  今年初(chu)以来,水(shui)(shui)钢(gang)公司能(neng)源事业部按照(zhao)水(shui)(shui)钢(gang)精(jing)益TPM(全员(yuan)生(sheng)产维护)管理工作“2”阶段(duan)(操(cao)作标准化)要(yao)求,立足自(zi)(zi)身实(shi)际,紧(jin)紧(jin)围绕安全环(huan)保、节能(neng)减排、设备稳定顺行等(deng)焦点(dian)(dian)问题(ti),开展(zhan)了“降(jiang)低(di)01变电(dian)所配电(dian)室自(zi)(zi)耗电(dian)”“降(jiang)低(di)8号锅炉环(huan)保SO2折(zhe)算值(zhi)超标率”“降(jiang)低(di)混合站150号机油量消耗”“降(jiang)低(di)水(shui)(shui)钢(gang)外排水(shui)(shui)氨氮含量”“降(jiang)低(di)4号鼓风机主推温度”“优化制(zhi)氧工艺,提(ti)高制(zhi)氧机组氧产能(neng)”等(deng)精(jing)益TPM管理焦点(dian)(dian)课题(ti)攻关,并取(qu)得(de)明显效果。
  供电(dian)(dian)(dian)作(zuo)业区作(zuo)为水钢(gang)的(de)(de)输配电(dian)(dian)(dian)部门,配电(dian)(dian)(dian)室(shi)(shi)众多(duo),其中铁片区无人(ren)(ren)值守(shou)变(bian)电(dian)(dian)(dian)所有(you)5个,这些(xie)变(bian)电(dian)(dian)(dian)所的(de)(de)日常(chang)照明(ming)(ming)、除湿(shi)(shi)设(she)备(bei)(bei)等(deng)的(de)(de)用电(dian)(dian)(dian)时(shi)间(jian)(jian)得不(bu)到(dao)合理控制,导(dao)致使用效能(neng)低(di)。01变(bian)电(dian)(dian)(dian)所就(jiu)属于(yu)无人(ren)(ren)值守(shou)岗位,高、低(di)压变(bian)(配)电(dian)(dian)(dian)室(shi)(shi)有(you)除湿(shi)(shi)设(she)备(bei)(bei)、轴(zhou)(zhou)流(liu)风机、照明(ming)(ming)等(deng)用电(dian)(dian)(dian)设(she)备(bei)(bei),只有(you)这些(xie)设(she)备(bei)(bei)能(neng)根(gen)(gen)据实(shi)际情况运(yun)行(xing)才能(neng)更好地(di)保证(zheng)高、低(di)压电(dian)(dian)(dian)气设(she)备(bei)(bei)的(de)(de)稳定运(yun)行(xing),而因为无人(ren)(ren)值守(shou),要(yao)么是(shi)不(bu)能(neng)及(ji)时(shi)开启(qi)(qi)除湿(shi)(shi)、通风、照明(ming)(ming)设(she)备(bei)(bei),要(yao)么就(jiu)是(shi)除湿(shi)(shi)、通风、照明(ming)(ming)设(she)备(bei)(bei)长时(shi)间(jian)(jian)运(yun)行(xing)造(zao)成配电(dian)(dian)(dian)室(shi)(shi)自(zi)(zi)耗电(dian)(dian)(dian)增(zeng)大。