HONGDA Ductile iron castings:
Mathoasong a 2021, HONGDA e ile ea haha fektheri e ncha ho hlahisa lisebelisoa le mohala oa tlhahiso bakeng sa Ductile Iron casting.
1. Boitsebiso: QT450#-10 le sekhahla sa Spheroidization se feta boemo ba III ho fumana boleng bo botle ba ho bapala ho tšehetsa kopo ea hau.
2. Mohala oa tlhahiso o ikemetseng ho fihlela katleho e phahameng le tlhahiso e kholo ea bokhoni, 550T / Khoeli, ho khutlisetsa tlhoko ea hau e potlakileng.
3.Applications: ductile iron castings for roller collar, idler bracket and so like parts castings ka hare ho 70KGS. Mosebetsi oa li-roller tse holimo ke ho jara sehokelo sa pina holimo, ho etsa hore lintho tse itseng li hokahane ka thata, le ho nolofalletsa mochine hore o sebetse ka potlako le ho feta. butle-butle.Lihlahisoa tsa rona li sebelisa tšepe e khethehileng 'me li hlahisoa ke mokhoa o mocha.Ts'ebetso e 'ngoe le e' ngoe e feta ka tlhahlobo e tiileng 'me thepa ea ho hanyetsa khatello le ho hanyetsa tsitsipano e ka netefatsoa.
