Phindu kusanthula mosalekeza kuponyera billet zipangizo Kutentha:

Pogwiritsa ntchito njira yogubuduza mwachindunji (tengani chitsanzo cha matani 1 miliyoni pachaka), zopindulitsa zosiyanasiyana zomwe zimapangidwa:

1. Kugwiritsa ntchito mphamvu ndi kuchepetsa umuna wa ng’anjo yotentha

Kwa mphero wamba wa billet ndi waya, kugwiritsa ntchito mphamvu pa tani imodzi ya chitsulo kumakhala pafupifupi 650kWh, yomwe pafupifupi 520kWh imagwiritsidwa ntchito kutenthetsa billet mpaka 1150 ° C, pomwe kugwiritsa ntchito mphamvu pakugubuduza ndi 110kWh yokha. Komabe, kutentha kwenikweni kwa thupi pa tani imodzi ya billet pa kutentha kumeneku ndi 230kWh yokha, ndipo kutayika kwa kutentha kosiyanasiyana monga kutentha kwa ng’anjo yotentha kupitirira 50%. Chifukwa chake, kugubuduza molunjika popanda kutentha kumatha kupulumutsa mafuta ndikuchepetsa kugwiritsa ntchito mphamvu.

Popitiriza kuponyera zida zotenthetsera za billet zomwe zimagwiritsa ntchito malasha ngati mafuta, ngakhale popereka mosalekeza kutulutsa kotentha kwa billet, pafupifupi kugwiritsa ntchito malasha pang’anjo yotentha ndi chitsulo cha 45kg/t. Kuchotsedwa kwa njira yowotchera ng’anjo kumatha kupulumutsa pafupifupi matani 45,000 a malasha wamba chaka chilichonse, zomwe zikutanthauza kuchepetsedwa kwa matani 117,000 a mpweya wa carbon, matani 382.5 a sulfure dioxide, ndi matani 333 a nitrogen oxides.

Mtengo wa malasha ndi 1,000 yuan/t, ndipo kuthetsa kutentha ndi kugwiritsa ntchito kugudubuza mwachindunji kungapulumutse 45 yuan pa tani yachitsulo, yomwe ingapulumutse yuan 45 miliyoni pachaka.

Kwa ng’anjo yowotchera pogwiritsa ntchito gasi wowotchera ngati mafuta, ngakhale popereka mosalekeza kutulutsa kotentha kwa billet, pafupifupi mpweya wogwiritsa ntchito ng’anjo yotentha ndi 250m3/t chitsulo. Njira yowotchera ng’anjo imathetsedwa ndipo mpweya wophulika wa ng’anjo umagwiritsidwa ntchito popanga mphamvu. Malingana ndi 3.5m3 kuphulika kwa ng’anjo yamoto, 1 kilowatt-ola la magetsi likhoza kupangidwa, ndipo tani yachitsulo ikhoza kusinthidwa kukhala 71.4kwh. Malinga ndi kuwerengera kwa mphamvu yopangira mphamvu ya 0.5 yuan / kwh pambuyo pochotsa zodzipangira zokha ndikugwiritsa ntchito, phindu la pachaka lamagetsi owonjezera ndi 35.71 miliyoni yuan.

2. Kuchepetsa kuyaka kwa okosijeni

Kugwiritsa ntchito kugubuduza mwachindunji kumapewa kutentha kwachiwiri kwa billet ndipo kumatha kuchepetsa kutayika kwa okosijeni ndi 0.6%. Mtengo wagawo ndi 2,000 yuan/t, womwe ungapulumutse yuan 12 miliyoni pachaka.

3. Kupitirizabe kuponyera moto kudula ndi kudula msoko kuchepetsa

Kugudubuzika kwachindunji kumatengedwa, ndipo billet yopitilirapo imasinthidwa kuchoka ku chodula cha tochi kupita ku shear ya hydraulic. Mtengo wogwiritsira ntchito gasi wodula nyali ndi pafupifupi 0.5 yuan / t, ndipo 12m iliyonse yodutsa billet ndi 5mm, chitsulo chofanana ndi 0.47kg/t. Malinga ndi kuwerengera kwa matani 1 miliyoni, ndikufanana ndi 1.44 miliyoni yuan pakuchepetsa kwapachaka mtengo wodula ndi kudula gasi.

4. Kutentha kwa ng’anjo ndi kuchepetsa ntchito

Kutulutsa kwapachaka kwa matani 1 miliyoni a ng’anjo yotenthetsera zitsulo ndizofanana ndi mtengo wokonza pachaka wa 750,000 yuan, ntchito imawononga yuan 1 miliyoni, ndipo kugwiritsa ntchito mphamvu zamakina a ng’anjo kumawononga 1.5 miliyoni. Pambuyo pa kuthetsedwa kwathunthu kwa ng’anjo yowotchera, ndalama zokonzera ndi ntchito zitha kuchepetsedwa ndi 3.25 miliyoni.

Kuphatikizira maubwino opitilirabe kuponyedwa kwa billet zida zogubuduza, kwa mzere wopanga zitsulo wamba ndi kugubuduza kupanga ndi kutulutsa kwapachaka kwa matani 1 miliyoni pogwiritsa ntchito gasi wang’anjo yamoto monga mafuta ndi kuwotcha kotentha komanso kutumiza ma billets mosalekeza, pambuyo pakuwotcha. ng’anjo imachotsedwa, kuponyedwa kosalekeza ndi kugudubuza kungagwiritsidwe ntchito. Zimabweretsa phindu la pachaka la yuan 52.4 miliyoni, ndipo malinga ndi momwe ntchito ikugwirira ntchito, kugwiritsa ntchito magetsi kwa zida zomwe zangowonjezeredwa kumene mosalekeza ndi zofanana ndi bedi lozizirira loyambirira, tebulo loyatsira chakudya chotentha, ndi crane yoyendayenda. Kutentha kochepa kwa billet yowongoka kumawonjezera mphamvu yogwiritsira ntchito kugudubuza ndi zitsulo za 10kwh / t, zomwe zimapangitsa kuti pakhale mphamvu zowonjezera pachaka za 6 miliyoni. Pambuyo pochotsa, phindu lonse lazachuma likadali 46.4 miliyoni yuan, zomwe ndi zochititsa chidwi kwambiri.
