Kukora Kwemadziro: 0.035 mukati (0.9mm)≤ WT ≤0.500 mukati (12.7mm)
Machubhu ane mamwe mativi anogona kupihwa, chero machubhu akadaro achienderana nezvimwe zvese zvinodiwa zveichi chirevo.
Raw Materials
Maitiro ekugadzira simbi--Simbi yacho inofanira kuurayiwa.
simbi yakaurayiwa inoreva kuwedzerwa kwezvimwe zviwandu zve deoxidizers sesilicon, aluminium, uye manganese panguva yekunyunguduka kwesimbi.
Izvi zvinowedzera zvinogona kuita neokisijeni musimbi kuti ibudise okisidhi yakasimba, nokudaro kuderedza okisijeni mukati mesimbi uye kudzivirira kuumbwa kwe oxidizing inclusions.
ASTM A210 Giredhi
ASTM A210 inowanikwa mumakiredhi maviri:Giredhi A-1 uye Giredhi C.
ASTM A210 Seamless Simbi Tube Kugadzira Maitiro
Mapombi esimbi achagadzirwa nenzira isina musono uye ichaveinopisa-yapera or kutonhora-kupedzasezvataurwa.
Kazhinji, mapaipi esimbi ane dhayamita anopfuura 30 millimeters anopisa-apera uye ayo ane dhayamita isingasviki kana kuenzana nemamirimita makumi matatu anotonhora-apera.Iyi nzira yekusiyanisa haina mhedziso asi inogona kushandiswa sekukurumidza uye nyore nzira yekuona nzira yekugadzirisa yesimbi isina musono pombi.
Kupisa Kurapa
Kurapa kwekupisa hakudiwi kune kupisa-kupedzwa kwechubhu.
Machubhu anotonhora anopera achapihwa subcritical anneal, anneal yakazara, kana normalizing kupisa kurapwa mushure mekupedzisira kutonhora-kupedza maitiro.
