HEADING-TYPE-1Chida cha "high-carbon high-alloy and mold steel short process technology research

The "High-carbon high-alloy tool and mold steel short process technology research and development and industrialization" msonkhano wowunikira kukwaniritsidwa kwaukadaulo udachitika bwino pa Seputembara 21, 2023. Akatswiri a Komiti Yowunika ya Chinese Society for Metals adayendera ndi kuyankhulana mwatsatanetsatane ndi ogwira ntchito pagawo lomaliza. Pambuyo pake, a Zhao Ming, manejala wamkulu wa China Resources Steel, adanenanso za lipoti laukadaulo la polojekitiyi, lipoti lakugwiritsa ntchito, umboni wopindulitsa, komanso lipoti laukadaulo waukadaulo. Akatswiri a komiti yowunika adafunsa ndikukambirana njira zatsopano za polojekitiyi m'modzi ndi m'modzi ndipo adagwirizana kuti zatsopano za polojekitiyi ndi izi:

● Kufufuza ndi chitukuko cha njira yatsopano yopangira zida zotsika mtengo, zopangira mphamvu zapamwamba za carbon high-alloy tool ndi zitsulo za nkhungu, zomwe zimaphatikizapo kusungunula ndi 90-ton ultra-high-power electric arc ng'anjo, LF + Kuyenga kwa VD, kuponyera mosalekeza, ndikugudubuza pamoto umodzi, kwapeza kupanga kokhazikika kokhazikika.

● Kupititsa patsogolo luso lamakono lopangira zida za carbon high-alloy ndi zitsulo za nkhungu, chitukuko cha matekinoloje monga kuwongolera kutentha kwa slab, kusonkhezera kwa maginito mu crystallizer ndi chigawo chachiwiri chozizira, ndi slag yochepetsera alkalinity yotetezera, mogwira mtima mosalekeza kuponyera kupanga mkulu-mpweya mkulu-aloyi ozizira nkhungu nkhungu zitsulo lathyathyathya billets ndi mkulu-liwiro zitsulo lalikulu billets.

● Kafukufuku ndi chitukuko cha teknoloji yamoto umodzi wopangira chida chapamwamba cha carbon high-alloy ndi nkhungu yopyapyala zitsulo, zomwe zakwaniritsa kugudubuza kwamoto umodzi wa 100 ~ 750mm mosalekeza kuponyedwa kwazitsulo zazitsulo za carbon high-alloy cold work mold. mu 10 ~ 50mm wandiweyani womalizidwa chitsulo chathyathyathya ndi kugudubuzika kwamoto umodzi wa 150mm chitsulo chothamanga kwambiri mosalekeza kuponya mabatani akulu mu Φ11mm zomalizidwa zamawaya. Ukadaulo uwu wachulukitsa zokolola zochulukirapo kuposa 10% ndikufupikitsa nthawi yopanga ndi masiku opitilira 30. Komiti yowunikirayi ikukhulupirira kuti zomwe polojekitiyi yakwaniritsa zafika pamlingo wotsogola padziko lonse lapansi.