为降低(di)变(bian)电(dian)(dian)(dian)所的(de)(de)自(zi)(zi)耗电(dian)(dian)(dian)量,该(gai)作(zuo)业区攻关团队从01变(bian)电(dian)(dian)(dian)所入手,新增(zeng)自(zi)(zi)动控制启(qi)(qi)停除湿(shi)(shi)设(she)备(bei)(bei)、轴(zhou)(zhou)流(liu)风机和(he)(he)具有(you)日常(chang)照明(ming)(ming)功能(neng)的(de)(de)设(she)施设(she)备(bei)(bei);安装(zhuang)温度控制器,有(you)效控制了轴(zhou)(zhou)流(liu)风机、室(shi)(shi)内(nei)(nei)空调和(he)(he)除湿(shi)(shi)机的(de)(de)启(qi)(qi)动时(shi)间(jian)(jian);加装(zhuang)配电(dian)(dian)(dian)室(shi)(shi)内(nei)(nei)、室(shi)(shi)外照明(ming)(ming)电(dian)(dian)(dian)源时(shi)间(jian)(jian)控制器,根(gen)(gen)据季节(jie)情况,对(dui)控制器设(she)定夜(ye)间(jian)(jian)运(yun)行(xing)时(shi)间(jian)(jian)范围,降低(di)了不(bu)必要(yao)的(de)(de)电(dian)(dian)(dian)能(neng)消耗。
  汽机(ji)(ji)作业(ye)(ye)区汽动鼓(gu)风(feng)站4号鼓(gu)风(feng)机(ji)(ji)从2020年6月起(qi)主(zhu)推(tui)温(wen)(wen)度(du)(du)就超过了(le)(le)机(ji)(ji)组(zu)(zu)温(wen)(wen)度(du)(du)报警值(zhi),并不断(duan)呈现(xian)上升(sheng)趋势,影响(xiang)机(ji)(ji)组(zu)(zu)设(she)备(bei)安全(quan)稳(wen)(wen)定运行(xing)(xing)(xing)。为降低(di)风(feng)机(ji)(ji)主(zhu)推(tui)温(wen)(wen)度(du)(du),达到(dao)3号高炉用风(feng)需求,该作业(ye)(ye)区成(cheng)立了(le)(le)专项课题(ti)小组(zu)(zu),对(dui)风(feng)机(ji)(ji)主(zhu)推(tui)温(wen)(wen)度(du)(du)过高的(de)现(xian)象和(he)危(wei)害进(jin)行(xing)(xing)(xing)分(fen)(fen)析(xi)讨论。该作业(ye)(ye)区的(de)小组(zu)(zu)成(cheng)员(yuan)在对(dui)现(xian)场、设(she)备(bei)、工艺(yi)进(jin)行(xing)(xing)(xing)实际调查分(fen)(fen)析(xi)后(hou),查找出导致(zhi)风(feng)机(ji)(ji)主(zhu)推(tui)温(wen)(wen)度(du)(du)异(yi)常升(sheng)高的(de)8个主(zhu)要原(yuan)因。接着,小组(zu)(zu)人员(yuan)针对(dui)症结进(jin)行(xing)(xing)(xing)攻关,使得(de)4号鼓(gu)风(feng)机(ji)(ji)主(zhu)推(tui)轴承温(wen)(wen)度(du)(du)在原(yuan)基础上降低(di)了(le)(le)10℃左右,今年初以来未(wei)发生过设(she)备(bei)故障,达到(dao)了(le)(le)安全(quan)稳(wen)(wen)定运行(xing)(xing)(xing)要求。
  此外,热力作业区降(jiang)低了(le)(le)混合站(zhan)150号机油(you)量消耗(hao),供(gong)水(shui)(shui)作业区降(jiang)低了(le)(le)水(shui)(shui)钢外排(pai)水(shui)(shui)氨氮含量,制(zhi)氧(yang)作业区优化了(le)(le)制(zhi)氧(yang)工(gong)艺并提(ti)高了(le)(le)制(zhi)氧(yang)机组氧(yang)产(chan)能……每一(yi)项成果都展示出了(le)(le)各作业区职工(gong)的聪明才智(zhi),他们从(cong)身边事(shi)入手,从(cong)制(zhi)约经(jing)营生产(chan)的关键点入手,工(gong)作现场和设(she)备性能均得到有效(xiao)改善,保证(zheng)了(le)(le)设(she)备的安(an)全运行(xing),助力了(le)(le)水(shui)(shui)钢公司经(jing)营生产(chan)工(gong)作。
