Yuav pib lub tshuab ntsia thawv li cas (Part 2)

B. KEV PAB CUAM THIAB KEV UA HAUJ LWM
1. Kev cog qoob loo
Raws li kev lag luam kev tshawb fawb, thiab kev lag luam nplai ntawm cov ntsia hlau tsim, qhov ntsuas
Lub peev xwm ntawm cov nroj tsuag tau thov kom muaj 2,400 tonnes ntawm tus ntsia thawv ib xyoos twg.
Lub peev xwm tsim tau raug xaiv raws li 300 hnub ua haujlwm ib xyoos ib zaug, 3 hloov ntawm
yim teev ib hnub twg. Cov hnub so ntawm daim ntawv qhia hnub tseem tshuav rau kev tu thiab
kev saib xyuas.
2. Kev Pabcuam Ntau Lawm
Qhov kev pab cuam ntau lawm yog raws li lub sij hawm yuav tsum tau rau kev hloov ntawm feedstock,
kev ua haujlwm thiab khoom siv rau cov tshuab xaiv. Raws li kev siv peev txheej tau teeb tsa
raws li nram no:
- 75% ntawm cov nroj tsuag muaj peev xwm nyob rau xyoo 1st
- 85% ntawm cov peev txheej cog hauv xyoo thib ob
- 100% ntawm cov peev txheej cog hauv xyoo thib 3
IV. Cov khoom siv thiab cov khoom siv
A. Cov khoom siv raw
Cov khoom siv raw uas xav tau rau kev tsim cov ntsia hlau yog:-
1. Tsawg carbon steel hlau rau ob hom, thiab
2. Cov ntawv txias txias rau cov ntsia hlau ru tsev.
Piv txwv tias 12.5% ​​ntawm tag nrho cov khoom yuav yog cov ntsia hlau vov tsev, qhov yuav tsum tau ua txhua xyoo
cov ntaub ntawv nyoos no tau qhia hauv Table 4.1. Cov ntsia hlau vov tsev feem ntau yog galvanized rau
tiv thaiv corrosion. Cov khoom tiav yog ntim nrog ib daim ntawv nyuaj.

SUMMARY NTAWM ANNUAL CONSUMPTION RAU RAW THIAB AUXILARY
Cov khoom siv thiab tus nqi

B. UTILITIES
Kev lag luam dej ntawm 250 m3 thiab hluav taws xob ntawm 15000 kWh tau siv rau hauv cov nroj tsuag no
ib xyoo. Tag nrho cov nqi hluav taws xob kwv yees yog USD 335. Cov ntsiab lus uas yog
qhia hauv Table 4.2.

TSEEM CEEB NTAWM LUB CHAW UA HAUJ LWM NTAWM LUB SIJ HAWM
V. TECHNOLOGY THIAB ENGINEERING
A. TECHNOLOGY
1. Cov txheej txheem ntau lawm
Kev tsim cov ntsia hlau hla dhau cov kauj ruam hauv qab no.
- Pub cov hlau coil rau ntsia thawv ua tshuab
- Kev tsim cov hauv qab thiab sab saum toj ntawm tus ntsia thawv thiab txiav ntawm tus ntsia thawv ua
tshuab manufacturing ntawm lub taub hau ntsia hlau xaus ntawm no
- Kev tsim cov ntsia hlau taub hau ntawm lub tshuab ntxhua khaub ncaws
- Polishing ntawm lub taub hau
- Pub lub taub hau rau cov ntsia hlau ua tshuab
- Punching ntawm lub taub hau mus rau tus ntsia thawv thiab nias rau lub kaus zoo li
- Galvanizing

2. Qhov chaw ntawm Technology
Mus ntsib Ethiopian Iron thiab Steel foundary Factory, uas nyob hauv Addis AbabaAkaki; thiab sib tham nrog cov neeg ua haujlwm technical thiab xa mus rau cov kws tshaj lij
ntaub ntawv nws muaj peev xwm los sau cov ntaub ntawv rau lub tshuab.
B. ENGINEERING
1. Machinery thiab khoom siv
Cov npe ntawm cov tshuab thiab cov khoom siv uas xav tau rau kev tsim cov ntsia hlau tau muab rau hauv
Table 5.1. Tag nrho cov nqi ntawm cov tshuab thiab khoom siv yog kwv yees li ntawm USD 168700, tawm
ntawm uas USD 136000 yuav tsum tau nyob rau hauv txawv teb chaws txiaj.
Cov nroj tsuag xav tau ib qho tuaj tos- tsheb thauj mus los ntawm cov khoom tiav thiab rau chaw ua haujlwm
kev ua si. Tag nrho cov nqi tsheb yog kwv yees li ntawm USD 9350.
