Zowonongeka zapamtunda zamachubu opanda msoko

Zowonongeka zakunja zakunja za machubu opanda msoko (smls):

1. Chilema chopinda
Kugawa kosakhazikika: Ngati nkhungu imakhalabe pamtunda wa slab mosalekeza, zolakwika zopindika zakuya zidzawonekera kunja kwa chubu, ndipo zidzagawidwa motalika, ndipo "midadada" idzawonekera kumadera ena a pamwamba. .Kuzama kwa chubu chokulungidwa ndi pafupifupi 0.5 ~ 1mm, ndipo njira yopinda yogawa ndi 40 ° ~ 60 °.

2. Chilema chachikulu chopinda
Kugawa kwautali: Kuwonongeka kwa mng'alu ndi zolakwika zazikulu zopindika zimawonekera pamwamba pa slab yopitilira, ndipo imagawidwa motalika.Zozama zambiri zopindika pamwamba pa machubu achitsulo opanda msoko ndi pafupifupi 1 mpaka 10 mm.

 

3. Zowonongeka zazing'ono
Poyesa machubu achitsulo osasunthika, pali zolakwika zapamtunda pakhoma lakunja la thupi la chitoliro lomwe silingathe kuwonedwa ndi maso.Pali zolakwika zambiri zazing'ono zopindika pamwamba pa chitoliro chopanda chitsulo, kuya kwambiri ndi pafupifupi 0.15mm, pamwamba pa chitoliro chopanda chitsulo chophimbidwa ndi wosanjikiza wa chitsulo okusayidi, ndipo pansi pa chitsulo okusayidi pali decarburization wosanjikiza, kuya ndi pafupifupi 0.2mm.

4. Linear zolakwika
Pali zolakwika za mzere kunja kwa chubu chachitsulo chosasunthika, ndipo mawonekedwe ake ndi ozama, kutseguka kwakukulu, pansi powonekera, ndi m'lifupi mosalekeza.Khoma lakunja la mtanda wa chitoliro chachitsulo chosasunthika chikhoza kuwonedwa ndi zokopa ndi kuya kwa <1mm, zomwe ziri mu mawonekedwe a groove.Pambuyo mankhwala kutentha, pali makutidwe ndi okosijeni ndi decarburization m'mphepete mwa poyambira chitoliro.

5. Kuwonongeka kwa zipsera
Pali zolakwika za dzenje zakunja kwa chubu chachitsulo chosasunthika, chokhala ndi makulidwe osiyanasiyana ndi madera.Palibe makutidwe ndi okosijeni, decarburization, ndi aggregation ndi inclusions kuzungulira dzenje;minofu yozungulira dzenje imafinyidwa pansi pa kutentha kwakukulu, ndipo mawonekedwe apulasitiki a rheological adzawonekera.

6. Kuzimitsa mng'alu
Kuzimitsa ndi tempering kutentha mankhwala ikuchitika pa osataya zitsulo chubu, ndi kotenga nthawi ming'alu zabwino kuonekera pa kunja, amene anagawira n'kupanga ndi m'lifupi ena.

Zowonongeka zamkati zamkati zamachubu opanda msoko:

1. Kuwonongeka kwa khungu la convex
Mawonekedwe a Macroscopic: Khoma lamkati la chubu lachitsulo lopanda msoko lagawaniza zolakwika zazing'ono zazitali zazitali, ndipo kutalika kwa zolakwika zazing'onozi ndi pafupifupi 0.2mm mpaka 1mm.
Mawonekedwe a Microscopic: Pali zophatikizika ngati unyolo wakuda-imvi kumchira, pakati ndi zozungulira chikopa chamkati mbali zonse za khoma lamkati la chitoliro chachitsulo chosasokonezeka.Mtundu uwu wa unyolo wakuda-imvi uli ndi aluminiyamu ya calcium ndi ma oxides osakanikirana (iron oxide, silicon oxide, magnesium oxide).

2. Chilema chowongoka
Mawonekedwe a macroscopic: Zowonongeka zamtundu wowongoka zimawonekera m'machubu achitsulo opanda msoko, okhala ndi kuya kwake ndi m'lifupi, ofanana ndi zokala.

Mawonekedwe a Microscopic: Zolemba pakhoma lamkati la gawo lapakati la chubu lachitsulo chosasunthika zili ngati poyambira ndikuya kwa 1 mpaka 2 cm.Oxidative decarburization sikuwoneka m'mphepete mwa poyambira.Minofu yozungulira ya poyambira ili ndi mawonekedwe azitsulo zachitsulo ndi mapindikidwe extrusion.Padzakhala ma microcracks chifukwa cha kukula kwa extrusion panthawi ya kukula.
