Tsev Khoom 5-20mm Kub Rolled Steel Sheet nyob rau hauv Coil Shipbuilding Carbon Steel Phaj Sheet Chev

Lus piav qhia luv luv:

Kub dov steel kaujhais txog kev nias ntawm billets rau hauv qhov xav tau tuab ntawm cov hlau ntawm qhov kub thiab txias. Kub dov yog txheej txheem ntawm dov cov hlau ntawm qhov kub thiab txias, uas yog siab tshaj qhov kub ntawm recrystallization ntawm cov khoom. Qhov saum npoo ntawm cov ntawv kub dov yuav raug oxidized vim qhov saum npoo yuav ntxhib thiab nplaum rau hauv yob; Kub dov coils feem ntau muaj qhov loj me me thiab tsis tshua muaj zog thiab tawv, yog siv rau kev tsim steel, cov khoom siv rau kev tsim khoom, cov kav hlau thiab cov thawv.

Txheej txheem ntau lawm

Billet processing: Cov khoom siv raw yog qhov nruam nruam ingot los yog tawg. Cov ingots yog rhuab mus rau ib tug plastically deformable kub nyob rau hauv thaj tsam ntawm 1100-1250 ° C nyob rau hauv lub cub tawg tom qab kev soj ntsuam, thiab thaum lub ingots ncav cuag qhov kub thiab txias rau yas deformation.

Roughing: Cov radiant-heated ingots yog dov nyob rau hauv lub roughing zeb nrog ib tug series ntawm passes (feem ntau 3-7) coj lub thickness ntawm 150-300 hli mus rau 20-50 hli. Qhov dav kuj raug txo kom tsim tau ib qho nruab nrab bar.

Ua tiav: Tom qab dephosphorization (kom tshem tawm cov nplai oxide saum npoo), qhov nruab nrab bar yog nkag mus rau hauv lub tshuab tiav rau kev kub kub ntxiv (nyob ib ncig ntawm 5-7 hla), txo cov thickness ntxiv rau 1.2-25.4 hli (raws li cov khoom specification). Lub dov kub thiab ceev yog tswj kom tau raws li qhov xav tau grain refinement thiab mechanical zog.

Coiling: Thaum ua tiav ntawm kev ua tiav tiav, lub sawb yog coiled ntawm kev kub ceev mus rau qhov kub thiab txias (feem ntau ntawm 500 thiab 700 ° C) siv lub laminar txias system. Lub sawb yog ces coiled los ntawm lub coiler, ces cov txheej txheem kub dov coil ua tiav.

Kev sim ua: Cov coils ua tiav yuav raug kuaj xyuas qhov loj me, ntsuas cov khoom siv kho tshuab, thiab kuaj xyuas qhov zoo. Raws li kev tsim nyog lawv tau ntim, sau npe thiab thaum kawg khaws lossis xa tawm.
