Iplate yensimbi

Yintsimbi yeflethi ekhutshelwe intsimbi ye-molten kwaye icinezelwe emva kokupholisa.
Yinto ethe tyaba, uxande kwaye ungaqengqeleka ngokuthe ngqo okanye unqunywe kwimigca yentsimbi ebanzi.
Iplate yensimbi yahlulwe ngokobunzima, iplate ecekeceke ingaphantsi kwe-4 mm (i-stanenel yi-0.2 mm), ipleyiti yentsimbi ephakathi yi-4-60 mm i-60-16 mm.
Amaphepha ensimbi ahlulahlulwe ukuba avuthiwe kwaye aqengqeleka ngokuqengqeleka ngokuqengqeleka.
Ububanzi beplate emdaka yi-500 ~ 1500 mm; Ububanzi bephepha elinzima yi-600 ~ 3000 mm. Amashiti ahlelwa luhlobo lwentsimbi, kubandakanya intsimbi eqhelekileyo, intsimbi esemgangathweni, intsimbi esemthonjeni, intsimbi yasentwasahlobo, intsimbi engenasitayile, intsimbi engekho mthethweni, intsimbi yentsimbi ecocekileyo, njl.; Iplate ye-enamel, ipleyiti ye-bullet, njl.
Intsimbi yesakhiwo esisezantsi
(Ikwabizwa ngokuba yintsimbi eqhelekileyo ye-alloy, HSLA)
1. Injongo
Isetyenziselwa ikakhulu ekwenzeni iibhulorho, iinqanawa, izithuthi, iinqanawa zoxinzelelo lweoyile, imibhobho yegesi, i-gesi enkulu, njl.
2. Iimfuneko zomsebenzi
(1) Amandla aphezulu: Ngokubanzi amandla ayo asisivuno ingaphezulu kwe-300MPA.
. Kwizinto ezinkulu ze-weldied, ubunzima obuphezulu bukwafuneka.
(3) Intsebenzo elungileyo ye-welding kunye nokusebenza okubandayo.
(4) Ubushushu benguqu ebandayo.
(5) Ukunganyangeki kakuhle.
3. Iimpawu zethanga
.
(2) Yongeza izinto ezisekwe kwiManganese.
.
Ukongeza, ukongeza isixa esincinci sobhedu (≤0.4%) kunye ne-phosphorus (malunga ne-0.1%) inokuphucula ukumelana nokunganyangeki. Ukongeza inani elincinci lezinto ezinqabileyo zomhlaba kunokubangela i-gestas, hlambulula intsimbi, kunye nokuphucula ubuchule kunye nenkqubo yokusebenza.
4. Ihlala isetyenziswa intsimbi yesakhiwo esezantsi
I-16mn yeyona ndlela isetyenziswa kakhulu kwaye inodidi oluphambili lwensimbi ye-Alloty ephantsi ezweni. Isakhiwo esisetyenzisiweyo sisimo se-ferrite ye-ferite-pearlite, kwaye amandla ayo amalunga nama-20% ukuya kwi-30% ngaphezulu kwe-qrbon q235, kunye ne-themosion yohlobo lwe-quarbon q2% ukuya kwi-38% ephezulu ephezulu.
I-15mnvn yeyona ntsimbi isetyenziswa intsimbi kumandla aphakathi. Inamandla aphezulu, kunye nokuba nobuhle, ubushushu obunobushushu obuphantsi ubushushu, kwaye busetyenziswa kakhulu ekwenzeni izinto ezinkulu ezinjengeebhulorho, abongikazi kunye neenqanawa.
Emva kokuba amandla angaphezulu kwe-500mpa, i-Ferrite kunye nezakhiwo zePearlilo kunzima ukufezekisa iimfuno, ke i-cainen yekhabhoni ye-cainatic iphuhlisiwe. Ukongezwa kweCR, MON, MN, b kunye nezinye izinto ziluncedo ukufumana isakhiwo se-Biain Play, ukuze amandla aphezulu, kwaye uninzi lwe-welding kunye nolona luhlobo luphezulu , Iinqanawa zoxinzelelo oluphezulu, njl.
