Shijiazhuang Donghuan chitsulo chosungunula chitsulo kuponyera TACHIMATA mchenga kuponyera ndondomeko

Lero, ndikupita nanu ku Donghuan Malleable Iron Casting Co., Ltd. Tiyeni tiphunzire za kaponyedwe ka mchenga wokutidwa.

I. Kudziwa ndi kumvetsetsa mchenga wokutidwa

1. Zinthu za mchenga wokutidwa

Iwo ali oyenera mphamvu ntchito; madzi abwino, nkhungu zamchenga zokonzekera ndi mchenga wa mchenga zimakhala ndi ma contours omveka bwino ndi zomangamanga, zomwe zimatha kupanga mchenga wovuta; nkhungu zamchenga (cores) zimakhala ndi mawonekedwe abwino, ndipo kuuma kwapamwamba kumatha kufika Ra = 6.3 ~ 12.5μm, Kulondola kwazithunzi kumatha kufika pamlingo wa CT7～CT9; kukomoka ndikwabwino, ndipo kuponyera ndikosavuta kuyeretsa.

2. Kuchuluka kwa ntchito

Mchenga wokutidwa ukhoza kugwiritsidwa ntchito popanga nkhungu ndi mchenga. The zisamere pachakudya kapena m'miyendo ya mchenga wokutira angagwiritsidwe ntchito limodzi kapena ndi zina zisamere mchenga (cores); sizingagwiritsidwe ntchito poponya chitsulo chokoka kapena kuponyera pang'onopang'ono, komanso chitha kugwiritsidwa ntchito poponya chitsulo chophimbidwa ndi mchenga ndi kuponyera kwapakati pa matenthedwe; itha kugwiritsidwa ntchito osati kupanga zitsulo zotayidwa komanso zopanda chitsulo, komanso kupanga zitsulo zachitsulo.

II. Kukonzekera kwa TACHIMATA mchenga

1. Kupangidwa kwa mchenga wokutidwa

Nthawi zambiri amapangidwa ndi zomangira, zomangira, zochiritsa, zothira mafuta ndi zina zapadera.

2. Njira yopanga mchenga wokutidwa

Kukonzekera kwa mchenga wokutidwa makamaka kumaphatikizapo kuphimba kozizira, kutenthetsa, ndi kutenthetsa. Pakali pano, pafupifupi kupanga mchenga wokutira kumatengera njira yotentha yotentha.

3. Main mankhwala mitundu ya TACHIMATA mchenga

(1) Mchenga wamba wokutidwa ndi mchenga wamwambo

(2) Mchenga wokutidwa wamphamvu kwambiri komanso wocheperako

Mawonekedwe: mphamvu yayikulu, kukulitsa kochepa, mpweya wochepa, mpweya wocheperako, anti-oxidation

(3) Kutentha kwakukulu (mtundu) wokutidwa mchenga (ND mtundu)

Mawonekedwe: kukana kutentha kwambiri, mphamvu yayikulu, kukulitsa kochepa, mpweya wochepa, mpweya wocheperako, kugwa kosavuta, anti-oxidation

(4) Mchenga wokutidwa mosavuta

Zili ndi mphamvu zabwino komanso zotsika kwambiri zotsika kutentha, zomwe zimayenera kupanga zitsulo zopanda chitsulo.

(5) Zofunikira zina zapadera zokutira mchenga.

III. Waukulu ndondomeko pachimake kupanga ndi TACHIMATA mchenga

Kutentha kwa kutentha ndi 200-300 ℃, nthawi yochiritsa ndi 30-150s, ndipo kuthamanga kwa mchenga ndi 0.15-0.60MPa. Pamiyendo yamchenga yokhala ndi mawonekedwe osavuta ndi mchenga wokutidwa wokhala ndi madzi abwino, kuthamanga kocheperako kumatha kusankhidwa. Kwa mchenga wochepa thupi, kutentha kocheperako kumatha kusankhidwa. Kutentha kukakhala kocheperako, nthawi yochiritsa imatha kukulitsidwa moyenera. Utoto womwe umagwiritsidwa ntchito mumchenga wokutidwa ndi phenolic resin. Ubwino wa njira yopangira maziko: magwiridwe antchito amphamvu; madzi abwino; zabwino pamwamba pa mchenga pachimake (Ra = 6.3-12.5μm); kukana kwambiri chinyezi chapakati pa mchenga; kukomoka bwino komanso kuyeretsa kosavuta kwa castings.

1. Kutentha kwa nkhungu (nkhungu).

Kutentha kwa nkhungu ndi chimodzi mwazinthu zazikulu zomwe zimakhudza makulidwe ndi mphamvu ya chipolopolo, chomwe chimayendetsedwa pa 220 ~ 260 ℃

2. Kuthamanga kwa mchenga ndi nthawi

Nthawi yowombera mchenga nthawi zambiri imayendetsedwa pa 3 ~ 10s. Ngati nthawiyo ndi yochepa kwambiri, nkhungu ya mchenga (pachimake) sichingapangidwe. Kuthamanga kwa mchenga kumakhala pafupifupi 0.6MPa; pamene kupanikizika kuli kochepa kwambiri, n'zosavuta kuyambitsa kuwombera kosakwanira kapena kumasuka. Nthawi yowumitsa: Kutalika kwa nthawi yowumitsa makamaka kumadalira makulidwe a nkhungu yamchenga (pakati) ndi kutentha kwa nkhungu, nthawi zambiri pafupifupi 60-120s.

Pakali pano, mankhwala athu waukulu ndi malleable chitsulo chitoliro zovekera, zikhomo chubu, zolumikizira chimango, zolumikizira mpweya payipi, awiri bawuti zikhomo, limodzi bawuti payipi clamps, camlock malumikizanidwe, malumikizanidwe kudya, ngalande thupi, KC nsonga zamabele, menders hose ndi oposa mazana a mankhwala kuti musankhe. Takulandilani ku Donghuan Malleable Iron casting kuti mufunse mafunso, tidzakutumikirani moona mtima.
