Alloy Cored Hlau

Lub cored hlau yog ua los ntawm cov hlau nplaum zoo li lub sawb qhwv nrog hmoov hlau alloy. Raws li qhov sib txawv ntawm cov hmoov txhuas, nws tuaj yeem muab faib ua: ntshiab calcium cored hlau, silicon calcium cored hlau, silicon manganese calcium hlau, silicon calcium barium hlau, barium aluminium hlau, aluminium calcium hlau, calcium hlau hlau thiab lwm yam.

Hauv kev lag luam melting, qhov zoo ntawm cov hlau molten yog txhim kho los ntawm kev pub cov hlau molten rau hauv cov hlau cored.

Cov hlau cored tuaj yeem ua tau zoo dua ntxiv cov ntaub ntawv smelting rau hauv cov hlau molten lossis molten hlau hauv cov txheej txheem ntawm steelmaking lossis casting, zoo zam cov tshuaj tiv thaiv nrog huab cua thiab slag, thiab txhim kho tus nqi nqus ntawm cov khoom smelting.

Dav siv los ua deoxidizer, desulfurizer, thiab alloy additive, nws tuaj yeem hloov cov duab ntawm molten steel inclusions thiab zoo txhim kho qhov zoo ntawm steelmaking thiab casting khoom.

Calcium hlau cored hlau:

Calcium hlau cored hlau yog ib txoj kev ntawm deoxidizing molten steel hauv steelmaking, haum rau steelmaking qhauj. Calcium hlau cored hlau yog cov khoom siv tseem ceeb ntawm kev sib xyaw ntawm 30-35% hlau calcium hais thiab hlau hmoov. Lub sawb hlau yog qhwv los ua calcium hlau cored hlau.

Qhov zoo ntawm calcium-hlau cored hlau: Nws yog tsim rau refining molten steel, yuav tshem tawm cov residual oxygen thiab inclusions nyob rau hauv molten steel, muaj zoo fluidity ntawm molten steel, thiab yuav txo tau cov nqi refining.

High calcium cored hlau:

(1) Siv high-calcium cored hlau rau kev kho calcium nyob rau hauv zus tau tej cov roj carbon tsawg thiab tsawg-silicon steel yuav txo tau qhov kub thiab txias poob los ntawm 2.6 ° C nyob rau nruab nrab, txo cov silicon nce los ntawm 0.001%, txo lub sij hawm noj hlau los ntawm 1 feeb, thiab nce cov txiaj ntsig los ntawm 2.29 npaug piv nrog cov hlau-calcium hlau.

(2) Kev pub mis ntawm cov hlau-calcium hlau yog 3 npaug ntawm cov hlau calcium uas siab. Yog tias nws hloov mus rau hauv tib cov ntsiab lus calcium rau kev sib piv, kev pub mis ntawm cov hlau-calcium hlau yog 2.45 npaug ntawm cov calcium hlau.

(3) High-calcium cored hlau yog siv los ua cov hlau molten, thiab cov qib ntawm kev suav nrog hauv cov hlau yog sib npaug rau cov khoom noj hlau-calcium hlau, uas tuaj yeem ua tau raws li cov khoom xav tau.

Calcium silicon cored hlau:

Cov khoom siv tseem ceeb rau kev tsim cov CaSi Cored Hlau yog Calcium Silicon alloy. Cov crushed calcium silicon hmoov yog siv los ua cov khoom tseem ceeb, thiab cov tawv nqaij sab nrauv yog txias-kuav los tiag steel sawb. Nws yog nias los ntawm ib tug kws crimping tshuab los ua silicon-calcium cored hlau. Nyob rau hauv tus txheej txheem, lub steel sheath yuav tsum tau nruj nreem packed kom cov tub ntxhais cov ntaub ntawv sau tusyees thiab tsis muaj to.

Carbon cored hlau:

Carbon cored hlau yog siv rau lub hom phiaj ntawm cov pa roj carbon ntau nyob rau hauv steelmaking, thiab yog siv rau fine-tuning cov pa roj carbon ntsiab lus ntawm molten steel, uas yog zoo rau kev tswj cov pa roj carbon ntsiab lus nyob rau hauv molten steel thiab yuav txo tau cov nqi ntau lawm.

Cov yam ntxwv ntawm carbon hlau:
1. Cov txiaj ntsig ntawm cov pa roj carbon ntau dua 90%, thiab nws ruaj khov.
2. Txo cov nqi tsim khoom, uas yog qis dua tus nqi ntawm cov toner cored hlau tam sim no.
3. Lub sij hawm cia khoom yog txuas ntxiv.

Alloy cored hlau yog tsim rau deoxidation thiab desulfurization hauv steelmaking. Nws tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau, txhim kho plasticity, cuam tshuam toughness thiab fluidity ntawm molten steel. Nws kuj muaj cov yam ntxwv ntawm ncaj qha nkag mus rau molten steel rau melting thiab uniform tis tion.
