c. 計算過程: =0.20+0.40
(注意:配料總重
量為四種配料重
量之和)
=50x3.4/100+50x0.9/100+1x90/100
=1.70+0.45+0.90
=3.05
|Si=50x2.3/100+50x1.0/100+1x80/100
=1.15+0.50+0.80
=2.45
Mnı=50x0.4/100+50x0.8/100
c. 計算過程: =0.20+0.40
(注意:配料總重
量為四種配料重
量之和)
=0.60
С2=3.05(1+0.15)=3.508
Si2=2.45(1-0.10)=2.205
Mn2=0.60(1-0.15)=0.510
C=3.508x100/102=3.439=3.44%
Si=2.205x100/102=2.162=2.16%
Mn=0.510x100/102=0.500=0.50%
CE=3.439+1/3(2.162)=4.160=4.16%
