Il-karozzaHot Dip Galvalume Steel Coil unità tiffoka fuq il-produzzjoni ta 'pjanċi ta' barra. Il-ħxuna tal-ispeċifikazzjonijiet tal-prodott hija l-aktar bejn 0.6 u 1.2mm, il-wisa 'tal-pjanċa hija l-aktar 800 sa 1850mm, u l-aktar wiesgħa tista' tilħaq 2000mm. Il-livell tal-prodott huwa pjuttost kumpless, minn CQ, DQ, DDQ, EDDQ (IF) sa BH, DP, TRIP, u pjanċi ta' l-azzar ta' saħħa-għoli tal-karozzi. Bl-użu ta 'varjetà ta' teknoloġiji avvanzati, il-morfoloġija tal-kisi u l-eżattezza tal-ħxuna jistgħu jiġu kkontrollati b'mod preċiż, bħall-iżball tal-ħxuna tal-kisi huwa inqas minn 23g/m2. Barra minn hekk, il-pjanċa tal-azzar mingħajr-żingu tista' tiġi prodotta bl-użu ta' galvanizzar-ħieles taċ-ċomb. Dan it-tip ta 'kisi mhuwiex faċli biex jipproduċi korrużjoni intergranulari u għandu ħajja twila ta' servizz. Għalhekk, huwa adattat għall-industriji tal-karozzi u tat-tagħmir elettriku. Kważi kull unità tal-galvanizzar bis-sħana-dip fil-Ġappun hija mgħammra b'forn tal-liga taż-żingu-ħadid. Il-ħxuna standard tas-saff galvanizzat tal-pjanċa tal-liga taż-żingu-ħadid (Galavneal) hija 160180g/m2 fuq iż-żewġ naħat, u l-kisi tal-liga fih Fe8 fil-mija 12 fil-mija 2.
Foreign countries developed micro-alloy steel and phosphorous alloy steel in the 1970s, bidirectional DP steel and bake hardening steel in the mid-1980s, and phase transformation and induced plasticity TRIP steel in the 1990s 3. At present, the international cooperation project "Ultra-Lightweight Steel Carbody (ULSAB) Development" is proceeding smoothly. Its goal is to achieve a driving fuel consumption of 34KM/3L (US) and a car bodyweight reduction of 25 percent . The primary starting point is to adopt many high-strength and ultra-high-strength steel plates in the car body structure. The most prominent feature of the ultra-light steel car body through the large ULSAB is that it does not sacrifice performance to reduce the car's weight 4. The design basis of ultra-light steel vehicles is that the proportion of high-strength steel used in the body structure exceeds 90 percent . During the ten years from 1985 to 1995, high-strength steel in the body increased from 10 percent to 30 percent . With the surface treatment performance, The improvement of automobile life span extends from 6.7 years to 9.3 years. After deducting the energy increase in the manufacture of high-performance steel plates, 357104L of heavy oil can save a year, which is almost equivalent to saving a percentage of the energy consumption of the domestic steel industry. A few. In 2000, the use of high-strength steel plates in Japanese automobile manufacturing reached 36.3 percent .
