Ngokweendlela zokwenziwa kweshishini kwicandelo loomatshini abanzima, ukubunjwa kwasimahla okuveliswe kusetyenziswa oomatshini bokushicilela behydraulic obunomthamo wokwenza ngaphezulu kwe-1000 yeetoni kunokubhekiswa kubo njengokwenza okukhulu. Ngokusekwe kwisakhono sokwenza oomatshini bokushicilela behydraulic ukufoja simahla, oku kungqamana ngokulinganayo neshaft forgings enobunzima obungaphezulu kweetoni ezi-5 kunye nediskhi yokufogina enobunzima obungaphaya kweetoni ezi-2.
Iimpawu eziphambili kunye nezisisiseko ze-forgings ezinkulu ziyimilinganiselo yazo enkulu kunye nobunzima obunzima. Umzekelo, ubungakanani be-600MW yejenereyitha yejeneretha ye-rotor yokubunjwa yi-φ1280mm×16310mm, enobunzima be-111.5 tons. Ubungakanani be-2200-2400MW yejenereyitha yejenereyitha yejenereyitha yokubunjwa yi-φ1808mm×16880mm, inobunzima obuziitoni ezingama-247.
Ngenxa yobukhulu kunye nobunzima babo, iifogi ezinkulu kufuneka zenziwe ngokuthe ngqo kwiingots ezinkulu zetsimbi. Kuyaziwa ukuba i-ingots ezinkulu zetsimbi zihlala zinemiba enzulu efana nokuhlukana, i-porosity, i-shrinkage, i-non-metallic inclusions, kunye neentlobo ezahlukeneyo zesakhiwo esingafaniyo. Kwakhona bavame ukuba nomxholo ophezulu wegesi, kwaye ezi ziphene kunzima ukuzisusa ngexesha leenkqubo zokubumba ezilandelayo. Ngenxa yoko, ukubunjwa kweekhemikhali okubalulekileyo okungafaniyo, iziphene ezahlukeneyo zesakhiwo, kunye namanqanaba aphezulu omxholo werhasi enobungozi zihlala zikhona kwiifogi ezinkulu. Oku kwenza inkqubo yonyango lobushushu kwi-forgings enkulu entsonkothileyo, idla ixesha, kwaye iyabiza. Ngoko ke, ingqwalasela engqongqo kufuneka ihlawulwe ngexesha lokunyanga ukushisa.
Ngaphezu koko, ngenxa yobukhulu kunye nobunzima babo, i-forgings enkulu inomthamo ophezulu kakhulu wokushisa, okwenza kube nzima ukufezekisa amazinga aphezulu okufudumeza kunye nokupholisa ngexesha lonyango lobushushu. Ngoko ke, kwi-forgings enkulu efuna utshintsho olubalulekileyo kwisakhiwo sangaphakathi ngokufudumeza okanye ukucima ukuhlangabezana neemfuno eziphezulu zokusebenza kunye nomgangatho, i-austenite ezinzileyo kakhulu kunye ne-high hard hardability steels kufuneka isetyenziswe. Imizekelo ibandakanya i-Ni-Cr-Mo, i-Ni-Mo-V, kunye ne-Ni-Cr-Mo-V series steels. Nangona kunjalo, iintsimbi ezinozinzo oluphezulu lwe-austenite ye-supercooled zithandeka kwilifa lesakhiwo, okukhokelela kubukhulu oburhabaxa kunye nokungalingani okuziinkozo kwi-alloy steel forgings. Ukujongana nalo mbandela, iinkqubo ezikhethekileyo kunye neziyinkimbinkimbi zokunyanga ukushisa zihlala zifunwa.
Ukuba ufuna ulwazi oluthe kratya malunga ne-WELONG forgings ye-injini yomphunga kunye nejenereyitha, zive ukhululekile ukuqhagamshelana
