Calcium silicon hmoov cored hlau (casi cored hlau) yog cov khoom siv tseem ceeb hauv lub ladle refining teb ntawm steel metallurgy. Nws muaj densely encapsulating precisely proportionedcalcium silicon hmoovnyob rau hauv ib tug tsawg- carbon steel sawb, ces txhaj nws mus rau hauv lub molten hlau ntawm ib tug tswj ceev thiab qhov tob uas siv ib tug hlau feeder. Qhov no ua tiav kev ua kom huv si sib sib zog nqus ntawm cov hlau molten, tswj kev suav nrog morphology, thiab micro-alloying ntawm cov khoom. This revolutionary process solves the global challenge of incorporating and efficiently utilizing calcium metal due to its low density and boiling point, providing a core technological guarantee for the production of high-purity, high-performance special steels.

Tsis zoo li cov tsoos hlau thaiv ntxiv los yog tshuab cov txheej txheem, tus nqi tseem ceeb ntawm calcium silicon cored hlau nyob rau hauv nws cov precision, efficiency, thiab repeatability. Nws nce cov calcium kev kho mob tawm los ntawm tsawg dua 10% mus rau qhov ruaj khov thiab tswj tau 15% -35%, ua rau nws txoj kev xaiv zoo rau cov tuam txhab steel niaj hnub los txhim kho cov khoom zoo thiab kov yeej cov fwj dej zoo.

FAQ

Q: Yuav ua li cas txhawm rau txhim kho calcium rov qab hauv cov txheej txheem pub mis?

A:Tus nqi rov qab yog ib qho kev xav txog ntawm theem txheej txheem. Raws li peb qhov kev paub dhau los, peb xav kom tsom mus rau peb lub ntsiab lus: 1) Lub Sijhawm: Xyuas kom nws ua tiav tom qab txaus deoxidation thiab desulfurization;

2) Qhov tob: Cov hlau pub qhov tob yuav tsum ncav cuag 1/2 mus rau 2/3 ntawm lub taub hau hydrostatic ntawm cov hlau molten kom tsis txhob poob qis;

3) stirring: Siv qhov tsim nyog hauv qab- tshuab argon nplawm kom txhawb kev sib cais tsis sib xws yam tsis muaj ntau dhau. Peb tuaj yeem muab rau ntawm -cov txheej txheem tshawb xyuas qhov chaw los pab cov neeg siv khoom kom zoo dua lawv cov tshuab.

Q: Yuav ua li cas xaiv cov calcium cov ntsiab lus ntawm cored hlau raws li qib steel?

A: This reflects the professionalism of precise matching. For ultra-low carbon steel and electrical steel, we recommend using high-calcium (>30%) xaim los qhia calcium zoo hauv me me; rau siab - cov ntsiab lus sulfur lossis tuab tuab - ntu steel qib, siab -calcium hlau yuav tsum raug xaiv los xyuas kom meej nkag mus. Rau cov pa roj carbon monoxide-tua hlau, cov qauv hlau nrog cov ntsiab lus calcium ntawm 28%-30% txaus, muab cov nqi zoo dua. Peb pab neeg ua haujlwm tuaj yeem muab cov lus pom zoo rau koj.

Q: Rau kev tsim cov yeeb nkab steel (piv txwv li, X70, X80) yuav tsum tau nruj HIC tsis kam, lub hom phiaj kho tshwj xeeb twg peb yuav tsum tsom nrog CaSi hlau?
A: For HIC-resistant pipeline steels, the primary goal of calcium treatment is inclusion modification, not just desulfurization. You need to ensure that any remaining alumina (Al₂O₃) inclusions are fully transformed into liquid calcium aluminates. This requires sufficient calcium addition to achieve a specific calcium-to-aluminum ratio (often targeted as Ca/Al > 0.1) and ensuring the inclusions are modified before casting. Our high-calcium wire (e.g., Ca >30%) thiab cov lus pom zoo pub mis yog tsim los pab koj tsis tu ncua ntaus lub hom phiaj tseem ceeb no.
