Kugadzirwa kwepamusoro-simba alloy simbi mapaipi
Iyo nzira yekugadzira yesimbi isina musono pombi yakakamurwa kuita yekuchinjisa nzira (Mennesmann nzira) uye extrusion nzira.Nzira yekuchinjika (Mennesmann method) ndeyekutanga kuboora chubhu isina chinhu necross-roller, wozoiwedzera nechigayo.Iyi nzira ine kukurumidza kugadzira kukurumidza, asi inoda yakakwirira machinability yechubhu isina chinhu, uye inonyanya kukodzera kugadzirwa kwekabhoni simbi uye yakaderera-alloy simbi machubhu.
Iyo extrusion nzira ndeyekuboora chubhu isina chinhu kana ingot nemuchina wekuboora, uye woiburitsa mupombi yesimbi ine extruder.Iyi nzira haina kunyatsoshanda kupfuura skew rolling nzira uye yakakodzera kugadzirwa kwepamusoro-simba alloy steel pipes.
Zvose skew rolling nzira uye extrusion nzira inofanira kutanga yapisa chubhu isina chinhu kana ingot, uye inogadzirwa simbi chubhu inonzi hot-rolled chubhu.Mapombi esimbi anogadzirwa nenzira dzinopisa dzekushanda dzimwe nguva anogona kutonhora kushanda sezvinodiwa.
Kune nzira mbiri dzekushanda kunotonhora: imwe inotonhora yekudhirowa nzira, inova yekukwevera pombi yesimbi kuburikidza nedhirowa inofa kuti zvishoma nezvishoma itete uye kurebesa pombi yesimbi;
Imwe nzira inzira inotonhora yekukungurutsira, inova nzira yekushandisa chigayo chinopisa chakagadzirwa neMennesmann Brothers kukushanda kunotonhora.Kushanda kunotonhora kwepombi yesimbi isina musono kunogona kuvandudza kurongeka kwedimensional uye kugadzirisa kupera kwepombi yesimbi, uye kunatsiridza michina yezvinhu.
Kugadzira nzira yesimbi isina musono pombi (inopisa-yakakungurutswa simbi pombi)
Kusagadzikana kwepombi yesimbi kunonyanya kupedzwa nekudzikisira tension, uye maitiro ekuderedza kushushikana inzira inoenderera mberi yekukungurutsa kwesimbi base isina mandrel.Pasi pemamiriro ekusimbisa kunaka kwepombi yemubereki, iyo welding pombi yekumanikidza kudzikisa maitiro ndeyekupisa iyo welded pombi yakazara kusvika kune anopfuura 950 madhigirii Celsius, uye woitenderedza mumadhayamita ekunze akasiyana-siyana uye madziro nechidzikisiro chekumanikidza. huwandu hwemakumi maviri nemana anopfuura eanoderedza kushushikana).Papombi dzakakora dzakapedzwa, mapaipi anopisa anokungurutswa esimbi anogadzirwa neichi maitiro akasiyana zvakanyanya kubva kune akajairwa akakwira-frequency welded pombi.Iyo yechipiri tension reducer rolling uye otomatiki kudzora inoita kuti dimensional iko kwepombi yesimbi (kunyanya kutenderera uye kukora kwemadziro kurongeka kwemuviri wepombi) zviri nani pane iyo yemapombi asina musono.
