Birta Ductile | Usha Birta ee SG ee la Machin karo
Hordhac Badeecada
Birta Ductile Iron Bar oo Xoog Badan leh waa walax heer sare ah oo si gaar ah loogu farsameeyay qaybaha farsamada ee u baahan adkeysi iyo shaqeyn labadaba. Sidoo kale loo yaqaan SG Iron ama Spheroidal Graphite Iron, walaxdani waxay isku daraysaa dabacsanaanta shubista birta iyo sifooyinka farsamada ee u dhow birta. Iyada oo leh xooggeeda gaarka ah, awooddeeda farsamo ee aadka u fiican, iyo awoodaha yareynta gariirka, birta ductile birtu waxay noqotay doorashada la doorbiday ee codsiyada warshadaha ee kala duwan, oo ay ku jiraan nidaamyada haydarooliga, qaybaha mashiinka, iyo qaybaha gudbinta korontada.
Si ka duwan birta cawlan, birta ductile waxay leedahay graphite qaab wareegsan, taas oo kor u qaadaysa xooggeeda iyo iska caabbinta saameynta. Faa'iidadan qaab-dhismeedka yar yar waxay siinaysaa adkeysi sare xaaladaha culeyska culus, taasoo ka dhigaysa mid ku habboon culaysyada taagan iyo kuwa firfircoon labadaba. Ulaha birta ductile waxaa laga heli karaa dhexroor kala duwan waxaana lagu bixin karaa xaalado qallafsan ama sax ah si ay ula jaanqaadaan shuruudaha warshadaha ee kala duwan.
- baararka birta ee ductile waxaa loo soo saaraa si waafaqsan heerarka caalamiga ah. Darajooyinka birta ee caadiga ah ee loo isticmaalo baararka birta ee ductile waxaa lagu muujiyaa siyaabo kala duwan iyadoo loo eegayo waddamada iyo heerarka kala duwan.
Kuwa soo socda waa heerarka birta ductile ee badanaa loo isticmaalo (darajooyinka) ee dhowr nidaam oo caadi ah:
| ASTM A536 | 1563kii | ISO 1083 | JIS G5502 |
| 60-40-18 | EN-GJS-400-15 | GGG40 | FCD400 |
| 65-45-12 | EN-GJS-450-10 | - | FCD450 |
| 80-55-06 | EN-GJS-500-7 | GGG50 | FCD500 |
| 100-70-03 | EN-GJS-600-3 | GGG60 | FCD600 |
Sharaxaadda Badeecada
Birta Ductile waa walax hagaajisa sifooyinkeeda farsamada iyadoo lagu darayo walxo spheroidizing ah sida magnesium ama cerium si loogu shubo birta si loo sameeyo graphite qaab-dhismeed wareegsan. Marka la eego halabuurka kiimikada, qaybaha ugu muhiimsan ee birta ductile waa bir, kaarboon, silikoon, iyo sidoo kale manganese, fosfooraska, sulfur iyo walxo kale. Ku darista wakiilada spheroidizing sida magnesium ama cerium waa furaha, taas oo kor u qaadaysa sameynta qaab-dhismeed wareegsan oo ku jira graphite.
Ulaha birta ah ee loo yaqaan "ductile iron" waxaa badanaa loo isticmaalaa meelaha sida geerka iyo qaybaha usha ee wax soo saarka farsamada, shaftyada crankshafts iyo ulaha isku xira warshadaha baabuurta, tuubooyinka iyo qaybaha dhismaha ee goobta dhismaha, qaybaha haydarooliga ee mashiinnada dhismaha, iyo waalka iyo walxaha bamka ee warshadaha tamarta.
