Umzi-mveliso wentsimbi yokuvelisa umzila kaloliwe wesitayile-eli binzana lihlala lihlala kwiincwadi zokuthenga, iinkcukacha zobunjineli, kunye nophicotho-zincwadi lwe-OEM. Kodwa yintoni efunwa ngabathengi *enyanisweni* xa bechaza iileyili zesikhokelo kwiintambo eziqhubekayo zokuntywila ezishushu? Hayi iincwadana ezimenyezelayo. Ayingomabango angacacanga malunga "nomgangatho ophezulu." Badinga iileyili ezisinda kwi-24/7 yebhayisekile eshushu, ukumelana ne-zinc slag abrasion, igcine i-±0.15 mm ethe tye ngaphezu kwe-8-meter spans, kwaye igcine uzinzo lwe-dimensional emva kwe-50,000+ ye-strip entry / exit tension. Leyo yinyani yokusebenza-kungekhona isihloko sokuthengisa.
Kutheni oololiwe beSikhokelo besilela-Ngaphambi kokuba bafake
Siye sabona izizathu ezithathu eziphindaphindayo kwiingcambu ze-12 ze-galvanizing line retrofits e-China, eJamani, naseMexico: okokuqala, ukungahambelani kwe-coefficients yokwandisa i-thermal phakathi komzimba kaloliwe kunye nesiseko sokunyuka; okwesibini, ukungonelanga kokuqina komphezulu (HV ≥420 efunekayo kumda wokusebenza, hayi nje ubuninzi); okwesithathu, i-microstructure engalinganiyo ukusuka kumazinga okupholisa angahambelaniyo. Umxhasi omnye watshintsha iileyili rhoqo emva kweentsuku ezingama-47-sade safaka imephu yeprofayili ye-thermal gradient yomgca wabo kwaye sayila ngokutsha umzila kaloliwe wejometri ukuze unciphise ukuhanjiswa kobushushu ukusuka kwiindawo ezithwele umthwalo. Iseti entsha yahlala iinyanga ezili-14. Ukuchaneka akugqitywanga-kubhakwa ekukhethweni kwe-alloy, ukuphosa indlela yokuqinisa, kunye nokunciphisa uxinzelelo lwasemva kokushisa.
Ukukhetha izinto eziphathekayo akukhethi-Sisigqibo soBunjineli bokuqala
I-Q235 eqhelekileyo okanye i-ASTM A572 yeBanga le-50 yensimbi ayiyi kunqumla. Amaqondo obushushu ebhafu eZinc abaleka kuma-450–465°C. Izantya zentambo zidlula kwi-180 m/min. Uxinzelelo loqhagamshelwano lubetha i-1.2 MPa kwizikhokelo zokungena. Udinga inkqubo yemathiriyeli eyenzelwe lo ntathu: ukuxhathisa ukudinwa kwe-thermal, ukuxhathisa i-galling ngokuchasene ne-zinc etyhidiweyo, kunye nozinzo lokuhamba phantsi komthwalo ogobayo oqhubekayo. Kungenxa yoko le nto i-AMS 5387 i-cobalt alloy ibonakala ngokuphindaphindiweyo kwi-high-reliability ye-high-reliability ye-rail applications-kwaye kutheni i-T800-based based variants ihambisa iinzuzo ezinokulinganiswa kubomi bokugqoka apho ukuqokelela kwe-zinc slag kunzima. Siqinisekisa yonke ibhetshi nge-spark emission spectroscopy kunye ne-metallographic cross-sections-hayi nje iingxelo zokuxinwa. Ukuba umthengisi wakho uthumela ngaphandle kobungakanani bengqolowa (ASTM E112) kunye nedatha yokusabalalisa i-carbide, buza ukuba kutheni.
Ulawulo Lokuvelisa Lumisela uMsebenzi woMmandla
Imizila yesikhokelo ibonakala ilula. Akunjalo. I-taper eyi-0.3 mm ngaphezu kweemitha ezi-6 itshintsha ukulandelwa komcu. Ukwahluka kwe-0.08 mm kubude bomzila kaloliwe kwiindawo ezine zokunyuka kubangela iziphene zokwaleka ezibangelwa kukungcangcazela. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sihambisa iileyili zoomatshini kwiseti enye-akukho kuphinda-phinda kuqhutyelwe-kumaziko e-CNC e-5-axis kunye nembuyekezo yexesha langempela le-thermal. Sibaphose kwiimolds zotyalo-mali olulawulwayo, hayi isanti evulekileyo. Siqinisekisa ngokuthe ngqo nge-laser interferometry, hayi i-straightedges. Kwaye silandelela wonke uloliwe kwindawo yawo yobushushu, umhla wokugalela, inguqulelo yenkqubo yomatshini, kunye nengxelo yokugqibela yeCMM. Oku akukho overkill. Yindlela osusa ngayo "ukungaphumeleli okufihlakeleyo" okuxabisa i-$ 28,000 / iyure ngexesha lokuphumla elingacwangciswanga.
