Txheej txheem ntau lawm
1.Raw khoom melting: Xaiv siab - zoo npua hlau, seem hlau, yaj rau hauv cov hlau molten saum 1500 degree, tswj cov khoom nruj me ntsis;
2.Spheroidization & inoculation: Ntxiv spheroidizing thiab inoculating cov neeg ua haujlwm kom zoo dua cov khoom siv zog thiab toughness;
3.Casting forming: Sand casting ib tus qauv EN124, cam khwb cia ntawm txog 1400 degree;
4.Post-kev kho mob: Kev kho cua sov kom txo tau kev ntxhov siab tom qab txias, ua tiav machining, tsuag tshuaj tiv thaiv- txheej txheej;
5.Assembly & testing: Nruab pob khawm, ntsaws ruaj ruaj, dhau D400 load test rau tus me nyuam.Heavy luag hauj lwm ductile hlau manhole npog nrog hinged txheej txheem yog npaum thiab ua raws.
Cov khoom soj ntsuam
A.Material muaj pes tsawg leeg kuaj: Paub meej tias cov hlau ua tau raws li GGG50 / QT500-7 tus qauv, nrog rau cov pa roj carbon, silicon, magnesium cov ntsiab lus;
B.Dimensional raug kuaj: ntsuas lub cheeb txoj kab uas hla, thickness, ncej haum clearance, ua raws li EN 124 kam rau ua;
C.Mechanical kev xeem: Tensile zog Ntau tshaj los yog sib npaug rau 500MPa, elongation Ntau tshaj los yog sib npaug rau 7%, D400 / E600 / F900 chav kawm load xeem;
D.Structural function test: Pob khawm qhib lub kaum ntse ntse (Ntau dua lossis sib npaug ntawm 110 degree), kev ruaj ntseg xauv, foob lub nplhaib tsis muaj dej tsis zoo / plua plav pov thawj;
E.Surface zoo xeem: Tsis muaj kab nrib pleb, xuab zeb qhov, thiab lwm yam., tiv thaiv -corrosion txheej adhesion thiab corrosion kuj;
F.Kev nyab xeeb kev ua tau zoo: Kev tiv thaiv-tsav, tiv thaiv- dhia, tiv thaiv- pov thawj muaj nuj nqi.
