Makonda mawonekedwe chitoliro ndi kalasi Q345C/D/E ndi specail pamwamba mankhwala
1. Kufotokozera
chigawo dzenje zimagwiritsa ntchito zitsulo dongosolo ndi makampani makina, koma mawonekedwe yachibadwa ndi kalasi sangathe kukhutitsa malo ena apadera;
Kuti zigwirizane ndi zofunikira zambiri, kampani yathu ikukonzekera kupereka zopempha mwachangu motere:
1) mawonekedwe apadera ngati chubu cha Oval, chubu cha diamondi, chubu la buledi, chubu chooneka ngati chapadera
2) kalasi yatsopano ngati Q345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn etc.
3) Pamwamba ngati epoxy primer, kuwombera kuwombera etc
Q345A, Q345B, Q345C, Q345D, Q345E ndizosiyana zamakalasi apamwamba, zikuwonjezeka kuchokera ku A mpaka E, makamaka chifukwa cha kusiyana.
mu mphamvu kutentha chifukwa zili microelements monga phosphorous ndi sulfure, kutanthauza kutentha kwambiri ndi
osiyana Ndipo chubu mankhwala zikuchokera makina makina katundu.
Gulu la Q345A silimakhudza; kalasi ya Q345B ndi kugwedeza kwa madigiri 20 kutentha kwa chipinda; kalasi ya Q345C ndi 0 degree shock;
kalasi ya Q345D ndi -20 degree shock; kalasi ya Q345E ndi -40 degree shock. Pa kutentha kosiyanasiyana, mtengo wa kugwedezeka ulinso
zosiyana.
Mphamvu zokolola za Q sizichepera 345Mp. Gulu labwino likuwonetsa kuchuluka kwa zinthu zonyansa (carbon, manganese, silicon, sulfure,
phosphorous. Ndi chinthu chodetsedwa muzitsulo), ndipo A, B, C, ndi D amapita, ndiye kuti zonyansazo zimachepa.
2. Gulu la Chemical Composition
| Gulu | Kupanga Kwamankhwala (%) | ||||
| C | Si | Mn | P | S | |
| Q235B | ≤0.20 | ≤0.35 | ≤1.40 | ≤0.045 | ≤0.045 |
| Q345B | ≤0.20 | ≤0.50 | ≤1.70 | ≤0.035 | ≤0.035 |

| Q345D | ≤0.18 | ≤0.50 | ≤1.70 | ≤0.035 | ≤0.025 |
3. Katundu Wamakina
| Gulu | Mechanical Property | ||
| Mphamvu Zokolola (N/mm2)/(Mpa) | Kulimba Kwamphamvu (N/mm2)/(Mpa) | Kutalika (%) | |
| Q235B | ≥235 | 370-500 | ≥26 |
| Q345B | 345 | 470-630 | ≥20 |
| Q345C | 345 | 470-630 | ≥21 |
| Q345D | 345 | 470-630 | ≥21 |
4. Chithandizo chapamwamba:
Epoxy zinc primer

5. Q345 C/D/E ntchito:
1) Q345C opanda chitoliro chitoliro zimagwiritsa ntchito mabungwe makina, zida hayidiroliki, chimagwiritsidwa ntchito mankhwala, mafuta, nsalu,
mankhwala, chakudya, makina ndi mafakitale ena, makamaka ntchito mafakitale zosagwira mapaipi, mbali structural ndi mbali.
2) Q345D chitoliro chachitsulo chosasunthika chimagwiritsidwa ntchito makamaka mu zombo, ma boilers, zotengera zokakamiza, akasinja osungira mafuta, milatho, zida zamagetsi,
makina onyamulira ndi mayendedwe ndi zida zina zowotcherera kwambiri.
3) Q345E machubu cryogenic ntchito kuthamanga kwambiri ndi kutentha mapaipi ndi zipangizo monga zomera mphamvu,
makina opangira magetsi a nyukiliya, ma boilers othamanga kwambiri, ma superheaters okwera kwambiri komanso otenthetsera. Q345E cryogenic chubu ili ndi
gawo lopanda kanthu ndipo amagwiritsidwa ntchito kwambiri ngati payipi yonyamula madzi, monga mapaipi otengera mafuta, gasi, gasi, madzi.
ndi zinthu zina zolimba.
6. Magawo Ena makonda:
5. Q345 C/D/E ntchito:
Q345D chitoliro chopanda chitsulo, Q345D chitoliro chopanda msoko, chitoliro chachitsulo cha Q345D, chitoliro chachitsulo cha Q345E, chitoliro chopanda chitsulo chokwera
Kupanikizika feteleza zida, otsika kutentha zitsulo chitoliro kwa zomera mphamvu, zomera mankhwala ndi boilers.
