Kunyalanyaza Katundu wa "Kupyolera-Kunenepa".
Ichi ndi chimodzi mwa zolakwika zomwe sizimayimilira-komanso zoopsa kwambiri-zolakwika pama projekiti a heavy structural steel. Ogula ambiri kunja kwa nyanja amaganiza kuti kalasi yachitsulo ikangolondola, zinthuzo ndizoyenera kupanga.
Koma pamafakitale olemera omwe amagwiritsa ntchito mbale zachitsulo zokhuthala, lingalirolo litha kukhala chiwopsezo chachikulu chaumisiri. Zitsulo zokhazikika zokhazikika sizingakhale zokwanira, makamaka pama projekiti okhudza:
- Zomera zamafakitale zolemera
- Malo opangira magetsi
- Zida za Petrochemical
- Nyumba zamigodi
- Nyumba zazikulu{{0}zazitsulo
- Zomanga za m'mphepete mwa nyanja
- Zokwera-zapamwamba kwambiri
Vuto Lobisika Mkati Mwa Mbale Zachitsulo Zokhuthala
Pazinthu zolemera kwambiri-maka ma plates thicker than 20mm, 40mm, or even 100mm{4}zinthu zamkati zachitsulo zimakhala zofunika kwambiri.
Ogula ambiri amangoganizira za mphamvu zokolola, mphamvu zolimba, komanso mtundu wa pamwamba. Koma amanyalanyaza chinthu chofunikira:kudzera-kuchuluka kwake, amadziwikanso kutiZ-zolowera. Izi zimatsimikizira momwe chitsulo chimakhalira pansi pa kupsinjika kupyolera mu makulidwe a mbale panthawi yowotcherera ndi kunyamula.

Kodi Kuphulika kwa Lamellar N'chiyani?
Kung'ambika kwa Lamellar ndi cholakwika chobisika chomwe chimapezeka mkati mwa mbale zachitsulo. Nthawi zambiri zimayamba pamene kuwotcherera kolemera kumachepa, chitsulo chimakhala chosalimba chifukwa cha-kukhuthala kwa makulidwe, ndipo m'mbale mulibe-zopanda zitsulo.
Mng'aluwu umapanga mkati ndikufalikira mofananira ndi pamwamba pa mbale. Izi ndizofala kwambiri mu:
T-zolowa
Zolumikizira pamakona
Zipilala zamabokosi zokhuthala
Malo oletsa kuwotcherera kwambiri
Gawo lowopsa ndikuti kung'amba kwa lamellar sikungawonekere nthawi yomweyo kuchokera kunja. Koma mkati, kapangidwe kake kakhoza kale kusokonezedwa.
Chifukwa Chake Heavy Industrial Projects Ali Pangozi-Zowopsa
M'mafakitale akuluakulu azitsulo, zolumikizira zowotcherera nthawi zambiri zimanyamula katundu wambiri. Zitsanzo zikuphatikizapo crane-zothandizira mizati, nsanja za zida zolemera, zitsulo zopangira zitsulo, mafelemu opangira magetsi, ndi ma module akunyanja.
Mapulojekitiwa nthawi zambiri amagwiritsa ntchito mbale zokhuthala, -zowotcherera zingapo, kutentha kwambiri, ndi zowotcherera kwambiri. Popanda -kukhuthala koyenera, mphamvu zowotcherera zimatha kupitilira mphamvu yachitsulo yamkati. Zotsatira zake zitha kukhala kusweka kwamkati, kulephera kwa weld, kufooka kwamapangidwe, ndikuchepetsa moyo wotopa. Muzochitika zovuta kwambiri, kulephera kwakukulu kwapangidwe kumatha kuchitika polojekiti ikayamba kugwira ntchito.
Mapulojekitiwa nthawi zambiri amagwiritsa ntchito mbale zokhuthala, -zowotcherera zingapo, kutentha kwambiri, ndi zowotcherera kwambiri.(Kuti mupeze chiwongolero chathunthu pakusankha magawo oyenera owotcherera pamizere yolemetsa, werengani kufananitsa kwathu kwa uinjiniya wa[CJP vs. PJP kuwotcherera muzitsulo zamapangidwe].)Popanda -kukhuthala koyenera, mphamvu yowotcherera imatha kupitilira mphamvu yachitsulo yamkati.
Chifukwa chiyani mbale zachitsulo zokhazikika sizingakhale zoyenera
Ma mbale wamba amayesedwa makamaka kuti akhale ndi mphamvu zolimba, zokolola, komanso kutalika.Nthawi zonse tsimikizirani zotsatira za mayesowa motsutsana ndi Zikalata Zoyeserera za Mill.Koma sikuti nthawi zonse amayesedwakuchepetsa dera la Z-njira, yomwe imayesa kusinthasintha kwachitsulo kupyolera mu makulidwe ake.
M'mbale zokhuthala, zosawoneka -zosanjikiza zitsulo zimakhala zosanjikiza panthawi yogubuduzika. Zigawo zamkati izi zimachepetsa kulimba kwachitsulo chifukwa cha-kukhuthala kwa makulidwe. Ichi ndichifukwa chake nyumba zowotcherera zolemera nthawi zambiri zimafunikira chitsulo cha Z15, chitsulo cha Z25, kapena chitsulo cha Z35.
Kodi Z15, Z25, ndi Z35 Amatanthauza Chiyani?
Maguluwa akuyimira chitsulo kudzera-kuchepetsa makulidwe a madera. Z -zokwera kwambiri zimatanthawuza kukhazikika kwabwinoko, kukana kung'ambika kwa lamellar, komanso kudalirika kowotcherera.

