Farqiga u dhexeeya tuurista kubbadda birta iyo kubbadda birta been-abuurka ah

1.Cast birta birta: birta chromium hoose, birta chromium dhexdhexaad ah, birta chromium sare iyo birta chromium super sare (Cr12% -28%).

2.Forging kubbadda birta: birta daawaha kaarboon hoose, birta daawaha kaarboon dhexdhexaad ah, birta manganese sare iyo naadir dhulka chromium molybdenum alloy birta birta:

Hadda kubbad noocee ah ayaa ugu fiican? Haddaba aan falanqeyno:

1.High index tayada birta chromium: content chromium waa in ka badan 10%, content carbon in 1.80% -3.20% waxaa loo yaqaan bir chromium sare, shuruudaha heerka qaranka ee adkaanta kubbadda chromium sare (HRC) waa in ay ahaataa ≥ 58, AK ≥ 3.0J/cm qiimaha saamaynta

2.Low index tayada birta chromium: oo leh 0.5% ~ 2.5%, content carbon in 1.80% -3.20% waxaa loo yaqaan birta chromium hooseeya, shuruudaha heerka qaran ee adagaanta birta chromium hooseeya (HRC) waa inay ahaadaan≥ 45, AK ≥ 1.5J / cm qiimaha saamaynta 2, Rolling Ball si loo hubiyo tayada kubbadda birta chromium hooseeya heerkulka sare ama gariirka daaweynta gabowga (si loo baabi'iyo walbahaarka tuurista, sida ujeeddada) ee dusha kubbadda birta waa casaan madow si ay u muujiso in alaabtu ay ahayd daaweynta heerkulka sare ee heerkulka, sida dusha kubbadda birta waa midabka birta ayaa tilmaamaya badeecada iyada oo aan xanaaqin. .

3.Foojinta tayada kubbadda birta: oo leh 0.1% ~ 0.5% (kubbada birta been abuurka ah ee aan lahayn chromium), kaarboonka ka hooseeya 1% iyo kubbadda birta oo leh heerkul sare oo wax soo saar leh, qaar ka mid ah qallafsanaanta kubbadda birta ee foornada (HRC) ≥ 56 ( in kasta oo ay ku guulaysan karto in ka badan lakabka deminta kaliya 15 mm ama wax ka badan), kubbadda birta sababta oo ah kubbadda birta la been abuurtay ayaa adkaysay adkaanta xudunta u ah guud ahaan waa 30 oo keliya. shahaadooyinka. Duruufaha caadiga ah, kubbadda birta been abuurka ah ee daawaynta biyaha lagu demiyo, kubbadda birta been abuurka ah ee jabtay waa sarraysaa.

4.Comparison of wear resistance: super high chromium steel> birta chromium sare> kubbadda birta chromium dhexdhexaad ah> birta chromium hoose> kubbad bir been abuur ah.

Qaybaha kubbadda birta ah ee u adkaysata xidhashada:

Waxyaabaha ku jira Chromium waa 1% - 3% iyo adkaanta HRC ≥ 45. Heerkan kubbadda birta u adkeysaneysa xirashada waxaa lagu magacaabaa kubbadda kabka ee chromium alloy low. Kubadaha chromium-ka hooseeya waxay qaataan foornada korantada ee inta jeer ee dhexdhexaadka ah, caaryada birta ah ama qaabka shubista ciidda. Wax qabadkeedu wuxuu ku habboon yahay qaar ka mid ah miinooyinka birta ah, slag iyo warshadaha kale, kuwaas oo ah saxnaanta shiididda hooseeya iyo isticmaalka hooseeya.

Kubbada birta ee chromium-ka ku jirta ee u adkaysata waa 4% ilaa 6% iyo adkaanta HRC ≥ 47. Heerkan waxa loo yaqaan kubbadaha daawaha badan ee element-ka ah, kaas oo ka sarreeya birta chromium-ka hooseeya ee tilmaamaysa xoogga iyo xidhashada caabbinta. Waxyaabaha ku jira Chromium waa 7% - 10% iyo adkaanta HRC ≥ 48 waa kubbadaha kabka ee chromium alloy, kuwaas oo wax qabadkooda iyo dhinacyo kale ay ka sarreeyaan kubbadaha birta ah ee badan.

Kubbada birta ee chromium-ka ee xidhashada u adkaysata ≥ 10% – 14% iyo adkaanta HRC ≥ 58. Kubadaha shubka chromium alloy-ga sarreeya waa nooc ka mid ah kubbadda birta u adkaysta oo leh heer sare oo lagu dabaqi karo iyo waxqabadka qiimaha wanaagsan ee suuqa hadda jira. Kala duwanaanshaheeda codsigu waa ballaadhan yahay waxaana loo isticmaalaa birta, sibidhka, awoodda kulaylka, desulfurization gaaska flue, qalabka magnetic, kiimikooyinka, bamka biyaha dhuxusha; kubbadda sidaas darteed, budada superfine, slag, dambaska duulista, kaalshiyam carbonate iyo warshadaha quartz-sand. Shaqadeeda ayaa lagu muujiyay gaar ahaan warshadaha sibidhka, taas oo kordhin karta wax soo saarka oo yareyn karta isticmaalka tamarta.
