Kor u qaadida amniga warshadaha iyo hufnaanta leh adeegsiga saxda ah ee muqaqda garaacista

Sanadihii ugu dambeeyay, codsigaClaphite CruciblesIn lagu tuuro birta birta iyo tuurista ayaa si isdaba joog ah u sii kordhaya, isaga oo u mahadceliya qaabeynta ku saleysan dhoofinta ee ku saleysan caabbinta heerkulka sare ee ugu sarreeya. Si kastaba ha noqotee, adeegsi wax ku ool ah, inbadan ayaa iska indhatiraya geedi socodka xoojiya ee muhimka ah ee khudradda cusubi ee cusub, taasoo horseedaysa khataraha ka imaan kara nabadgelyada shaqsiyeed iyo hantida awgood sababtuna tahay jahwareebkaaga. Si loo kordhiyo faa'iidooyinka muhiimka ah ee garaacista garaacista, waxaan bixinaa talooyin cilmiyeed ku saleysan isticmaalkooda saxda ah, hubinta wax soo saarka hufan iyo badbaadada warshadaha.

Astaamaha ku saabsan khudbadaha garaacista

Craphite Cruciles-ka waxay door muhiim ah ka ciyaaraan birta iyo tuurista sababtoo ah xaga xaga kuleylka. In kasta oo ay soo bandhigaan fal-galyo si ka wanaagsan oo loo barbardhigo silicon Carbide Carbides, waxay u nugul yihiin oksidation waxayna leeyihiin heerar sare oo jabinta. Si wax looga qabto arrimahan, waxaa muhiim ah in la shaqaaleeyo geedi socodka cilmiga saynis ahaaneed.

Tilmaamaha Preheat

1. Meelaynta u dhow foornada shidaalka ee ka-hortagga 'preheating' Nidaamkan ka-hortagga deeq-lacageedka ah ee ku jira demuuska dusha sare, kor u qaadista xasilloonida iskutallaabta ah.
2. Gubashada dhuxusha ama alwaax: Dhig dhuxul ama qoryo gudaha ah oo gubanaya oo gubanaya qiyaastii afar saacadood. Tallaabahan ayaa ka caawiya deHUMIDIIDID wuxuuna wanaajiyaa iska caabinta kuleylka ee iskuxiran.
3. Wadada heerkulka foornada: inta lagu gudajiro marxaladda kuleylka ee bilowga ah, si tartiib tartiib ah u kordhi heerkulka foornada ku saleysan marxaladaha soo socda si loo hubiyo xasilloonida iyo sugidda xasilloonida:
   • 0 ° C illaa 200 ° C: gaabis kuleylka 4 saacadood (foornada saliida) / korantada
   • 0 ° C ilaa 300 ° C: gaabis kuleylka 1 saac (korantada)
   • 200 ° C illaa 300 ° C: gaabis kuleyl 4 saacadood (foorno)
   • 300 ° C illaa 800 ° C: gaabis kuleylka 4 saacadood (foornada)
   • 300 ° C illaa 400 ° C: gaabis kuleylka 4 saacadood
   • 400 ° C illaa 600 ° C: kuleyl deg deg ah, dayactirka 2 saacadood
4. DIIWAANKA DIIWAANKA GUUD: Ka dib markaad xidho, kululeeyaha waqtiga loogu talagalay saliida iyo foornada korantada waa sida soo socota:
   • 0 ° C ilaa 300 ° C: gaabis kuleylka 1 saac
   • 300 ° C illaa 600 ° C: gaabis kuleylka 4 saacadood
   • Ka sarreysa 600 ° C: Kuleyl deg deg ah oo kuleylka loo baahan yahay

Tilmaamaha xiritaanka

• Loogu talagalay foornada korantada, waxaa lagugula talinayaa in la ilaaliyo dahaarista joogtada ah marka shaqo la'aan, heerkulka loo dejiyo qiyaastii 600 ° C si looga hortago qaboojinta degdegga ah. Haddii ay tahay in ay suurtagal ahayn suurtagal, soo saar agab ka soo baxa iskutallaabta si loo yareeyo waxyaabaha haraaga ah.
• Loogu talagalay foornada saliidda, ka dib xiritaanka, hubi inaad ka baxdo waxyaabaha ugu badan ee suuragalka ah. Xir daboolka foornada foornada iyo dekedaha hawo-mareenka si loo ilaaliyo kuleylka hadhaaga ah oo looga hortago qoyaanka khafiifka ah.

Adoo ku horimanaya Tilmaamahaan Samida ee Samirta ah ee Samirta ah oo xiritaanka Tilmaamaha, Waxqabadka ugu habboon ee garaacista digniinta ee wax soo saarka warshadaha ayaa la hubin karaa, si isku mid ah kor u qaadida amniga wax soo saarka iyo ilaalinta amniga warshadaha. Aynu wada ururinno si wadanka u halgamaynta farsamada si aan u wadno horumarka warshadaha.
