I-Manganese ye-Manganese ye-Manganese ye-Manganese emva konyango lwamanzi anzima, ubukhali bokuqala buphantsi, yintoni unobangela wemagnetic?

I-Manganese Steen Steel Refings ihlala inobuqili bokuqala ngaphantsi kune-Brinell 180 emva konyango olunzima lwamanzi, kwaye kunokubakho i-fanomenon ye-manetimetion xa ikhutshwe ziimagnethi. Ke sithini isizathu soku? Ngaba oku kunefuthe kumgangatho wokuphoxeka? Singayicombulula njani le ngxaki kwimveliso.

Sisiphi esona sizathu sobuqili bokuqala kunye ne-manganetism yentsimbi ephezulu yentsimbi emva konyango olunzima lwamanzi? Ungaphucuka njani? I-Manganese yensimbi ye-manganese inobuqili obuncinci kunye ne-magnetism emva kokunyangwa kwamanzi, ikakhulu ngenxa yeenkqubo zonyango ezingalunganga okanye ezixhamlayo. Izizathu ezizodwa zezi zilandelayo:

Imicimbi yeNkqubo yoNyango

I-1. Ubushushu obungapheliyo okanye ixesha elifutshane lokuthatha

Amanzi athatyathwa gadalala kwintsimbi ephezulu ye-manganese (enje nge-ZGMN13) ifuna ukufudumeza kwi-1050-1100 ℃ ukuwuchitha i-carbledes kwi-Austedede. Ukuba iqondo lobushushu alwanelanga okanye ukubamba ixesha alonelanga, i-carbides ayichithwanga ngokupheleleyo, eyakukhokelela kumxholo wekhabhoni ophantsi kwi-Austerix Matrix, kwaye i-Harbides ePhezulu inokuthi ibe ngumqobo wexabiso elincinci le-FERBIT, evelisa i-maynetism.

I-2. Isantya esipholileyo sokupholisa

Emva kokufudumeza, ukuphola kwamanzi ngokukhawuleza kuyadingeka (ubushushu bamanzi ≤ 30 ℃). Ukuba inqanaba lokupholisa liyacotha (njengokungapheleli kwamanzi angonelanga), ukuqiqa okukhulu kwamanzi), i-Austerite inokwenza i-carbides okanye iguqule kwi-martite okanye ifestile, ikhokelela ekunciphiseni kobunzima kunye neepropathi zemagazini.

Ukuphambuka kwamachiza

1. Umxholo wekhabhoni ophantsi

Umxholo we-carbon wensimbi ephezulu ye-manganese ihlala phakathi kwe-0.9% kunye ne-1.4%, kwaye ikharbon yindawo ephambili ekugcineni uzinzo lwe-austedite. Ukuba umxholo we-carbon usemgangathweni (onje nge <0.9%), uzinzo lwe-austerite luyancipha, kwaye i-Ferrite icinezelwe ngokulula emva kokuphathwa gadalala kwamanzi, kukhokelela kubunzima obungonelanga.

I-2. I-manganese ye-manganese okanye impembelelo kwezinye izinto

Umxholo we-manganese kufuneka ube ≥ 11% (njenge-ZGMN13 equlethe i-11% ~ 14% manganese). Ukuba umxholo we-manganese usezantsi kakhulu, uzinzo lwencipha lokuphumelela kwaye ifestile iveliswa ngokulula; Ukongeza, umxholo we-silicon ogqithisileyo (> i-0.8%) inokukhuthaza i-Parbide Preciation kwaye ichaphazele uzinzo lwezicubu.

Isiphene sezicubu

I-1. I-carbides egqithisileyo

Ukuba inqanaba lokupholisa liyacotha kwaye ii-carbides eziphambili zibamba kwaye zingachithi gwenxa kunyango lwe-matrix, kwaye i-carbides eshiyekileyo iya kunciphisa ubunzima be-matrix, i-Augus ejikeleze i-carbiting, ikhokelela kwi-magnetism.

2. I-Coarde Austerite

Ukufudumeza kubushushu obuphezulu kakhulu okanye ukubamba ixesha elide kunokukhokelela ekuthinteleni iingqolowa ze-austedite, ukucaciswa ngokulula kwe-carbides okanye ukwakheka kwe-carlite kwimida yengqolowa, echaphazela ubunzima kunye nobugqwirha.

Ezinye izinto

Ubuninzi obungalinganiyo bobubanzi beinkcazelo: Inqanaba lokupholisa elicothayo kwiindawo ezinzima, ezinokwenza lula izakhiwo ezingalunganga;

Umcimbi osemgangathweni wamanzi: Umgangatho wamanzi ahluphekayo (njengokungcola kwamanzi) ngexesha lokupholisa amanzi kunciphisa ukusebenza ngokukuko kunye nokukhokelela kwinguqu ye-tissument engapheliyo.

