Wakiilka Carburizing, waxaa loo isticmaalaa in warshadaha birta iyo tuurista, for carburizing, desulfurization iyo qalab kale oo caawimo ah. Sida ugu badan ee loo isticmaalo warshadaynta birta iyo birta ayaa ah in la sameeyo kaarboonka ku gubtay habka birta iyo birta dhalaalaysa iyo ku darida walxaha kaarboon-ku jira.
Habka dhalaalidda birta iyo alaabta birta, inta badan sababtoo ah wakhtiga dhalaalidda, waqti-haysashada, wakhtiga kulaylka iyo arrimo kale, lumista dhalaalka curiyeyaasha kaarboon ee birta dareeraha ah ayaa kordheysa, taasoo keentay hoos u dhac ku yimaada maadada kaarboon ee birta dareeraha ah, taasoo keentay Maaddada kaarboon ee birta dareeraha ah ma gaari karto qiimaha la filayo ee sifaynta. Sidaa darteed, waxaa lagama maarmaan ah in lagu daro alaabta carburizing si loo hagaajiyo kaarboonka birta, taas oo ah wax lagu daro kaabayaal lagama maarmaan u ah wax soo saarka birta tayada sare leh.
Wakiilka kaarburintu marka loo eego soosaarka alaabta ceeriin waxaa loo qaybin karaa: kaarboon alwaax, kaarboon dhuxul, kaarboon kook, graphite.
1. Kaarboon alwaax ah
2. Kaarboon nooca dhuxusha
* Kaarburizer dhuxusha guud ee calcining: Waa wax soo saar yar oo dambas hooseeya iyo baaruud yar oo lagu dhaqo anthracite ganaaxa foornada calcination ka dib qiyaastii 1250 ℃ calcination heerkul sare ah, inta badan laga soo saaro Ningxia, Inner Mongolia. Waxa ku jira kaarboonka guud waa 90-93%. Inta badan waxaa loo isticmaalaa shirkadaha samaynta birta, iyo qaar ka mid ah shirkadaha wax shuba ayaa loo isticmaalaa birta cawlan. Sababo la xiriira qaab-dhismeedka is haysta ee unugyadiisa kaarboon, habka nuugista kulaylku waa mid gaabis ah waqtiguna waa dheer yahay.
* Carburizer-ka asphalt coking: waa ka-soo-saar hydrogenation dhuxusha si loo soo saaro saliid. Waa kaarboon sare, baaruud hoose iyo kaarburizer nitrogen hooseeya oo laga soo saaro daamurka. Waxyaabaha kaarboonku waa inta u dhaxaysa 96-99.5%, nuxurka isbedbeddelaya waa hooseeyaa, qaab-dhismeedku waa cufan, xoogga farsamada iyo xirashada caabbinta qaybaha ayaa ah mid aad u sarreeya, garaafid sahlan.
* Wakiilka kaarbuuraynta kookaha ee biraha: dhuxul shidista dhuxusha, badiyaa waa cupola leh kookaha weyn, marka lagu daro dhalaalinta, laakiin sidoo kale waxaa loo isticmaalaa kaarburinta kharashka birta.
3. Coke (petroleum coke) kaarboon
* Carburizer Coke Calcined: Waa shey ka samaysan coke batroolka hoose ee sulfur sida walxo ceeriin ah, kaas oo lagu farsameeyo foornada calcination at 1300-1500 darajo ka dib marka laga saaro qoyaanka, kacsanaanta iyo wasakhda. Kaarboonka uu ku jiro ee go'an ayaa guud ahaan deggan qiyaastii 98.5%, iyo maadada baaruudku inta badan waa ka yar tahay 0.5% ama 1%. Cufnaantiisu waa mid cufan, ma fududa in la dumiyo, isticmaalkeeduna waa dhexdhexaad. Wax soo saarku wuxuu inta badan ku badan yahay Shandong, Liaoning, Tianjin. Sababtoo ah qiimaha iyo sahayda ee qaybo badan oo ka mid ah wakiilka carburizing ayaa faa'iido leh, suuqa ayaa si ballaaran loo isticmaalaa.
* Wakiilka carburizing batroolka kookaha: coke batroolka ee foornada dhalaalka garaafka ka dib 3000 darajo wax soo saarka heerkulka sare ee alaabada garaafyada, oo leh nuugista degdega ah, karbon sare iyo faa'iidooyinka baaruud hoose. Kaarboonka ku jira waa 98-99%, index index sulfur wuxuu ka hooseeyaa 0.05% ama 0.03%, meelaha wax soo saarka ayaa ku urursan gudaha Mongolia, Jiangsu, Sichuan iyo wixii la mid ah. Hab kale ayaa ka timaadda qashinka goynta electrode graphite, sababtoo ah graphite electrode laftiisa ka dib markii daaweynta graphitization, qashinka sidoo kale loo isticmaali karaa sida wakiilka carburizing ah ee biraha birta.
* Semi-graphitic petroleum koke carburizer: heerkulka garaafiga ma aha mid u sarreeya sida karburizer garaafiga, waxa ku jira kaarboonku guud ahaan waa ka weyn yahay 99.5, maadada baaruudku waxa ay ka sarraysaa karburiyaha garaafiga, oo ka hooseeya 0.3%.
4. Nooca garaafka
*Wakiilka garaafyada dhulka u eg: waa codsiga garaafyada dhulka u eg ee birta iyo birta dhalaalaysa ama tuurista carburizing, aagga wax soo saarka ugu weyn ee Hunan, waa codsiga tooska ah ee budada graphite-ka oo kale ah, badiyaa kaarboonka ku jira 75-80 %, waa la nadiifin karaa si loo kordhiyo kaarboonka alaabta.
Wakiilka carburizing garaafyada dabiiciga ah: inta badan si loo jajabiyo graphite, kaarboonka ku jira 65-99%, xasillooni hooseeya, guud ahaan loo isticmaalo warshadaha birta.
* Wakiilka carburizing ee isku dhafan: budada graphite, budada kookaha, kookaha batroolka iyo agabyada kale ee cagaha, ku darida xirmooyinka kala duwan ee mashiinka ayaa lagu cadaadi karaa qaab ahaan, usha granular. Waxa ku jira kaarboonku guud ahaan waxa uu u dhexeeyaa 93 iyo 97%, waxa ku jira baaruudku waa mid aad u degan, guud ahaan inta u dhaxaysa 0.09 iyo 0.7.
