Ishidi lensimbi ye-ASTM A283

I-ASTM A283 plate steel plate ifaka ipuleti lensimbi yensimbi ephansi futhi emaphakathi yekhwalithi yesakhiwo. Inezinhlobonhlobo ezine ezivamile, ngayinye imelelwa njengento ehlukile. Isigaba sezinto ezibonakalayo ngezansi sibonisa ububanzi obuhlanganisa zonke izinhlobo.

Lokhu kucaciswa kuhlanganisa amabanga amane amapuleti ensimbi ekhabhoni ekhwalithi yesakhiwo ukuze asetshenziswe okuvamile. Amasampula ensimbi azoncibilika acutshungulwe ngesithando somlilo esivulekile, i-basic-oxygen, noma isithando somlilo sikagesi. Ukuhlaziywa kokushisa nomkhiqizo kuzokwenziwa lapho izinto zensimbi zizovumelana nezinhlanganisela zamakhemikhali ezidingekayo zekhabhoni, i-manganese, i-phosphorus, isulfure, i-silicon, nethusi. Izifanekiso zensimbi nazo zizohlolwa ukuthi ziqine kangakanani futhi zizohambisana namanani adingekayo wamandla aqinile, indawo yokukhiqiza, nobude.
