I-HEADING-TYPE-1Ithuluzi "le-high-carbon high-alloy kanye nensimbi yokubunjwa emfushane yocwaningo lobuchwepheshe

Umhlangano wokuhlolwa kwempumelelo yobuchwepheshe "we-high-carbon high-alloy alloy kanye ne-mold steel short process short process technology research and development and industrialization" umhlangano wokuhlola impumelelo yobuchwepheshe wabanjwa ngempumelelo ngomhla ka-21 Septhemba 2023. Ochwepheshe beKomidi Lokuhlola Le-Chinese Society for Metals benze ukuhlolwa kwenkundla futhi ukuxhumana okuningiliziwe nabasebenzi bophiko lokuphothula. Kamuva, u-Zhao Ming, umphathi jikelele we-China Resources Steel, ubike ngombiko wezobuchwepheshe wale phrojekthi, umbiko wokusetshenziswa, ubufakazi benzuzo, kanye nombiko omusha wobuchwepheshe. Ochwepheshe bekomiti lokuhlola babuze futhi baxoxisana ngezinqubo ezintsha zephrojekthi kanye nobuchwepheshe ngamunye ngamunye futhi bavumelana ngazwi linye ukuthi ukusungulwa kwephrojekthi kungokulandelayo:

● Ucwaningo nokuthuthukiswa kwenqubo entsha yokukhiqiza okungabizi kakhulu, okusebenza kahle kakhulu kwethuluzi le-alloy ephezulu ye-carbon high-alloy nezinsimbi zokubunjwa, okuhlanganisa ukuncibilika nge-90-ton ultra-high-power electric arc furnace, i-LF+ Ukucwengwa kwe-VD, ukulingisa okuqhubekayo, kanye nokugingqika komlilo owodwa, kuzuze ukukhiqizwa kwenani elikhulu elizinzile.

● Ukuphumelela kobuchwepheshe bokuphonsa obuqhubekayo bethuluzi le-alloy ephezulu ye-carbon high-alloy nezinsimbi zokubunjwa, ukuthuthukiswa kobuchwepheshe obufana nokulawula izinga lokushisa eliqondisa ama-slab, ukunyakazisa kazibuthe ku-crystallizer kanye nezindawo zokupholisa zesibili, kanye ne-low-alkalinity protective slag, kunike amandla ukukhiqizwa kokusakazwa okuqhubekayo okuqhubekayo kwe-high-carbon high-alloy cold work mold steel flat billets kanye namabhilidi esikwele ensimbi anesivinini esikhulu.

● Ucwaningo nokuthuthukiswa kobuchwepheshe bokugoqa obunomlilo owodwa wethuluzi le-alloy ephezulu ye-carbon high-alloy kanye nensimbi eyisicaba eyisicaba, okuzuze ukugoqeka okukodwa komlilo okungu-100~750mm ngokuqhubekayo okusahlela ama-slabs ensimbi yensimbi ene-high-carbon high-alloy work mold. ensimbini eyisicaba eqediwe ewugqinsi engu-10 ~ 50mm kanye nokugingqika komlilo owodwa okungu-150mm kwensimbi enesivinini esikhulu ngokuqhubekayo kuphonsa amabhilidi ayisikwele kuzinti zocingo eziqediwe ezingu-Φ11mm. Lobu buchwepheshe bukhulise isivuno sokukhiqiza ngaphezu kwe-10% futhi bufinyeza umjikelezo wokukhiqiza ngezinsuku ezingaphezu kwezingu-30. Ikomidi elihlolayo likholelwa ukuthi impumelelo yalo phrojekthi iyonke isifinyelele ezingeni elihamba phambili emhlabeni jikelele.
