● Izicelo: Hlangana nezidingo zokuthwala umthwalo kanye nokuzamazama komhlaba kumaphrojekthi wengqalasizinda emikhulu.
Izinto Eziyisisekelo Zezimboni Ezenza Ngokunembayo
I-SWRH72A High-Carbon Steel Wire Rods:
● Ukwakheka Kwekhemikhali: C 0.70–0.75%, Si 0.15–0.35%, Mn 0.50–0.80%
● Amapharamitha Emishini: Amandla aqinile ≥1200 MPa, amandla esivuno ≥900 MPa, ukuncipha kwendawo ≥40%
● Izicelo: Isetshenziswa ezintanjeni zezintambo zensimbi, iziphethu zokumiswa kwezimoto, kanye nokukhiqizwa kwentambo yamasondo e-radial.
I-SAE1008 Cold-Heading Steel Wire Rods:
● Ukulawulwa Kwezinto: C 0.06–0.10%, Mn 0.30–0.50%, P/S ≤0.030%
● I-Ductility Metrics: Ubude ≥30%, ukuncishiswa kwendawo ≥65%
● Izici Zokucubungula: Isihloko esibandayo esinembayo esiphezulu sokukhiqiza amabhawodi anamandla aphezulu, ama-bearing, nezingxenye zehadiwe, okuhlinzeka ngoxhaxha lwezimpahla zezimoto nezasekhaya.
I-Special Alloy Wire Rods for Extreme Conditions
30 CrMo Alloy Wire Rods:
● Ukwakhiwa Kwengxubevange: C 0.26–0.34%, Cr 0.80–1.10%, Mo 0.15–0.25%
● Ukusebenza Kwezinga Lokushisa Eliphezulu: Amandla okukhiqiza ≥550 MPa ku-550°C, amandla aqinile ≥930 MPa ekamelweni lokushisa
● Izinhlelo zokusebenza: Ukugqwala nokumelana nokushisa kwezintambo zikawoyela zokumba, amabhawodi okunamathisela we-wind turbine tower, nezibophelelo zasemkhathini.
I-BZn18-18 Izintambo Zocingo Ezivunyiwe:
● I-Base Material: C ≤0.08%, Cu 0.25–0.40%, Zn 18–20%
● Amapharamitha Wokuhlanganisa: I-Galfan® alloy coating (Zn-5%Al-RE), isisindo sokunamathela 200–300 g/m²
● I-Conductivity: Kusetshenziswa kumakhebuli egridi yamandla kanye nothango oluvikelayo lwezindawo ezingaphandle.
Izinzuzo Zenqubo kanye Nemihlahlandlela Yokukhetha Okubalulekile
Ubuchwepheshe bokupholisa obusezingeni eliphezulu nesivinini esilawulwayo buqinisekisa ukunemba kobukhulu (±0.1 mm) kanye ne-microstructural homogeneity, esekela izinqubo ezansi nomfula njengokudweba nokwelashwa kokushisa. Ukukhethwa kwezinto ezibonakalayo kufanele kuhambisane nezindinganiso zomkhakha (ASTM, GB/T, JIS), ukubeka kuqala okuqukethwe kwekhabhoni, ukunwetshwa, nokulawula ukonakala kwendawo.
Njengomphakeli wezintambo zocingo zomhlaba wonke, siletha izixazululo ezinobubanzi obugcwele bezintambo zensimbi, izingxenye ezijwayelekile ezinekhanda elibandayo, nezinto zocingo lwe-alloy ezikhethekile, sinikeza amaklayenti amandla okunciphisa izindleko futhi athuthukise ukusebenza kahle. Xhumana nathi manje ukuze uthole amakhathalogi emikhiqizo eyenziwe ngokwezifiso kanye nokwesekwa kobuchwepheshe!
