Kuwotcherera kamwazi AN348A

Kamwazi - ndi chuma chochuluka cha mankhwala kuti ntchito kuti lithandizire njira zonse mitundu ya kuwotcherera. Uyamiko kwa Iye, chikugwirizana zipangizo china chotulutsa. Mmodzi wa mitundu yotchuka kwambiri ya chuma ndi kamwazi AN348A.

N'chifukwa chiyani nkhaniyi?

Kamwazi AN348A (GOST 9078-81) ntchito kuwotcherera Arc. Iye amateteza Arc ndi china chotulutsa dziwe chifukwa cha zinthu zachilengedwe. Komanso, kamwazi ndi okhoza kuthandiza mu processing wa welds zitsulo.

Pamene kuwotcherera (cladding) kamwazi chimakwirira waya. Zimenezi Mwachangu matenthedwe. AN348A kamwazi ntchito pa kuwotcherera magetsi, kuteteza malo ntchito kwa mpweya ndi mpweya wina. Izi amalenga ndi koyenera kuti ntchito yake yolalikira imene imapereka maphunziro apamwamba china chotulutsa.

Kodi kutsatira

Zobwezeretsa zipangizo wosweka ndi zigawo Nthawi zambiri kudzera kuwotcherera. Njira imeneyi zimathandiza inu ndalama ndi nthawi. Dongosololi sadzakhala yaitali. Uyamiko kwa Iye, si koyenera kuti tidikirire motalika kwa zida zosinthira, zimene ziyenera "posakhalitsa" kubwera.

Pa kuwotcherera kamwazi AN348A ndi waya imayambira pamodzi mu zone arcing. Pali amapezeka limatsogolera a m'munsi zitsulo m'mbali, mawaya ndi kamwazi. Chifukwa, kuwira padziko Arc pamaoneka, wopangidwa mwa gasi zitsulo ndi zinthu kamwazi. Kupita Arc kamwazi Sungunulani limatuluka pamwamba pa china chotulutsa dziwe. Izi ndipamene slag. Izi ndi kuteteza pamwamba pa mpweya osafunika. China chotulutsa yosalala, apamwamba. Pambuyo akamazizira slag mkate mosavuta kuchotsedwa.

Kuwonjezera katundu pamwamba ananena kuti, akhoza kuteteza owotcherera kamwazi panamveka kuchokera ku mipweya zoipa ndi fumbi.

Kamwazi AN348A: zofunika

Nkhanizi yambewu woderapo. kukula wawo uli pafupi 0.35-0.5 ml. Tirigu dongosolo lawo amafanana zidutswa za galasi. chochuluka awo kachulukidwe ndi mu zosiyanasiyana 1.3-1.8 makilogalamu / DM ^3. Pamene ntchito chuma ayenera mu chikhalidwe youma. Ngati izo siziri, nthaŵi zonse ayenera kukhala wouma. Chifukwa chaichi, ndi zouma kwa ola pa + 300-400 ⁰ C.

Mmodzi mwa makhalidwe ofunika kwambiri fluxes ndi reactivity awo. Mu AN348A mtengo uwu mu uthunthu 0.7-0.75 AF. Izi zikutanthauza kuti AN348A kamwazi anafotokoza kuti gulu kwambiri yogwira. Pa njira kuwotcherera ntchito zinthu wolemekezeka radiative umuna, mtengo wa Chofanana anakhazikitsa mfundo malamulo (zosaposa 18 Mr / hr).

The zikuchokera kamwazi zikuphatikizapo oxides pakachitsulo (mpaka 44% buku okwana zinthu), manganese (mpaka 38%), calcium (mpaka 12%), magnesium (mpaka 7%), zotayidwa (mpaka 13%) ndi chitsulo (mpaka 2.2 %). Komanso, pali sulfure ndi phosphorous. Mulinso tinthu akunja kukhalabe zinthu pa kupanga ndondomeko (monga zatsalira malasha, coke, graphite, zitsulo tchipisi, etc.).

AN348A kamwazi angagwiritsidwe ntchito m'malo osiyanasiyana ndi osiyanasiyana kutentha yozungulira. Iwo ali osavomerezeka ntchito mu North pa otsika kutentha kwambiri (m'munsimu -30 ⁰ C).