- CNC oomatshini iindawo: Ulungelelwaniso olupheleleyo lweeprofayili zikaloliwe-kubandakanya ii-chamfers zokungena eziguqukayo kunye neetshaneli zokupholisa ezidibeneyo
- Amacandelo e-cobalt-nickel alloy: I-AMS 5387 kunye ne-T800 amabakala, isisombululo-enziwe kwaye sidala ngokwe-AMS 2750E
- Ukuphoswa kwentsimbi: Intsimbi ye-Nodular EN-GJS-600-3 kunye nokubalwa kwamaqhuqhuva egraphite eyongeziweyo yokumanzisa
- Iintsimbi zentsimbi kunye neentsimbi ezingenasici: I-AISI 4140 kunye ne-17-4PH, iphathwa ngubushushu ukuya kwi-HRC 38-42 kwiindawo zokunxiba
Indawo yethu ethobela i-ISO idibanisa ukuphosa, ukwenza oomatshini, kunye nokugqiba phantsi kophahla olunye-ukuze ukugqwethwa kwe-thermal ukusuka ekucimeni akunyanzeli ukuphinda kusebenze kwiireyile ezigqityiweyo. Asikhupheli ngaphandle iinkqubo ezingundoqo. Olo lawulo oluthe nkqo luthetha ukuba sihlengahlengisa amazinga okutya phakathi kwe-machining ukuba i-CMM ibona ukuphambuka kwe-0.012 mm-kwaye siyenza ngaphambi kokuba inxalenye ishiye i-spindle.
Ukukhetha iSikhokelo soMveliso weNtsimbi yeGalvanized Rails Factory sithetha ukubuza imibuzo enzima
Abanye banokuphikisa ukuba nayiphi na isiseko esichanekileyo sinokwenza la malungu. Nangona kunjalo, iileyili zomgca we-galvanizing zifuna ulwazi oluthe ngqo lwesizinda: indlela i-zinc oxide buildup ekuchaphazela ngayo ukuhanjiswa kwe-thermal, indlela i-strip flutter etshintsha ngayo i-angle dynamics, indlela i-chemistry yokuhlambela ezitshintsha ngayo iindlela zokubola kukaloliwe. Iivenkile zoomatshini beGeneric azinayo loo meko. Xa kuvavanywa a galvanized steel production line guide rails factory, bagxininise ekuboneni: iifoto zangempela zemveliso yeereyili ezifakwe kwimigca ephilayo, iingxelo ze-metallurgical kwiibhetshi ezintathu zokugqibela, kunye nokuqinisekiswa kwe-GD & T yeedatum ezibalulekileyo-kungekhona nje imizobo. Buza indlela abaphatha ngayo ukulungiswa kwe-weld kwiintsimbi ezityhidiweyo (i-spoiler: asibavumeli-siyayilahla kwaye siyibuyisela kwakhona). Cela idatha yovavanyo kwi-coefficient yokhuhlane ngokuchasene nobukhulu be-zinc slag. Emva koko thelekisa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzela abathengi behlabathi kuba siphatha iintsimbi zesikhokelo njengeenkqubo ezisebenzayo-hayi izinto ezimile. Sisebenzisana nenjineli kunye nezihlanganisi zemigca kwisithuba serola, iimfuno zetorque, kunye nokudityaniswa kokhuselo lobushushu. Sithumela iileyili ezineebhloko zereferensi ezilinganisiweyo zokuqinisekisa indawo. Sibhala zonke izigqibo-ukusuka kwingqiqo yokukhetha i-alloy ukuya kwi-fixture design notes-kwiphakheji ye-PPAP. Ngenxa yokuba kwi-galvanizing, ukuthembeka akulinganiswa kwiinyanga. Ilinganiselwa kwii-microns zokunxiba kwisigidi seemitha zomcu ocutshungulweyo.
Ukuba iileyili zakho zesikhokelo zangoku zifuna uhlengahlengiso lonke utshintsho-okanye ukuba ukufana kwakho kwengubo kuchaphazeleka kufutshane neendawo zokungena / zokuphuma-awujongani nomba wokulungisa. Ujongene nemathiriyeli kunye nesithuba sokuchaza inkqubo. Ukuyivala kuqala ngomzi-mveliso oqonda i-zinc, kungekhona nje intsimbi.
