Sing'anga ndi otsika kuthamanga zitsulo chitoliro anapanga China
(1) Gb3087-82 machubu achitsulo opanda msoko a ma boiler otsika komanso apakatikati. Kuyesedwa kolimba kumayenderana ndi GB / t228-87, kuyesa kwa hydrostatic ndi GB / t241-90, kuyesa kwa flattening ndi GB / t246-97, kuyesa kwamoto ndi GB / t242-97 ndi kuyesa kozizira kozizira ndi gb244-97.
(2) Gb5310-95 machubu opanda zitsulo osasunthika a ma boilers othamanga kwambiri. Kuyesa kwamphamvu, kuyesa kwa hydraulic ndi kuyesa kwa flattening ndizofanana ndi zomwe zafotokozedwa mu gb3087-82; Kuyesa kwamphamvu molingana ndi gb229-94, kuyesa kwamoto molingana ndi GB / t242-97 ndi kuyesa kukula kwambewu molingana ndi Yb / t5148-93; Kuyang'ana kwa Microstructure kudzakhala molingana ndi gb13298-91, kuyendera kwa decarburized layer kudzakhala molingana ndi gb224-87, ndipo kuyang'anira akupanga kudzakhala molingana ndi GB / t5777-96.
(3) Kuwunika kwa magwiridwe antchito ndi ma index a machubu otenthetsera omwe amatumizidwa kunja kudzachitika molingana ndi miyezo yoyenera yomwe yafotokozedwa mu mgwirizano (1) Maiko akulu omwe amalowetsa machubu otenthetsera ndi Japan ndi Germany. Zomwe zimatumizidwa kawirikawiri ndi 15914.2mm; 2734.0mm; 219.110.0mm; 41975 mm; 406.460mm, etc. Zochepa zochepa ndi 31.84.5mm, ndipo kutalika kwake ndi 5 ~ 8m.
(2) Pankhani yofuna kuitanitsa, machubu otenthetsera opanda mpweya a ST45 omwe adatumizidwa kuchokera ku fakitale yachitsulo ya Mannesmann ku Germany adapezeka kuti ali ndi zolakwika zamkati mopitilira malamulo a chomeracho komanso miyezo ya German iron and Steel Association.
(3) Mapaipi azitsulo a aloyi omwe amatumizidwa kuchokera ku Germany amakhala makamaka 34CrMo4 ndi 12CrMoV. Chitoliro chachitsulo chamtunduwu chimakhala ndi ntchito yabwino yotentha kwambiri ndipo nthawi zambiri imagwiritsidwa ntchito ngati chitoliro chachitsulo cha boiler yotentha kwambiri.
(4) Pali mapaipi ambiri a aloyi omwe amatumizidwa kuchokera ku Japan, okhala ndi 426.012mm 5 ~ 8m; 152.48.0mm12m; 89.110.0mm6m; 101.610.0mm12m; 114.38.0mm6m; 127.08.0mm9m, etc. Kukhazikitsa Japanese mafakitale muyezo jisg3458, ndi kalasi zitsulo ndi stpa25. Chitoliro chachitsulo chamtunduwu nthawi zambiri chimagwiritsidwa ntchito ngati chitoliro cha superalloy. Kuthamanga kwakukulu kwachitsulo chopanda chitsulo ndi mtundu wa chitoliro chopanda msoko. Njira yopangira ndi yofanana ndi chitoliro chosasunthika, koma pali zofunikira zokhwima pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga chitoliro chachitsulo. Malinga ndi kutentha kwautumiki, amagawidwa mu chubu cha boiler wamba komanso chubu chopopera kwambiri.
① Kutentha kwautumiki kwa chitoliro chachitsulo chosasunthika chapamwamba ndi pansi pa 450 ℃, ndipo chitoliro chapakhomo chimapangidwa makamaka ndi No. 10 ndi No.
② Kuthamanga kwambiri kwachitsulo chosasunthika chitoliro nthawi zambiri kumakhala kutentha kwambiri komanso kuthamanga kwambiri. The chitoliro adzakhala oxidized ndi dzimbiri pansi pa zochita za mkulu kutentha chitoliro mpweya ndi nthunzi. Chitoliro chachitsulo chimafunika kuti chikhale ndi mphamvu zokhalitsa, anti-oxidation yapamwamba ndi ntchito ya dzimbiri komanso kukhazikika kwadongosolo.
