EN-GJS 400-15 / 500-7 Ductile Iron Bars | Chitsulo cha Spheroidal Graphite
Chiyambi cha Zamalonda
EN-GJS 400-15 / 500-7 Ductile Iron Bars ndi zinthu zopangidwa ndi chitsulo chopangidwa motsatira miyezo ya ku Europe, zomwe zimapangidwa makamaka kuti zigwiritsidwe ntchito zomwe zimafuna mphamvu zambiri, kusinthasintha bwino, komanso makina apamwamba. Mipiringidzo iyi imapangidwa ndi kapangidwe ka graphite kakang'ono, komwe kamapereka mphamvu zodabwitsa zogwirira ntchito komanso kukana kugwedezeka, zomwe zimapangitsa kuti ikhale yosankha yogwiritsidwa ntchito mosiyanasiyana pakupanga ndi makina.
Mndandanda wa EN-GJS umayamikiridwa kwambiri ku Europe chifukwa chopereka mitundu yosiyanasiyana ya mphamvu ndi kutalikitsa. EN-GJS 400-15 imadziwika ndi kulimba komanso kulimba kwabwino kwambiri, pomwe EN-GJS 500-7 imapereka mphamvu zambiri pamene ikusunga kusinthasintha koyenera. Mipiringidzo yachitsulo yozungulira iyi ndi yoyenera pazinthu zomwe zimakumana ndi kupsinjika mobwerezabwereza, kugwedezeka, kapena kugwedezeka pang'ono. Kugwira ntchito kwawo bwino kumawapangitsa kukhala abwino kwambiri pa ntchito zonse ziwiri zozungulira komanso zomaliza molondola.
- zitsulo zopangidwa ndi ductile zimapangidwa motsatira miyezo yapadziko lonse lapansi. Mitundu yachitsulo yomwe imagwiritsidwa ntchito kwambiri ya zitsulo zopangidwa ndi ductile imafotokozedwa m'njira zosiyanasiyana malinga ndi mayiko ndi miyezo yosiyanasiyana.
Zotsatirazi ndi magiredi achitsulo chachitsulo chopangidwa ndi ductile (magiredi) omwe amagwiritsidwa ntchito kwambiri m'machitidwe angapo ofanana:
| ASTM A536 | MU 1563 | 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 |
Mafotokozedwe Akatundu
Chotsukira chitsulo chopangidwa ndi ductile ndi chinthu chomwe chimawongolera mphamvu zake zamakaniko powonjezera zinthu zosungunulira monga magnesium kapena cerium kuti zipange chitsulo kuti chipange graphite kukhala chozungulira. Ponena za kapangidwe ka mankhwala, zigawo zazikulu za chitsulo chosungunuka ndi chitsulo, kaboni, silicon, komanso manganese, phosphorous, sulfure ndi zinthu zina. Kuwonjezera zinthu zosungunulira monga magnesium kapena cerium ndikofunikira, zomwe zimathandiza kuti pakhale chozungulira mu graphite.

Mapulogalamu Ogulitsa
Mipiringidzo yachitsulo ya EN-GJS imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo:
>Zipangizo zamakina monga magiya, ma pulley, ndi ma shaft
>Zigawo za kapangidwe ka makina a mafakitale
>Matupi a ma valve ndi manifolds a hydraulic
>Mabulaketi a magalimoto ndi ma differential housings
>Zipangizo zokwezera ndi kukweza
>Zida zamakina a ulimi
