Uhlaziyo olukhokelwa yi-China yemigangatho yamazwe ngamazwe kwintsimi yeepleyiti zetsimbi kunye nemicu epapashwe ngokusemthethweni

Umgangatho wacetywa ukuba uhlaziywe kwi-2022 kwintlanganiso yonyaka ye-ISO/TC17/SC12 Steel/Continuous Rolled Flat Products Sub-Committee, kwaye yasungulwa ngokusesikweni ngoMatshi 2023. Iqela elisebenzayo lokuyila lathatha iminyaka emibini enesiqingatha, apho intlanganiso yeqela elisebenzayo kunye neentlanganiso ezimbini zonyaka zabanjwa kwiingxoxo ezinzulu, kunye nokuhlaziywa kwe-ISO20, ngo-Aprili 20, ukuhlaziywa kwe-ISO20. 4997:2025 "IBanga loLwakhiwo lweBanga eliQonxileyo leCarbon Thin Steel Plate" langeniswa.

Lo mgangatho ngomnye uhlaziyo olusemgangathweni lwamazwe ngamazwe olukhokelwa yi-China emva kokuba i-China ithathe usihlalo we-ISO/TC17/SC12. Ukukhutshwa kwe-ISO 4997: I-2025 enye impumelelo kwi-China yokuthatha inxaxheba kumsebenzi wokulinganisa ngamazwe ngamazwe kwintsimi yeeplate zetsimbi kunye nemichilo emva kwe-ISO 8353: 2024.

Ikhabhoni yolwakhiwo lwentsimbi ebandayo ipleyiti yentsimbi eqengqelekayo kunye neemveliso zemicu ziye zazibophelela ekuphuculeni amandla kunye nokunciphisa ubukhulu, ngaloo ndlela kuncitshiswa ubunzima beemveliso zokuphela, ukufikelela usukelo lokugqibela lokonga amandla kunye nokunciphisa ukukhutshwa, kunye nokuqonda ingcamango yokuvelisa "yentsimbi eluhlaza". Inguqulelo ye-2015 yomgangatho weyona marike isetyenziswa kakhulu amandla esivuno samabakala entsimbi angama-280MPa ayichazwanga. Ukongezelela, imixholo yobugcisa bomgangatho, njengobunzima bomhlaba kunye nobunzima bebhetshi, ayihlangabezani neemfuno zangempela zemveliso yangoku. Ukuze kuphuculwe ngakumbi ukusebenza komgangatho, iZiko loPhando ngeMigangatho yoMgangatho woShishino lweMetallurgical laququzelela i-Anshan Iron & Steel Co. ukuba ifake isicelo seprojekthi entsha esemgangathweni yamazwe ngamazwe yale mveliso. Kwinkqubo yohlaziyo, iimfuno zobugcisa zebakala elitsha ziye zamiselwa ngokubonisana neengcali ezivela eJapan, eJamani naseUnited Kingdom amaxesha amaninzi, bezama ukuhlangabezana neemfuno zemveliso kunye nokuhlolwa kwilizwe ngalinye kunye nokwandisa umda wokusetyenziswa komgangatho.
