1、石灰加入量的计算 shjrl,吨钢石灰加入量=;

double shjrl;

jszrl = double.

Parse(txtTs.Text.ToString()) + double.Parse(txtTk.Text.ToString());

金属装入量(吨)=铁水的重量+铁块的重量;

si = (double.Parse(txtTsSi.Text.ToString()) * double.Parse(txtTs.Text.ToString()) + double.Parse(txtTkSi.Text.ToString()) * double.Parse(txtTk.Text.ToString())) / jszrl;

p = (double.Parse(txtTsP.Text.ToString()) * double.Parse(txtTs.Text.ToString()) + double.Parse(txtTkP.Text.ToString()) * double.Parse(txtTk.Text.ToString())) / jszrl;

r = double.Parse(txtR.Text.ToString());

if (p = 0.4 && si < 0.6) { pjss = 0.011;

} else if (si >= 0.6 && si < 0.9) { pjss = 0.013;

} else if (si >= 0.9) { pjss = 0.016;

} //设定渣中FeO的质量百分比为18%;

渣中金属铁粒的损失占渣量的8%;

//jsss,金属损失=渣中FeO的金属量+渣中铁粒损失+喷溅损失,单位:吨;

double jsss;

jsss = gzzl * 0.18 *

56 /

72 + gzzl * 0.08 + pjss;

金属损失(吨)=渣中FeO的金属量+渣中铁粒损失+喷溅损失;

//将金属损失按铁水和铁块比例分开计算成本的影响 钢铁料成本=铁水带入Si量%*铁水单价+铁块带入Si量%*铁块单价 //gtlcb,钢铁料成本=铁水带入Si量%*铁水单价+铁块带入Si量%*铁块单价;

double gtlcb = jsss * double.Parse(txtTs.Text.ToString()) * double.Parse(txtTsSi.Text.ToString()) / jszrl / si * double.Parse(txtTsdj.Text.ToString()) + jsss * double.Parse(txtTk.Text.ToString()) * double.Parse(txtTkSi.Text.ToString()) / jszrl / si * double.Parse(txtTkdj.Text.ToString());

钢铁料成本=吨钢消耗铁块Si的成本+吨钢消耗铁块S的成本;

//shcb,石灰成本=石灰单价*石灰加入量;

double shcb = double.Parse(txtShdj.Text.ToString()) * shihui / 1000;

//Sicb,Si对成本的影响=钢铁料成本+石灰成本;

double Sicb = (gtlcb + shcb) * double.Parse(txtTk.Text.ToString()) / jszrl;

//shs,S对石灰的影响;

出钢时炉中S要小于.030%;

//设定:脱S效率按20%计算;

//s,金属料中总的S含量;

Tksyx,铁块S对成本的影响;

double s = (double.Parse(txtTs.Text.ToString()) * double.Parse(txtTss.Text.ToString()) + double.Parse(txtTk.Text.ToString()) * double.Parse(txtTks.Text.ToString())) / jszrl;

double Tksyx = 0;

if (s * 0.8 > 0.030) { //吨钢成本 (shcb石灰成本+ gtlcb钢铁料成本) //脱去一个S需要不考虑S时总渣量的5%的渣量,增加5%的渣量消耗的石灰成本和钢铁料成本就是S的影响成本 Tksyx = (s - 0.030) *

50 * (shcb + gtlcb);

Tksyx = Tksyx * double.Parse(txtTk.Text.ToString()) / jszrl;

}

3、合金成本分析 //合金加入量计算 //Sijrl,硅铁加入量;

Mnjrl,锰硅加入量 double Sijrl, Mnjrl;

//锰硅加入量 Mnjrl = (double.Parse(txtMnzx.Text.ToString()) - double.Parse(txtYuMn.Text.ToString())) / double.Parse(txtHjMn.Text.ToString()) / double.Parse(txtMnxsl.Text.ToString()) * 100000;

txtMnjrl.Text = Mnjrl.ToString().Substring(0, 5);

//硅铁加入量;

锰硅合金增硅量,Zsi;

double Zsi = Mnjrl * double.Parse(txtHjMnSi.Text.ToString()) /

100 * double.Parse(txtSixsl.Text.ToString()) / 1000;

Sijrl = (double.Parse(txtSizx.Text.ToString()) - Zsi) / double.Parse(txtHjSi.Text.ToString()) / double.Parse(txtSixsl.Text.ToString()) * 100000;

txtSijrl.Text = Sijrl.ToString().Substring(0, 4);

//计算合金成分对吨钢成本的影响 //Mnyx,硅锰合金的影响;

Siyx,硅铁成分的影响;

double Mnyx = Mnjrl * double.Parse(txtGmdj.Text.ToString()) / 1000;

double Siyx = Sijrl * double.Parse(txtGtdj.Text.ToString()) / 1000;
