Lub Hnub Qub Grace tau tsim kho ib yam khoom tshiab Ferroboron. Lub sijhawm ib nrab xyoo dhau los, Ferroborron tau khaws cov kev lag luam zoo.
erroboron yog ib qho sib xyaw ntawm boron thiab hlau. Hauv qab no yog cov lus qhia luv luv ntawm ferroboron yam ntxwv:
1. Raws li cov pa roj carbon ntsiab lus, ferroboron tuaj yeem faib ua cov pa roj carbon tsawg (C ≤ 0.05% - 0.1%, 9% - 25% B) thiab cov pa roj carbon nruab nrab (C% 2.5%, 4% - 19% B). Ferroboron yog lub zog deoxidizer thiab boron additive hauv steelmaking. Lub luag haujlwm tseem ceeb tshaj plaws ntawm boron hauv cov hlau yog hloov ntau ntau ntawm cov khoom sib xyaw nrog boron me me, thiab txhawm rau txhim kho cov neeg kho tshuab zog, txias hloov pauv khoom, vuam khoom thiab cov khoom kub.
2. Ntxiv 0.07% B rau cov hlau tuaj yeem txhim kho qhov ua kom tawv tawv ntawm cov hlau. Txuas ntxiv ntawm boron rau 18% Cr thiab 8% Ni stainless hlau tuaj yeem ua kom nag lossis daus tawv thiab txhim kho qhov kub thiab txias zog thiab tawv. Hauv cov hlau cam khwb cia, boron yuav cuam tshuam rau graphitization, yog li nce qhov tob ntawm lub qhov ncauj dawb los ua nws nyuaj thiab hnav-resistant. Ntxiv 0.001% - 0.005% boron rau malleable cam khwb cia hlau yog qhov zoo los tsim nodular graphite thiab txhim kho nws txoj kev xa khoom. Tam sim no, cov txhuas qis thiab qis carbon ferroboron yog cov khoom tseem ceeb ntawm cov tshuaj amorphous alloys.
3. Mas siv hauv cov hlau thiab cam khwb cia hlau. Rau cov txheej txheem alloy hlau, caij nplooj ntoos hlav steel, tsis tshua muaj lub siab loj lub zog steel, tshav kub-resistant hlau, stainless hlau, thiab lwm yam Boron tuaj yeem txhim kho qhov tawv thiab hnav tsis kam hauv cov hlau nrum, thiab yog dav siv hauv tsheb, tsheb laij teb thiab tshuab cuab tam kev tsim khoom.
