-alloy ekutshintsheni kwezinto ezixutywayo, uninzi lwe-alloying flux yi-sintered flux.I-alloy flux isetyenziselwa ikakhulu ukuwelda kwentsimbi ephantsi yealloy kunye ne-surfacing engagugiyo.

4. Ukunyibilika okuguquguqukayo

I-Melt flux yimathiriyeli ekrwada yeeminerali ezahlukahlukeneyo ezixutywe ngokuhambelana nomlinganiselo onikiweyo, zifudunyezwe kwii-degrees ezingaphezu kwe-1300, zinyibilike kwaye zixutywe ngokulinganayo, emva koko zipholile emanzini ukuze zibe yigranulate.Emva kokumisa, ukugaya, ukuhlolwa, ukusetyenziswa kokupakisha.

I-brand ye-melting flux yasekhaya ibonakaliswa ngu-"HJ".Idijithi yokuqala emva kokuba ibonise umxholo we-MnO, idijithi yesibini ibonisa umxholo weSiO2 kunye neCaF2, kwaye idijithi yesithathu ibonisa iimpawu ezahlukeneyo zohlobo olufanayo lwe-flux.

5. Sintering flux

Yomile ixutywe ngokomlinganiselo onikiweyo wezithako, kwaye emva koko wongeza i-binder (iglasi yamanzi) yokuxuba okumanzi, kwaye emva koko i-granulation, kwaye emva koko ithunyelwe kwisithando somlilo sokunyanga, ukomisa, kwaye ekugqibeleni sifakwe malunga nama-500 degrees.

I-brand ye-sintered flux yasekhaya imelwe yi "SJ", idijithi yokuqala emva koko imele inkqubo ye-slag, kwaye idijithi yesibini neyesithathu ibonisa iimpawu ezahlukeneyo zenkqubo ye-slag efanayo.
