Ndizodziwika bwino kuti mawonekedwe, kuthekera kogwira ntchito, ndi nthawi yogwirira ntchito ya chinthu ndi chizindikiro cha luso la chinthu, ndipo ndi zinthu zitatu zazikulu zowunikira zabwino ndi zoyipa za chinthu. Mu kope lomaliza, tinakufotokozerani za kusintha kwa njira yopangira ntchito ya Heli Heavy Industries komanso momwe zinthu zidzayendere mtsogolo ndi mutu wakuti "Chitukuko Chatsopano, Njira Yatsopano". Mu kope lino, tikuwonetsani zinthu za Heli Heavy Industries kuchokera ku zipangizo ndi njira zakale.
Kuchuluka kwa zinthu za mankhwala nthawi zonse kwakhala muyeso wa ubwino wa zipangizo zachitsulo. Mwachitsanzo, kuwonjezeka kwa mpweya wa kaboni muchitsulo kudzawonjezera mphamvu ya chitsulocho komanso mphamvu yake yokoka, pamene kumachepetsa pulasitiki yake ndi mphamvu zake zogwirira ntchito.
Pa mzere umodzi wopangira zinthu ku Heli Heavy Industry, pali madipatimenti awiri oyesera. Dipatimenti yoyamba yoyesera ili mu fakitale, ndipo imayang'anira kuyang'anira zosakaniza za zinthu ndi kuyang'anira zinthu zopanda kanthu. Dipatimenti yachiwiri yoyesera ili ku Heli. Malo opangira zinthu ku Li Heavy Industry makamaka amayang'anira kuyang'anira nthawi zonse zinthu zomalizidwa komanso kuthandizira kuyang'anira njira yochizira kutentha. Laboratory ili ndi chowunikira cha kaboni ndi sulfure, chowunikira chanzeru cha zinthu zambiri, maikulosikopu yachitsulo, ndi zina zotero.
Chowunikira cha 6801-BZ/C cha Arc Combustion Carbon ndi Sulphur
Choyezera mpweya ndi sulfure cha 6801-BZ/C arc chidzasanthula molondola kuchuluka kwa kaboni ndi sulfure m'zinthuzo. Kuwonjezera pa momwe kaboni umakhudzira kuuma ndi pulasitiki ya chitsulo, chimakhudzanso kukana dzimbiri kwa chitsulocho mumlengalenga. Mu malo akunja, kuchuluka kwa kaboni kumakhala kwakukulu, kumakhala ndi mwayi woti chingawonongeke. Chifukwa chake, kudziwa kuchuluka kwa kaboni ndi gawo lofunikira pakupanga chitsulo. Sulfure ndi chinthu chowopsa pazochitika wamba. Chimapangitsa chitsulocho kupanga kufooka kotentha, chimachepetsa kulimba kwa chitsulocho, komanso chimayambitsa ming'alu panthawi yopangira ndi kugubuduza. Sulfure imawononganso magwiridwe antchito a welding, kuchepetsa kukana dzimbiri. Komabe, kuwonjezera sulfure ya 0.08-0.20% kuchitsulo kungathandize kukonza makina ndipo nthawi zambiri amatchedwa chitsulo chodula.
6811A wanzeru wosanthula zinthu zambiri
Chowunikira zinthu zambiri cha 6811A chanzeru chimatha kuyeza molondola kuchuluka kwa zinthu zosiyanasiyana monga manganese (Mu), silicon (Si), ndi chromium (Cr). Manganese ndi deoxidizer yabwino komanso desulfurizer popanga chitsulo. Kuwonjezera manganese okwanira kungathandize kukana kuwonongeka kwa chitsulo. Silicon ndi chinthu chabwino chochepetsera komanso deoxidizer. Nthawi yomweyo, silicon imatha kuwonjezera kwambiri malire a elasticity a chitsulo. Chromium ndi chinthu chofunikira kwambiri cha alloy cha chitsulo chosapanga dzimbiri komanso chitsulo chosagwira kutentha. Imatha kuwonjezera kuuma ndi kukana dzimbiri kwa chitsulo, koma nthawi yomweyo imachepetsa pulasitiki. Chifukwa chake, kusweka kwachitsulo komwe kumachitika panthawi yochizira kutentha kungakhale kuchuluka kwa chromium.
Maikulosikopu yachitsulo
Pakupanga malo okhala ndi mawilo anayi, zinthu zomwe zili pansi pa mawilo othandizira, chivundikiro cha mbali ya mawilo othandizira ndi chothandizira cha mawilo otsogolera ndi chitsulo chosungunuka, chomwe chili ndi zofunikira kwambiri pa kuchuluka kwa mawilo ozungulira. Maikulosikopu yachitsulo imatha kuwona mwachindunji kuchuluka kwa mawilo ozungulira.
Kuphatikiza apo, nickel (Ni), molybdenum (Mo), titaniyamu (Ti), vanadium (V), tungsten (W), niobium (Nb), cobalt (Co), mkuwa (Cu), aluminiyamu (Al), Kuchuluka kwa zinthu monga boron (B), nayitrogeni (N), ndi rare earth (Xt) zonse zidzakhudza magwiridwe antchito a chitsulo ndipo ziyenera kulamulidwa mkati mwa malire enaake.
Ma laboratories awiriwa ali ngati malo awiri owunikira zinthu za msonkho, amayang'anira nthawi zonse zipangizo za Heli, amaletsa kutuluka kwa zinthu zonse zosafunikira, komanso amapereka zinthu zoyenera komanso zapamwamba kwa makasitomala.
