China High khalidwe mpweya structural zitsulo, aloyi structural zitsulo ndi zosapanga dzimbiri zosagwira zitsulo mkulu kuthamanga msokonezo chitoliro cha nthunzi kukatentha mapaipi pansi pa kupsyinjika ndi pamwamba pa kukanikiza Mlengi ndi Supplier

Mpweya wapamwamba kwambiri wa carbon structural steel, aloyi structural chitsulo ndi chitsulo chosapanga dzimbiri chosasunthika ndi chitoliro chosasunthika chopanda chitoliro cha mapaipi otenthetsera nthunzi pansi pa kupanikizika kwambiri

Mpweya wapamwamba kwambiri wa carbon structural steel, aloyi structural chitsulo ndi zitsulo zosapanga dzimbiri zosagwira kutentha, chitoliro chopanda phokoso cha mapaipi otenthetsera nthunzi pansi pa kupanikizika kwambiri

Kufotokozera Kwachidule:

Njira yopanga:

(1) General GB9948 opanda zitsulo chitoliro kutentha ndi pansipa 450 ℃, chitoliro zoweta makamaka zopangidwa ayi. 10, 20 carbon bonded zitsulo otentha adagulung'undisa chitoliro kapena ozizira kukokedwa chitoliro.

②GB9948 chitoliro chosasunthika chachitsulo chimagwiritsidwa ntchito pa kutentha kwambiri komanso kupanikizika kwambiri, chitoliro chimagwira ntchito ya mpweya wotentha kwambiri ndi mpweya wa madzi, okosijeni ndi dzimbiri zidzachitika. Chitoliro chachitsulo chimayenera kukhala ndi mphamvu zolimba kwambiri, kukana kwamphamvu kwa okosijeni. ndi kukhazikika kwa microstructure.

(2) gwiritsani ntchito:

(1) General GB9948 chitoliro chosasunthika chopanda chitsulo chimagwiritsidwa ntchito kwambiri popanga chitoliro cha khoma lamadzi, chitoliro chamadzi otentha, chitoliro chamadzi otentha, chitoliro chamoto chotenthetsera, chitoliro chachikulu ndi chaching'ono chautsi ndi chitoliro cha njerwa.

②GB9948 chubu chachitsulo chosasunthika chimagwiritsidwa ntchito makamaka popanga chubu chapamwamba kwambiri, chubu chotenthetsera, chitoliro, chitoliro chachikulu cha nthunzi ndi zina zambiri zoponderezedwa kwambiri ndi boiler yothamanga kwambiri.

GB9948 chubu chosasunthika chachitsulo molingana ndi magwiridwe antchito apamwamba amagawidwa mu chubu cha boiler ndi chubu chachikulu cha boiler.

Mafotokozedwe ndi maonekedwe abwino

Chofunikira Choyesa

Mayeso a Hydraulic
Kuyesa kwa hydraulic kudzachitika pamipope yachitsulo imodzi ndi imodzi. Kuthamanga kwakukulu kwa mayeso ndi 20 MPa. Pansi pa kukakamizidwa kwa mayeso, nthawi yokhazikika sikhala yochepera 10 s, ndipo kutayikira kwa chitoliro chachitsulo sikuloledwa.
Mayeso osalala
Mayeso a flattening ayenera kuchitidwa kwa chitoliro chachitsulo chokhala ndi m'mimba mwake kuposa 22 mm
Kuyesa kwamoto
Chitsulo chapamwamba cha carbon structural ndi zitsulo zosapanga dzimbiri (zosatentha) zokhala ndi mainchesi akunja osapitilira 76 mm ndi makulidwe a khoma osapitilira 8 mm ziyenera kuyesedwa. Kuyesa kwa flaring kumayenera kuchitidwa kutentha. Kuwotcha kwakunja kwachitsanzo pambuyo pa 60% ya kuphulika kudzakwaniritsa zofunikira za tebulo 7. Palibe ming'alu kapena ming'alu yomwe imaloledwa pa chitsanzo pambuyo pa kuwomba. Malinga ndi zomwe amafuna ndi zomwe zanenedwa mu mgwirizano, chitsulo chopangidwa ndi alloy chitha kugwiritsidwanso ntchito pakukulitsa mayeso.
Ma testes osawononga
Mipope yachitsulo iyenera kuzindikiridwa ndi akupanga cholakwika chimodzi ndi chimodzi malinga ndi zomwe GB / T 5777-2008. Malinga ndi zofunikira za wofunsayo, mayesero ena osawononga amatha kuwonjezeredwa pambuyo pokambirana pakati pa wogulitsa ndi wofunayo ndipo akuwonetsedwa mu mgwirizano.
Intergranular dzimbiri mayeso
Kuyesa kwa dzimbiri kwa intergranular kudzachitika kwa chitoliro chachitsulo chosapanga dzimbiri (chopanda kutentha). Njira yoyesera idzakhala molingana ndi zomwe zimaperekedwa ndi njira yaku China E mu GB / T 4334-2008, ndipo chizolowezi cha dzimbiri cha intergranular sichiloledwa pambuyo pa mayeso.
Pambuyo pokambirana pakati pa wogulitsa ndi wofuna, komanso zomwe zalembedwa mu mgwirizano, wofunsayo atha kusankha njira zina zoyesera zowonongeka.
