Habka gelinta foornada
Wakiilka Carburizing wuxuu ku habboon yahay dhalaalidda foornada induction, laakiin isticmaalka gaarka ah maaha mid la mid ah marka loo eego shuruudaha habka.
(1) Foornada inta jeer ee dhexdhexaadka ah ee dhalaalaysa iyadoo la adeegsanayo wakiilka carburizing, marka loo eego saamiga ama shuruudaha u dhigma kaarboonka oo leh walxaha lagu daro qaybta hoose ee foornada, heerka soo kabashada wuxuu gaari karaa in ka badan 95%;
(2) dhalaalidda birta dareeraha ah haddii qadarka kaarboonku aanu ku filnayn in lagu hagaajiyo wakhtiga kaarboonka, marka hore ciyaar foornada foornada, ka dibna ku dar wakiilka carburizing, iyada oo loo marayo kululaynta birta dareeraha ah, walaaqaya electromagnetic ama walaaqin macmal ah si ay u milmaan nuugista kaarboonka, heerka soo kabashada waxay noqon kartaa qiyaastii 90, haddii habka carburizing heerkulka hooseeya, taas oo ah, kharashka kaliya ayaa dhalaalinaya qayb ka mid ah heerkulka birta dhalaalaysa waa yar yahay, dhammaan wakiilka karbuunta mar lagu daro birta dareeraha ah, Isla mar ahaantaana, waxaa lagu cadaadiyaa dareeraha. bir leh lacag adag si ay uga ilaaliso dusha sare ee birta dareeraha ah. Habkani wuxuu kordhin karaa carburization birta dareeraha ah in ka badan 1.0%.
Isticmaalka saxda ah ee wakiilka carburizing ee foornada kicinta
1, isticmaalka 5T ama foorno koronto oo ka badan, alaabta ceeriin waa hal iyo xasilloon, waxaan kugula talineynaa habka isku-darka kala firdhiya. Marka loo eego shuruudaha kaarboonka, marka loo eego saamiga maaddooyinka, wakiilka carburizing iyo kharashka birta ee dufc kasta oo walxaha ah si ay ugu biiraan foornada qaybta hoose, lakabka birta ah ee dallacaadda lakabka carburizing, heerka nuugista carbon gaadhaan 90% -95%, wakiilka karbooriyaha ee dhalaalid ha ku dhejin, haddii kale way fududahay in lagu duubo qashinka qashinka, saameynaya nuugista kaarboonka;
2. Foornada soo noqnoqda ee soo noqnoqda dhexdhexaadka ah ee ku saabsan 3T ayaa la isticmaalaa, iyo alaabta ceeriin waa hal iyo xasilloon. Waxaan ku talinaynaa habka isku-darka dhexe. Marka wax yar oo birta dhalaalaysa la dhalaaliyo ama lagu dhex daayo foornada, waxa carburizing-ka lagu daraa dusha sare ee birta dhalaalaysa hal mar, birta ayaa isla markiiba lagu daraa. Wakaalattii karoora qabatamaa ta’uu danda’u, si’a ta’uu danda’a jedhameera lammiiwwan lammiiwwan adda addaa 90% ta’uu qaba;
3, isticmaalka foornada korantada ee dhexdhexaadka ah ee dhexdhexaadka ah, alaabta ceeriin leh birta doofaarka iyo walxaha kale ee kaarboonka sare leh, waxaan kugula talineynaa hagaajinta wakiilka carburizing. Ka dib dhalaalka birta/dharka birta, hagaajiso kaarboonka, waxaa lagu dari karaa dusha sare ee birta/ birta dhalaalaysa, iyada oo loo marayo walaaqda hadda jirta ee birta (birta) biyaha ama walaaqaya macmal ah si ay u milmaan una nuugaan alaabta, heerka nuugista kaarboonku waa qiyaastii 93%.
Habka carburization foornada dibadda
1. Ku buufi budada graphite gudaha bacda
Budada graphite sida walaxda carburizing, oo ku afuufaysa qadarka 40kg/t, ayaa laga filan karaa inay ka dhigto kaarboonka birta dareeraha ah 2% ilaa 3%. Marka maadada kaarboonka ee birta dareeraha ah ay si tartiib tartiib ah u korodhay, heerka isticmaalka kaarboonku wuu yaraaday. Heerkulka birta dareeraha ah ka hor carburization wuxuu ahaa 1600 ℃, celceliska heerkulka kaarburization ka dib wuxuu ahaa 1299 ℃. Carburization budada Graphite, guud ahaan isticmaalaya nitrogen sida side, laakiin xaaladaha wax soo saarka warshadaha, hawada cadaadisku waa ku haboon yahay, iyo ogsijiinta ee gubashada hawada cadaadisay si ay u soo saaraan CO, kulaylka falcelinta kiimikada magdhabi kara qayb ka mid ah heerkulka hoos u dhaca, iyo CO dhimista jawiga. waxay ku haboon tahay hagaajinta saameynta carburization.
