Sebopeho sa Lik'hemik'hale
Q235D carbon steel plate, matla a phahameng a tšepe e sebelisoa haholo kahong, koloi, kaho ea likepe, mechine le lisebelisoa le liindasteri tse ling tse ngata, empa poleiti ea tšepe e matla haholo e tlameha ho khethoa ka nepo. Pele ho tsohle, kereiti e phahame haholo, ho bolelang hore theko e tla ba holimo ka lebaka la litšenyehelo tse phahameng tsa tlhahiso. Taba ea bobeli, boemo bo tlase bo bolela hore ts'ebetso ea ts'ireletso ha e fihlelle maemo. Ntlha ea boraro, litlhaloso tsa lipoleiti tsa tšepe tse matla a phahameng li tlameha ho khethoa ka ho feletseng ho latela litšoantšo tsa moralo. Ntlha ea bone, ho kgothaletswa ho reka lisebelisoa tse khethehileng tsa khoebo ho hlahloba lipoleiti tsa tšepe tse matla haholo.

E na le boima bo botle. Ka ho laola ka thata sebopeho sa lik'hemik'hale, ho fokotsa litaba tsa lintho tse kotsi ka poleiti ea tšepe ea Q235D, le ho khetha maemo a loketseng a kalafo ea mocheso, poleiti ea tšepe ea NM360 e na le boima bo botle. Ka hona, likarolo tsa mohaho tse ka tšeptjoang ka ho fetisisa li ka hahoa ho ea ka ho hlōleha ha brittle ha likarolo tse sa tsitsang. Q235D carbon steel plate e nka theknoloji e tsoetseng pele le lisebelisoa, li kopantsoe le tsamaiso e phahameng le ea saense ea botekgeniki, e le hore thepa le sebōpeho sa sehlahisoa li tšoane ebile li ntle.
S355J2 tšepe plate Q235D carbon steel rolling process ke mokhoa o laoloang. Nakong ea ho phutha, mocheso oa ingot ke 1000-1050 ° C; Mokhahlelo oa pele o nka mokhoa o fokolang oa ho fokotsa lebelo le leholo, boemo ba mocheso o phahameng ke 950-1000 ° C, lebelo la ho phalla ke 1.6-2.0m / s, sekhahla se le seng sa phokotso ea Q235D carbon steel plate ke 15-20%, 'me sekhahla sa phokotso ea kakaretso ke 40-45% ho netefatsa deformation e felletseng ea ingot. Mokhahlelong oa pele, mocheso oa ho qala ke 910-930 ° C, 'me mocheso oa ho qetela ke ≤ 870 °C.
