Kukanganisa kwekunze kwekunze kweseamless chubhu (smls):
1. Kupeta kukanganisa
Kugovera kusingaite: Kana mold slag ikaramba iri munharaunda pamusoro peinoramba ichikanda slab, zvakadzika kupeta zvirema zvichaonekwa pamusoro pekunze kwechubhu yakakungurutswa, uye inogovaniswa kureba, uye "mabhuru" achaonekwa pane dzimwe nzvimbo dzepamusoro. .Kupeta kudzika kwechubhu yakakungurutswa kunosvika 0.5 ~ 1mm, uye kupeta kupeta kwainoenda i40 ° ~ 60 °.
2. Kupeta kwakakura
Longitudinal distribution: Crack defects uye hukuru hwekupeta hurema hunooneka pamusoro peinoramba ichikanda slab, uye inogoverwa kureba.Zvizhinji zvekudzika kwakadzika pamusoro pemachubhu esimbi asina musono anenge 1 kusvika 10 mm.
3. Zvirema zvidiki zvinotsemuka
Paunenge uchiyedza machubhu esimbi asina musono, pane hurema hwepamusoro pamadziro ekunze emuviri wepombi izvo zvisingagoni kucherechedzwa nemeso asina kupfeka.Kune akawanda madiki akapeta akaremara pamusoro pepombi yesimbi isina musono, kudzika kwakadzika kunosvika 0.15mm, pamusoro pepombi yesimbi isina musono yakafukidzwa neruzhowa rwesimbi oxide, uye kune decarburization layer pasi pesimbi oxide, kudzika kunosvika 0.2mm.
4. Linear defects
Pane mitsara yakakanganisika pamusoro pekunze kwechubhu yesimbi isina musono, uye hunhu hwacho hwakadzika kudzika, kuvhurika kwakafara, kuzasi kunoonekwa, uye hupamhi hunoramba huripo.Rusvingo rwekunze rwemuchinjiko wepombi yesimbi isina musono inogona kuoneka nemakwara ane hudzamu hwe<1mm, ari muchimiro chegorofu.Mushure mekurapa kwekupisa, kune oxidation uye decarburization pamucheto we groove yepombi.
5. Mavanga akaremara
Pane hurema hwegomba husina kudzika pamusoro pekunze kwechubhu yesimbi isina musono, ine hukuru hwakasiyana nenzvimbo.Iko hakuna oxidation, decarburization, uye aggregation uye inclusions yakatenderedza gomba;iyo tishu yakakomberedza gomba inosvinwa pasi pekushisa kwepamusoro, uye epurasitiki rheological maitiro achaonekwa.
6. Kudzima mutswe
Kudzima uye kupisa kupisa kurapwa kunoitwa pane isina musono simbi chubhu, uye longitudinal akatsemuka akatsemuka kuoneka pamusoro pekunze, ayo akagoverwa mitsetse neimwe upamhi.
Kukanganisa kwakajairika mukati kwemukati kwemachubhu asina musono:
1. Convex hull kukanganisa
Macroscopic maficha: Mudhuri wemukati wechubhu isina musono wakagovera zvisina tsarukano diki longitudinal convex kuremara, uye kureba kweizvi zvidiki convex hurema hunosvika 0.2mm kusvika 1mm.
Microscopic maitiro: Kune cheni-yakaita nhema-grey inclusions kumuswe, pakati uye yakatenderedza ye convex hull kumativi ese emukati madziro emuchinjiko-chikamu chepombi isina musono yesimbi.Rudzi urwu rweblack-grey chain rine calcium aluminate uye shoma shoma yecomposite oxides (iron oxide, silicon oxide, magnesium oxide).
2. Chirema chakarurama
Macroscopic features: Straight-type defects inoonekwa mumachubhu esimbi asina musono, ane humwe hudzamu nehupamhi, hwakafanana nekukwenya.
Microscopic maitiro: Madhiri ari mukati memadziro emukati emuchinjiko-seamless simbi chubhu ari muchimiro chegorozi rine hudzamu hwe1 kusvika 2 cm.Oxidative decarburization haioneki kumucheto kwegorofu.Iyo yakakomberedza tishu ye groove ine hunhu hwesimbi rheology uye deformation extrusion.Pachave nemamicrocracks nekuda kwekukura extrusion panguva yekuita saizi.
