Raws li cov chaw tsim khoom suav ntseeg ntseeg tau tshwj xeeb hauv cov pa roj carbon dub, peb xa cov khoom siab tshaj -kev ua tau zoo raws li kev xav tau thoob ntiaj teb.
Peb cov pa roj carbon dub dub khav theeb ua haujlwm tau zoo, txhim khu kev txhim kho lub zog, thiab tus nqi sib tw, ua rau lawv mus - rau kev xaiv rau kev lag luam thoob plaws kev tsim kho, tsheb, tshuab, thiab kev tsim khoom.
1. Raw Khoom Npaj & Smelting
Xaiv high-purity hlau ore, seem hlau thiab coke ua raw khoom. Cov ntsiab lus carbon yog nruj me ntsis tswj ntawm 0.12% thiab 0.20% kom ua tau raws li cov qauv ntawm GB / T 700 thiab ASTM A36.
Cov ntaub ntawv nyoos raug tshuaj xyuas rau purity thiab muaj pes tsawg leeg ua ntej nkag mus rau hauv qhov cub tawg / hloov pauv rau smelting, tshem tawm cov impurities xws li sulfur thiab phosphorus los xyuas kom meej qhov kev ua tau zoo ntawm cov khoom tiav.
2. Nruam Casting & Forming
Lub smelted molten steel yog poured rau hauv ib tug nruam casting tshuab, txias thiab solidified rau hauv slabs. Lub casting ceev thiab txias npaum li cas yog nruj me ntsis tswj los xyuas kom meej cov qauv nyob rau hauv lub slabs, tsis muaj shrinkage qhov los yog tawg, thiab lub thickness ntawm cov slabs yog tswj ntawm 3 hli thiab 50 hli.
3. Cua sov & Kub Rolling
Cov slabs raug xa mus rau lub qhov cub hluav taws xob taug kev thiab cua sov rau 1150-1250℃. Tom qab descaling nrog high-pressure dej, lawv tau dov los ntawm ntau dhau ntawm kub dov mills los ua steel daim hlau ntawm txawv thicknesses thiab dav (dav: 1000mm-2000mm, ntev: 2000mm-12000mm).
4. Txias & Dub nto tsim
Cov hlau kub- dov steel phaj yog txias los ntawm laminar ntws kom tsis txhob deformation. Thaum lub sij hawm txias txias, ib daim tawv dub oxide zaj duab xis (dub tawv nqaij) yog tsim rau ntawm qhov chaw, uas txhim kho corrosion kuj thiab tsis tas yuav tsum tau pleev xim ntxiv.
5. Tiav & Dimensional Txiav
Cov hlau txias txias yog ncaj nraim kom tshem tawm warpage, thiab tom qab ntawd txiav raws li cov neeg siv khoom xav tau (customizable size). Lub txiav precision yog tswj nyob rau hauv ± 0.5mm los xyuas kom meej tias qhov luaj li cas raws li cov kev xav tau ntawm kev tsim kho, tsheb thiab lwm yam teb.
6. Kev soj ntsuam zoo
100% tsis yog-kev kuaj kev puas tsuaj (ultrasonic, magnetic particle test) yog ua los ntawm cov hlau phaj tiav, thiab cov khoom siv kho tshuab (lub zog tensile 345MPa-420MPa, elongation ntau dua lossis sib npaug li 20%) raug kuaj xyuas kom ntseeg tau tias txhua pawg ua tau raws li cov qauv zoo.
7. Anti-Tshuaj xeb & ntim rau kev xa khoom
Cov ntawv hlau tsim nyog tau txau nrog cov tshuaj tiv thaiv- xeb, tom qab ntawd kho nrog cov hlua hlau thiab ntim nrog cov dej noo- pov thawj zaj duab xis. Lawv raug thauj mus rau hauv cov thawv lossis cov nkoj loj raws li qhov kev txiav txim kom muaj nuj nqis, npaj rau kev xa khoom thoob ntiaj teb.