2, isticmaalka birta carburizing agent
100-300 graphite budada carburizing wakiilka waxaa lagu dhejin karaa xirmada, ama laga bilaabo saxanka birta ee qulqulka, ka dib markii birta ka soo baxday dareeraha si buuxda loo walaaqay, ilaa inta suurtogalka ah si loo milo nuugista kaarboonka, heerka soo kabashada kaarboonku wuxuu ku saabsan yahay 50%
In isticmaalka wakiilka carburizing waa in fiiro gaar ah dhibaatada
Haddii wakhtiga lagu daro ee wakiilka carburizing uu yahay mid aad u horeeysa, way fududahay in lagu dhejiyo meel u dhow foornada hoose, iyo wakiilka carburizing ee ku xiran darbiga foornada ma fududa in lagu daro birta dareeraha ah. Taas bedelkeeda, ku darida wakhti aad u daahay, waxay lumin doontaa fursada lagu daro kaarboon, taasoo keentay dhalaalid, wakhtiga kuleylka oo gaabis ah. Tani kaliya maaha inay dib u dhigto wakhtiga falanqaynta isku dhafka kiimikada iyo hagaajinta, laakiin sidoo kale waxay halis gelineysaa waxyeelada ay keento kuleylka xad dhaafka ah. Sidaa darteed, wakiilka carburizing ama habka lagu daro kharashka birta xoogaa xoogaa ah si aad ugu biirto.
Sida kiiska qadar badan oo dheeri ah, waxaa lagu dari karaa foornada induction marka birta dareeraha ah ee kuleylka kuleylka ah ee lagu daro tixgelin, si loo hubiyo in carburizer ee wakhtiga nuugista birta dareeraha ah ee 10Min, oo dhinaca kale ah iyada oo loo marayo walaaqaya electromagnetic Saamaynta kaarburizer si buuxda u nuugista faafinta, si loo hubiyo saamaynta nuugista. Dhanka kale, qadarka nitrogen ee la keeno carburizer waa la dhimi karaa.
Ha ku darin hal mar, ku dar dufcadaha, ugu dambeyntiina dhalaali qayb, ku rid qayb ka mid ah birta kulul (qiyaastii baakidh) bacda, ka dibna ku celi karburiyaha foornada 1-2 jeer, ka dibna ku dheji, ku dar daawaha.
Waxaa jira dhowr arrimood oo ay tahay in fiiro gaar ah loo yeesho:
1. Walaxda kaarburisku way adagtahay in la nuugo (la'aanteed);
2, qaybinta walxaha dambaska wakiilka karburizing maaha mid isku mid ah;
3. Ku biirista oo aad u daahday;
4. Habka lagu biirintu maaha mid sax ah, oo isku xidhid lakab ah ayaa la qaataa. Ka fogow muraayadda birta ee dareeraha ah iyo dharbaaxo badan marka lagu daro;
5. Isku day inaadan isticmaalin wax badan oo daxalaystay.
Astaamaha wakiilka carburizing tayada sare leh
1, xajmiga qaybtu waa dhexdhexaad, porosity waa weyn yahay, xawaaraha nuugista waa dhakhso.
2. Halabuurka kiimikada saafiga ah, karbon sare, baaruud hoose, qaybo waxyeello aad u yar, heerka nuugista sare.
3, qaab dhismeedka crystal graphite wax soo saarka waa wanaagsan yahay, hagaajinaysaa awoodda nucleation birta dareere asalka ah. Kordhi tirada qanjidhada birta ee nodular ee tallaalka, oo kordhi garaafyada nucleus ee foornada korantada ee dareeraha birta. Sifee oo xitaa qaybinta khad fosil ee shubka.
4. Waxqabad heersare ah iyo xasilooni.
Xulashada wakiilka ku habboon carburizing waxay ka caawisaa in la yareeyo kharashyada wax-soo-saarka dhalaalidda, hagaajinta tayada birta dhalaalaysa iyo wax-soo-saarka, si ay warshad dhalaaliso, shubto.
