Ib txwm75 ferrosilicon hlauFeem ntau muaj cov ntsiab lus txhuas ntawm 1% -2%, thaum peb cov khoom tswj hwm cov ntsiab lus txhuas rau plaub theem: 0.3%, 0.5%, 0.8%, thiab 1.0%. Qhov no yog vim hais tias txhuas cov ntaub ntawv alumina inclusions nyob rau hauv steel. Cov kev suav nrog no nyuaj thiab nkig, ua rau peb qhov teeb meem:

Stamping tawg:Qhov no yog qhov kev txhawj xeeb loj tshaj plaws rau cov neeg siv khoom ua automotive steel ntawv.

Txo qaug zog lub neej:Qhov no yog ib qho kev txhawj xeeb loj rau cov neeg muas zaub ua lub caij nplooj ntoos hlav steel thiab bearing steel.

Nruam casting nozzle blockage:Alumina tuaj yeem ua raws li phab ntsa sab hauv ntawm lub nozzle thaum lub sij hawm casting, ua rau muaj kev cuam tshuam kev cuam tshuam.

Yog li ntawd, yog tias koj tab tom tsim cov qib steel nrog cov kev xav tau siab purity (automotive steel sheets, hluav taws xob steel, caij nplooj ntoos hlav steel, bearing steel), koj yuav tsum siv.tsawg aluminium ferrosilicon. Thaum zoo tib yamferrosiliconyog pheej yig dua, tus nqi me me sib txawv tsis txaus los cuam tshuam cov nqi seem.

Peb faib cov qis al ferrosilicon rau plaub qib raws li cov ntsiab lus ntawm txhuas. Koj tuaj yeem tshawb xyuas koj cov qib steel cov kev cai txhuas kom pom cov qib tsim nyog:

Al 0.3:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.3%. Qhov no yog qib siab tshaj plaws, tshwj xeeb tshaj yog rau cov hlau hluav taws xob (silicon steel) thiab automotive IF steel. Hom hlau no tsis tshua muaj siab rau cov ntsiab lus txhuas; ntau tshaj 0.01% tuaj yeem ua rau nws siv tsis tau.

Al 0.5:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.5%. Cov qib no feem ntau yog siv los ntawm cov neeg siv khoom ua automotive DP steel, TRIP steel, thiab pipeline steel.

Al 0.8:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.8%. Qib no yog txaus rau cov neeg muas zaub ua lub caij nplooj ntoos hlav steel, bearing steel, thiab pwm steel.

Al 1.0:Cov ntsiab lus txhuas tsawg dua lossis sib npaug li 1.0%. Qib no yog siv los ntawm cov neeg siv khoom ua cov hlau zoo tib yam thiab cov hlau tsis tshua muaj hlau; nws yog huv dua li qub ferrosilicon thiab tsis kim heev.