Amanyathelo esisombululo

1. Yandisa inkqubo yonyango lobushushu: Qinisekisa ubushushu bokufudumeza (i-1050-1100 ℃) kunye nexesha le-imeyile (i-25mm), kwaye usebenzise amanzi awongezelelekileyo aneleyo;

2. Ukulawulwa kweekhemikhali

3. Yenza amanzi athambileyo

4. Ukuphuculwa kwenkqubo: Ukulawula ubushushu obugadayo kunye nenqanaba lokupholisa ukunciphisa ukwenziwa kweecarbides eziphambili.

Ukuba ingxaki iyaqhubeka, kuyacetyiswa ukuba kuvavanye ubume bekhemikhali kunye nokwakhiwa kwezesinegraphic, kwaye kulungelelanise inkqubo ngokufanelekileyo.

Zithini iziphumo ze-magnetism kumgangatho wensimbi ye-manganese ephezulu ye-manganese enelukhuni yokuqala ephantsi emva konyango olunzima lwamanzi? High manganese steel castings have low hardness (

Ukwehla okufanelekileyo kwiipropathi zoomatshini

1. Eyona nto incitshisiweyo yokunxiba

Ukuxhaphaza intsimbi ephezulu ye-manganese ixhomekeke kuhlobo lwe-austenite eguqula kwi-Marteyini phantsi komthwalo wempembelelo. Ukuba kukho isixa esikhulu se-Ferrite okanye i-carbider entsalela okanye intshabalalo engapheliyo, kwaye iguquko le-AUSTELINIT alinalo impembelelo phantsi kwempembelelo, kwaye ireyithi yexabiso iya kunyuka kakhulu (umzekelo, xa i-CRUSE inqanyulwe ngaphezulu kwe-50%).

2. Amandla aneleyo kunye nobunzima

Ubukho be-ferrite kunye ne-carbides inokuqhekeza i-Austerix Matrix, ikhokelela ekuncipheni kwamandla e-thenste (≥ 1485MPA), kunye nokuqhekezwa kwefuthe (njengamazinyo e-escavavator).

Ukonakaliswa kokunganyangeki kunye nokuchasana kwe-oxidation

I-electrode i-Ferrite iphantsi kune-austedite, kwaye kuqhelekile ukwenza iiseli ezincinci kwimithombo yeendaba yezixhobo, ukukhawulezisa i-morrosion (njengokuthambisa i-acidic sutorry);

Unxibelelwano phakathi kwe-carbider yentsalela kunye ne-matrix ithathelwa ukuba ibe yindawo yokuqala ye-oxidation, kwaye umthamo we-antioxidant uncipha kumaqondo obushushu aphezulu (anjengama-300 ℃), ekhokelela ekumiselweni kwe-ox of theide oxineneyo.

Iingozi zokhuseleko ezinokubakho ngexesha lokusetyenziswa

1. Iingxaki zendibano ezibangelwa yi-magnetism

I-Magnetic Refirings inokuvuma ukungcola ezinjengeefilimu zentsimbi, enokuchaphazela ukuchaneka komsebenzi okanye ukubangela ukujongela phantsi kwendibano yokulungisa imilenze), kwaye kukhokelela ekungaphumlweni kwezimbiwa.

2. Ukungaphumeleli komngcipheko phantsi kwemithwalo enamandla

Ukuba amacandelo asetyenziselwa ukumelana nefuthe, njengokubuya kukaloliwe, anokukhokelela kuxinzelelo loxinzelelo, olunokubangela ukusasazeka kwexeshana kunye nokwandisa umngcipheko wesiquphe.

4. Ukunyuka kweendleko zolungiso olulandelayo kunye nolondolozo

Ukulahla ubunzima obungonelanga akunakusetyenziswa ngokuthe ngqo kwaye kufuna ukuba kufuna amanzi athambileyo amanzi, owonyusa ukusetyenziswa kwamandla kunye neendleko zezabasebenzi zonyango;

Ukuba iziphene zombutho ziqatha (njengenani elikhulu le-carbides), ukuphatha okwesibini kusenokungakwazi ukulungisa ngokupheleleyo kwaye kungancipha, kukhokelela kwinkunkuma yempahla.

shwankathela

Intsebenzo ephambili yentsimbi ephezulu ye-manganese ilele kwi "Austenite enye". Ubunzima obuphantsi kunye ne-magnetisim baboniswa ngqo kulwakhiwo olugwenxa, oluya kubenza buthathaka ixabiso lokuphoxeka ngokwesikhundla sokunganyangeki, iipropathi zoomatshini, kunye nezinye iinkalo. Lawula ngokungqongqo inkqubo yobushushu yonyango kunye nokuqulunqwa kwemichiza ngexesha lemveliso ukuthintela ezo ngxaki.
