19、坯成本为3827.32元/吨钢，比6月份下降47.89元/吨钢，加工费为632.00元/吨钢，比6月份下降42.68元/吨钢。具体情况分析如下：1、钢铁料本月钢铁料成本3452.79元/吨钢，比6月份的3467.10元/吨钢下降14.31元/吨钢。下降的主要原因是铁水用量下降，冷料比提高。本月铁水成本3219.66元/吨，比上月降低56.29元/吨钢。其中：铁水平均价格3195.32元/吨钢，比6月份的3200.53元/吨钢降低5.21元/吨钢，导致成本降低5.32元/吨。本月铁水单耗1007.62Kg，比6月份1023.57Kg减少15.95Kg，导致成本下降50.97元/吨钢；本月冷料成本

20、233.12元/吨钢，比上月升高41.97元/吨钢。其中：冷料单耗81.06Kg，比6月份的64.77Kg增加16.29Kg，导致成本升高46.84元/吨钢。冷料平均价格2875.88元/吨钢，比6月份的2951.07元/吨钢降低75.19元，导致成本降低4.87元/吨钢。2、辅助材料本月辅料成本213.64元/吨钢，比6月份的245.89元/吨，降低32.25元/吨钢，其中：合金料：本月合金成本135.51元/吨，比6月份的166.69元/吨钢降低31.18元/吨钢，本月单耗17.61公斤，比6月份的19.88公斤降低2.27公斤，合金用量减少的原因主要是钢种构造不同造成。各钢种产量7月份所

21、占比例与6月份所占比例对照如下表：钢种7月产量所占比例6月产量所占比例7月与6月对比HRB33540.50%23.74%16.76%HRB335a0.00%8.89%-8.89%HRB40014.46%33.04%18.58%Q23543.79%33.92%9.87%Q345b1.25%0.00%1.25%HRB500a0.00%0.40%-0.40%耐材费本月耐材成本33.63元/吨钢，比6月份的36.98元/吨降低3.35元/吨钢。其他辅料：本月其他辅料单位成本44.50元/吨钢，比6月份的42.22元/吨钢低2.28元/吨钢。其中石灰消耗72.77公斤/吨钢，比6月份的62.17公斤/吨

22、钢上升10.60公斤/吨钢。原因主要有两个：一是本月铁水Si比上月上升0.06%，影响石灰消耗上升5.16公斤；二是石灰质量较上月有所下降，尤其是外购石灰质量较差，因石灰质量原因影响石灰消耗上升约3公斤。近两月铁水及石灰主要成分如下：月份铁水成分%SiMnSP6月0.560.230.020.107月0.620.270.020.107月比6月0.060.040.000.00月份外购石灰成分%SiO2CaO活性度灼减6月1.5085.392859.17月1.0084.4128110.67月比6月-0.5-0.98-41.5月份石灰窑石灰成分%SiO2CaO活性度灼减6月0.7388.243298.

23、457月0.7386.0531010.087月比6月0.00-2.19-191.633、燃料及动力本月单位成本83.91元，比6月份的62.73元/吨钢高21.18元/吨钢。主要原因是：本月转帐动力厂费用22.54元/吨钢，上月无动力厂费用；本月转帐二期制氧用电744万度，吨钢25.70元，上月转268万度，吨钢17.05元，本月比上月多转476万度电，吨钢16.15元。4、工资及五险两费一金本月工资及五险两费一金成本比6月份低4.36元/吨钢。5、制造费用本月制造费用吨钢成本58.59元，比6月份的70.02元/吨钢降低11.43元/吨钢。与6月份相比，费用减少较多的工程如下：折旧费比6月份

24、减少20.78万元，吨钢1.28元；机物料消耗比6月份减少110.96万元/吨钢，吨钢6.84元；修理费比6月份减少16.08万元/吨钢，吨钢0.99元；办公费、运输费等费用合计比6月份减少吨钢2.32元。二、7月份成本与“五个一百工程目标成本比照以“五个一百工程目标成本价格重新计算7月份各钢种成本与目标成本对比如下：1、Q235钢坯成本与目标成本比照 成本工程7月份Q235成本Q235目标成本7月与目标成本对比单价 单耗单位成本单价 单耗单位成本价格单耗单位成本一、原 材 料3436.263338.7397.541.钢铁料3147.371.095793448.863100.561.07908

33、多转17.58元/吨钢。扣除此费用，本月成本3730.57元/吨钢，比目标高95.28元/吨钢。吨钢加工费555.58元，比目标高48.95元。主要情况分析如下：钢铁料：本月钢铁料消耗1095.79公斤/吨钢，比目标1079.08公斤/吨钢高16.71公斤，吨钢成本3448.86元，比目标3345.76元高103.10元/吨。铁水：本月吨钢消耗1004.24公斤，比目标0.98064高23.60公斤，吨钢成本高120.36元/吨。目标成本钢铁料消耗中铁水消耗量是根据铁水硅0.50%，温度1350，出钢温度1680-1700测算，因外购铁水温度低7月份外购铁水温度最低的1161，最高的1285，平均1252度。，根据我厂铁水温度变动控制经历值，温度每降低10度约减少废钢用量5吨，按此计算共增加铁水消耗14.84Kg/t,使铁水消耗增加，未能完成980.95公斤的目标要求。目标外购铁水消耗为184.40公斤，占目标铁水总量的18.80%，本月实际外购铁水消耗326.46公斤，占本月铁水总量的32.51%，本月外购铁水用量比目标增加142