5. Iimpawu zonyango lobushushu
Olu hlobo lwensimbi lusetyenziswa ngokubanzi kwindawo epholileyo eshushu kwaye yomoya kwaye ayifuni unyango olukhethekileyo lobushushu. ULWAZI LWEZOBUCHULE NGOKUSETYENZISIWEYO NGOKUGQIBILEYO + SORRBIte.
Intsimbi ye-allous
1. Injongo
Isetyenziswa ikakhulu ekwenzeni i-gears yothumelo kwiimoto kunye neetrektara, iipisi, iipiston, kunye namanye amalungu omatshini kwiinjini zangaphakathi. Amacandelo anjalo athwaxwa yingxabano eqinileyo kwaye anxibe ngexesha lomsebenzi, kwaye kwangaxeshanye athwale imithwalo enkulu yokutshintsha, ngakumbi imithwalo yempembelelo.
2. Iimfuneko zomsebenzi
.
(2) Isiseko sinobukrakra obuphakathi kunye namandla aphezulu ngokwaneleyo. Xa ubunzima be-core awonelanga, kulula ukwahlukana phantsi kwesenzo somthwalo wempembelelo okanye ngaphezulu; Xa amandla awonelanga, umaleko we-brittle odrett waphulwe ngokulula kwaye waphoswa.
.
3. Iimpawu zethanga
.
(2) Yongeza ulwabiwo lwezinto ukuphucula ukuba nzima: CR, Ni, Mn, B, njl. Zihlala zongezwa.
.
I-4. Ibanga lentsimbi kunye neBanga
I-20CKRCRCRCR SORTATION ALTEATRES STEE. Olu hlobo lwensimbi lunokukhanya okusezantsi kunye namandla aphantsi.
I-20cMTINI PREAMIUM YOKUGQIBELA I-AFECY STEE. Olu hlobo lwensimbi lunolwazi oluphezulu, imvakalelo ephantsi kakhulu, i-iyunifomu ye-cariction ye-carbring, kunye nezomatshini ezilungileyo zezobuchwephesha kunye nezobugcisa.
I-18Ch2Ni4wa kunye ne-20ccr2ni4a Altmes Allobiation Allofied. Olu hlobo lwensimbi luqukethe izinto ezifana neCR kunye ne-NI, lunolwazi oluphezulu, kwaye lunobunzima obulungileyo kunye nobushushu obuphantsi.
I-5. Ukugcina unyango kunye neepropathi zoLoftware
Inkqubo yonyango lobushushu yensimbi ye-Alloty ye-Alloty icingela ngokuthe ngqo emva kokudibana, kwaye emva koko ukuhendwa kubushushu obuphantsi. Emva konyango lobushushu, ubume be-subled ye-carburty yisamente ye-ALTECY yi-marticicite + isixa esincinci se-austensite, kwaye ubunzima yi-60HRC ~ 62HRC. Isakhiwo esiyintloko sihambelana nokukhubeka kwentsimbi kunye nobungakanani becandelo lamacandelo. Xa yayinzima kakhulu, i-carbon enomsindo ophantsi ngobuqili be-40 hrc ukuya kwi-48HRC; Kwiimeko ezininzi, kungumntu ovuthayo, uvutha ngumsindo kunye nenani elincinci lesinyithi. Umzimba wezinto, ubunzima yi-25hrc ~ 40HRC. Ubunzima bentliziyo buhlala bungaphezulu kwe-700KJ / m2.
I-alloy ecinywe kwaye ivutha ngumsindo
1. Injongo
Intsimbi ecinywe kwaye inomvuzo osetyenzisiweyo kusetyenziswa ngokubanzi ekwenzeni amacandelo ahlukeneyo kwiimoto, iitrektara, izixhobo zoomatshini, ii-shaft, iintambo, njl.
2. Iimfuneko zomsebenzi
Uninzi lwamalungu acinywe kunye nomphunga oxineneyo abonisa imithwalo eyahlukeneyo, imeko yoxinzelelo inzima, kwaye imitshini iphakamileyo kwaye inamandla aphezulu ezisebenzayo, oko kukuthi, amandla aphezulu kunye nobunzima. Intsimbi ecinywe kunye nentsimbi evuthayo nayo ikwafuna ukuba noxinzelelo olufanelekileyo. Nangona kunjalo, iimeko zoxinzelelo zamalungu ahlukeneyo zahlukile, kwaye iimfuno zokulukhumbula zihlukile.