Zolakwa Zogula Wamba
Magulu ambiri ogula zinthu amalakwitsa kuyitanitsa "Q355B steel plate" yokha popanda kutchula Z-zofuna kulowera.
Zotsatira zake, ogulitsa amatha kupereka mbale wamba, opanga amakumana ndi ming'alu yowotcherera, ndikukonza malo kumakhala kokwera mtengo kwambiri. Ichi ndichifukwa chake kuwunika{1}}zipani zachitatu kuyenera kuyamba pakupeka, osati pambuyo pake. Nthawi zina, vuto limapezeka pokhapokha kukhazikitsa. Panthawi imeneyo, kukonzanso kumakhala kovuta, kuchedwa kumakhala kosalephereka, ndipo chidaliro cha zomangamanga chimachepa kwambiri.

M'mapulojekiti akunja a EPC, ngakhale zolephera zazing'ono zowotcherera zimatha kuyambitsa mikangano yayikulu.Kuphatikizidwa ndi kukonzekera kosakwanira, zolephera izi zimachulukirachulukira.
Kukonzekera: Momwe Ogula Akatswiri Amapewera Chiwopsezo Ichi
Ogula zitsulo odziwa bwino komanso makontrakitala a EPC amawongolera ngoziyi kuyambira pachiyambi. Monga wamalonda wanthawi zonse amene ali ndi malo ochitira zinthu komanso ogwirizana ndi makampani akuluakulu-a boma, timakhazikitsa ndondomeko izi pazantchito zathu zolemetsa{2}}zotumiza kunja.
- Nenani Z-Zofunika Mayendedwe Mwachimvekere:Osangoyitanitsa "mbale yachitsulo ya Q355." M'malo mwake, tchulani Q355B Z15, Q355D Z25, kapena Q355E Z35, kutengera zomwe polojekiti ikufuna.
- Yang'anirani Makulidwe a Mbale Mosamala:Mbaleyo ikamachuluka, ndiye kuti ngoziyo imakhala yokulirapo. Mapulojekiti ogwiritsira ntchito 20mm+, 40mm+, 60mm+, kapena ultra-heavy plates ayenera kuunika mozama pogwiritsa ntchito{8}}zofunika za makulidwe.

Final Takeaway
M'mapulojekiti olemera achitsulo, mphamvu yokhayokha sikokwanira. Chitsulo chachitsulo chikhoza kukwaniritsa zofunikira za mphamvu zokolola pamene chikulephera mkati mwa kuwotcherera. Ichi ndichifukwa chake mapulojekiti azamakampani amasamala kwambiri-zochita zonenepa, Z-kuyesa mayendedwe, komanso kukana kupsinjika kwa welding.
Pazinthu zolemetsa kwambiri, kusankha mbale yolakwika sikulakwa chabe. Ndichiwopsezo chapangidwe. Ndipo m'mapulojekiti akumayiko akunja, zowopsa zobisika zimatha kukhala zovuta zama projekiti.
