Chitoliro cha boiler chili ndi zitsulo zamagulu awa: SA179, SA192, SA335, GB5310

amagwiritsidwa ntchito mosiyanasiyana. Ndipo nthawi zambiri Zida zitha kugwiritsidwa ntchito mosinthana.

Mwachitsanzo:

GB5310 : 15CrMo G = A335 P12 = En10216-2 13CrMo4-5

Koma mtengo ndi wosiyana monga muyezo wosiyana. Yotsika mtengo kwambiri ndi 15CrMoG. ndi pafupifupi 150-300 US dollar kusiyana.

Chifukwa chake Mumsika, pali makasitomala ena nthawi zambiri amatenga mtengo wotsika mtengo kuti achotse.

Kugwiritsa ntchito

Amagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon structural steel, alloy structural chitsulo ndi mapaipi achitsulo osatentha osagwira kutentha osasunthika kuti azitha kuthamanga kwambiri komanso mapaipi otenthetsera pamwamba.

Amagwiritsidwa ntchito kwambiri pakuthamanga kwambiri komanso kutentha kwambiri kwa boiler (chubu chapamwamba chotenthetsera, chubu chotenthetsera, chubu chowongolera mpweya, chubu chachikulu cha nthunzi yama boiler okwera komanso okwera kwambiri). Pansi pa kutentha kwa mpweya wa flue ndi mpweya wa madzi, chubucho chidzasungunuka ndi kuwononga. Ndikofunikira kuti chitoliro chachitsulo chikhale chokhazikika kwambiri, kukana kwambiri makutidwe ndi okosijeni ndi dzimbiri, komanso kukhazikika kwadongosolo.

Main Grade

Kalasi apamwamba mpweya structural zitsulo: 20g, 20mng, 25mng

Kalasi ya aloyi structural zitsulo: 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, 12cr3movsitib, etc.

Kulekerera

Makulidwe a Khoma ndi Diameter Yakunja:

Ngati palibe zofunikira zapadera, chitolirocho chidzaperekedwa ngati m'mimba mwake wakunja ndi makulidwe a khoma. Monga tsamba lotsatira

Utali:

Utali wanthawi zonse wa mipope yachitsulo ndi 4 000 mm ~ 12 000 mm. Pambuyo pokambirana pakati pa wogulitsa ndi wogula, ndikudzaza mgwirizanowu, ukhoza kuperekedwa mapaipi achitsulo ndi kutalika kwa 12 000 mm kapena kufupikitsa kuposa I 000 mm koma osachepera 3 000 mm; kutalika kwapang'onopang'ono Kuchuluka kwa mapaipi achitsulo osakwana 4,000 mm koma osachepera 3,000 mm sikuyenera kupitilira 5% ya kuchuluka kwa mapaipi achitsulo omwe amaperekedwa.

Kulemera kwake:
Pamene chitoliro chachitsulo chimaperekedwa molingana ndi m'mimba mwake mwadzina ndi makulidwe a khoma lodziŵika kapena m'mimba mwake mwadzina ndi makulidwe a khoma, chitoliro chachitsulo chimaperekedwa molingana ndi kulemera kwake. Itha kuperekedwanso molingana ndi kulemera kwamalingaliro.
Pamene chitoliro chachitsulo chimaperekedwa molingana ndi m'mimba mwake mwadzina ndi makulidwe ochepa a khoma, chitoliro chachitsulo chimaperekedwa molingana ndi kulemera kwake; maphwando ogulitsa ndi ofunikira amakambirana. Ndipo zikuwonetsedwa mu mgwirizano. Chitoliro chachitsulo chikhoza kuperekedwanso molingana ndi kulemera kwa chiphunzitso.

Kulekerera kulemera:
Malinga ndi zofunikira za wogula, pambuyo pokambirana pakati pa wogulitsa ndi wogula, ndi mu mgwirizano, kupatuka pakati pa kulemera kwake ndi kulemera kwake kwa chitoliro chachitsulo kudzakwaniritsa zofunikira izi:
a) Chitoliro chachitsulo chimodzi: ± 10%;
b) Gulu lililonse la mapaipi achitsulo okhala ndi kukula kochepa kwa 10 t: ± 7.5%.

Chofunikira Choyesa

Mayeso a Hydraustatic:

Chitoliro chachitsulo chiyenera kuyesedwa hydraulically mmodzimmodzi. Kuthamanga kwakukulu kwa mayeso ndi 20 MPa. Pansi pa kukakamizidwa kwa mayeso, nthawi yokhazikika iyenera kukhala yosachepera 10 s, ndipo chitoliro chachitsulo sichiyenera kutuluka.

Wogwiritsa ntchito akavomera, kuyesa kwa hydraulic kumatha kusinthidwa ndi kuyesa kwa eddy panopa kapena kuyesa kwa maginito kutayikira.

Mayeso Osawononga:

Mipope yomwe imafuna kuyang'anitsitsa kwambiri iyenera kuyang'aniridwa ndi ultrasonically mmodzimmodzi. Pambuyo pa zokambiranazo zimafuna chilolezo cha chipanicho ndipo zafotokozedwa mu mgwirizano, mayesero ena osawononga akhoza kuwonjezeredwa.

Mayeso a Flattening:

Machubu okhala ndi mainchesi akunja opitilira 22 mm adzayesedwa kuphwanyidwa. Palibe delamination yowoneka, mawanga oyera, kapena zonyansa zomwe ziyenera kuchitika panthawi yonse yoyesera.

Kuyesa kwa Flaring:

Malinga ndi zofunika za wogula ndi ananena mu mgwirizano, chitoliro zitsulo ndi awiri akunja ≤76mm ndi khoma makulidwe ≤8mm akhoza kuchita flaring mayeso . Kuyesera kunkachitika kutentha kwa chipinda ndi taper ya 60 °. Pambuyo pakuwotcha, kutentha kwapakati pakunja kuyenera kukwaniritsa zofunikira patebulo lotsatirali, ndipo zoyeserera siziyenera kuwonetsa ming'alu kapena ming'alu.