3. Iimpawu zethanga
(1) Ikhabhoni ephakathi: Umxholo wekhabhoni ngokubanzi phakathi kwe-0.25% kwaye i-0.50%, nge-0.4% kwisininzi;
. Umzekelo, ukwenziwa kwentsebenzo ye-40 yentsimbi emva kokucinywa kunye nokunyanga umlinganiso kuphakamile kune-45 yentsimbi;
. Ukongeza i-MO kunye ne-W kwintsimbi inokuthintela uhlobo lwesibini lohlobo lobushushu, kwaye umxholo wayo ofanelekileyo malunga ne-0.15% ye-0,5.30% mo okanye i-0.8.2% W.
Thelekisa iipropathi ze-45 yentsimbi kunye ne-40cr yentsimbi emva kokucingela kunye nokucaphuka
Ibanga lensimbi ye-SEE kunye nonyango lobushushu
I-45 yentsimbi 850 ℃ Ukucinywa kwamanzi, i-550 ℃ I-F50 700 500 15 45 700
I-40 ye-850 ℃ Ukuhamba kweoyile, i-570 ℃ i-F50 (Core) 850 670 16 58 1000
I-4. Ibanga lentsimbi kunye neBanga
.
. Ukongezwa kweMolybdenum ayinakuphucula ukuqina, kodwa kukhusela uhlobo lwesibini lohlobo lobugcisa.
. Ukongeza i-molybdenum efanelekileyo ukuya kwi-chromium-nikel yensimbi ayisiyohlazo olulungileyo, kodwa iluphelise uhlobo lwesibini lolwalamano.
I-5. Ukugcina unyango kunye neepropathi zoLoftware
Unyango lokugqibela lobushushu lwe-Alloty kwaye inyibilikisi evuthiweyo iyacima kunye nobushushu obungaphezulu komsindo (ukucutha kunye nokucaphuka). I-Allow eqingqiweyo kunye nentsimbi evuthayo inolwazi oluphezulu, kwaye ioyile isetyenziswa ngokubanzi. Xa ubunzima bungakumbi, kunokuba njalo-moya, okunokunciphisa isiphene sonyango lobushushu.
Ipropathi yokugqibela ye-Alloty ecinywe kwaye inomvuzo ovuthiweyo uxhomekeke kubushushu beqondo lomtshato. Ngokubanzi, ukuliphakamisa ngama-500 ℃ -650 ℃ isetyenziswa. Ngokukhetha ubushushu bomlinganiso, ipropathi efunekayo inokufumaneka. Ukwenzela ukuthintela uhlobo lwesibini lwe-Cherter, ukupholisa ngokukhawuleza (ukupholisa amanzi okanye ukupholisa ioyile) emva kokuba umlinganiso kuyingenelo ekuphuculeni ubunzima.
ULWAZI LWE-LALTY LE-ALTEY STEECY NOPHANDO LOKUQHUTYELWA NGEXESHA LOKUGQIBELA Unyango lwe-Sorbin Amalungu afuna ukudinwa kweendawo zokunganyangeki (ezinjengeegiya kunye nee-Spindles), ukufudumeza ukufudumeza ukufudumeza kunye nokwakhiwa kobushushu obuphantsi kwenziwa, kwaye umphezulu wobushushu uvutha umlilo. Ubunzima bomphezulu bunokufikelela kwi-55HRC ~ 58HRC.
Ilifin elinesivuno sentsimbi ecinywe kwaye ivutha ngumsindo emva kokucinywa kwaye ukuwatshata okumalunga ne-800pa, kunye nobunzima bempembelelo yi-800kj / M2, kwaye ubunzima be-CRECY NOKUFUNDA I-22HRC ~ 25HRC. Ukuba ubungakanani becandelo elingumnqamlezo bukhulu kwaye abunzima, ukusebenza kuncitshisiwe kakhulu.
